Endometrial cancer is a common malignancy, usually an adenocarcinoma.
Overweight and obesity are associated with an increased incidence and poorer outcome.
Patients typically present with postmenopausal vaginal bleeding and often have surgically curable disease.
Diagnosis is confirmed by biopsy, or dilation and curettage; staging and histology is confirmed at surgery.
The most important prognostic information relates to stage, histologic subtype, tumor grade, patient age, presence of lymphovascular space invasion, and extent of cervical and myometrial invasion.
Adjuvant vaginal brachytherapy or pelvic external beam radiation therapy can reduce local recurrence and improve progression-free survival, but does not improve survival in stages I and II disease.
Chemotherapy and chemoradiotherapy are options for patients with stages III and IV disease. The optimal role of chemotherapy in patients with recurrent disease or nonendometrioid carcinomas (e.g., serous, clear-cell, undifferentiated carcinoma, carcinosarcoma) is unclear and controversial.
An epithelial malignancy of the uterine corpus mucosa, usually an adenocarcinoma.
History and exam
Key diagnostic factors
- postmenopausal vaginal bleeding (PVB)
Other diagnostic factors
- uterine mass, fixed uterus, or adnexal mass indicating extrauterine disease
- abnormal menstruation or vaginal bleeding in a premenopausal woman
- pain (abdominal or pelvic) and weight loss
- symptoms of metastatic disease
- signs of metastatic disease
- overweight and obesity
- age >50 years
- endometrial hyperplasia
- unopposed endogenous estrogen
- unopposed exogenous estrogen
- tamoxifen use (postmenopausal women)
- insulin resistance
- family history of endometrial cancer
- family history of breast cancer or ovarian cancer
- family history of hereditary nonpolyposis colorectal cancer (Lynch syndrome)
- family history of PTEN syndromes
- nulliparity and infertility
- polycystic ovary syndrome
- radiation therapy
- white ethnicity
1st investigations to order
- pelvic (transvaginal) ultrasound
- office-based endometrial biopsy (with or without office-based hysteroscopy) and histopathology
- hysteroscopy, dilation and curettage (D&C), and histopathology
- Pap smear
Investigations to consider
- serum CA-125 level
- saline infusion sonohysterogram
- BUN and creatinine (renal function testing)
- chest x-ray
- CT scan of chest, abdomen, and pelvis
- MRI of uterus, pelvis, and abdomen
- PET/CT scan
stage IA endometrioid carcinoma not considering fertility preservation
stage IA endometrioid carcinoma considering fertility preservation
stage IB or II endometrioid carcinoma
stages III to IV endometrioid carcinoma; all nonendometrioid carcinomas (high risk)
recurrent or incurable disease
