✦ Synopsis

Carcinoma of the endometrium is the most common gynecologic malignancy, expected to account for 33,000 new cases and 6,000 deaths in 1995. Most endometrial cancers occur in postmenopausal women and produce abnormal vaginal bleeding. Some women exhibit the premalignant changes of atypical endometrial hyperplasia before developing an overt carcinoma. Identified epidemiologic risk factors include obesity, diabetes mellitus, use of unopposed exogenous estrogens, estrogen-secreting tumors, and a reproductive history characterized by prolonged estrogenic predominance. Diagnosis can be readily established by outpatient endometrial biopsy. Because clinical estimates of disease extent and spread are subject to substantial error, endometrial cancer is now a surgically staged neoplasm. A well-defined set of surgicopathologic risk factors have been incorporated into the staging scheme. Women with extrauterine disease comprise about 20% of cases and are at greatest risk for tumor recurrence and death from disease. Within the much larger group of women whose tumors are limited to the uterus, recurrence risk can be stratified by cytologic grade, cell type, depth of myometrial invasion, and extension to the cervix. About two-thirds of women have low-risk disease confined to the uterus when these criteria are employed, while the remaining one-third have high-risk subtypes. Recent areas of investigation have focused on molecular and genetic markers. Two clinical observations currently being examined are the poorer survival of Black women with uterine cancer and the apparent association of endometrial lesions with chronic tamoxifen suppression in women with breast carcinomas.
