T2期胃癌临床病理特征及多层螺旋CT术前TNM分期价值

目的：探讨T2期胃癌临床病理特征及多层螺旋CT（MSCT）在T2期胃癌术前TNM分期中的价值。方法单因素分析93例T2期胃癌患者的临床病理特征，并行MSCT术前TNM分期，与术后病理检查结果进行对照。结果浅肌层癌（T2a）和深肌层癌（T2b）两组患者在临床病理特征上差异无统计学意义（P＞0．05）。MSCT对T2期胃癌T分期准确率为91．40％（85／93）；N分期准确率为66．67％（62／93），其中对pN0、pN1、pN2和pN3期判断的准确率分别为68．18％（30／44）、65．00％（26／40）、60．00％（3／5）和75．00％（3／4）；TNM分期的准确率为67．74％（63／93），其中Ⅰ、Ⅱ、Ⅲ和Ⅳ期分期准确率分别为68．18％（30／44）、64．10％（25／39）、60．00％（3／5）和100％（5／5）。结论T2a和T2b患者在临床病理特征上没有显著差异。MSCT动态增强扫描对T2期胃癌术前TNM分期具有重要的临床价值。

The clinicopathology features of the T2 gastric cancer and value of enhanced multiphasic spiral CT in TNM staging of T2 gastric cancer

Objective To explore the clinicopathological characters of T2 gastric cancer and the value of MSCT in the preop‐erative TNM staging of T2 gastric cancer .Methods A total of 93 patients with T2 gastric cancer were included in our study and un‐derwent preoperative MSCT staging ,who were confirmed by pathologic results .Then the results were compared with those of path‐ologic TNM staging .Also the clinicopathological features of the T2 gastric cancer were analyzed .Results There were no statistical‐ly significant differences in the clinicopathological characters among T2a and T2b patients (P>0 .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 ac‐curacies 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 T2a and T2b patients .MSCT can clearly determine the preoperative TNM staging of T2 gastric cancer .
