ABSTRACT
PURPOSE:
T2 gastric cancer is tumor invading proper muscle or subserosal layer. The 2002 American Joint Committee on Cancer subdivided the pT2 gastric adenocarcinoma into a type pT2a (invasion of the proper muscle) and a type pT2b (invasion of the subserosa). The aim of this study was to evaluate the differences between pT2a and pT2b gastric cancers of the clinicopathological features and the prognostic factors.METHODS:
A series of curative operations were performed on 194 patients with pT2 gastric cancer from January 1999 to February 2006. We reviewed, retrospectively, the clinicopathologic characteristics, the 3-year disease free survival and the 5-year disease specific survival rates.RESULTS:
There were significant clinicopathologic differences between pT2a and pT2b gastric cancer in tumor size and the number of metastatic lymph nodes. Both of the 3-year disease free survival time and the 5-year disease specific survival time were much longer for the pT2a gastric carcinoma patients than those for the pT2b gastric carcinoma patients.CONCLUSION:
It is important to consider the differences between pT2a and pT2b gastric cancers for prediction of recurrence or prognosis. Furthermore, new staging of pT2a and pT2b cancer may be necessary.
