Purpose: Early colorectal cancer is defined as invasive tumor, limited to the mucosa or submucosa. The incidence of early colorectal cancer detection has been increased due to well designed screening technology and development of colonoscopy. The novel treatment of early colorectal cancer is still not settled despite of this advancement. We performed retrospective study about outcomes of colorectal cancer after radical resection or local resection. Methods: Sixty two patients, diagnosed as early colorectal cancers by pathology, were selected for this case study. The hospital records were reviewed retrospectively and the following was found: Twenty four patients received local resection such as colonoscopic polypectomy or local resection of colon. Remaining thirty-eight patients received radical resection. The clinicopathologic features of two groups were analyzed statically and survival rate was compared. Results: The clinical features were similar between two groups including sex, age, stage, tumor size and differentiation. The median follow-up duration was 47.3 months (range: 2∼152 months). Survival rate was not different according to resection type. Recurrent cases were one patient from each group. They were all submucosal tumors. Conclusions: The local resection is safe treatment modality for early colorectal cancer. However, case selection for local resection should be cautious because submucosal cases have more recurrent potential. Longterm follow-up will be needed to achieve safety of early colorectal cancer.
