Purpose: This study was conducted to identify prognostic factors in gastric cancer without lymph node metastasis and to specifiy which prognostic factors can be available in detail according to the depth of invasion.
Materials and Methods: This retrospective study was based on the medial records of 268 gastric cancer patients who received resectional therapy from 1990 to 1999. The patients who revealed pT2NOMO, pT3NOMO, pT4NOMO on postoperative pathologic reports were enrolled. The survival rate was analyzed according to clinicopathologic and therapeutic factors.
Results: According to the depth of invasion, the number of patients with pT2a, pT2b, pT3 and pT4 were 86 (32.1%), 56 (20.9%), 108 (40.3%), and 18 (6.7%) respectively. Age, depth of invasion, histological type, Borrmann type, and Lauren classification were statistically significant in the univariate analysis, and the age, the depth of invasion, and Lauren classification were independent prognostic factors identified by multivariate analysis. On multivariate analysis of subgroups according to the depth of invasion, the independent prognostic factors were age, Borrmann type, and Lauren classification in pT2, and age, Lauren classification , and vascular invasion in pT3. The prognostic factors of pT4 patients could not be analyzed due to limited sample size.
Conclusion: In advanced gastric cancer patients without lymph node metastasis, age, the depth of invasion, and Lauren classification should be checked to predict prognosis. In patients with pT2 lesion among the above patients, the Borrmann type should be added in check-list. (J Korean Gastric Cancer Assoc 2007;7:124-131)
