title: [Prognostic factors in 138 patients with node-negative gastric cancer].
abstract: OBJECTIVE
  To investigate the risk factors for the prognosis in patients with node-negative gastric cancer.
  
  
  METHODS
  Clinicopathological characteristics of 138 patients with node-negative gastric carcinoma undergoing curative gastrectomy from January 2000 to December 2005 were retrospectively analyzed.
  
  
  RESULTS
  The overall 5-year survival rate was 62.4%. The univariate analysis revealed that tumor size, tumor location, cell differentiation, invasive depth, operative type and Lauren histologic type had significant effects on the survival. The independent prognostic factors of these patients were tumor size, cell differentiation, and serosal involvement in multivariate analyses.
  
  
  CONCLUSIONS
  For node-negative gastric cancer patients, tumor size, poor differentiation and serosal involvement are important markers to evaluate prognosis.
