Overview
There is insufficient evidence to recommend routine screening for radiation proctitis however recent studies shows that the impairment of the rectum's ability to heal may predispose other organs, exposed to the same high radiation doses, at high risk of malignant transformation so It has been suggested that patients exposed to higher doses of radiation may need to be more closely screened for other malignancies but further studies need to be conducted before definitive recommendations can be made.[1]The risk of second cancer after irradiation, although probably small, needs nevertheless to be carefully monitored.[2]
Screening
There is insufficient evidence to recommend routine screening for [disease/malignancy].
Pelvic radiation therapy is associated with an increased rate of rectal cancer. The latency period between radiation exposure and development of a radiation- induced cancer is felt to be at least 5 years. For this reason it is important for anyone who has received pelvic radiation to have either a colonoscopy or a flexible sigmoidoscopy starting 5 years after completion of radiation therapy."Radiation Proctitis".
