A Comparison of Acute Toxicities Between Patients Treated With Protons or Intensity-Modulated Radiation Therapy for Post-Operative Treatment of Endometrial or Cervical Cancers
This early phase I trial compares the side effects between patients treated with proton radiation therapy versus intensity modulated radiation therapy after surgery for the treatment of endometrial or cervical cancer. Radiation therapy uses high energy protons or x-rays to kill tumor cells and shrink tumors. Using quality of life questionnaires and adverse event assessments may help doctors learn whether proton radiation therapy is associated with lower acute gastrointestinal toxicities at the end of treatment compared to intensity modulated radiation therapy in patients with endometrial or cervical cancer.
