Obstructive and perforative colonic carcinoma: patterns of failure.

Published

Journal Article

Carcinoma of the colon complicated by obstruction or perforation has been recognized as having a poorer prognosis than tumors without obstruction or perforation. To clarify the natural history, failure patterns, and implications for adjuvant treatment after resection with curative intent, a review of the recent Massachusetts General Hospital (MGH) experience was undertaken. From 1970 to 1977, 77 patients with obstructive colonic carcinoma and 34 patients with localized perforation at the tumor site were identified and compared with a control group of 400 patients without obstruction or perforation undergoing curative resection. All patients were observed for a minimum of five years or until the patient's death. The actuarial five-year survival and disease-free survival rates in patients with obstruction was 31% and 44%, respectively, in contrast to 59% and 75% in control patients. For patients with localized perforation, the five-year actuarial survival and disease-free survival rates were 44% and 35%, respectively. Of the 77 patients with obstructing tumors, 32 patients (42%) developed local failure--nine with local failure only and 23 patients with local failure and distant metastases. Thirty-four patients (44%) developed distant metastases. Fifteen (44%) patients of 34 with perforative colonic carcinoma had local failure. Distant metastases occurred in 15 patients (44%). The incidence of local failure and distant metastases in the control group was 14% and 21%, respectively. The rate of local failure and distant metastases increased with stage and was generally higher stage for stage than in the control group.(ABSTRACT TRUNCATED AT 250 WORDS)
