Toxicity after 125I prostate brachytherapy in patients with inflammatory bowel disease

Twenty-three percent and 15% patients with IBD experienced Grade 3 or higher acute and late GI toxicity, respectively, after brachytherapy. Prostate brachytherapy should be used with great caution or avoided, particularly for men with active IBD involving the rectum. Biopsies of the rectum after brachytherapy should be avoided as it may lead to ulceration.
