Q

Risk Reducing BSO

A

decreased ovarian by 96% and Breast by 53%

Risk of primary peritoneal cancer after
salpingo-oophorectomy: 4%
 Occult ovarian cancer at the time of surgery:
2-17%

BRCA1 35-40
BRCA2 40-45

Can consider for other genes for ovarian ca like lynch

Q

ovarian cancer work-up

A

Most helpful imaging:
 Pelvic ultrasound
 CT abdomen/pelvis with PO and IV contrast
 Most helpful labs:
 CA-125, CA 19-9, CEA
 Inhibin B, HCG, AFP, LDH, testosterone (if younger, solid
mass, or hyperestrogenism/androgenism)

Q

Staging surgery for Ovary

A
􀀀 Vertical midline incision
􀀀 Obtain peritoneal cytology
􀀀 Intact tumor removal
􀀀 Complete abdominal exploration
􀀀 Removal of remaining ovaries, uterus, tubes
􀀀 Pelvic/para-aortic lymphadenectomy
􀀀 Omentectomy
􀀀 Random peritoneal biopsies
􀀀 Appendectomy (particularly if mucinous)

Q

Surveillance with ovarian Cancer

A

Visit with exam every 3 months x 2 years, 6 months x 3 yrs
 CA-125 optional
 Imaging if concern for recurrence

16
Q

Low Grade Serious

A

Similar progression free survival (19 months), but longer
overall survival (82-99 months)
 More chemotherapy resistance
 Treat with (aggressive) surgery
 Hormonal therapy (GnRH, aromatase inhibitors,
progesterones)

17
Q

Borderline Work-up

A
Surgical staging
 25-30% with extra-ovarian
disease
 Up to 25% will have invasive
disease on final path
 Peritoneal biopsies and omentectomy
 Oophorectomy
 Appendectomy if mucinous
 Lymphadenectomy “case by case”
18
Q

Borderline Treatment

A

Excellent survival > 98%
 Even if no invasion or non-invasive implants, recurrence
is possible (~30% after fertility sparing surgery)
 Surveillance is needed
 Visits with exam every 3-6 months
 Pelvic ultrasound if fertility sparing surgery – every 6-12
months?
 CA-125?
 Unsure value of completion hysterectomy/USO after
childbearing, may consider

19
Q

Immature Teratoma

A
20% of primitive germ cell tumors (3% of
teratomas)
 Contains immature neural elements/tubules
 Only GCT that is graded
 Tumor marker: none (sometimes AFP)
 Surgery – USO and staging
 Adjuvant therapy
 Early stage (IA): none required
 All other stages: Bleomycin/etoposide/cisplatin
 Overall survival 70-80%
20
Q

Dysgerminoma

A

Most common malignant germ cell tumor (50%)
 Bilateral in 15%
 Tumor marker is LDH (8% HCG, no AFP)
 Abnormal karyotype in 5% of patients (associated
with gonadoblastoma)
 Surgical management includes:
 USO and staging
 BSO if abnormal karyotype (gonadoblastoma)
 Debulking of uncertain value
Adjuvant therapy for advanced disease
 Chemotherapy (BEP)

21
Q

Endodermal Sinus Tumor

Yolk sac tumor

A

20% of germ cell tumors
 Median age 18 years
 Tumor marker is AFP
 Schiller-Duval bodies on path (central capillary surrounded by
connective tissue and layer of columnar cells)
 Surgical goal is diagnosis
 All patients will require adjuvant treatment
 Bleomycin/etoposide/cisplatinum or radiation therapy
 Poor survival (even with early stage)

22
Q

Embryonal, Choriocarcinoma,

Polyembryoma

A

 Very rare cancers
 Tumor marker is hCG
 Poor survival due to late diagnosis
 Treat with BEP or GTN regimen

23
Q

Granulosa Cell Tumor Markers

A

Estrogen, Inhibin, Testosterone, AMH

Call-Exner Bodies

24
Q

Sertoli Leydig

A

AFP, Estrogen, Inhibin, Testosterone >2.5x normal, Androsteindione, DHEA

may secrete renin (hypertension, hypokalemia)

Reinke Crystals

25
Q

Treatment for sex-cord stromal

A

TAH/BSO or fertility
sparing surgery, omentectomy and biopsies,
and/or complete tumor debulking; lymph
node involvement is rare

BEP or carbo/taxol

Do get an endometrial biopsy

26
Q

Meigs syndrome

A

Solid adnexal mass
Pleural Effusions
Ascites

  • usually fibroma (benign)
