Screening of chronic radiation proctitis and colorectal cancer using periodic total colonoscopy after external beam radiation therapy for prostate cancer

ConclusionsThe high detection rate of asymptomatic radiation proctitis suggests the utility of total colonoscopy to screen for early-stage colorectal cancer prior to or following radiotherapy for prostate cancer. Considering the longevity after localized prostate cancer treatment, the awareness of chronic radiation-induced proctitis and the risk of colorectal cancer masked by bleeding is needed in treatment decision -making.
