Study of Pelvic Hypofractionated Radiotherapy in Endometrial Cancer
Endometrial Cancer
About this trial
This is an interventional treatment trial for Endometrial Cancer
Eligibility Criteria
Inclusion Criteria:
- Diagnosis of endometrial cancer with any of the following primary histologic types: endometrioid, papillary serous, clear cell, carcinosarcoma, or mixed epithelial histologies.
- Age ≥ 18 years.
- Must have been diagnosed with Stage I-III disease according to The International Federation of Gynecology and Obstetrics (FIGO).
- Must have been treated with definitive intent, including standard-of-care hysterectomy, without any gross residual disease post-operatively. Nodal dissection is not required, but if it is not performed, then diagnostic imaging to confirm absence of gross pelvic or para-aortic disease should be obtained pre- or post-operatively.
- Recommended to undergo whole pelvic radiotherapy without concurrent chemotherapy or para-aortic radiation. Chemotherapy before or after radiotherapy is acceptable.
Exclusion Criteria:
- Distant metastases as determined clinically or radiographically based upon standard-of-care work-up for endometrial cancer.
- Concurrent (or other) chemotherapy occurring at the time of study.
- Gross residual disease (cancer cells that remain after attempts to remove the cancer have been made) post-operatively and/or at the time of radiation based upon pre-op or post-op imaging, intra-operative findings, and gynecologic oncologists' judgment.
- History of small bowel obstruction, inflammatory bowel disease, irritable bowel syndrome, connective tissue disorder requiring ongoing active medical management, or prior radiation therapy directed to the pelvis.
- Unresolved chemotherapy-associated diarrhea or abdominopelvic pain requiring medication prior to the initiation of radiation.
- Recommendation to undergo para-aortic nodal irradiation.

Hypofractionated Radiation Treatment (Dose-Finding Arm)
Expansion Cohort (Efficacy Arm)
All study participants in this arm will receive hypofractionated whole pelvic radiation treatment for a shortened time period of 3-5 weeks. The goal of this arm is to establish a safe and tolerable dose of shortened (hypofractionated) pelvic radiation treatment for study participants. Once a safe and tolerable dose is established for this shortened form of radiation treatment, participants who meet criteria for the second phase of this study will participate in an expansion cohort that will explore the efficacy (how effective shortened/hypofractionated radiation treatment is for treating endometrial cancer).
Participants in this arm will test how effective hypofractionated/shortened whole radiation treatment is ("efficacy") at the dose established in the first phase of this study by following up with their doctors to report their current health status and symptoms during clinical visits. Participants will return for routine clinical follow-up approximately 1 month following radiation, then at 3 months following radiation, then every 3 months for the next 2 years following treatment.
