Three clinical features distinguish malignant germ cell tumors from epithelial ovarian cancers. Which are ..?

Answer 81

First. individuals typically are younger, usually in their teens or early 20s. Most have stage I disease at diagnosis. Last, prognosis is excellent-even for those with advanced disease–due to exquisite tumor chemosensitivity. Fertility-sparing surgery is the primary treatment for women seeking future pregnancy, although most will require postoperative chemotherapy.

Question 85

the most common ovarian malignancy detected during pregnancy.

Answer 85

Dysgerminoma

Question 85

the most common ovarian malignancy detected during pregnancy.

Answer 85

Dysgerminoma
(This is believed to be an age-related coincidence, however, and not due to gestation)

Question 86

Five percent of ******* are discovered in phenotypic females with karyotypically abnormal gonads, specifically, with a normal or abnormal Y chromosome (Morimura, 1998). Commonly, this group includes those with Turner syndrome mosaicism (45,X/46,XY) and with Swyer syndrome (46,XY, pure gonadal dysgenesis)

Answer 86

dysgerminomas
(The dysgenetic gonads of these individuals often contain gonadoblastomas, which are benign germ cell neoplasms. These tumors may regress or alternatively may undergo malignant transformation, most commonly to dysgerminoma. Because approximately 40 percent of gonadoblastomas in these individuals undergo malignant transformation, both ovaries are removed)

Question 87

Answer 88

Dysgerminoma

Question 89

Dysgerminoma tumor cells closely resemble the primordial germ cell of the embryo and are histologically identical to **** of the testis.

Answer 89

seminoma

Question 90

The standard treatment of dysgerminoma

Answer 90

usually involves fertility-sparing surgery with unilateral salpingo-oophorcctomy (USO). In some extenuating circumstances, ovarian cystectomy may be considered (Vicus, 2010). Surgical staging is generally extrapolated from epithelial ovarian cancer, but lymphadenectomy is particularly important (Chap. 35). Of the malignant germ cell tumors, dysgerminoma has the highest rate of nodal metastases, approximately 25 to 30 percent (Kumar, 2008). Although staging deviations do not adversely affect survival, comprehensive staging allows a safe observation strategy for stage IA tumors (Billmire, 2004; Palenzuela, 2008). Preservation of the contralateral ovary leads to “recurrent” dysgerminoma in 5 to 10 percent of retained gonads during the next 2 years.

Question 91

Dysgerminomas have the best prognosis of all malignant ovarian germ cell tumor variants. Two thirds are stage I at diagnosis, and the 5-year disease-specific survival rate approximates

Answer 91

99 %
Even those with advanced disease have high survival rates following chemotherapy. For example, those with stage II-IV disease have a greater than 98-percent survival rate with platinum-based agents (Chan, 2008). a result carboplatin may be preferable to cisplatin in these patients due to equivalent outcomes with reduced long-term toxicity (Shah, 2018; Skalleberg, 2017).

excess-estrogen environment (type I endometrial cancer)
Polycystic ovarian syndrome Long-term, high-dose unopposed menopausal estrogens Early age of menarche Late age of natural menopause Infertility Nulliparity Menstrual irregularities North America or northern Europe residence Higher education or income level White race Older age Tamoxifen, hereditry (lynch syndrome), high cumulative doses DM, CHTN, or gallbladder disease Lower risk with Long-term COC use Cigarette smoking

Question 95

The cornerstone of treatment of endometrial cancer

Answer 95

hysterectomy with bilateral salpingo-oophorectomy (BSO) and surgical staging that includes lymph node assessment for most women. Of affected women, 67 percent will have stage I disease that is potentially curable by surgery alone, although high-risk stage I patients often receive adjuvant therapy (Siegd, 2019).

Question 96

the sixth leading cause of cancer deaths among women

Answer 96

Endometrial cancer

Question 97

Endometrial adenocarcinomas are categorized as

Answer 97

type I or type II based on histology.
Type I, that is, endometrioid type, makes up 80 to 90 percent of all cases (Felix, 2010).
The other 10 to 20 percent are type II cancers, namely, the non-endometrioid histologic types that include serous and clear cell adenocarcinomas and carcinosarcoma.

Question 98

Question 100

the most common extracolonic manifestation of Lynch syndrome (hereditary nonpolyposis colorectal cancer [HNPCC])

Answer 100

Endometrial cancer
Of all endometrial cancer cases, 2.3 percent are attributable to Lynch syndrome, and these cases develop more than 10 years earlier than sporadic endometrial cancer (Resnick, 2009).

Question 101

Lynch syndrome (hereditary nonpolyposis colorectal cancer [HNPCC]) mode of Inheritance

Answer 101

This autosomal-dominant syndrome results primarily from mutations in the mismatch repair genes MLH1, MSH2, MSH6, and PMS2
Gene mutation prevents repair of base mismatches, which are commonly produced during DNA replication. Inactivity of this DNA repair system leads to mutations that can promote carcinogenesis. Mutation carriers have a risk of developing endometrial cancer that ranges from 40 to 60 percent. Among affected women, endometrial cancer often develops at a young age, and the risk for this cancer actually exceeds that for colorectal cancer

Question 102

Tamoxifen causes a – to – fold higher risk of developing endometrial cancer by its modest “unopposed” estrogenic effect on the endometrium

Answer 102

Tamoxifen causes a two-to three fold higher risk of developing endometrial cancer by its modest “unopposed” estrogenic effect on the endometrium.
(cancer rates rise linearly with the duration and cumulative dose of tamoxifen therapy)
Accordingly, women taking tamoxifen are counseled regarding this endometrial risk and should report vaginal spotting, bleeding, or discharge. That said, unless a tamoxifen-treated patient has such symptoms, routine endometrial surveillance does not improve early detection rates (American College of Obstetricians and Gynecologists, 2019c}.

Question 103

combination oral contraceptive (COC) use for at least 1 year confers as much as a — to – percent reduced endometrial cancer risk. Risk reduction extends for 10 to 20 years.

Answer 103

combination oral contraceptive (COC) use for at least 1 year confers as much as a 30-to 50-percent reduced endometrial cancer risk. Risk reduction extends for 10 to 20 years.

Question 104

Endometrial hyperplasia is defined as

Answer 104

endometrial thickening with proliferation of irregularly sized and shaped glands and an increased gland-to-stroma ratio.
(In the absence of such thickening, lesions are best designated as disorderly proliferative mdometrium or focal glandular crowding)

Question 105

The classification system of endometrial hyperplasia used by the World Health Organization {WHO) and International Society of Gynecological Pathologists designates two different types with varying malignant potential

Answer 105

1) Hyperplasia without atypia is characterized by exaggerated endometrial gland proliferation and an increased gland-to-stroma ratio compared with normal proliferative endometrium, but without significant cytologic atypia.
2) Atypical endometrial hyperplasias are clearly associated with the subsequent development of adenocarcinoma
Although endometrial hyperplasias are formally classified in these two different groups, they tend to be morphologically heterogeneous, Endometrial intraepithelial neoplasia (EIN) is a term introduced to more accurately distinguish the two very different clinical categories of hyperplasia.

Question 106

Endometrial intraepithelial neoplasia (EIN) is a term introduced to more accurately distinguish the two very different clinical categories of hyperplasia. These are:

Answer 106

(1) nonnal polyclonal endometrium diffusely responding to an abnormal hormonal environment and
(2) intrinsically proliferative monoclonal lesions that arise focally and confer an devated risk of adenocarcinoma
The ElN classification system is a more accurate and reproducible way to predict progression to cancer and is recognized by the American College of Obstetricians and Gynecologisu and Society of Gynecologic Oncology (2017a). However, it is not been universally implemented

Question 107

Pipelle office endometrial biopsy (EMB) indications:

Answer 107

The American College of Obstetricians and Gynecologists (2016) recommends such a sample for women older than 45 years with AUB. EMB is also considered for those younger than 45 with chronic excess estrogen exposure (exogenous or endogenous), failed medical management, and persistent AUB.
All patients older than 35 years with AGC cervical cytology should undergo endometrial biopsy. Endometrial biopsy also is recommended for women of any age with AGC cytology and risk factors for endometrial cancer (eg, abnormal
bleeding, obesity, anovulation) or cytologic diagnosis of AGC, favor endometrial origin.

Question 108

Cut-off point for endometrial thickness that mandate endometrial sample in symptomatic postmenopausal women

Answer 108

For these women, endometrial stripe thickness measurements less or equal to 4 mm and associated with bleeding that is a.attributed to endomcttial atrophy (Amerian College of Obstmicians and Gynecologim, 2018b). Postmcnopausal women with a thicker endometrium warrant biopsy. Sonography may also identify abnormal echostructural changes in the endometrium. Cystic endometrial changes suggest polyps, homogeneously thickened endometrium may indicate hyperplasia, and a heterogeneous structural pattern is suspicious for malignancy. However, these sonographic findings show great overlap and cannot be used alone.

Question 109

Cut-off point for endometrial thickness that mandate endometrial sample in asymptomatic postmenopausal women

Answer 109

Endometrial thickness >4 mm may be identified in postmenopausal women undergoing sonographic evaluation for reasons unrelated to postmenopausal bleeding. The positive predictive value of an •abnormal” endometrial thickness in asymptomatic women would be expected to be low, because the disease prevalence in asymptomatic patients is low. It is therefore reasonable to use a higher threshold value for these patients. The Society of Obstetrics and Gynecology of Canada suggests 11 mm as the threshold in asymptomatic women (Wolfman, 2010).

Question 110

yolk sac tumor pathognomic histopathology feature

Answer 110

Schiller-Duval body (This structure consists of a central caplllary surrounded by tumor cells, present within a cystic space that may be lined by flat to cuboidal tumor cells)

Question 111

Features of yolk sac tumor age of population:

Answer 111

One third of individuals are premenarchal at the time of initial presentation. Involvement of both gonads is rare, and the other ovaty is usually involved with metastatic disease only when other metastases are found in the peritoneal cavity.

Question 112

In immature teratoma, survival is predicted most accurately by stage and by histologic grade of the tumor. How to counsel the patient ?

Answer 112

almost three quarters of immature teratomas are stage I at diagnosis and have a 5~year survival rate of 98 percent (Chan, 2008). Those with stage IA grade 1 immature teratomas have an excellent prognosis and do not require adjuvant chemotherapy (Bona,1994; Marina, 1999). Patients with stage II-IV disease have a 5-year survival rate ranging from 73 to 88 percent (Chan, 2008).

Question 113

the standard care of management for immature teratoma and other malignant germ cell tumors in reproductive-aged women

Answer 113

Unilateral salpingo-oophorectomy

Question 114

The most frequent site of dissemination of immature teratoma is

Answer 114

the peritoneum and much less commonly the retroperitoneal lymph nodes.

Question 115

The most common Malignant Transformation variant of Mature Cystic Teratomas

Answer 115

Squamous cell carcinoma is most common and is found in approximately 1 percent of mature cystic teratomas typically develop in postmenopausal women

Question 116

Steps of surgical staging of ovarian cancer:

Answer 116

• vertical abdominal incision is still traditionally recommended if an advanced ovarian malignancy is suspected.
• If present, ascites is evacuated and sent for cytologic evaluation. Otherwise, washings of the pelvis and paracolic gutters are collected for analysis prior to manipulation of the intraperitoneal contents.
• The entire peritoneal cavity is systematically inspected. The ovaries are assessed for size, tumor involvement, capsular rupture, external excrescences, and adherence to surrounding structures.
• Fertility-sparing USO is performed in all reproductive-aged women diagnosed with malignant ovarian germ cell tumors, as this conservative approach in general does not adversely affect survival
  who has completed childbearing and would derive little benefit from retaining an ovary, hysterectomy with bilateral salpingo-oophorectomy (BSO) is appropriate
• lymphadenectomy is most important for dysge.rminomas, whereas staging peritoneal and omental biopsies are particularly valuable for yolk sac tumors and immature teratomas
• Cytoreductive surgery is recommended for advanced-stage nondysgenninomatous malignant ovaiian germ cell tumors if it can be accomplished with minimal residual disease (Ovarian dysgerminomas are so chemosensitive they do not generally require aggressive attempts at debulking)

Question 117

Chemotherapy standard regimen for malignant germ cell ovarian tumors

Answer 117

The standard regimen is a 5-day course of bleomycin, etoposide, and cisplatin (BEP) given every 3 weeks (Gershenson, 1990; Williams, 1987). Modified 3-day BEP combinations also are safe and effective (Chen, 2014; Dimopoulos, 2004). Carboplatin and etoposide, given in three cycles, has shown promise as an alternative for selected patients (Williams, 2004). For women with incompletely resected disease, at least four courses ofBEP are usually recommended (Morgan, 2016).

Question 118

the preferred treatment for recurrent ovarian germ cell tumors in women initially managed with surgery alone.

Answer 118

At least four courses of BEP chemotherapy, Patients who achieved a sustained clinical remission of greater than 6 months after completing BEP or another platinum-based chemotherapy regimen may be treated again with BEP. Because their tumors are generally more responsive, these “platinum-sensitive” patients have a much better prognosis.
However, women who do not achieve remission with BEP chemotherapy or relapse within a few months (fewer than 6) are considered “platinum-resistant,” and treatment options are limited. Chemorefractory cases with dysgerminoma or immature teratoma appear to have a better outcome than other subtypes, and surgical salvage aimed at achieving no residual disease may benefit some patients (Li, 2007). Other palliative options for this group include vincristine, dactinomycin, and cyclophosphamide (VAC) or paclitaxel (Morgan, 2016).

Question 119

Mature cystic teratomas (dermoid cysts) make up —- of tumors resected during pregnancy

Answer 119

Mature cystic teratomas (dermoid cysts) make up one third of tumors resected during pregnancy

Question 120

Management of germ cells tumor in pregnancy

Answer 120

Surgical staging as non pregnant
for patients with nondysgerminomatous tumors (mainly yolk sac tumors and immature teratomas) and those with incompletely resected disease, chemotherapy during pregnancy is strongly considered.

Question 121

Age of population of sex cord stromal ovarian tumors

Answer 121

ovarian SCST s typically affect women of all ages. This range contains a unique bimodal distribution that reflects inherent tumor heterogeneity. For example, juvenile granulosa cell tumors, Sertoli-Leydig cell tumors, and sclerosing stromal tumors are found predominantly in prepubertal girls and women within the first three decades of life (Schneider, 2005). Adult granulosa cell tumors commonly develop in older women, at an average age in the mid-50s (van Meurs, 2013).

Question 122

Genetic etiology behind SCST (sex cord stromal ovarian tumors)

Answer 122

The etiology of SCSTs is largely unknown. However, a single, recurrent FOXL2 gene mutation is present in vinually all adult-type granulosa cell tumors (Schrader, 2009; Shah, 2009). Also, women with a germline DICER1 mutation are predisposed to developing SCSTs (Heravi-Moussavi, 2012)

Question 123

ovarian SCSTs develop in association with several defined hereditary disorders at a frequency that exceeds mere chance. These include

Answer 123

Ollier disease, which is characterized by multiple benign but disfiguring cartilaginous neoplasms, and Peutz-Jeghers syndrome, characterized by intestinal hamartomatous polyps (Stevens, 2005).

Question 124

serum testosterone levels> ISO ng/dL or dehydroepiandrosterone sulfate (DHEAS) levels >8000 µg/L strongly suggest the possibility of

Answer 124

an androgen-secreting tumor

Question 125

Modified WHO Classification of Ovarian Sex Cord-Stromal Tumors

Answer 125

*Pure stromal tumors: Fibroma/fibrosarcoma Thecoma Sclerosing stromal tumor Leydig cell tumor Steroid cell tumor

granulosa cell tumors

Question 129

the most definitive treatment of endometrial hyperplasia

Answer 129

Hysterectomy

Question 130

Management of Premenopausal women with nonatypical endometrial hyperplasia

Answer 130

a 3-to 6-month course of low-dose progestin therapy. Cyclic medroxyprogesterone acetate (MPA) (Provera) given orally for 12 to 14 days each month at a dose of 10 to 20 mg daily is commonly used. Continuous daily dosing with MPA 10 mg is suitable and may be more effective than cyclic administration in reversing hyperplastic changes. Another frequently used option is COC pills for those without contraindications. The levonorgestrel-releasing IUD also is effective (Gallos, 2010; 0rbo, 2014; Scarselli, 2011).

Question 131

Managment of Postmenopausal women with nonatypical endometrial hyperplasia

Answer 131

low-dose oral cyclic MPA or a continuous 10-mg daily regimen, Importantly, in older women, providers should be confident that the sample obtained is adequate to exclude cytologic atypia. D & C may be indicated at times, especially if the tissue from Pipelle sampling is scant or if recurrent bleeding is noted. Affected postmenopausal patients who have a contraindication to progestin therapy or who cannot tolerate the therapy can be expectantly managed. Complex hyperplasia without atypia is usually treated chronically with progestins. Office endometrial biopsy is recommended every 3 to 6 months until lesion resolution is achieved.

Question 132

In cases of endometrial hyperplasia without atypia, the risk of progression to endometrial cancer is

Answer 132

only 1 to 3 percent. The overall clinical and pathologic regression rates to progestin therapy range from 70 to 80 percent for nonatypical endometrial hyperplasia (Rattanachaiyanont, 2005; Reed, 2009).

Question 133

Patients on progestins with persistent endometrial hyperplasia without atypia on repeated biopsy may be switched to

Answer 133

higher-dose regimen such as MPA 40 to 100 mg orally daily. Also, megestrol acetate (Megace), 160 mg daily or 80 mg twice daily, is suitable. It can be increased even up to 160 mg twice daily if no regression is initially achieved. Again, a clinician must confirm that hormonal ablation has occurred by resampling the endometrium after a suitable therapeutic interval, usually 3 to 6 months. Hysterectomy may also be considered for lesions that are refractory to medical management.

Question 134

TLH Vs. LAVH

Answer 134

LAVH is preferred in patients with a mass involving the lower segment or a relatively large uterus. (A uterus >12 weeks gestation in size was the only factor considered for LAVH)

Question 135

the risk of progression to cancer over time with Atypical endometrial hyperplasia

Answer 135

approximates 29 percent.

Question 136

the preferred treatment for women with atypical endometrial hyperplasia

Answer 136

Hysterectomy

Question 137

Management Premenopausal women with Atypical endometrial hyperplasia who strongly wish to preserve fertil~ ity can be treated with progestins

Answer 137

High-dose progestin therapy, megestrol acetate 80 mg orally twice daily, is an option for motivated patients who will be compliant with surveillance (Randall, 1997). The IUD that releases 20 µg of intrauterine levonorgestrel daily (Mirena, Llletta) also is suitable (0rbo, 2014).

Question 138

How to check for Resolution of atypical endometrial hyperplasia in pt using hormonal ablation

Answer 138

must be confirmed by serial endometrial biopsies every 3 months until response is documented.

Question 139

ENDOMETRIAL CANCER TYPES

Answer 139

• type I endometrioid adenocarcinomas constitute most cases. They are estrogen-dependent, low grade, and derived from atypical endometrial hyperplasia.
• type II cancers are serous, carcinosarcoma, or clear cell histology; have no precursor lesion; and portend a more aggressive clinical course.

Question 140

routine screening of hyperplasia or endometrial cancer is not advocated. Instead, at the onset of menopause, women are counseled on the risks and symptoms of endometrial cancer and strongly encouraged to report unexpected bleeding or spotting to their provider. One screening exception is the woman with Lynch syndrome. Which is

Answer 140

For these individuals, EMB is recommended every 1 to 2 years beginning at age 30 to 35 years (American College of Obstetricians and Gynecologists, 2019a; Smith, 2019).

Question 141

Lynch Syndrome Genetic Screening Recommendations

Answer 141

Patients with endometrial or colorectal cancer and tumor evidence of:
Microsatellite instability or DNA mismatch repair protein loss
First-degree relative with endometrial or colorectal cancer who was diagnosed: Before age 60 years or Is at risk for Lynch syndrome based on personal and medical history First-or second-degree relative with a known DNA mismatch repair gene mutation

Question 142

Lynch syndrome screening is performed by

Answer 142

histochemistry staining of the tumor to search for the four most important Lynch syndrome proteins expressed by the mismatch repair (MMR) genes MLHl, MSH2, MSH6, and PMS2.For patients who have negative screening results but who are still suspected of having Lynch syndrome based on family history, further testing for microsatellite instability may be performed. The combination of intact protein expression and lack of microsatellite instability predicts a very low risk of Lynch syndrome.

Question 143

women with Lynch syndrome have such a high lifetime risk of developing endometrial cancer account to – to – %

Answer 143

(40 to 60 percent)

Question 144

Because women with Lynch syndrome have such a high lifetime risk of developing endometrial cancer (40 to 60 percent), what prophylactic step can be taken ?

Answer 144

prophylactic hysterectomy is recommended once affected women reach the early to mid 40s and have completed childbearing.
BSO also is performed due to the 9-to 12-percent lifetime risk of ovarian cancer. Prior to hysterectomy, colon cancer screening with colonoscopy should be up to date (American College of Obstetrician and Gynecologists, 2019a).

Question 145

Seventy percent of ovarian SCSTs are

Answer 145

granulosa cell tumors (the adult form, which comprises 95 percent of cases, and the juvenile type, accounting for 5 percent)

Question 146

In this tumor Cells are typically crowded and contain scant pale cytoplasm. Their elongated nuclei may have a longtudinal fold or groove that gives them a coffee bean appearance. Call-Exner bodies are ldentified by their rosette appearance.

Answer 146

Granulosa cell tumor

Question 147

Related to this oestrogen excess, coexisting pathology such as endometrial hyperplasia or adenocarcinoma has been found in – to – percent of patient with adult granulosa cell tumor

Answer 147

Related to this esttogen excess, coexisting pathology such as endometrial hyperplasia or adenocarcinoma has been found in 25 to 30 percent of patienu with adult granulosa cell tumor

Question 148

Adult granulosa cell tumors features are

Answer 148

low-grade malignancies that typically demonstrate indolent growth. Ninety-five percent arc unilateral, and 70 to 90 percent are stage I at diagnosis The 5-year survival for patients with stage I disease is 90 to 95 percent (Colombo, 2007; Zhang, 2007). However, 15 to 25 percent of stage I tumors will eventually relapse. The median time to recurrence is 5 to 6 years but may be several decades (Abu-Rustum, 2006; East, 2005)

Question 149

Poor prognostic factors of granulosa cell tumors are

Answer 149

advanced stage, large tumor size, and residual disease (Seagle, 2017). Patients with stage II-IV tumors have a 5-year survival we of 50 to 80 percent (Seagle, 2017). Cellular atypia and mitotic count may help in determining the prognosis but are difficult to reproducibly quantify (Miller, 2001).

Question 150

the fifth leading cause of cancer-related death

Answer 150

Answer 160

100%

Question 161

Histologically, LMP tumors are distinguished from benign cysts by having at least two of the following features:

Answer 161

nuclear atypia, epithelial stratification, microscopic papillary projections, cellular pleomorphism, or mitotic activity

Question 162

Unlike invasive carcinomas, Low Malignant Potential tumors lack

Answer 162

stromal invasion. However, up to 10 percent of LMP turners will exhibit areas of microinvasion, defined as foci measuring <3 mm in diameter and forming <5 percent of the tumor

Question 163

The prognosis is excellent for patients with ovarian LMP tumors. Five-year survival rates range from %

Answer 163

96 to 99 percent for stages I-III, whereas it reaches 77 percent for stage IV disease (Trimble, 2002). Overall, more than 80 percent have stage I disease. Fertility-sparing surgery is associated with up to a 15-pcrcent risk of rdapsc, usually in the contralatcral ovary, but remains highly curable by rcoperation and resection. (Park, 2009; Rao, 2005).

Question 164

What are the endometriosis–associated rumors ?

Answer 164

Endometrioid
Clear cell
Seromucinous

Question 165

The serum CA125 level is integral to epithelial ovarian cancer management. In 90 percent of women presenting with malignant nonmucinous tumors. CA125 Ievels are elevated.

Answer 165

to bear in mind during adnexal mass evaluation. Half of stage I ovarian cancers will have a normal CA125 measurement (false negative). Also. an elevated value (false positive) may be associated with various common benign indications such as pelvic inflammatory disease, endometriosis, leiomyoma, pregnancy. and even menstruation. Thus. in postmenopausal women with a pelvic mass. a CA125 measurement may better predict a higher likdihood of malignancy

Question 166

World Health Organization Histological Classification of Ovarian Carcinoma

Small cell carcinoma

Question 167

During frozen section analysis, ———– are essentially pathognomonic of an ovarian-type serous carcinoma.

Answer 167

During frozen section analysis, psammoma bodies are essentially pathognomonic of an ovarian-type serous carcinoma.

Question 168

Mucinous adenocarcinomas compose – to – percent of true epithelial ovarian cancers.

Answer 168

Mucinous adenocarcinomas compose 5 to 10 percent of true epithelial ovarian cancers.

Question 169

Clear Cell Adenocarcinoma Comprising – to – percent of epithelial ovarian cancers

Answer 169

Clear Cell Adenocarcinoma Comprising 5 to 10 percent of epithelial ovarian cancers

Question 170

———- adenocarcinomas are most frequently associated with pelvic endometriosis.

Answer 170

clear cell adenocarcinomas are most frequently associated with pelvic end.ometriosis.

Question 171

Microscopically, both clear and “hobnail” cells are characteristic to

Answer 171

Clear cell carcinoma

Question 172

Transitional cell carcinoma accounts for fewer than – percent of ovarian cancers.

Answer 172

Transitional cell carcinoma accounts for fewer than 5 percent of ovarian cancers.

Question 173

Transitional cell carcinoma prognosis

Answer 173

Microscopically, these tumors resemble a primary bladder carcinoma, often with squamous differentiation, but have an immunoreactive pattem consistent with. an ovarian origin (Lee, 2003). Thus, transitional cell carcinoma is considered a high-grade form of serous carcinoma but carries a better prognosis (Guseh, 2014). The rare malignant Brmnn tumor characteristically lw transitional cell carcinoma coupled with foci of benign or borderline Brenner features. 1b.e&e twnors classically have a dense, abundant fibrous stroma with. embedded nests of transitional epith.dium. They carry a better prognosis than pwe transitional cell carcinomas.

Question 174

Small cell carcinoma prognosis

Answer 174

rare, extremely malignant,Recent data suggest these highly lethal tumors arise via a specific muta· tion in the SMARCA4 gene Odinic, 2014).In general, patients with small cell carcinoma die within 2 years from rapid disease progression.

Question 175

Small cell carcinoma types

Answer 175

• hyperkalcemic type, which typically develops in young women. Nearly all tumors arc unilateral, and two thirds are associated with elevated serum caJ. cium levels that resolve postoperatively (Young, 1994).
• The pulmonary type resembles oat cell carcinoma of the lung and develops in older women. Half of these women have bilateral ovarian disease (Eichhorn, 1992).

Question 176

Small cell carcinoma types

Answer 176

• hyperkalcemic type, which typically develops in young women. Nearly all tumors arc unilateral, and two thirds are associated with elevated serum caJ. cium levels that resolve postoperatively (Young, 1994).
• The pulmonary type resembles oat cell carcinoma of the lung and develops in older women. Half of these women have bilateral ovarian disease (Eichhorn, 1992).

Question 177

Up to – percent of”typical” epithelial ovarian cancers are actually primary peritoneal carcinomas that develop de novo from the lining of the pelvis and abdomen.

Answer 177

Up to 15 percent of”typical” epithelial ovarian cancers are actually primary peritoneal carcinomas that develop de novo from the lining of the pelvis and abdomen.

Question 178

Criteria for Diagnosing Primary Peritoneal Carcinoma When Ovaries Are Present

Answer 178

• Both ovaries must be normal in size or enlarged by a benign process
• The involvement in the extraovarian sites must be greater than the involvement on the surface of either ovary - The ovarian tumor involvement must be either nonexistent, confined to the ovarian surface epithelium without stromal invasion, or involving the cortical stroma with tumor size less than 5 x 5 mm.
  لكن ولله الحمد
  In general, the stag· ing, treauncnt, and prognosis of primary peritoneal carcinoma are the same as for epithelial ovarian cancc:r (Mok, 2003). The differential diagnosis mainly includes malignant mesothelioma. :)

Question 179

metastatic mucinous/signet ring cell adenocarcinoma

Answer 179

Krukenburge tumor Malignant rumors that metastasize to the ovary are almost invariably bilateral that typically originates from primary tumors of the intestinal tract, characteristically the stomach. Ovarian metastases often represent a late disseminated stage of the disease in which other hematogenous metastases also are found (Prat, 2003).

Question 180

Management of Early-Stage epithelial Ovarian Cancer

Answer 180

• Surgical Staging
• Fertility-Sparing Management if disease appears confined to one ovary. Although many patients will be “up-staged” as a result of the operative findings, those with surgical stage I disease have an excellent long-term survival following unilateral adnexectomy (Armstrong, 2019).
• Postsurgical Management In women with stage lA or IB, grade 1 or 2 epithelial ovarian carcinoma, observation without further treatment following surgery is appropriate (Armstrong, 2019).

Question 181

Post surgical management of epithelial ovarian cancer

Answer 181

Postsurgical Management In women with stage lA or IB, grade 1 or 2 epithelial ovarian carcinoma, observation without further treatment following surgery is appropriate (Armstrong, 2019). However, one third of patients who appear to have disease confined to the ovary will be up-staged by surgical staging and require postoperative chemotherapy. Women with stage lA or IB, grade 3 epithelial ovarian cancer and all stage IC and II tumors are treated with platinum-based chemotherapy (Armstrong, 2019). In a Phase III Gynecologic Oncology Group (GOG) trial (protocol #157), women with earlystage disease were randomly assigned to either three or six cycles of carboplatin (Paraplatin) and paclitaxel (T axol). Overall, three cycles resulted in a relapse rate comparable to that fur six cycles but caused less toxicity (Bell, 2006). However, in a subanalysis of patients in this study who had serous tumors, treatment with six cycles decreased the relapse risk (Chan, 2010a). Despite chemotherapy, more than 20 percent of women with early-stage disease develop recurrences within 5 years.

Question 182

Surveillance after complete treatment of early stage ovarian cancer

Answer 182

After treatment completion, women with early-stage ovarian cancer may be followed every 2 to 4 months for the first 2 years, twice yearly fur an additional 3 years, and then annually. At each visit, complete physical and pelvic examinations are performed. In addition, a serum CA125 level may be indicated if it was initially elevated (Armstrong, 2019). However, one multi-institutional trial evaluated the utility of CA125 levels for ovarian cancer monitoring after primary therapy completion. Women with relapsed ovarian cancer did not live longer by starting chemotherapy earlier based on a rising CA125 level compared with delaying treatment until symptoms developed. The group monitored with CA125 tests received 5 more months of chemotherapy overall, whereas women who were diagnosed and treated later for clinically evident recurrence had higher quality-of-life measures (Rustin, 2010). Whether suspected by examination, CA125 level elevation, or new symptoms, recurrent disease must be confirmed with the aid of imaging. Of modalities, CT is initially most helpful to identify intraperitoneal disease.

Question 183

Candidates of neoadjuvant chemotherapy

Answer 183

unresectable disease. Other patients may be too medically compromised, may not have received initial care by a gynecologic oncologist, or may have large-volume “suboptimal” residual disease despite attempted debulking. In such circumstances, three to four courses of chemotherapy are used to shrink disease before attempting an “interval” cytoreductive surgery.

Question 184

Adjuvant chemotherapy used for epithelial ovarian ca

Answer 184

the most widely used intravenous (IV) regimen in the United States is six courses of carboplatin and paclitaxel. If additional cycles are required to achieve clinical remission, this suggests relative tumor chemoresistance and usually leads to an earlier relapse. In Europe, single-agent carboplatin often is used. This preference is based on two large Phase III trials of the International Collaborative Ovarian Neoplasm (ICON) Group

Question 185

maintenance chemotherapy in Management of Patients in Remission stage of advanced ovarian cancer

Answer 185

• monthly paclitaxel was disappointing and caused significant neuropathy(Markman, 2003, 2009). In a later Phase III trial of 1157 patients, neither lower-dose paclitaxd nor CT-2103 (paclitaxd poliglumex) reduced the death rate compared with no maintenance therapy.
  -Bevacizumab, an antiangiogenic agent, also has been studied as maintenance therapy in several Phase III trials. In GOG protocol #218 and the Gynecologic InterGroup Trial (ICON7) studies noted earlier (p. 749), bevacizumab was combined with paclitaxel and carboplatin and then continued alone for a year of maintenance therapy. This regimen demonstrated only a 2-to 4-month prolongation of progression-free survival and no overall survival benefit (Tewari, 2019)
• Pazopanib, an oral multikinase inhibitor of the vascular endothelial growth factor (VEGF} receptor, also shows some promise as maintenance therapy. In a Phase III trial, patients receiving pazopanib had a 5.6-month improvement in progression-free survival compared with placebo. Still, it was associated with significant toxicity and lack of overall survival benefit (duBois, 2014).

Question 186

The overall 5-year survival rate of all stages of epithelial ovarian cancer approximates — percent, uterine __ percent , cervical cancer (__ percent).

Answer 186

The overall 5-year survival rate of all stages of epithelial ovarian cancer approximates 45 percent, far lower than uterine (84 percent} or cervical cancer (73 percent).

Question 187

Most Important Favorable Prognostic Factors for Ovarian Cancer

Answer 187

No ascites
Younger age
Early-stage disease
Well-differentiated tumor
Otherwise good health status
Histologic type other than mucinous or clear cell
Small disease Volume prior to surgical debulking
Small residual tumor following primary cytoreductive surgery

Question 188

Management of Recurrent Ovarian Cancer

Answer 188

Tamoxifen may be administered when only “biochemical” evidence - means elevation in CA-125 only- indicates disease progression. It has some activity in ueating recurrent disease, and its toxicity is minimal (Hurteau, 2010).

Question 189

usually the first sign of ovarian cancer relapse

Answer 189

Gradual elevation of the CA125 level

Question 190

Management of Those who relapse within 6 months of completing chemotherapy have “platinum-resistant” ovarian cancer

Answer 190

should be encouraged whenever possible, response rates typically range from 5 to 15 percent using nonplatinum FDA-approved conventional cytotoxic drugs such as paclitaxel, pegylated liposomal doxorubicin (Doxil), docetaxel (Taxotere), topotecan (Hycamtin), or gemcitabine (Gemzar). Recendy, bevacizumab in combination with weekly paclitaxel, doxorubicin, or topotecan was shown to provide a 27-percent response rate. This was more than double the rate with single-agent chemotherapy alone in patients with platinum-resistant disease (Pujade-Lauraine, 2014).

Question 191

the best candidates for secondary cytoreductive surgery have:

Answer 191

(1) platinum-sensitive disease,
(2) a prior long disease-free interval,
(3) a solitary-site recurrence, and
(4) no ascites (Chi, 2006; Armstrong, 2019).

Question 192

Patients with a germline BRCAI or BRCA2 gene mutation who develop resistance to platinum may benefit from

Answer 192

targeted therapy with olaparib, niraparib (Zejula), or rucaparib (Rubraca). All three PARP inhibitors are now FDA-approved for this indication

Question 193

Worldwide, cervical cancer is common, and it ranks —- among all malignancies for women

Answer 193

Serotype 18 was associated with – percent of invasive disease cases ( Guan, 2012).

Answer 195

63 percent of invasive cervical cancer cases were attributable to HPV serotype 16. Serotype 18 was associated with 16 percent of invasive disease cases ( Guan, 2012).

Question 196

HPV 16 is more commonly associated with —— carcinoma of the cervix, whereas HPV 18 is a risk factor for —– carcinoma (Bulk, 2006).

Answer 196

HPV 16 is more commonly associated with squamous cdl carcinoma of the cervix, whereas HPV 18 is a risk factor for cervical adenocarcinoma (Bulk, 2006).

Question 197

Among HPV-infected women, current and former smokers have a —to —fold greater incidence of highgrade squamous intraepithdiallesion (HSIL) or invasive cancer.

Answer 197

Among HPV-infected women, current and former smokers have a two-to threefold greater incidence of highgrade squamous intraepithdiallesion (HSIL) or invasive cancer.

Question 198

women with seven prior full-term pregnancies have an approximately —fold risk of having HPV and cervical cancer, and those with one or two have a –fold risk compared with nulliparas (Munoz, 2002)

Answer 198

women with seven prior full-term pregnancies have an approximately fourfold risk, and those with one or two have a twofold risk compared with nulliparas (Munoz, 2002)

Question 199

COCP and cervical cancer

Answer 199

Long-term combination oral contraceptive (COC) use is another factor. In women who are positive for cervical HPV DNA and who use COCs, cervical carcinoma rates rise by up to fourfold compared with women who are HPV -positive and never users (Moreno, 2002). Additionally, current COC users and women who are within 9 years of use have a significandy higher risk of developing both squamous cell and adenocarcinoma of the cervix (International Collaboration of Epidemiological Studies of Cervical Cancer, 2006). Encouragingly, the relative risk to COC users appears to decline after cessation. Data from 24 epidemiologic studies showed that by 10 or more years following COC cessation, cervical cancer risk returns to that of never users (International Collaboration of Epidemiological Studies of Cervical Cancer, 2007).

Question 200

cervical lymphatic drainage

Answer 200

From the parametrial and paracervical nodes, lymph subsequently flows into the obturator lymph nodes and into the internal, external, common iliac lymph nodes, and ultimately the paraaortic lymph nodes. Accordingly, pelvic and paraaortic lymph nodes are also traditionally removed concurrently with radical hysterectomy. In contrast, lymphatic channels from the posterior cervix course through the rectal pillars and the uterosacral ligaments to the rectal lymph nodes. These nodes also are encountered and are removed during the extended resection of the uterosacral ligaments that is characteristic of radical hysterectomy.

Question 201

Management of woman presents with uncontrolled hemorrhage from cervical tumor bed (spontaneously or after punch biopsy)

Answer 201

bleeding can often be controlled with a combination of Monsel paste (ferric subsulfate) and vaginal packing. Topical acetone can also be used to obtain hemostasis, especially in cases refractory to Monsel paste (Patsner, 1993). Burning from acetone makes it a less desirable choice than Monsel paste. With vaginal packing, the patient ideally remains at bed rest, and a Foley catheter is concurrently inserted to drain the bladder. The pack may interfere with normal voiding, and the catheter also allows for accurate monitoring of urine output during volume resuscitation. If bleeding continues, emergent radiation can be delivered. Alternatively, internal iliac artery embolization or ligation can be performed in cases of refractory hemorrhage. However, caution is used for these latter two options, as tumor oxygenation is impaired if the blood supply is occluded. Radiation therapy is a primary component of advanced-stage cancer, radiation’s effects are diminished in low-oxygen environments. This can translate into worsening diseasespecific survival rates (Kapp, 2005). In those with significant bleeding, hemodynamic support of the patient

Question 202

cervical cancer may mirror the appearance of ( ddx of cervical ca)

Answer 202

cervical leiomyoma, cervical polyp, vaginitis, cervical eversion, cervicitis, threatened abortion, placenta previa, cervical pregnancy, condyloma acuminata, herpetic ulcer, chancre, or a prolapsing uterine leiomyoma, polyp, or sarcoma.

Question 203

Pap testing has a sensitivity for detecting high-grade lesions on any given single test about – to – %

Answer 203

53-to 80-percent

Question 204

What is the sensitivity of pap smear in women who have stage I cervical cancer of single cytologic smears obtained are read as positive for cancer?

Answer 204

only 30 to 50 percent
Hence, Pap testing alone for evaluation of a suspicious lesion is discouraged. Instead, these lesions arc directly biopsied with TUchler biopsy forceps or a Kevorkian

Question 205

What is the FDG-PET ?

Answer 205

a radiolabeled analogue of glucose, fluorodeoxyglucose (FDG), is injected intravenously and is taken up by metabolically active cells such as rumor cells in PET scan.
Important note: PET is insensitive for lymphatic metastasis <5 mm. Moreover, its role in early-stage smaller, resectable rumors is limited (Sironi, 2006; Wright, 2005)

Question 206

Cervical Cancer Survival Rates According to Stage Stage 5-Year Survival

Answer 206

lA 100%
IB 88%
IIA 68%
lIB 44%
Ill 18-39%
IVA 18-34%

Question 207

EARLY-STAGE PRIMARY DISEASE TREATMENT of Stage lA ( microinvasive cervical cancer )< invasion depth to <5 mm

Answer 207

Stage IA1 These microinvasive tumors invade <3 mm and are associated with low risk of spread into the parametrial or uterosacral nodes, these lesions may be effectively treated with cervical conization alone.
However, a total extrafascial hysterectomy (type I hysterectomy) is preferred for women who have completed childbearing.

Question 208

Squamous cervical cancers with stromal invasion < 1 mm have a – percent risk of nodal metastasis, and those with 1 to 3 mm of stromal invasion carry a –percent risk.

Answer 208

1% , 1.5 %

Question 209

In stage IAI microinvasive cancers, the presence of LVSI increases the risk of lymph node metastasis and cancer recurrence to approximately – percent. Suggested treatment ?

Answer 209

In stage IAI microinvasive cancers, the presence of LVSI increases the risk of lymph node metastasis and cancer recurrence to approximately 5 percent. these cases are managed with modified radical hysterectomy (type II hysterectomy) and pelvic lymphadenectomy. Radical trachelectomy with pelvic lymph node dissection can be considered in those patients desiring fertility preservation (Olawaiye, 2009).

Question 210

General Treatment for Primary Invasive Cervical Carcinoma for stage IA2 (These microinvasive cervical lesions have stromal invasion that measures 2=3 mm to <5 mm. These cancers have a 7-percent risk of lymph node metastasis and carry a >4-percent risk of disease recurrence)

Answer 210

Radical hysterectomy+ PLND (consider SNLB) or Radical trachelectomy+ PLND (consider SNLB) for selected patients desiring fertility

Question 211

patient may be considered for pelvic exenteration if the triad of (1)(2)(3) is absent

Answer 211

(1) lower extremity edema,
(2) back pain,
(3) hydronephrosis
If present, these suggest disease extension to the pelvic sidewalls, which would contraindicate surgery.
In addition, regional and distant metastasis should be excluded by both physical c:xamination and radiologic imaging, which typically is a PET /CT scan.

Question 212

What is the most common type of Borderline tumor

Answer 212

Serous 50%
Mucinous 30%

Question 213

Factors associated with para-aortic lymph node dissemination include

Answer 213

advanced stage, high histological grade, deep myometrial invasion, cervical involvement, lymphovascular space involvement, and the presence of pelvic lymph node metastases.

Question 214

Mode of delivery of pregnant lady with micro invasive squamous cell cervical carcinoma found during conization that measures <3 mm and contains no LVSI (stage IAl)

Answer 214

may deliver vaginally and be reevaluated 6 weeks postpartum. Moreover, for those with stage IA or IB disease, studies find no greater maternal risk if treatment is intentionally ddayed to optimize fetal maturity regardless of the trimester in which the cancer was diagnosed. Given the outcomes, a planned treatment dday is generally acceptable for women who are 20 or more weeks’ gestational age at diagnosis with stage I disease and who desire to continue their pregnancy.

Question 215

Risks factors of vulvar cancer

Answer 215

Women who are infected with human papi/Jomatlirus (HPV) have a greater risk of vulvar cancer. Specifically, 50 to 75 percent of invasive vulvar cancers are associated with highrisk HPV serotypes (Gargano, 2012). Strong correlations also can be seen between high-risk HPV infection and preinvasive TABLE 31-1. Vulvar Cancer Histologic Subtypes Vulvar c:ardnomas Squamous cell carcinoma Adenocarcinoma Carcinoma of Bartholin gland Adenocarcinoma Squamous carcinoma Transitional cell Vulva Paget disease Merkel cell tumors Verrucous carcinoma Basal cell carcinoma Vulvar malignant melanoma Vulvar sarcoma Leiomyosarcoma Malignant fibrous histiocytoma Epithelial sarcoma Malignant rhabdoid tumor Metastatic cancers to vulva Yolk sac tumors lesions of the vulva (Gargano, 2012). HPV becomes a stronger contributor when combined with other cofactor& such as smoking or herpes simplex virus (HSV) infection (Madele.ine, 1997). Women who have smoked and have a history ofHPV genital warts have a 35-rold greater risk fOr developing vulvar cancer compared with women without these predispositions (Brinton, 1990; Kirschner, 1995).

Question 216

VIN is categorized as

Answer 216

1) Usual type VIN is associated with highrisk HPV infection and develops usually in young women.
2) the differentiated type VIN occurs in postmenopausal women with chronic skin conditions such as lichen sclerosis (Reyes, 20 14). Of these two, differentiated type VIN has a significantly stronger association with squamous cell carcinoma compared with usual type VIN (Eva, 2009).

Question 217

The nonavalent vaccine (Gardasil 9) is effective against which HPV sero-types

Answer 217

high-risk HPV scrotypes 16 and 18 (Huh, 2017).

Question 218

Overall survival rates of women with squamous cell carcinoma of the vulva are relarivdy good and approximate

Answer 218

65 percent (Razzagh.i, 2018).

Question 219

SEER (2018) data from 2008 to 2014 show that anticipated a 5-year survival rate for :
- local disease (stage I and II)
- higher stages are poorer, can be expected for regional (stage III and IV A) disease
- for stage IVB.

Answer 219

• rate 86 percent for local disease (stage I and II)
• rate of 54 percent for stage III and IV A
• rate of 16 percent for stage IVB.

Question 220

Apart from FIGO stage. other important prognostic factors of vulvar cancers(any any cancer) include

Answer 220

lymph node metastasis, lesion size, depth of invasion, resected-margin status, and lymphatic vascular space involvement.

Question 221

Depth of tumor invasion is another prognostic element of vulvar cancer This depth is measured from

Answer 221

from the epidermis basement membrane to the deepest point of invasion into the dermis and subcutaneous layer (Kurman, 2014). Tumors with a depth of invasion < 1 mm carry little or no risk of inguinal lymph node metastasis. However, depth of invasion positively correlates with increased nodal metastasis.

Question 222

the single most important vulvar cancer predictor

Answer 222

Lymph node metastasis, since inguinal node mewtasis reduces long-term sutvival rates by 50 percent (Farlas.-Eisner, 1994

Question 223

In vulvar cancer Surgical margins that are tumor-free lower local tumor recurrence rates. Thus, at a minimum

Answer 223

a 2-cm tumor-free margin is desired. More specifically, two large retrospective series demonstrated that a tumor-free surgical margin > or = 8 mm at final pathologic analysis yielded a high rate of local controL In contrast, if tumor was found within this 8-mm margin, the recurrence rate was 23 to 48 percent (Chan, 2007; Heaps, 1990)

Question 224

lnguinofemoral Lymphadenectomy is recommended for all vulvar squamous carcinomas that ( who are the candidates?)

Answer 224

invade deeper than 1 mm on initial biopsy or that have a tumor diameter > 2 cm regardless of invasion depth (stages IB- IV A). To maximize metastatic disease detection and staging accuracy, surgical evaluation of the inguinal nodes is recommended.

Question 225

One trial by the GOG reported the sensitivity of selective lymph node biopsy (SLNB) exceeded – percent, and the false negative predictive value was – percent for tumors measuring < 4 cm in diameter (Frurnovitz, 2005).

Answer 225

exceeded 90 percent, and the false negative predictive value was 2 percent for tumors measuring < 4 cm in diameter (Frurnovitz, 2005).

Question 226

In stage IV poorly resectable,. locally advanced vulvar cancers can be effectively treated with

Answer 226

neoadjuvant chemoradiation to minimize the surgical resection required. Two GOG studies GOG have demonstrated the feasibility of this approach using cisplatin regimens (Moore,. 1998, 2012).

Question 227

SURVEILLANCE After completing primary treatment of vulvar cancer

Answer 227

all patients receive thorough physical examination that includes inguinal lymph node palpation and pelvic examination every 3 months for the first 2 to 3 years. Surveillance examinations are then scheduled every 6 months to complete a total of 5 years. Thereafter, disease-free women may be seen annually (Salani, 20 17). Biopsies are performed if concerning areas are noted. Radiologic imaging and targeted biopsies to diagnose possible tumor recurrence are completed as indicated.

Question 228

VERRUCOUS CARCINOMA rare variant of vulvar squamous cell carcinoma treatment

Answer 228

Surgery is preferred, and most tumors are excised by wide local excision that ensures a 1-cm surrounding margin. Inadequate margins risk local recurrence. Verrucous carcinomas are resistant to radiotherapy and if exposed may undergo anaplastic transformation to become more aggressive and invasive. Enlarged groin lymph nodes are evaluated preoperatively by FNA because they usually are inflammatory.

Question 229

Ddx of vulvar melanoma

Answer 229

Benign conditions like lentigo simplex, vulvar melanosis, acanthosis nigricans, seborrheic keratosis, and nevi.
And malignant lesions like pigmented vulvar neoplasia may be VIN, squamous cell carcinoma, or Paget disease.

Question 230

Treatment of melanoma

Answer 230

Vulvar melanoma has limited response to both chemotherapy and radiotherapy. Thus, excision is the single best definitive therapy (Conservative surgery, such as wide local acis.ion or a radical partial wlvectomy).

Question 231

for treatment of metastatic or unresectable melanoma

Answer 231

• Vemurafenib (Zelboraf), a BRAF inhibitor, was approved by the Food and Drug Administration (FDA} for that exhibits the BRAF mutation (Robert, 2011).
• Imatinib (Gleevec) may be used for tumors with the c-KIT mutation.

Question 232

Primary malignant tumors arising from the Bartholin gland can be

Answer 232

adenocarcinomas, squamous cell carcinomas, or transitional cell carcinomas.

Question 233

growth fraction

Answer 233

The speed with which tumors grow and double in size is largely regulated by the number of cells that are actively dividing

Question 234

Adjuvant chemotherapy

Answer 234

is given to destroy remaining microscopic cells that may be present after the primary tumor is removed by surgery.

Question 235

Neoadjuvant chemotherapy

Answer 235

refers to drug treatment directed at an advanced cancer to decrease preoperatively the extent or morbidity of a subsequent surgical resection.

Question 236

Consolidation (or maintenance) chemotherapy

Answer 236

is given after cancer has disappeared following the initial therapy and ainu to prolong the duration of clinical remission or to prevent ultimate relapse.

Question 237

salvage (or palliative) chemotherapy

Answer 237

Therapy applied to recurrent disease or to a tumor that is refractory to initial treatment.

Question 238

Gemcitabine MOA, uses and side effects

Answer 238

antimetabolite is FDA approved to be used with other agents for treannent of recurrent ovarian cancer but is also commonly used for uterine sarcoma, Myelosuppression, especially neutropenia. is the main dose-limiting side effect. Gastrointestinal (GI) toxicity, such as nausea. vomiting. diarrhea, or mucositis, also is common.
Approximately 20 percent of patients will develop a flulike syndrome, including fever, malaise, headache, and chills. Pulmonary toxicity is infrequent. but reported.

Question 239

Ifosfamide uses, side effects

Answer 239

Recurrent ovarian CA, cervical CA, CNS and uterine sarcoma(not FDA approved)

BMD, cystitis, N&V ,alopecia, and renal toxicity, its metabolic activation occurs more slowly and leads to a greater production of chloracetaldehyde, a possible neurotoxin. neurotoxicity, manifested as lethargy, confusion, seizure, ataxia, hallucinations, and occasionally coma, is more likely.

Question 240

Cyclophosphamide uses, MOA, side effects

Answer 240

Cyclophosphamide is the “C” of EMACO in GTN, used as salvage therapy for recurrent epithelial ovarian cancer.
It’s alkylating agents is characterized by positively charged alkyl groups that bind to negatively charged DNA to form adducts. Binding leads to DNA breaks or cross-links and a halt to DNA synthesis. In general, these drugs are cell cycle-nonspecific agents.
Myelosuppression, mainly neutropenia, is the usual doselimiting side effect. One of its metabolites, acrolein, can alkylate and inflame the bladder mucosa. As a result, hemorrhagic Cystitis is a classic complication that may follow from 24 hours to several weeks after administration. To prevent this effect, adequate hydration is imperative to aid acrolein excretion. In addition, Gl toxicity, such as nausea, vomiting, or anorexia, is common. Alopecia. secondary malignancy rates are increased, particularly acute myelogenous leukemia and bladder cancer. ovarian function damage. Preventatively, adjuvant gonadotropin-releasing hormone (GnRH) agonists may lower rates of chemotherapy-induced ovarian failure (controversial) ovarian tissue cryopreservation make it likely that the removal of oocytes prior to treatment will become the preferred approach when feasible

Question 241

Dactinomycin uses, MOA, excretion,side effects

Answer 241

antitumor antibiotic FDA approved to treat GTN as a single agent or as part of combination chemotherapy, Dactinomycin (Cosmegen), also known as actinomycin D, is the “A” of the EMA-CO chemotherapy combination.
Dactinomycin becomes anchored into purine-pyrimidine DNA base pairs, resulting in DNA synthesis inhibition. It also produces toxic oxygen free radicals that cause DNA breaks.
excreted mainly through the biliary system.
Myelosuppression is the main dose-limiting side effect and may be severe.GI toxicity, including nausea, vomiting, mucositis, and diarrhea, Alopecia, potent vesicant.

Question 242

Bleomycin uses, MOA, side effects

Answer 242

antitumor antibiotic FDA approved for malignant pleural effusion treatment or for palliative therapy of recurrent squamous cervical or vulvar cancer. An off-label use includes bleomycin as the “B” in BEP (bleomycin, Etoposide, cisplatin) regimens, which are used as adjuvant treatment of malignant ovarian germ cell or sex cord-stromal tumors.used in GlN salvage treatment.
Bleomycin (Blenoxane), when complexed with iron, creates activated oxygen free radicals, which cause DNA strand breaks and cell death. It is maximally effective during the G2 phase. Pulmonary toxicity is the main dose-limiting side effect, not myelosuppressive. However, skin reactions are common and include hyperpigmentation or erythema.

Question 243

the main dose-limiting side effect of bleomycin is Pulmonary toxicity, by how much percentage ? And how to monitor/dx it ?

Answer 243

developing in 10 percent of patients and causing death in 1 percent. Accordingly, for women prescribed bleomycin, chest radiographs and pulmonary function tests (PFTs) are performed at baseline and obtained regularly before every one or two treatment cycles. The most important PFT measurement is the diffusing capacity of the lung for carbon monoxide (DLCO). The DLCO measures the ability to transfer oxygen from the lungs to the blood stream. If the DLCO declines by 15 to 30 percent, it indicates development of restrictive lung disease. Fibrosis often presents clinically as pneumonitis with cough, dyspnea, dry inspiratory crackles, and infiltrates on chest radiograph.

Question 244

Doxorubicin uses, MOA, metabolism and excretion, side effects

Answer 244

antitumor antibiotic is FDA approved to treat epithelial ovarian cancer, but doxorubicin (Adriarnycin) is more frequently used for uterine sarcoma.
This agent intercalates into DNA to inhibit DNA synthesis, inhibits topoisomerase II, and forms cytotoxic oxygen free radicals. The drug is metabolized extensively in the liver and eliminated through biliary excretion.
Myelosuppression, particularly neutropenia, is the main dose-limiting side effect. However, cardiatoxicity is a classic complication. irreversible dilated cardiomyopathy associated with congestive heart failure. Gastrointestinal toxicities are generally mild, but alopecia is universal.

Question 245

cardiatoxicity is a classic complication of treatment with doxorubicin, how to monitor?

Answer 245

Patients are monitored with a multiple-gated acquisition (MUGA) radionuclide scan at baseline and periodically during therapy. The risk of cardiotoxicity is higher in women older than 70 and those with cumulative doses exceeding 550 mg/m2.

Question 246

Doxorubicin Liposome uses , MOA, side effects

Answer 246

antitumor antibiotic is FDA approved and commonly used for the salvage treatment of recurrent epithelial ovarian cancer. The liposomal encapsulation of doxorubicin (Doxil) dramatically alters the pharmacokinetic and toxicity profiles of the drug. Researchers developed liposomal doxorubicin to reduce cardiotoxicity and to selectively target tumor tissues. contrast to doxorubicin, administration of the encapsulated liposome is associated with minimal nausea, vomiting, alopecia, Infusion-related reactions develop in less than 10 percent of patients and are most common during the first treatment course. However, an increased rate of stomatitis and palmar-plantar erythrodysesthesia (PPE) is noted.

Question 247

palmar-plantar erythrodysesthesia (PPE) is characterized by

Answer 247

Patients may initially complain of tingling sensations on their soles and palms that generally progress to swelling and tenderness to touch. Erythematous plaques typically develop that can become extremely painful and often lead to desquamation and skin cracking. Symptoms result from the prolonged blood levels of cytotoxic agent and may last several weeks.

Question 248

Vinca Alkaloids (Vincristine, vinblastine, and vinorelbine) uses, MOA, side effects

Answer 248

are cell cycle-specific in the M phase. These compounds inhibit normal microtubular polymerization by binding to the tubulin subunit at a site distinct from the taxane-binding site. vincristine is the “O” of EMA-CO combination chemotherapy for GTN treatment.
the most common dose-limiting toxicity and may include peripheral neuropathy, autonomic nervous system dysfunction, cranial nerve palsies, ataxia, or seizures. Moreover, concurrent administration with other neurotoxic agents such as cisplatin and paclitaxel may increase severity. GI toxicity also is common, including constipation, abdominal pain, and paralytic ileus. However, myelosuppression is typically mild.

Question 249

Topotecan MOA, uses, side effects

Answer 249

This TOPO I inhibitor binds to and stabilizes a transient TOPO I-DNA complex. This results in double-strand breakage and lethal DNA damage.
FDA approved as salvage therapy of recurrent epithelial ovarian cancer and recurrent cervical cance.
Myelosuppression, most commonly neutropenia, is the main dose-limiting side effect. GI toxicity also is frequent and includes nausea, vomiting, diarrhea, and abdominal pain. Systemic symptoms such as headache, fever, malaise, arthralgias, and myalgias are typical. Alopecia.

Question 250

Etoposide MOA, uses, side effects

Answer 250

cell cycle-specific agent has maximal activity in the late S and G2 phase. Etoposide “poisons” the TOPO II enzyme by stabilizing an otherwise transient form of the TOPO II-DNA complex. As a result, DNA cannot unwind, and double-strand DNA breaks form.
This agent is not FDA approved for gynecologic cancers. However, it is most often used IV as part of combination chemotherapy. Etoposide (VP-16) represents the “E” of the EMA-CO regimen, which is used for GTN. In BEP regimen, used for ovarian germ cell or sex cord-stromal tumors.
Up to 95 percent of etoposide is protein-bound, mainly to albumin. Thus, decreased albumin levels result in a higher fraction of free drug and potentially a higher incidence of toxicity. Myelosuppression, most commonly neutropenia, is the main dose-limiting side effect. GI symptoms of nausea, vomiting, and anorexia are usually minor, except with oral administration. Most patients will develop alopecia, later secondary malignancy is a small (approximately 1 in 1000) but significant risk. Acute myelogenous leukemia is the most common secondary cancer.

Question 251

Carboplatin MOA, uses, side effects

Answer 251

cell cycle-nonspecific drugs, produces DNA adducts that inhibit DNA synthesis. This agent is one of the most widely used, particularly in adjuvant or salvage treatment of epithelial ovarian cancer, and is FDA approved for this indication. It is also frequendy used off-label for endometrial cancer.
Myelosuppression, most commonly thrombocytopenia, is the main dose-limiting side effect. GI toxicity and peripheral neuropathy are notably less severe than with cisplatin. Hypersensitivity reactions will eventually develop in up to 25 percent of women receiving more than six cycles.

Question 252

Cisplatin MOA, uses, side effects

Answer 252

this agent produces DNA adduces that inhibit DNA synthesis. Cisplatin is one of the oldest and most widely used agents and is FDA approved for ovarian, cervical, and germ cell cancer. It may be given concomitandy with radiation as a radiosensitizing agent for primary treatment of cervical cancer or given as a single agent or in combination for recurrent cervical cancer. Alternatively, cisplatin is part of combination chemotherapy as the “P” of BEP, given for ovarian germ cell or sex cord-stromal tumors. Cisplatin has several significant toxicities. Of these, nephrotoxicity is the main dose-limiting side effect. Accordingly, patients must be aggressively hydrated before, during, and after drug administration. Mannitol (1 0 g) or furosemide (20 to 40 mg) may be necessary to maintain a urine output of at least 100 to 150 mL/hour. With cisplatin, electrolyte abnormalities, such as hypomagnesemia and hypokalemia, are common. In addition, severe, prolonged nausea and vomiting can be dramatic without adequate premedication. metallic taste and loss of appetite following treatment. Neurotoxicity, usually in the form of peripheral neuropathy, can also be dose limiting and irreversible. Ototoxicity typically manifests as high-frequency hearing loss and tinnitus. Similar to carboplatin, hypersensitivity reactions may develop with prolonged use. Overall, cisplatin is significandy more toxic than carboplatin, except for its reduced hematologic toxicity.

Question 253

megestrol acetate (Megace) MOA, uses, side effects

Answer 253

Synthetic derivative of progesterone and has activity on tumors through its antiestrogenic effects.
is most often used to treat endometrial intraepithelial neoplasia (EIN), nonoperable endometrial cancer, and recurrent endometrial cancer, especially in those patients with grade 1 disease.
Megestrol acetate has minimal toxicity, but patients often gain wdght from a combination of 8uid retention and increased appetite. Thromboembolic events are rare. Patients with diabetes mellitus arc carefully monitored because of the possibility of exacerbating hyperglycemia due to its concurrent glucocorticoid activity.

Question 254

bevacizumab (Avastin) uses, MOA, side effects

Answer 254

FDA approved for persistent, recurrent, or metastatic cervical cancer. For advanced epithelial ovarian cancer, bevacizumab is coupled with chemotherapy after initial surgery and then wed as single-agent maintenance. Last, it is suitable for relapsed platinum-resistant epithelial ovarian.
GI perforation may occur in up to 10 percent of patients (Cannistra, 2007). This complication is more likely in women with preexisting inflammatory bowel disease or in those with bowel resection at their primary surgery for advanced ovarian cancer (Burger, 2014). Elevated blood pressure is common and may lead to hypertensive crisis. Other possible toxicities include incomplete wound healing. weakness, pain, nosebleed. and proteinuria.

Question 255

Poly(ADP) Ribose Polymerase Inhibitors (PARP inhibitors) uses, MOA, side effects

Answer 255

Homologous recombination (HR) is an important pathway that repairs double-strand breaks, and PARP repairs single strand breaks. In the functioning cell, if HR does not repair the break. PARP will. If PARP repair is prevented, cancer cell DNA cannot be repaired and cells die. In contrast, normal cells are unaffected.
PARP inhibitors are now FDA approved for maintenance treatment of recurrent epithelial ovarian cancer following a complete or partial response to platinum-based chemotherapy. All three prolong survival, regardless of HR deficiency gene status, yet allow suitable quality of life during therapy. Olaparib is used for BRCAl and BRCA2 mutation carriers with relapsed ovarian cancer that has demonstrated resistance to platinum drugs. The most frequent toxicity is anemia. but other side dfects are fatigue, nausea or abdominal pain Niraparib has Most signficant side effects are hematologic and can be managed with dose adjustments. Rucaparib is used for patients with a BRCA mutation (germline or somatic) and with recurrent epithelial ovarian cancer treated by two or more courses of therapy.

Question 256

pembrolizumab uses, MOA, side effects

Answer 256

passive immunotherapy agents a therapeutic humanized antibody that targets and blocks the programmed cell death 1 (PD-1) receptor of T cell lymphocytes. approved for any unresectable or metastatic solid tumor with MSI-H or MMR deficiencies and for advanced cervical cancer in PD-Ll-positive patients. the response rate approximates 15 percent. Side effects are few and include rash and fever.

Question 257

Management of emetogenic cytotoxic medications

Answer 257

Mild nausea and vomiting can often be managed effectively by prochlorperazine (Compazine} with or without dexamethasone.

Question 258

Peripheral neuropathy can be seen with which chemotherapies

Answer 258

cisplatin, paclitaxel, and the vinca alkaloids. Cisplatin-induced neurotoxicity usually resolves slowly, due to axonal demyelination and loss. To counter this toxicity, amifostine (Ethyol) may be administered, but substitution of carboplatin will avoid much of the toxicity. Gabapentin (Neurontin) is the usual treatment for neuropathic pain

Question 259

Electromagnetic Radiation Energy Deposition Three mechanisms are involved in energy transfer:

Answer 259

(1) photoelectric effect,
(2) Compton effect,
(3) pair production
The photoelectric effect is dominant if the incident energy is low (less than 100 kV). The Compton effect dominates in mid-to high energy ranges (1 MY to 20 MV) and is the most important in clinical radiation therapy. Last, pair production occurs when a photon beam with very high energy (beyond 20 MV) strikes the electromagnetic field of the nucleus.

Question 260

Radiosensitivity of Some Selected Cancers Sensitivity

Answer 260

Highly sensitive: Lymphoma, dysgerminoma, small cell cancer, embryonal cancer
Moderately sensitive: Squamous carcinoma, adenocarcinoma
Poorly sensitive: Osteosarcoma, glioma, melanoma

Question 261

Taxanes, such as paclitaxd and docetaxd MOA, uses, side effects

Answer 261

causing microtubule dysfunction and blocking cells at the G2/M junction
enhance the effects of radiation with platinum agent

Question 262

Postoperative radiation is employed in the treatment of many gynecologic malignancies. Such as

Answer 262

For cervical cancer, postoperative radiation is recommended in those with lymphovascular invasion, deep stromal invasion, or large tumor size
Postoperative chemoradiation is offered if positive parametria, positive margins, or positive lymph nodes are found.
For uterine cancer, postoperative radiation is frequendy used for patients with stage IB or greater disease. intermediate-risk endometrial adenocarcinoma (includes older age, lymphovascular invasion, deep myometrial invasion, or intermediate-or high-grade disease )for adjuvant pelvic radiation.

Question 263

the most consistent sequela of radiation therapy is

Answer 263

Atrophy, It affects all lining epithelia-including skin and the epithelia of the gastrointestinal, respiratory, and genitourinary tracts and of the endocrine glands. Additionally, necrosis and ulceration may develop. Within the submucosa and deep soft tissues, fibrosis frequendy follows radiation therapy, leading to tissue contracture and stenosis

Question 264

Side effects of radiotherapy

Answer 264

Tissue atrophy
acute vaginal mucositis, formation of vaginal synechiae or tdangiectasia, and most commonly, vaginal stricture. Less frequently, rectovaginal or vesicovaginal fistulas may devdop after radiation therapy, especially with advanced-stage cancers.
acute cystitis symptoms within 2 to 3 weeks of beginning treatment.
acute malabsorption syndrome ensues to cause nausea, diarrhea, vomiting, and cramping. Adequate fluid intake and a low-lactose, low-fat, and low-fiber diet is recommended. acute radiation nephropathy typically appear 6 to 12 months after radiation exposure. Affected patients develop hypertension, edema, anemia, microscopic hematuria, proteinuria, and decreased creatinine clearance. Radiation-induced insufficiency fractures. Radiation therapy can significantly deplete bone marrow hematopoietic stem cells that include erythrocyte, leukocyte, and platelet precursors. if platelet levels measure <35,000 X 109/L and leukocyte counts are <1.0 X 109/L, then radiation may be held until these values rise. For anemia, transfusion is recommended To spare bone marrow injury, IMRT may be beneficial

In the general population 12% of women will develop breast cancer during their lifetime. The lifetime risk of developing breast cancer with BRCA 1 is 55-65% and BRCA 2 is 45%
In the general population 1.3% of women will develop ovarian cancer during their lifetime. The lifetime risk of developing ovarian cancer with BRCA 1 is 40% and BRCA 2 is 15%

Question 278

Glandular neoplasia is often associated with cervical intraepithelial neoplasia (in –% of cases) and an underlying malignancy (adenocarcinoma) in –% of the cases.

Answer 278

Glandular neoplasia is often associated with cervical intraepithelial neoplasia (in 50% of cases) and an underlying malignancy (adenocarcinoma) in 40% of the cases.
Therefore, one smear test reported as glandular neoplasia needs urgent referral to colposcopy and the woman needs to be seen in the clinic within 2 weeks of referral (target referral).

Question 279

woman with a normal smear 3 years ago has her current smear reported as mild dyskaryosis, next step ?

Answer 279

According to recent NHS cancer screening guidelines, women with borderline and mild dyskaryosis are triaged to have high-risk HPV test. If the high-risk HPV virus is positive then they are referred for colposcopy. If the colposcopy is normal, they then go on to have routine recall in 3 or 5 years’ time depending on the screening age of patient. If the high-risk HPV test is negative then they go on to have routine recall in 3 years’ or 5 years’ time depending on the screening age of the patient.

Question 292

Tumor markers

Answer 292

Question 293

Anti-Yo progressive cerebellar degeneration

Answer 293

most commonly is associated with ovarian or breast carcinoma. Frequently, the neurologic disorder predates discovery of the tumor. The Yo antigen is one of three cerebellar degeneration-related antigens identified by expression cloning and causes direct toxicity to Purkinje cells, which may not be restored. Progressive cerebellar degeneration renders patients unable to walk, and dysarthria is frequently severe. Once the disorder reaches this stage, treatment with immunosuppression or effective treatment of the underlying malignancy rarely produces significant improvement.

Question 300

For risk-reducing salpingo-oophorectomy in patients with hereditary breast and ovarian cancer syndromes, chance of finding occult malignancy at surgery or during final pathologic analysis approximates – percent (Finch, 2006; Manchanda, 2011). Thus, preoperative serum CA125 level and pelvic sonography should evaluate for malignancy.

Answer 300

For risk-reducing salpingo-oophorectomy in patients with hereditary breast and ovarian cancer syndromes, chance of finding occult malignancy at surgery or during final pathologic analysis approximates 5 percent (Finch, 2006; Manchanda, 2011). Thus, preoperative serum CA125 level and pelvic sonography should evaluate for malignancy.

Question 301

Pelvic ultrasonography of the ovaries can be useful for evaluating the presence of an ovarian androgenproducing neoplasm in patients with markedly elevated testosterone concentrations, rapidly progressive hirsutism, or signs of virilization.

Answer 301

Many of the ovarian androgen-producing neoplasms can be small and may not be clearly identified on ultrasonography. Sometimes the only way to identify an ovarian neoplasm is by noting asymmetry of the ovaries on ultrasonography or growth over time.

Question 312

Natural History of Cervical lntraepithelial Neoplasia (CIN) Lesions

Answer 312

The risk of progression of biopsied but untreated CIN 3 to invasive cancer approximates 30 percent over 30 years (McCredie, 2008).

Question 313

Cytology-negative and HPV-positive test results will occur in <10 percent of screened patients

Answer 313

co-testing is repeated 12 months later. Colposcopy is recommended for recurrent, positive HPV results or an abnormal repeat cytology.
An alternative strategy is now available for the manage- ment of normal cytologic findings but a positive HPV result. A reflex test specifically for HPVs 16 and 18, (genotyping) can be performed in many settings. If HPV 16 or 18 is found, immediate colposcopy is recommended (American College of Obstetricians and Gynecologists, 2018a; Saslow, 2012).

Question 314

Endocervical sampling is cur- rently recommended during colposcopy for the following situ- ations (American College of Obstetricians and Gynecologists, 2018b; Massad, 2013):

Answer 314

• The SCJ is not fully visualized.
• The SCJ is fully visualized, but no lesion is identified.
• Initial evaluation of ASC-H, HSIL, AGC, or AIS cytology
test results.

Question 315

IF Histologic LSIL (HPV changes or CIN 1) WAS found
WHAT IS THE PROPER MANGAMENT ?

Answer 315

exhibits high rates of spontaneous regression. The LSIL diagnosis is poorly reproducible by cytology or histology and is thus unreliable. Pt should not be told they have HPV infection based upon LSIL cytology or biopsy alone. For these reasons, HPV change found by biopsy is not treated, and CIN 1 is no longer treated immediately. When diagnosed after a “lesser” cytologic abnormality such ASC-US, LSIL, or an NILM, HPV-positive screening, it can be observed indefinitely. Treatment is accept- able only ifCIN 1 persists for more than 2 years. This is regard- less of colposcopic examination adequacy or presence of CIN 1 in an endocervical sampling. Treatment of CIN 1 in younger women or chose concerned about the possible effects of treat- ment on future pregnancy is discouraged. Current guidelines for surveillance without treatment and criteria that return a woman to routine screening should be followed and may involve periodic cytology or co-testing.
Ifdeemed appropriate, persistent CIN 1 can be treated by ablation. Criteria require that the SCJ and all lesions are fully seen during colposcopy and that the endocervical sampling lacks HSIL (CIN 2/3) or ungraded CIN. If these criteria are not met and treatment is indicated, excision is recommended and ablation is unacceptable.
CIN 1 diagnosed after an ASC-H or HSIL Pap test result carries a higher risk of undiagnosed high-grade CIN. Depending on patient age and colposcopic findings, either a diagnostic excision or surveillance with colposcopy, cytology, HPV testing, or a combination of these at prescribed intervals will be recommended by current guidelines. Persistent, unex- plained HSIL or AGC cytology generally warrants an excision procedure, if only CIN 1 is found with colposcopic biopsy.
(CIN severity, colposcopic findings, age, and reproductive plans play key roles in cervical disease man- agement. Guidelines are complex and applied on an individual- ized basis. They cannot address all patient scenarios and cannot prevent all cases o f cervical cancer.)

Question 316

Management of HSIL:CIN2 and CIN3 ?

Answer 316

Treatment modalities include either ablation or excision of the entire TZ.
An unequivocal histologic diagnosis of CIN 3 is always treated and not observed in nonpregnant patients regardless of age or reproductive history. With a CIN 3 biopsy, if HSIL or ungraded CIN is found in the endocervical sampling or if col- poscopy did not fully visualize the SCJ and the upper limits ofall lesions, a diagnostic excision is indicated to exclude occult inva- sive cervical cancer. Recurrent or persist HSIL after treatment is managed with repeat excision, not ablation. Hysterectomy as primary therapy is unacceptable. Hysterectomy may be indi- cated if repeat excision is needed but not anatomically feasible or if high-grade CIN recurs or persists and invasive cancer has been thoroughly excluded. For young women, particularly of low parity, with CIN 2 or HSIL (CIN 2/3, not otherwise specified) surveillance or treat- ment is acceptable, ifthe SCJ and all lesions are fully seen during colposcopy. In this context, “young women” refers to individu- als for whom the possible risk to future pregnancies from treat- ment outweighs the risk of progression to malignancy, although both are difficult to quantify. No upper age limit is specified for surveillance. Surveillance o f specified CIN 2 is preferred in younger women, because this histologic diagnosis is less reli- able and spontaneous regression of lesions over time is com- mon. Even in younger women or those concerned with future reproduction, treatment is indicated ifcolposcopy does not fully visualize the SCJ and lesions present, biopsy shows CIN 3, or if CIN 2 or CIN 2/3 is persistent. Current guidelines for surveil- lance testing, intervals for reassessment, and acceptable upper time limits for persistence should be consulted.

Question 317

Ifan excision margin or endocervical curettage performed immediately after an excision is positive for HSIL (CIN 2 or CIN 3), next step ?

Answer 317

repeat excision may be indicated.
Repeat excision is indicated for special circumstances such as AIS or microinva- sive carcinoma at the excision margins.

Question 318

Vulvar cancer treatment (based on staging)

Answer 318

1) Wide local excision (AKA simple partial vulvectomy) can be appropriate for preinvasive disease and microinvasive tumors (stage IA) of the vulva and some rare histologic types with a 1-cm surgical margin is obtained around the lesion. Deep surgical margins corresponds to Colles fascia measuring 1 cm.
2) radicalpartial vulvectomy, tumor-containing portions of the vulva are completely removed, wherever they are located. Skin margins are ideally 2 cm, and excision extends deep to the perineal membrane.
3) Radical partial vulvectomy is typically reserved for lesions that are not too large or extensive, with an otherwise normal vulva.
Radical total vulvectomy is a complete dissection ofvulvar tissue to the level ofthe perinea! membrane and the periosteum of the pubic rami or symphysis.

Question 319

Microinvasive Tumors (Stage IA) vulvar ca management

Answer 319

these patients can undergo wide local excision with a 1-cm margin. Lymphadenectomy is not indicated because associated lymph node metastasis is rare.

Answer 324

Endometrial adenocarcinomas are categorized as rype I or rype II based on histology. Type I, that is, endometrioid rype, makes up 80 to 90 percent ofall cases. The other 10 to 20 percent are rype II cancers, namely, the non-endometrioid hiscologic rypes that include serous and clear cell adeno- carcinomas and carcinosarcoma.

Question 325

Postmenopausal bleeding is particularly worrisome and carries a – to –percent likelihood of diagnosing endometrial carcinoma (Clarke, 2018; van Hanegem, 2017). Abnormal vaginal discharge may be another symptom in older women.

Answer 325

Postmenopausal bleeding is particularly worrisome and carries a 5- to 10-percent likelihood of diagnosing endometrial carcinoma (Clarke, 2018; van Hanegem, 2017). Abnormal vaginal discharge may be another symptom in older women.

Question 326

postmenopausal women with endometrial cells are occasionally recorded on a routine Pap test report what is her risks of endometrial cancer ? percentages

Answer 326

postmenopausal women with such findings have a 3- to 5-percent risk ofendometrial cancer (Simsir, 2005) In those using H RT, the prevalence of benign endometrial cells on smears is greater, and the risk of endometrial malignancy is low (1 to 2 percent)

Question 327

Only three classes of cytotoxic drugs with definite activity for endometrial cancer have been identified,Which are

Answer 327

and paclitaxel (Taxol), doxorubicin {adriamycin), and cisplatin (TAP) chemotherapy is one of the adjuvant treatment options for advanced endomtrial cancer following surgery. In one GOG trial of273 women (protocol #177) A less toxic alternative to TAP chemotherapy is paclitaxel plus carboplatin. Routinely used for ovarian cancer, this regimen is effective in advanced-stage endometrial cancer (Hoskins, 200 I; Sovak, 2006, 2007). One GOG trial (protocol #209) compared TAP and the regimen of carboplatin plus paclitaxel. Results demonstrated that carboplatin plus paclitaxel was not inferior to TAP in terms of progression-free and overall survival rates.

Question 335

Treatment of ovarian cancer:
• Primary treatment can be surgical, via primary debulking surgery (PDS) or with NACT.
• Surgery usually consists of an exploratory laparotomy, abdominal cytology, hysterectomy, BSO, omentectomy, and cytoreduction.

Answer 335

with evidence of up to stage IIIB cancer should be surgically staged to include peritoneal biopsies and a pelvic and PA-LND. Three-fourths of advanced-stage cancers will have positive retroperitoneal LN. LN drainage tends to follow the ovarian vessels. Dissection around the high precaval and PA regions is important.
