Abstract
The autopsy findings of 100 patients who had a resection for large bowel cancer and who were classified by a clinicopathologic staging system were analyzed. Seventy patients had carcinoma at autopsy. The value of this method of staging was assessed by relating the stage at operation to these findings. Foryt-five per cent of early stage tumors (A or B) had metastases. If the detection rate of occult metastases could be improved for stage A and B tumors, this might increase the prognostic accuracy of this staging system.
