Hypofractionated External Beam Radiotherapy With Adaptive Planning for Endometrial and Cervical Cancers (HERA Trial)
Jonsson Comprehensive Cancer Center
Summary
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 side effects. Participants will be in the study for about 5 years: Radiation therapy: * 5 daily treatment sessions of MRI or CT-Guided Stereotactic Body Radiation Therapy (SBRT). * Each treatment session will occur on a weekday (typically consecutive weekdays) and will last approximately an hour. Treatment Follow-Up: * Check-up Appointment and answer questions at 3 months post RT * Check-up Appointments with physical exam every 6 months (+/- 4 weeks) for up to 5 years.
Description
The investigators hypothesize that adaptive planning with either computed tomography (CT) or magnetic resonance imaging (MRI) guidance may offer improved SBRT plans for postoperative gynecological cancer patients due to issues with anatomic variation between and during fractions of radiation therapy. Treatment on an MRI-guided linear accelerator with adaptive planning capabilities has been shown to significantly improve acute toxicity in the setting of prostate SBRT compared to conventional linear accelerators.10 The investigators, therefore, propose using adaptive planning with CT- or MRI-gui…
