IBD patients with prostate cancer may benefit from radiation therapy

Key clinical point: Treatment with radiation therapy is safe and effective for men with prostate cancer and underlying inflammatory bowel disease, with no biochemical relapses during an early follow-up period. 

Major finding: With a median time of 22 months to any GI toxicity, one IBD patient experienced a high-grade toxicity (grade 3 proctitis) and 3 patients reported hemorrhoidal flares as the most common low-grade toxicity.

Study details: The data come from an institutional database of 4245 men who underwent stereotactic body radiation therapy for prostate cancer, including 31 patients with underlying inflammatory bowel disease.

Disclosures: The study was supported in part by a grant from Accuray. The researchers had no other financial conflicts to disclose.
