An analysis is presented of 2313 histologically proven cases of carcinoma of the colon and rectum at Charity Hospital from January 1, 1948 through December 31, 1970. For the 2010 cases diagnosed prior to January 1, 1968, so that 5-year followup was possible, survival curves based upon several parameters were determined. Dukes' classification, histologic confirmation of lymph node involvement, and the surgeon's classification of the operation as curative or palliative were the factors that had the greatest influence on survival. The 5-year survival rate for the entire series was 24%. This figure is increased to 47% for those undergoing a curative procedure. The lesion is more common in females than males, and Caucasians than Negroes. In this large series there is a negligible difference in survival between the male and female populations or between the Negro and Caucasian populations.
