title: Necrotizing colitis in patients with cancer.
abstract: Necrotizing lesions of the colon occur in patients with malignancy. We identified 26 patients with cancer (23 with acute leukemia and three with solid tumors) who died from necrotizing colitis. Autopsies revealed three pathologic categories: pseudomembranous colitis in 69 per cent, agranulocytic colitis in 19 per cent and ischemic colitis in 12 per cent. Most died from sepsis. A comparison of characteristics was made with a control population matched for diagnosis, age, cause of death and duration of neoplasia. Nearly all patients in both groups had fever and were granulocytopenic secondary to chemotherapy. Most received antineoplastic and antimicrobial regimens during the month prior to their terminal illness. Abdominal pain and distention, stomatitis and necrotizing pharyngitis were frequently associated with colitis. Hyperbilirubinemia was a frequent late complication in those with colitis and the control group. Single and multiorganism septicemia were found more frequently in patients with colitis. As antemortem diagnosis was unusual, aggressive attempts at diagnosis are necessary to assess the true incidence of this disorder and the best therapy.
