title: Prognostic factors of advanced gastric carcinoma without serosal invasion (pT2 gastric carcinoma).
abstract: OBJECTIVE
  The purpose of this study was to investigate the prognostic factors of advanced gastric carcinoma without serosal invasion (pT2 gastric carcinoma), for the planning of therapeutic strategy.
  
  
  METHODS
  Prognostic factors were evaluated by univariate and multivariate analysis in a total of 304 curatively resected pT2 gastric carcinoma patients in whom the tumor invaded the muscularis propria or the subserosa.
  
  
  RESULTS
  Macroscopic type, depth of invasion, lymph node metastasis and venous invasion were significantly related to outcome, using univariate analysis. Lesions resembling early gastric carcinoma had better prognosis than lesions belonging to one of the Borrmann types. Multivariate analysis (Cox's proportional hazards model) demonstrated that macroscopic type, lymph node metastasis and venous invasion, but not depth of invasion, were significant prognostic factors.
  
  
  CONCLUSIONS
  Macroscopic appearance, lymph node metastasis and venous invasion were the important prognostic factors of pT2 gastric carcinoma. Extensive lymph node dissection and aggressive post-operative chemotherapy should be performed, especially in Borrmann type lesions with lymph node metastasis.
