Slide 4

Cervical Carcinoma Once the most common cancer in women now not even in top 10. Decrease due to Pap test! At the same time, precursor lesions are increasing (early detection)

Slide 5

Cervical Intraepithelial Neoplasia (CIN) Precursor to carcinoma Almost all carcinomas arise in CIN; but not all cases of CIN progress to carcinoma! Three grades: CIN I: mild dysplasia (half regress, 20% progress) CIN II: moderate dysplasia CIN III: severe dysplasia (30% regress, 70% progress) The higher the grade, the more likely the lesion will progress to carcinoma

Slide 6

Cervical Carcinoma Risk Factors Early age at first intercourse Multiple sexual partners A male partner with multiple previous partners Persistent infection with high-risk HPV Smoking Immunodeficiency

Slide 7

Cervical Carcinoma and HPV HPV is detectable in almost all CIN and cancer. High-risk types: 16, 18, 45, 31 Found in carcinomas Integrate into genome, inactivate p53, RB Low-risk types: 6, 11 Found in condylomas (benign lesions) Do not integrate into genome

Slide 17

Invasive Cervical Carcinoma Most cases are squamous, arising from CIN Small number are adenocarcinomas Peak age: 45 (10-15 years after CIN develops!) Spreads slowly Most cases are diagnosed early Mortality is related to stage Stage 0 (preinvasive): 100% 5 year survival Stage 4: 10% 5 year survival

Female Reproductive System Outline Cervix Uterus Endometriosis Endometrial hyperplasia Tumors

Slide 21

Endometriosis Location of endometrial glands outside uterus Usually peritoneum, rarely lymph nodes Endometrium undergoes cyclic bleeding Causes scarring, pain, sometimes sterility How does endometrium get out?

Slide 22

Slide 23

Endometriosis in ovary (chocolate cyst)

Slide 24

Endometrial Hyperplasia Proliferation of endometrium due to estrogen excess Risk factors: anovulatory cycles, obesity, estrogen- producing ovarian tumors, exogenous hormone use Three categories: simple, complex, and atypical The more severe the hyperplasia, the greater the chance that it will evolve into carcinoma

Slide 25

Endometrial hyperplasia SimpleComplexAtypical

Slide 27

Leiomyoma Fibroid Benign tumor of smooth muscle Common! Stimulated by estrogen Menorrhagia, metrorrhagia, or asymptomatic

Slide 28

Leiomyosarcoma Malignant tumor of smooth muscle Necrotic, with atypical cells and lots of mitoses Often recur after surgery Many metastasize, especially to lungs 5 year survival = 40%

Slide 31

Endometrial Carcinoma Peak age: 55-65 (not before 40) Frequently arises in endometrial hyperplasia Risk factors: obesity, nulliparity, estrogen replacement Symptoms: leukorrhea, irregular bleeding Metastasizes late

Slide 34

Surface epithelial tumors Cystadenoma Cystadenocarcinoma Germ cell tumors Teratoma Dysgerminoma Yolk sac tumor Choriocarcinoma Granulosa-theca cell tumor Sertoli-Leydig cell tumor Sex cord-stromal tumors Origin of Ovarian Tumors

Slide 35

Cystadenoma Benign tumor derived from surface epithelium Repeated ovulation, scarring, infolding of epithelium leads to cysts, which can undergo neoplastic transformation Typically large, occasionally bilateral

Slide 40

Slide 41

Teratoma Benign tumor with differentiation along all three germ cell layers (ectoderm, endoderm, mesoderm) Usually cystic, with skin inside (dermoid cyst) Sebaceous material, matted hair, teeth, bone Malignant variant has immature tissues

Slide 44

Ovarian Cancer 22,000 new cases / 14,000 deaths predicted in 2014 5 th commonest, 5 th most deadly cancer in women Danger: no definitive signs until advanced Peak age: 50 Most are cystadenocarcinomas

Slide 45

Papillary cystadenocarcinoma

Slide 46

Slide 47

Ovarian Cancer Symptoms Feeling of fullness or bloating Pelvic pain Back pain Abnormal menses Risk factors Nulliparity Family history (BRCA gene mutation) NOT using oral contraceptives!

Slide 48

Ovarian Cancer Treatment: surgery, radiation, chemotherapy Prognosis depends on stage Cancer confined to the ovary: 5y survival 70% Cancer through ovarian capsule: 5y survival 13%

Female Reproductive System Outline Cervix Uterus Ovaries Breast Fibrocystic change Tumors

Slide 50

Breast Many breast diseases present as lumps Most lumps represent benign things but a lump always needs to be evaluated Ultrasound, mammography, fine needle aspiration, and biopsy are the usual methods

Slide 51

Most breast lumps are benign

Slide 52

Fibrocystic Change Two kinds: nonproliferative and proliferative change Cause: exaggeration of normal breast cycles Rarely associated with increased cancer risk Very common (present in most women at autopsy) Called fibrocystic change, not fibrocystic disease

Slide 53

Fibrocystic Change Nonproliferative fibrocystic change Increased stroma Dilation of ducts, formation of cysts Proliferative fibrocystic change Hyperplasia of breast epithelium If epithelium shows atypia, 5x risk of cancer

Breast Carcinoma 233,000 new cases / 40,000 deaths predicted in 2014 Most common, 2 nd deadliest cancer in women Lifetime risk: 1 in 8 75% of patients are >50 Rate was increasing but now stable

Slide 62

Breast Carcinoma Risk Factors Age Family history Increased estrogen exposure Obesity Alcohol consumption High-fat diet

Slide 63

Breast Carcinoma Family History 5-10% of all cases are hereditary Worry if first degree relative with breast cancer Most have BRCA-1 or BRCA-2 mutations Tumor suppressor genes; help repair DNA Genetic testing difficult Most carriers get cancer by age 70

Slide 64

Breast Carcinoma Clinical Findings If discovered by palpation Solitary, painless, moveable mass 2-3 cm in diameter Axillary nodes positive in 50% of patients If discovered by mammography 1 cm in size Axillary nodes positive in only 15% of patients As disease progresses Fixation to chest wall Adherence to overlying skin Peau dorange
