Large bowel cancer: a retrospective study of 635 cases.

A retrospective survey of 635 cases of large bowel cancer treated at the Princess Alexandra Hospital, Brisbane, from 1956 to 1970 is presented. The age and sex incidence, presentation and pathology are discussed, and a detailed analysis is made of treatment and operative mortality rates. The resectability rate was 72-2%; the operative mortality rate for resectable colonic lesions was 6-6%, and for resectable rectal lesions, 7-3%. There was an operative mortality rate in the presence of acute obstruction of 17-5%. This study forms the basis of a prospective survey presently being undertaken at the Princess Alexandra Hospital.
