Purpose : The purpose of this study was to evaluate the oncologic outcome of patients with adenocarcinoma of the colon and rectum who underwent resection for carcinoma by one surgeon.

Materials and Methods :During the study period from May 1996 to July 2005 , 477 consecutive patients with colorectal cancer treated operatively at the Kwang-tien General Hospital(with newly diagnosed adenocarcinoma of the colon and rectum) were prospectively studied.Surgical excision for cancers of all stages comprised the study group.

Results :A total of 477 patients were included. There were 304(63.7%) patients of rectal cancer and 173(36.3%) patients of colon cancer. The distributions of clinical-pathological stage is stage I (5%),II(42.7%),III(36.4%) IV(15.9%).There were 19 patients (4%) complicated with anastomotic leakage,most occurred on LAR patients and operative mortality was 4 patients(0.8%).Stages I,II and III had five-year survivals of 100%,81.4% and 63.6% respectively, after curative resection.Stage IV had no five-year survival.

Conclusion : our series shows that rectal cancer with a lower anastomosia had a higher leakage rate than colon cancer.
