Shorter radiation after hysterectomy shows promise for endometrial cancer
NCT ID NCT04386993
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a shorter course of pelvic radiation (about 1 week instead of the usual 5-6 weeks) given after hysterectomy for advanced endometrial cancer. The goal was to see if this shorter treatment causes fewer side effects while still controlling the cancer. The study included 25 women with stage III-IVA endometrial cancer or certain high-risk types. Researchers measured side effects and quality of life to see if the shorter radiation is safe and effective.

Inclusion Criteria: * Histologically or cytologically confirmed stage IIIA-IVA endometrial cancer, or any stage I-IVA where any proportion of the tumor is uterine serous, clear cell, de-differentiated, or carcinosarcoma histology. * Must have already undergone radical hysterectomy. Hysterectomy may have occurred no more than one year prior to enrollment. * At least 18 years of age. * ECOG performance status ≤ 2 * Minimal bone marrow and organ function as defined below: * Leukocytes ≥ 1,000 cumm * Absolute neutrophil count ≥ 500 cumm * Platelets ≥ 50,000 cumm * Hemoglobin ≥ 7g/dL * Ability to understand and willingness to sign an IRB approved written informed consent document (or that of legally authorized representative, if applicable). Exclusion Criteria: * Prior radiation to the pelvis. * Currently receiving any investigational agents. * Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, inflammatory bowel disease, or irritable bowel disease. * Patients with HIV are eligible unless their CD4+ T-cell counts are \< 350 cells/mcL or they have a history of AIDS-defining opportunistic infection within the 12 months prior to registration. Concurrent treatment with effective ART according to DHHS treatment guidelines is recommended.
