目的：探讨多层螺旋 CT 测量胃癌体积在 N 分期预测方面的价值。方法收集经病理证实的胃癌患者(n=193)CT 资料,测量门脉期肿瘤体积,比较该结果和相应 N 分期的相关性并用 ROC 曲线分析其区分不同 N 分期的诊断效能。结果肿瘤体积测量结果具有较好的一致性(Kappa 值分别为0.77、0.72、0.69,P <0.05),且与相应的 N 分期呈正相关(r =0.568,P <0.05)。区分 N0和 N1~N3组、N0~N1和 N2~N3组、N0~N2和 N3组曲线下面积分别为0.79、0.80、0.82,体积阈值12.06 cm3、22.35 cm3、25.95 cm3,敏感度55%、66%、62%,特异度95%、86%、89%。结论CT 测量胃癌体积对 N 分期评估有一定应用价值,有利于指导临床选择个体化的治疗方案。

Objective To evaluate the value of volume measured by multi-slice spiral CT in preoperative N staging of gastric canc-er.Methods CT data of 1 93 cases of gastric cancer proven pathologically were collected and analyzed.Volume of the tumor was cal-culated in the portal phase,and the correlation between the results and N staging was evaluated.ROC curve was used to get diagnos-tic value to differentiate N stages.Results Intra-observer Kappa value was 0.77 (P < 0.05 ),0.72 (P < 0.05 ),Inter-observer Kappa value was 0.69 (P <0.05).The tumor volume data was positively correlated with different N stages (r=0.568,P <0.05). ROC curve showed that the volume could help differentiate between stage N0 and stage N1 - N3 (cutoff 12.06 cm3 ,sensitivity 55%,specificity 95%),stage N0-N1 and stage N2-N3 (cutoff 22.35 cm3 ,sensitivity 66%,specificity 86%),stage N0-N2 and stage N3 (cutoff 25.95 cm3 ,sensitivity 62%,specificity 89%)respectively.Conclusion The volume of gastric cancer measured by CT plays an important part in predicting lymph node metastasis staging and optimizing individualized clinical strategy for patients.
