title: [Characteristics of metastasis and recurrence following curative resection for colonic carcinoma].
abstract: OBJECTIVE
  To investigate the characteristics of metastasis and recurrence following curative resection for colonic carcinoma,and analyze the prognosis.
  
  
  METHODS
  The clinicopathological and follow-up data of 310 patients with colon carcinoma undergoing curative resection were analyzed retrospectively.
  
  
  RESULTS
  The recurrence rate after curative resection was 23.2% (72/310). The 5-year survival rate was 64.6%. Hepatic metastasis accounted for 38.9% of the cases. Gross classification,histological type, differentiation, lymph node metastasis were correlated with metastasis/recurrence. Univariate analysis revealed that gross classification, histological type, differentiation, lymph node metastasis, blood vessel invasion, TNM Stage, postoperative chemotherapy, portal chemotherapy were prognostic factors. Cox regression analysis revealed that only gross classification, lymph node metastasis, postoperative chemotherapy, portal chemotherapy were independent prognostic factors.
  
  
  CONCLUSIONS
  Liver is the most common metastatic site after curative resection for colonic carcinoma. Gross classification, lymph node metastasis, postoperative chemotherapy, and portal chemotherapy are independent prognostic factors.
