Origins of ovarian neoplasms
Sex-cord stromal tumours
Surface epithelial stromal tumours
Germ cell tumours
Epithelial tumours - prevalence
90% of ovarian neoplasms
Epithelial tumours - histological types
Serous (tubal)
Mucinous (endocervical)
Endometroid (endometrium)
Epithelial tumours - benign tumours subclassification
Cystic (cystadenomas)
Fibrous (adenofibromas)
Cystic and fibrous (cystadenofibromas)
Epithelial tumours - malignant types
Cystadenocarcinomas
Germ cell tumours - types
15-20% of all ovarian tumours
Germinomatous - dysgerminomas
Non-germinomatous - teratomas (mature, immature (malignant), yolk sac tumours, choriocarcinomas)
Germ cell tumours - treatment
Surgical +/- chemo/radio
Sex cord stromal tumours -
Rare, from ovarian stroma
Can generate cells of opposite sex
Sex cord stromal tumours - types
Thecoma/fibrothecoma/fibroma - benign, produce E2, fibromas hormonally inactive. Comprised of spindle cells. Meig’s syndrome
Granulosa cell - low grade malignant, produces E2
Sertoli-Leydig - produces androgens, 10-25% malignant
Ovarian cancer -
2nd commonest gynae cancer
Ovarian cancer - risk factors
FH Elderly PMH breast cancer Smoking E2-only HRT Lynch II syndrome Obesity Nulliparity
Ovarian cancer - protective factors
OCP

FIGO
Ovarian cancer - treatment
Stage TAH/BSO
Omentectomy, appendectomy, lymphadenectomy & adjuvant chemo
Chemo is only done in sensitive germ tumours
Ovarian cancer - prognosis
5 years 43% survival
Ovarian cancer - metastatic tumour types
Mullerian tumours (most common): uterus, fallopian, pelvic peritoneum, contralateral ovary
Extra-mullerian tumours: lymph/haem spread - GI, breast, melanoma, less commonly kidney and lung. Direct extension: bladder, rectal
Endometriosis summary
Spread of endometrium into the pelvis
Endometritis summary
Acute/chronic inflammation (usually due to infection)
Endometrial polyps summary
Local endometrial overgrowth
Leiomyomata summary
Benign smooth muscle tumours of the myometrium
Endometrial hyperplasia summary
Oestrogenic stimulation of endometrial proliferation; continuous stimulation may lead to atypical hyperplasia and carcinoma
