[Value of preoperative risk factors in patients with resectable esophageal cancers].

Since 1. 1. 1964 245 patients with oesophageal carcinoma underwent resection at the department of surgery of the university of Cologne. A significant correlation between stage, localisation or type of carcinoma and the postoperative mortality was not found. It was possible to develop organ specific scores which were able to detect groups of patients with a high postoperative mortality, but the predictive value of these scores was too small for relevant clinical decision making.
