Mortality rates from the Large Bowel Cancer Project are presented with special reference to patients older than 70 years. The in-hospital mortality rate among those who underwent curative resection for colorectal carcinoma was 7%. Unlike long-term prognosis, which is influenced by pathological features, in-hospital mortality is influenced largely by clinical factors. Age was an adverse factor (78% of deaths occurred among those aged over 70, who formed 46% of the study population), as was obstruction or perforation. 55% of deaths were due to cardiopulmonary complications. Educating patients to seek treatment early, careful preoperative assessment and postoperative monitoring of cardiopulmonary function, and, in selected patients, use of local treatments rather than wide resections may help to reduce mortality in elderly patients.
