title: The influence of age upon the survival after curative operation for colorectal cancer.
abstract: From 1962 to 1982 1,623 consecutive patients were curatively operated for colorectal adenocarcinoma. For all patients cancer specific mortality rates were registered and the influence of the following prognostic factors was evaluated: tumour stage and grade, adenomas, age, sex and tumour site. In a multivariate Cox analysis, with backward elimination of non-significant factors at a 10% level, Dukes' C stage, poor differentiation, and age between 40 and 60 years at onset of carcinoma reached independent prognostic significance.
