Factors influencing survival with complete obstruction and free perforation of colorectal cancers

Abstract

A review of 26 years' experience in the management of patients with obstruction and perforation of the colon due to carcinoma at Hôpital Notre-Dame, Montréal, is reported. We try, in the present paper to identify the factors responsible for the very poor prognosis in complete obstruction and free perforation of colorectal cancers. As we are comparing these complicated cancers with a larger group of uncomplicated cancers, our results are analyzed by the chi-square test.
