title: [Analysis of prognostic factors after curative resection for gallbladder carcinoma].
abstract: OBJECTIVE
  Despite the development in diagnostic tools, gallbladder carcinoma is often diagnosed at an advanced stage. Therefore, early diagnosis and radical resection are most important factors for the prognosis of gallbladder carcinoma. However, prognostic factors after radical resection of gallbladder carcinoma have not been well identified. The aim of this study was to evaluate the prognostic factors of gallbladder carcinoma after curative resection.
  
  
  METHODS
  We reviewed the records of the 115 patients with gallbladder carcinoma who underwent curative surgery between 1989 and 2004 at Yonsei University Medical Center (YUMC). The relationship between survival and clinicopathological variables was assessed.
  
  
  RESULTS
  In 311 patients presenting with gallbladder carcinoma, 195 patients (62.5%) were radically resected. Among 195 patients, 80 patients were excluded because of incomplete clinicopathologic data and unsatisfactory follow-up. The 5 year overall survival rate was 36.0%, and disease free 5 year survival rate was 3.9%. Univariate analysis showed that survival was closely related to gross morphology, depth of tumor invasion, lymph node metastasis and preoperative serum CA19-9 level. Three significant factors identified by multivariate analysis were depth of tumor invasion, gross morphology, and preoperative serum CA19-9 level.
  
  
  CONCLUSIONS
  Depth of tumor invasion, gross morphology, and preoperative serum CA19-9 level are independent significant prognostic factors of resectable gallbladder carcinoma.
