Stage Classification is a short description of a cancer at a point in its natural history, and should have significance in guiding treatment, in prognosis, and in comparison of end results. The clinical, surgical‐evaluative, and post‐treatment classifications are defined and the TNM System described. A retrospective study of 566 cases of carcinoma of the colon identified the features significant in survival. Most important were degree of colonic penetration of the cancer, local lymphatic and blood vessel invasion, regional node involvement, histologic differentiation, and distant metastases. Comparison is made to the Dukes Classification. A similar study of 580 cases of carcinoma of the rectum identified the significant features of location, extension beyond rectum, local lymph node involvement, and distant spread. The application of the findings to a TNM Staging System is discussed.
