摘要
目的:探讨64层MSCT对进展期胃癌术前T分期的准确性。方法:搜集经术前胃镜及病理活检证实的100例胃癌患者的病例资料,对其进行常规平扫及三期动态增强扫描后进行术前T分期,并与术后病理T分期对照,分期的准确性采用Kappa一致性检验。结果:MSCT对T2、T3、T4期胃癌分期的敏感度为58.33%、88.24%、80.95%;特异度为97.22%、75.76%、93.65%;符合率为91.67%、82.14%、90.48%,T分期总的符合率为82.14%。结论:64层MSCT在进展期胃癌术前T分期中具有较高的准确性,对于胃癌术前评估及预后具有重要的指导意义。
Objective：To study the accuracy of 64-slice spiral CT （MSCT）in the diagnosis of T-staging of advanced gastric cancer before surgery.Methods：Clinical materials of 100 patients with gastroscopy and biopsy proved gastric cancer were recruited.MSCT were performed with plain and triphasic dynamic contrast enhancement before surgery.T-staging was evaluated and correlated with that of pathology.Kappa consistency test was used to study the accuracy.Results：The sensitivity of MSCT for T-staging of T2、T3 and T4 was 58.33%、88.24% and 80.95%,respectively.The specificity for T2、T3 and T4 was 97.22%、75.76% and 93.65% ,respectively.The accuracy for T2、T3 and T4 was 91.67%、82.14% and 90.48%,respectively.The accuracy on T-staging as a whole was 82.14%.Conclusion：Relatively high accuracy in T staging of advanced gastric cancer before surgery could be obtained by 64-slice MSCT,and it can provide reliable information for surgery guidance and prognosis prediction.
