 In this study, we investigated the state of the detection of multiple metachronous lesions in 87 patients with early-stage colorectal cancer who had undergone colonoscopic treatment at our institution and were followed-up for at least one year. The cumulative detection rate of metachronous multiple lesions five years after colonoscopic treatment was 56.7%. Examination of clinicopathological characteristics of multiple metachronous lesions indicated that they tended to develop as a single lesion and occur in the right large intestine, and most were smaller than 10mm. The clinical course of multiple metachronous lesions was favorable both in patients who were treated and those who only underwent follow-up observations. The results of multivariate analysis of risk factors of multiple metachronous lesions revealed that an independent risk factor was the presence of three or more synchronous polyps. There is no established appropriate surveillance method for early-stage colorectal cancer after colonoscopic treatment; therefore, more research regarding this topic is needed in the future.
