摘要: Background The aim of this study was to evaluate the predictive role mismatch repair (MMR) system and p53 expression for lymph node metastasis long-term survival in patients with T1 T2 colorectal cancer. Methods A total 543 or cancers who underwent radical surgery regional lymphadenectomy from December 2007 2009 were analyzed. Predictive factors prognostic analyzed. Results During median follow-up period 4 years, 5-year disease-free rate without 94.8%, which significantly higher than that those metastases (85.2%; P < 0.001). On multivariate analysis, gender, tumor location, N category, lymphatic invasion, vascular perineural invasion independent survival; however MMR defect, expression, microsatellite instability (MSI) not. The presence budding predictors metastasis. Conclusions In cancer, metastasis; however, MSI not predictive. J. Surg. Oncol. 2014 109:848–852. © Wiley Periodicals, Inc.
