Clinical trials

This is an investigator-initiated, prospective, national multi-center, phase III, randomized, open-label, non-inferiority clinical study. The hypothesis is that using online adaptive radiotherapy technology for moderately fractionated radiotherapy in post-operative patients with cervical/endometrial cancer may reduce radiotherapy-related toxicity and improve quality of life while ensuring target coverage. The objective is to evaluate treatment-related toxicity and efficacy of moderately fractionated online adaptive radiotherapy compared to conventionally fractionated intensity-modulated radiotherapy in post-operative cervical and endometrial cancer patients, aiming to provide a more precise, convenient, and cost-effective treatment option for patients.

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.
