Hypofractionated External Beam Radiotherapy With Adaptive Planning for Endometrial and Cervical Cancers
NCT06538337
Recruiting
After surgery to remove the main endometrial and/or cervical tumor, most women receive radiation therapy. This study uses hypo-fractionated radiation therapy, which is a type of radiation therapy in which the total prescribed dose of radiation is delivered in fewer but larger doses than conventional or standard radiotherapy. This research study aims to determine if hypo-fractionated radiation therapy given after surgery can improve treatment tolerability (i.e., fewer treatments) with comparable... Read More
