1. Study Type: Single-center, single-arm, prospective study.
2. Sample Size: 20 patients with high-risk endometrial cancer were enrolled.
3. Treatment Procedure:
The existing clinical oART (Online Adaptive Radiotherapy) workflow protocol for malignant tumors used in our department was applied.
Procedures included simulation, target volume delineation, radiotherapy planning, and treatment delivery.
External beam radiation therapy (EBRT) was delivered using moderate hypofractionation.
If indicated, brachytherapy was performed after the completion of EBRT. When combined with chemotherapy, radiotherapy could be administered during chemotherapy intervals or after completion of chemotherapy.
4. Study Endpoints:
Primary Endpoint: Incidence of acute toxicity. Secondary Endpoints: 3-year failure-free survival (FFS) rate, incidence of chronic toxicity, quality of life (QoL), treatment costs, etc.
