title: [A retrospective survival analysis of with pulmonary metastasis from colorectal cancer].
abstract: OBJECTIVE
  To evaluate the survival rate after pulmonary resection for metastatic colorectal cancer(CRC).
  
  
  METHODS
  Clinical data of 77 patients with pulmonary metastasis from CRC between January 2005 and October 2008 in the Zhongshan Hospital, Fudan University were retrospectively analyzed.
  
  
  RESULTS
  There were 38 patients with synchronous pulmonary metastasis, of whom 2 underwent resection for pulmonary metastasis. The median survival time of two groups was 25 months and 18 months, which was not significantly different (P=0.33). There were 39 cases of metachronous pulmonary metastasis, of whom 28 received pulmonary metastasis resection. The 1-year and 3-year survival rates of 2 groups were 93.3% and 58.5%, and 38.8% and 19.1%, respectively. The median survival time of two groups was 26.7 months and 8 months, and the difference was statistically significant (P=0.004).
  
  
  CONCLUSIONS
  Surgical resection can improve the survival rate in patients with pulmonary metastasis from colorectal cancer.
