EpidemiologySecond most common gynecological
cancer .
>35 , median 70
It accounts for deaths more than cancer of cervix and uterus together
EtiologyThe ovulation theoryGeneticsothers
Risk factors and PreventionRisk factors
Number of life time ovulationsage > 35 InfertilityNulliparity Late menopasueFamily historyBRCA 1 +2
PreventionUse of OCPBreastfeedingMultiparityTubal sterilization
GeneticsFamilial Ovarian cancer5-10% of epithelial cancers (usually serous
adencarcinoma)1 relative ---- 2.5% 2 relatives 30-40 %Most have breast and colorectal cancerBRCA 1 & BRCA 2 HNPCC
Primary vs Secondary
Histological type
Classification
Primary Vs SecondarySecondary : 7%Common primary cancers are breast cancer
and gastrointestinal cancer “Krukenberg tumour”
Histological origin
Epithelial Cell tumor85 % of malignant tumors
60-70 yrs
Worst prognosis
CEA , CA-125
Brenner
Clear cell
Endometroid
Mucinous
Serous
Borderline epithelial tumors10% of the epithelial cellsAtypia, mitotic activity , but no invasion of
the stromaGood prognosisMost are serous or mucinous
Germ Cell tumorSecond most common type of ovarian cancer5-10%20-40 yrsBetter prognosisLDH, AFP,B-HCG
Sex Cord TumorsLeast common ovarian neoplasm5-8 % of ovarian cancers and 30 % of all
tumorsLow grade malignancyHormonally active
Clinical findingsUsually absent or nonspecific GI symptomsUrinary symptomsPostmenopausal bleedingVirilizationAcute abdomen
Diagnosis – InvestigationsU\STumor markersBariun enemaIVPChest X-ray, abdominal X-rayCT/PET
U/S
Solid and cystic, septation, irregularly shaped
Diagnosis – Markers
Ovarian Tumor Serum markerDysgerminoma LDHEndodermal sinus
AFP
Choriocarcinoma B-HCGGranulosa tumor InhibinSertoli-leydig cell
Testosterone
MetastasisMainly through the peritoneal fluid
Lymphatic spread
Least common hematogeneous
ManagementSurgery: TAH/BSO Pelvic and aortic lymph node dissection OmentectomyAppendectomy Washings Biopsies
PrognosisThe five-year survival rate for all stages of
ovarian cancer is 45.5%.
Germ cell tumors of the ovary have a much better prognosis than other ovarian cancers, in part because they tend to grow rapidly to a very large size, hence they are detected sooner.
