  • Title: Chronic ulcerative colitis and colon cancer: can radiographic appearance predict survival patterns?
    Author: James EM, Carlson HC.
    Journal: AJR Am J Roentgenol; 1978 May; 130(5):825-30. PubMed ID: 417578.
    Abstract:
    Twenty-four patients with chronic ulcerative colitis and colon carcinoma who underwent barium enema examination prior to the diagnosis of cancer were studied in an attempt to correlate the radiographic appearance of the tumors with their biologic behavior, as well as to assess the accuracy of the barium enema in detection. Of the radiographically detected tumors, 65% displayed an annular infiltrative appearance, with the prime radiographic manifestation being relative nondistensibility of the involved segment. The remaining tumors had various appearances more typical of noncolitic colon cancer. Patients with infiltrative lesions had a much poorer prognosis than those with noninfiltrative lesions. Of 33 gross tumors described pathologically and/or surgically, only 70% were correctly detected by barium enema. It is suggested that periodic barium enema examinations are an unreliable means of following patients with ulcerative colitis if malignant degeneration is to be detected at an early and curative stage. Prophylactic proctocolectomy may be the best therapeutic approach.
