Study Details

Brief 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.
