Analysis Of Consistency Between Clinical And Pathological TNM Staging For Gastric Cancer

Objective To explore the consistency between preoperative clinical TNM stage and postoperative pathology TNM stage of gastric cancer and look for the under reason.Methods64patients of gastric cancer with complete clinical data from December2010to December2011in Gansu provincial hospital were enrolled into this study. All cases were performed postoperative pathologic TNM stage according to the TNM stage criterion of gastric cancer from JGCA(the14th edition,2010), and the results were compared with preoperative TNM stage, then we studied the coincidence rate of both staging by analysis of the consistency of T staging, N staging and M staging using SPSS18.0.Results The Kappa value from T staging of preoperative and postoperative is0.729, it shows us a good consistency, but the coincidence of cT2group is the lowest(P<0.05).The N stage’s consistency is lower, Kappa value is only0.216, among them, the coincidence of cN3group is the lowest(P<0.05).For M staging, Kappa value is0.743,they have a good consistency.Conclusions According to the General Rules for Gastric Cancer Treatment, the author can make a accurate TNM stage and individual treatment plan for gastric cancer patients in clinic. But the overestimate and underestimate still existed, especially in N staging. Therefore, make a accurate judge for N staging according to all kinds of preoperative clinical data and images is the key for improvement of preoperative TNM staging accuracy and treatment.
