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

If you participate in this research, you will receive radiation therapy guided by MR imaging. This will involve daily radiation treatments that may be adjusted based on imaging taken at each session (known as adaptive radiotherapy). This approach is considered investigational as it is not yet a standard treatment for endometrial cancer.
Your participation in the study will involve approximately 15 treatment sessions over about 3 weeks. Each session may take longer than standard radiation treatments because imaging and treatment planning are performed on the same day.

研究组 & 干预措施
Experimental: MR-guided Adaptive Pelvic IMRT
Participants receive moderately hypofractionated MR-guided adaptive pelvic intensity-modulated radiation therapy (IMRT) delivered via MR-linac to a total dose of 42 Gy in 15 fractions with daily onboard MRI and online adaptive replanning as needed to optimize target coverage and minimize radiation exposure to surrounding organs at risk. Vaginal brachytherapy may be administered following IMRT at the treating physician's discretion per institutional standards.
