title: [Prognostic analysis of different treatments for synchronous colorectal liver metastasis].
abstract: OBJECTIVE
  To evaluate the effects of different treatments on the prognosis of patients with synchronous colorectal liver metastasis(CLM).
  
  
  METHODS
  Clinicopathological data of 121 patients with synchronous CLM in The First Affiliated Hospital of Xinjiang Medical University between January 2010 and December 2014 were retrospectively analyzed. According to the metastatic lesions, patients were divided into simple operation group(22 patients, receiving operation only), simple chemotherapy group(43 patients, receiving chemotherapy only), and combination group(56 patients, receiving chemotherapy based on operation). The prognosis of patients in three groups was investigated. Univariate and multivariate analyses were performed through the long-rank test and Cox model to evaluate the related factors affecting prognosis.
  
  
  RESULTS
  The median survival time was 10(3-39) months in simple operation group, 7(3-36) months in simple chemotherapy group, and 18 (4-66) months in combination group. The differences among groups were all statistically significant (all P<0.05). Extent of lymph node metastasis, number of liver metastatic lesion, size of liver metastatic lesion, resection edge extent of liver metastatic lesion, and treatment method were independent factors of synchronous CLM(all P<0.05).
  
  
  CONCLUSIONS
  Combination therapy of a variety of treatment can prolong the survival of patients with synchronous CLM.
