title: Survival benefit in patients after palliative resection vs non-resection colon cancer surgery.
abstract: OBJECTIVE
  To evaluate survival in patients undergoing palliative resection versus non-resection surgery for primary colorectal cancer in a retrospective analysis.
  
  
  METHODS
  Demographics, TNM status, operating details and survival were reviewed for 67 patients undergoing surgery for incurable colorectal cancer. Palliative resection of the primary tumor was performed in 46 cases in contrast to 21 patients with non-resection of the primary tumor and bypass surgery. Risk factors for postoperative mortality and poor survival were analyzed with univariate and multivariate analyses.
  
  
  RESULTS
  The two groups were comparable in terms of age, gender, preoperative presence of ileus and tumor stage. Multivariate analysis showed that median survival was significantly higher in patients with palliative resection surgery (544 vs 233 d). Differentiation of the tumor and tumor size were additional independent factors that were associated with a significantly poorer survival rate.
  
  
  CONCLUSIONS
  Palliative resection surgery for primary colorectal cancer is associated with a higher median survival rate. Also, the presence of liver metastasis and tumor size are associated with poor survival. Therefore, resection of the primary tumor should be considered in patients with non-curable colon cancer.
