Tumour site: a prognostic factor in colorectal cancer? A multivariate analysis

Data from 753 patients with single adenocarcinomas of the large intestine diagnosed and treated at Trondheim Regional and University Hospital between 1964 and 1978 were studied to determine the influence of tumour site on survival by adjusting for tumour stage, age, and sex. The Cox regression model was used. Although the clinicopathologic stage had the strongest association with prognosis, the tumour site independently influenced the mortality, which increased from the right colon via the transverse/left part of the colon to the rectum.
