Objective To explore the clinicopathological characters of T_2 gastric cancer and the value of MSCT in the preoperative TNM staging of T_2 gastric cancer.Methods A total of 93 patients with T_2 gastric cancer were included in our study and underwent preoperative MSCT staging,who were confirmed by pathologic results.Then the results were compared with those of pathologic TNM staging.Also the clinicopathological features of the T_2 gastric cancer were analyzed.Results There were no statistically significant differences in the clinicopathological characters among T_2 aand T_2b patients(P0.05).Comparing with pathologic TNM stage,the T staging accuracy of MSCT was 91.40%(85/93),the N staging accuracies of CT was 66.67%(62/93),in which,68.18%(30/44),65.00%(26/40),60.00%(3/5)and 75.00%(3/4)were for pN0,pN1,pN2 and pN3.And the TNM staging accuracies of CT was 67.74%(63/93),in which,68.18%(30/44),64.10%(25/39),60.00%(3/5)and 100%(5/5)were for stageⅠ,Ⅱ,Ⅲ and Ⅳ.Conclusion There are no significant different on clinicopathology features among T_2 aand T_2bpatients.MSCT can clearly determine the preoperative TNM staging of T_2 gastric cancer.
