Exam pt 2 Flashcards
what is the 4th most common CA in women
uterine CA
what is a hallmark of ovarian CA
intra-peritoneal spreads
2nd most common gynecologic malignancy with the highest mortality
Ovarian CA
*incidence increases w/ age and risk of relapse of advanced stage is 70%
pathogenesis hypotheses for ovarian CA
- repeated ovulation/ trauma/ repair to ovarian epithelium allow genetic mutations and neoplasia
- excess gonadtotropin secretion –> increased estrogen –> epithelial proliferation and potential for malignant transformation
- starts as carcinoma insitu in fallopian tubes –> breaks free and invades ovaries
____% of primary ovarian tumors derive from epithelial cells
90% *mostly serous
3% germ cells and 7% sex cord-stroma
___% diagnosed with stage III/IV ovarian CA
75%
____% 5 year survival of advanced stage ovarian CA
20%
risk factors for ovarian CA
- women w/ ovaries
- long ovulation hx
- unexplained infertility
- nuliparity
- fhx of breast or ovarian CA / BRCA**
- diet
- estrogen replacement
- hx of endometriosis
factors that decrease your risk for ovarian CA
- increased parity*
- oral contraceptive use*
- tubal ligation
- hysterectomy
*decreased ovulation
symptoms of ovarian CA
bloating, fatigue, increased abdominal size, urinary urgency, constipation
how do u evaluate an adenxal mass?
- transvaginal sonography (TVS)
- if normal rescan in 1 yr
- if abnormal evaluate tumor morphology index score, CA-125 biomarker, and color doppler
prevalence of adenxal mass
2-7%
*7.8% of premenopausal women had adenxal masses 2.5cm or larger on random u/s (ovarian cysts)
factors to consider when evaluating adenxal masses by TVUS
tumor size
borders
density
*morphology index score above 5 is concerning
what is an elevated CA-125 in a premenopausal woman and a postmenopausal woman
premenopausal >200
postmenopausal >35
*biomarker for ovarian CA but not specific!
how to treat an ovarian cyst
laparoscopy
tumor markers
HE4: ovarian CA
CA-125: ovarian and others
CEA: mostly GI tract
CA 19-9: mucinous tumors, pancreatic tumors
( if HE4 normal and CA125 elevated in premenopausal likely endometrosis)
screening for ovarian CA
there is no screening tool!
*just educate on signs
Can measure 5 protein in blood: Transthyretin apolipoprotein A-1 B2 microglobulin Transferrin CA 125 II
surgical staging for ovarian CA. What should be done?
- hysterectomy
- both tubes and ovaries (BSO)
- pelvic washings
- pelivic lymph nodes
- periaortic lymph nodes
- peritoneal biopsies
- diaphram scraping
- omentectomy/biopsy
stages for ovarianCA
Stage 1- stays where it started
Stage 2- spread next to the origin
Stage 3-spread outside pelvis
Stage 4- distally spread
treatment of ovarian CA
- chemotherapy (IV or intraperitoneal)
- platiunum and taxane (6 cycles of 21 days)
- clinical trials
- surgery
**Platinum drugs are the most effective (carboplatin or cisplatin)- but some are resistant to it
surveillance of ovarian CA after no evidence of disease
- 5 yr prognosis
- visit every 3 months for 2 years, then may space out
- H and P
- CA125
- imaging?
what percent of ovarian CAs are genetic?
10%
of that:
BRCA1 ~70-75%
BRCA2~ 20%
what is a significant family hx of ovarian CA
-2 first degree relatives (Breast or ovarian CA OR 1
screening for ovarian CA if BRCA +
- monthly BSE starting at 18
- annual mammograms at 25
- annual breast MRI
- 2x yearly ovarin screening w/ us and CA125 at 35
how can u reduce ones risk of ovarian CA if they are BRCA +
- screening
- surgery
- chemoprevention
*BSO reduces ~95%
Mastectomy ~40-50%
most common gyn malignancy in developed countries
endometrial CA
95% of uterine CA are endometrial, 5% are sarcomas
median age of endometrial CA
61
major risk factor for type I and type II endometrial CA
type I- unopposed estrogne
type II- age
80% of endometrial CA race: caucasian > black differentiation: well differentiated histology: grade 1 or 2, endometrioid Prognosis: favorable
type 1 endometrial CA
10-20% of endometrial CA race: caucasian = black differentiation: poorly differentiated histology: grade 3, serous, clear cell, mucinous, etc. Prognosis: poor
type 2 endometrial CA
risk factors of endometrial CA
- unopposed estrogen (type 1 only)
- obestity
- late menopause
- nulliparity
- diabetes
- hypertension
- tamoxifen
- endometrial hyperplasia
% risk of
simple endometrial hyperplasia w/o atypia
complex endometrial hyperplasia w/o atypia
simple endometrial hyperplasia with atypia
complex endometrial hyperplasia with atypia
1%
5%
10%
25%
*think coin size
factors that decrease risk of endometrial CA
- decrease estrogen or increased progesterone
- oral contraceptives
- pregnancy
- smoking
signs and symptoms of endometrial CA
abnormal bleeding
what do u do if someone presents w/ abnormal bleeding?
aka how do u dx endometrial CA
Biopsy!!!- endocervix and endometrium
-US:
___% of endometrioid ovarian CA have a synchronous endometrial CA
20%
what other CA has a 40-60% lifetime risk of endometrial CA
hereditary non-polyposis colorectal CA syndrome (Lynch syndrome)
**recommend prophylactic hysterectomy
spread patterns of endometrial CA
- direct extension- most common
- transtubal
- lymphatic
- hematogenous- mostly lungs
treatment of endometrial CA
- surgical staging
- postop radiation or chemo
- medical managment (progesterone, anti-estrogen?)** used as palliative care

young worse than old
2cm
hormone receptor status: + better than neg.
prognosis for stage IA endometrial CA
prognosis for stage IVB endometrial CA
88%
15%
most common gynocologic CA worldwide but not in US because of screening prevention
cervical CA
risk factors of cervical CA
HPV infection smoking multiple partners multiparity HIV STDs OCP use low socioeconomis status poor diet (Vit. deficiency) alcoholism
screening for cervical CA
PAP
*76% reduction in incidnece of invasive cervical CA
what HPV strains cause the most cervical CA
HPV 16 and 18 cause >70%
HPV 16 alone causes about 50%
symptoms of cervical CA
frequently asymptomatic
- abnormal vaginal bleeding
- postcoital bleeding
- vaginal discharge: watery, mucoid, purulent, and/or malodorous
- do not confuse with cervicitis

pruritus (severe itching)
burning
nonspecific irritation
appreciation of a mass
how do you dx vulvar CA
biopsy everything
most common vulvar CA subtypes
squamous 90%
melanoma 5%
Basal 2%
Staging of vulvar CA is based on what
midline lesion?
radical vulvectomy
inguinal lymphnodes (>1mm invasion)
Stages of vulvar CA
Stage 1: confined to vulva
Stage 2: extension to adjacent structures
Stage 3: positive inguinal femoral lymph nodes
Stage 4: upper 2/3 of urethra, upper vagina, distant
treatment of paget disease of the vulva
-wide local excision or vulvectomy 2cm margins is preferred
-radical vulvectomy
+/- lymph node dissection
+/- chemo/radiation
*60% experience local recurrence and may require 5cm margins
vulva is diffusely involved, with very thin, whitish epithelial areas, termed “onion skin” epithelium or “cigarette paper”
lichen sclerosus
an itch that rashes
itching contributes to epidermal thickening or hyperplasia and inflammatory cell infiltrate, which in turn leads to heightened sensitivity that triggers more mechanical irritation
Lichen Simplex Chronicus
rare inflammatory skin condition that can be generalized or isolated to the vulva and vagina
Sx:
whitish, lacy bands of keratosis near the reddish ulcerated-like lesions
chronic vulvar burning
pruritus
insertional dyspareunia
profuse vagina discharge
Lichen Planus
lesion: atrophic, thin, whitish epithelium w/ frequent perianal halo or keyhole distrubution
lichen sclerosis
lesion: pale red to yellowish pink plaques, often oily appearing, scaly crust
seborrheic
lesion: eczematous lesions w/ underlying erythema
dermatitis (allergic, irritant, or atopic)
