Hormonal therapy in chronic radiation colitis

Severe gastrointestinal bleeding is a rare complication of radiation therapy that requires frequent transfusions. This case report describes a patient with severe bleeding from radiation colitis after treatment of bladder cancer. During 5 months of therapy with multiple drugs, the patient needed 26 units of packed red cells. A subsequent hormone therapy consisting of an estrogen-progesterone combination significantly reduced the need for blood transfusions and hospitalization. We conclude that hormones might provide a promising new additional symptomatic therapy for bleeding radiogenic colitis.
