? Objective To explore the rational extent resected in operation for low level rectum cancer to decrease the recurrence rate.Methods Of 147 cases of low rectum cancer including 99 cases were reserved anus and 68 cases underwent Mile′s operation. Results The 3 year survival rate was 72.1%(93 cases)and the 5 year survival rate was 63.4%(71 cases).The recurrence rate was 28.9%(42 cases),which was related to the pathological types and Duke′s stage, not to the operation method.Conclusions The low rectum cancer of Duke′s B or Duke′s C,which presents high malignance, should undergo extended radical operation.Those the distance of lower edge to the dentate line is more than 3～4cm should reserve anus as much as possible and the extended radical operation is key to reducing its recurrence rate. 〔
