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
Mesenchymal Tumors of Endometrium
Leiomyoma

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
Gestational Trophoblastic Tumors
Complete hydatidiform mole (CHM)

homozygous 46 XX (started as one paternal X / RF: young/old, Asian, FH, infertility, smoking large edematous villi (grapes of wrath) / Symptoms: vaginal bleeding, preeclampsia, uterine enlargement, high hCG complications: DIC, infection, choriocarcinoma (2%)


Partial hydatidiform mole (PHM)

fetal tissue often present / triploidy (69XXY) results from dispermy / RF’s same as CHM

w/out maternal age, ace / milder symptoms / does NOT lead to choriocarcinoma
Choriocarcinoma poor prognosis

mole, abortion, normal pregnancy / no chorionic villi / Treatment: chemotherapy


Placental site trophoblastic tumor (PSTT)

rare / intermediate trophoblast deeply invades myometrium


Miscellaneous
Endometrial stromal tumors

Cause of 9% of maternal deaths from exsanguinations / commonly rupture by 12th week



Risk factors: prior ectopic, chlamydia (PID), tubal surgery, smoking, increasing age

Diagnosis: absence of IUP (ultrasound) and positive B-hCG (< 6000) / transvaginal ultrasound 85% sensitive for IUP at 6-7 wks or B-hCG over 1500 / confusing factors: multiple gestations, failed IUP, obesity, fibroids, uterine axis

Labs: normal hCG increase is 66% or more per/48 hrs (15% of normal IUP have lower bhCG) / 17% of ectopics have normal hCG doubling time / doubling rate at 6-7 wks is every 3.5 days

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



Absolute contraindications: breastfeeding, immunodeficiency, alcoholism, alcoholic liver disease, chronic liver disease, blood dyscrasias (bone marrow hypoplasia, leukopenia, thrombocytopenia, severe anemia), known sensitivity to MTX, active pulmonary disease, peptic ulcer disease, hepatic, renal, hematologic dysfunction

Relative contraindications: gestational sac > 3.5 cm / embryonic cardiac motion

Note: pt must avoid alcohol, folate, NSAIDS, sexual intercourse during treatment



Precautions: get LFT, U/A, transvaginal ultrasound within 48 hrs of treatment,

Treatment Success: increase in hCG during 1st 1-3 days of treatment, vaginal bleeding/spotting, 2/3 will have increasing abdominal pain

Treatment Failure: severely worsening abdominal pain, hemodynamic instability, hCG does not decline by at least 15% between day 4 to 7 / increase or plateau of B-hCG after 1st week
Ovary

continued progesterone secretion / large luteinized granulosa cells / smaller theca lutein cells

involution of CLC usually leads to corpus albicans cyst
Polycystic Ovaries (PCOD) (Stein-Leventhal) (merge with other)

present in 20s with oligomenorrhea, menometrorrhagia, infertility (amenorrhea), and hirsutism (androstenedione to testosterone), acanthosis nigricans / bilaterally enlarged ovaries / thick, fibrotic cortical tunica / cystic follicles / hyperplasia and luteinization of theca interna w/out CL formation
