Endometrial Cancer Screening (PDQ®)–Health Professional Version

SECTIONS

Summary of Evidence

Separate PDQ summaries on Endometrial Cancer Prevention; Endometrial Cancer Treatment; and Uterine Sarcoma Treatment are also available.

Transvaginal Ultrasound

Benefits

There is no evidence that screening by ultrasonography (e.g., endovaginal ultrasound or transvaginal ultrasound) reduces mortality from endometrial cancer. Most cases of endometrial cancer (85%) are diagnosed at low stage because of symptoms, and survival rates are high.

Harms

Based on solid evidence, screening asymptomatic women will result in unnecessary additional biopsies because of false-positive test results. Risks associated with false-positive tests include anxiety and complications from biopsies.

Study Design: Evidence obtained from cohort studies.
Internal Validity: Fair.
Consistency: One study for endometrial biopsy and one study for hysteroscopy.
Magnitude of Effects on Health Outcomes: Small negative magnitude.
External Validity: Fair.

Endometrial Sampling (Biopsy)

Benefits

There is inadequate evidence that screening by endometrial sampling (i.e., biopsy) reduces mortality from endometrial cancer. Most cases of endometrial cancer (85%) are diagnosed at low stage because of symptoms, and survival rates are high.
