title: Factors predicting survival in surgical palliative resection of stage IV colorectal cancer.
abstract: OBJECTIVE
  Colorectal cancer (CRC) harbors accumulated genetic alterations with cancer progression, which results in uncontrollable disease. To regulate the most malignant CRC, we have to know the most dismal phenotype of stage IV disease.
  
  
  METHODS
  A retrospective review of our Oncological Surgical Unit was performed (from 2005 to 2008) to extract the 52 resected stage IV CRC. Clinical variables were tested for their relationship to survival in a univariate prognostic analysis and revealed the interaction of the prognostic factors.
  
  
  RESULTS
  In stage IV CRC with noncurable resection, the most robust univariate predictors for poor prognosis were preoperative high value of CEA. In our series we did not observe correlation between poor prognosis and depth of invasion, age, gender, pathologic lymph node metastasis status, Ca 19.9 and postoperative therapy. The mean average survival rate was 10.9 months.
  
  
  CONCLUSIONS
  Our results suggested that only preoperative value CEA is associated with poor prognosis in stage IV CRC.
