title: [Medium and long-term outcomes of laparoscopic right hemicolectomy for colon cancer].
abstract: OBJECTIVE
  To evaluate factors associated with postoperative survival after laparoscopic right hemicolectomy for colon cancer.
  
  
  METHODS
  Clinical data of patients undergoing laparoscopic right hemicolectomy in the Department of General Surgery, the Peking University Third Hospital from February 2004 to March 2011 were obtained and analyzed. Kaplan-Meier method was used to calculate survival rate and univariate analysis was performed. Proportional-hazards regression model(Cox model) was used for multivariate analysis.
  
  
  RESULTS
  A total of 164 cases were included in this study. The conversion rate was 7.3%(12/164) and the postoperative morbidity was 18.9%(31/164). After a median follow-up period of 27 months(range from 5 to 85 months), the 5-year overall survival rate was 81.5% and the 5-year disease free survival rate was 75.7% and 5-year cancer related survival rate was 78.7%. Both univariate and multivariate analysis showed that the TNM staging and conversion were independent prognostic factors(P<0.05).
  
  
  CONCLUSIONS
  The tumor stage and conversion are independent prognostic factors for patients undergoing the laparoscopic right hemicolectomy.
