Adaptive Daily MR-Guided Adjuvant Pelvic Therapy-Endometrial Cancer

Rutgers, The State University of New Jersey

Start Date

6/9/2026

Completion Date

6/1/2029

Summary

To evaluate the safety, tolerability, and preliminary efficacy of moderately hypofractionated (15-fraction) MR-guided adaptive pelvic IMRT in patients with endometrial cancer.

Detailed Description

The purpose of this research study is to evaluate a new way of delivering radiation therapy for patients with endometrial cancer. This study will test a shorter course of radiation treatment using magnetic resonance (MR)-guided technology, which allows for more precise targeting of treatment areas. The goal is to determine whether this approach is safe, well-tolerated, and effective, while potentially reducing side effects and the overall time required for treatment. If you take part in the research, you will receive radiation therapy using MR-guided imaging. This involves daily radiation treatments that may be adjusted based on imaging taken at each session (called adaptive radiotherapy). This approach is considered investigational because it is not yet a standard treatment for endometrial cancer. Your time in the research will take Your participation in the study will involve approximately 15 treatment sessions over about 3 weeks. Each session may take longer than standard radiation treatments due to the imaging and treatment planning performed on the same day.The purpose of this research study is to evaluate a new method of delivering radiation therapy for patients with endometrial cancer.

Eligibility Criteria

Age Range: 18 years to 90 years

Inclusion Criteria: 1. Histologically confirmed endometrial carcinoma (endometrioid, serous, clear cell, carcinosarcoma, or dedifferentiated histology). 2. Indication for adjuvant pelvic radiotherapy (± vaginal brachytherapy) for HIR defined by the ASTRO guidelines and GOG-99(7, 9) : 3. Age 4. High-grade histology (grade 2-3) 5. Depth of myometrial invasion 6. LVSI 7. Positive pelvic nodes 8. Cervical stromal invasion 9. Presence of poor prognostic molecular markers 10. Age ≥18 years. 11. Ability to provide informed consent. 12. Eligible to receive adjuvant systemic therapy, if indicated, with a minimum 3-week interval between chemotherapy and radiotherapy. 13. Willing and able to complete EORTC QLQ-C30 and EN-24 questionnaires in a validated language version. Exclusion Criteria: 1. Prior pelvic radiotherapy. 2. Contraindication to pelvic radiotherapy (e.g., active connective tissue disorder or inflammatory bowel disease). 3. Presence of a hip prosthesis that would compromise treatment planning or delivery. \-
