PARTIQoL: Proton Therapy vs. IMRT for Low or Intermediate Risk Prostate Cancer


The purpose of this study is to compare two types of radiation therapies called Intensity Modulated Radiation Therapy (IMRT) and proton beam therapy (PBT) as treatments for prostate cancer.


Participants will still have standard of care, such as consulations, scans and other procedures. You will be asked to come back for follow-up at various time points. Participants will be put into the IMRT group or the PBT group. Follow-up visits will occur at 3, 6, 9, 12, 18, 24, 36, 48, and 60 months (and longer follow-up as per routine care).
