Endometrial Neoplasia
Endometriosis
ectopic endometrial glands / chocolate cysts / 1st - ovaries (associated w/ endometrioid
carcinoma) / 2nd recto-vaginal septum / reproductive age / dysmenorrhea, menometrorrhagia, dyspareunia, infertility / pathogenesis: retrograde menstruation, implantation, coelomic metaplasia, lymphatic, hematogenous dissemination
Endometrial hyperplasia
simple: dilated glands, abundant stroma
complex: crowded architecture, epithelium may be stratified, reduced stroma
atypical simple or complex: 25% progress to carcinoma
other endometrial CA usually has worse prognosis
adenosquamous, clear cell carcinoma, squamous carcinoma, papillary serous carcinoma
Endometrial Adenocarcinoma
most common invasive neoplasm of female genital tract / 75% of endometrial CA
70% before age of 50 / peak 60 yrs
Presentation: post-menopausal bleeding (90%), abnormal Pap (30%), bone pain
Note: if endometrial biopsy (90% sensitivity) negative, proceed with hysteroscopy
Risk factors: unopposed estrogen, obesity, nulliparity, low parity, anovulation, menopause > 50 yrs / diabetes, hypertension, breast/ovarian cancer, family history of endometrial cancer
Type I pre and peri-menopausal, low grade, hyperplastic, secretory, responds to HRT, whites
Type II post- menopausal, high grade, serous clear cell, progressive, does not respond to HRT, blacks
endometrioid: most common / adenocarcinoma / may have squamous differentiation
Method of Spread: direct extension, lymphatic (most), direct, peritoneal seeding, hematologic dissemination
Treatment: TAH/BSO with surgical staging +/- postoperative radiation, hormonal therapy, single-agent chemotherapy / hormonal therapy for advanced/recurrent
Prognosis: histological grade is the most important factor, then depth of myometrial invasion (> 1/3 worse), then histological type / pelvic node mets, tumor volume, involvement of cervix/adnexa, positive peritoneal washings
Overall 5 yr survival is 65% / stage I (73%), stage II (56%), stage III (32%), stage IV(10%) / 75% of recurrence in first 2 yrs, 85% in first 3 yrs
FIGO Grading I - III / increases with solid component / FIGO Staging I – IV is most common / abdominal abscesses is most common COD
Follow-up: every 3 months for 2 yrs, then every 6 months for 3 yrs, then once yr

most common uterine neoplasm / SMC / blacks > white / usually multiple / hyaline fibrosis / apoplectic leiomyoma: pregnancy, progestins / hemorrhage, edema, myxoid changes, mitoses apoplectic and marantic: hemorrhagic degeneration/necrosis due to hormonal effects
Treatment: OCP’s, NSAIDS, surgery
Malignant Mixed-Mullerian Tumor (MMMT) – poor prognosis
1st uterine sarcoma / associated with pelvic radiation / homologous or heterologous (muscle, cartilage, bone, fat) / rapid spread, poor prognosis for both types
Leiomyosarcoma
2nd uterine sarcoma / mitotic and cellular atypical / not arising from leiomyoma
Treatment: only proven treatment is surgical

Pathology: endometrium may be secretory (Arias-Stella) or normal appearing
Treatment: laparoscopy, laparotomy or methotrexate if small/unruptured / single dose MTX (84%
success rate) or multiple dosing regimen / with leucovorin rescue
