COMPPARE: A Path to Improve Future Health Outcomes for Men with Prostate Cancer

Thank you for your interest in the COMPPARE study.

COMPPARE stands for “A Prospective COMparative Study of Outcomes with Proton and Photon RAdiation in PRostate CancEr (COMPPARE).”

This study is funded by the Patient-Centered Outcomes Research Institute (PCORI) and led by Dr. Nancy Mendenhall at the University of Florida.

About the study

COMPPARE will ask 3,000 prostate cancer patients (ages 30-80) across the US who have chosen to be treated with proton therapy or photon therapy to answer brief surveys regarding treatment choice, quality of life, and side effects for at least 3 years.

To participate, talk to your doctor about the study.
