目的 探讨不同标准对胰腺癌血管侵犯的判断作用.方法 回顾性分析经手术证实的56例胰腺癌MSCT图像,对胰腺周围5支大血管分别按照Loyer等、Lu等及长海医院标准评价各支血管的侵犯程度及肿瘤可切除性.以手术结果 为金标准,统计各标准评价的准确性,并计算其与手术间的Kappa系数.结果 Loyer等分型标准判断肿瘤可切除性的正确率、敏感性、特异性、阳性预测值、阴性预测值分别为86.79%、86.27%、86.90%、59.46%和96.60%,Kappa系数为0.623;Lu等分级法判断肿瘤可切除性的正确率、敏感性、特异性、阳性预测值、阴性预测值分别为93.21%、84.31%、95.20%、79.63%和96.46%,Kappa系数为0.777;长海医院标准判断肿瘤可切除性的正确率、敏感性、特异性、阳性预测值、阴性预测值分别为95.36%、84.31%、97.82%、89.58%和96.55%,Kappa系数为0.841.结论 长海医院标准对胰腺癌血管侵犯的评价是切实可行的.

Objective To investigate the ability of different standards on the evaluation of vascular invasion of pancreatic carcinoma. Methods The MSCT imagings of 56 cases of pancreatic carcinoma confirmed by surgery were analyzed retrospectively. The vascular invasion degrees of 5 large vessels around the pancreas were evaluated according to Loyer classification standard, Lu classification standard and the Changhai standard, the surgical result was used as the gold standard. The accuracy of different standards was evaluated, and the Kappa coefficient were calculated. Results The accuracy, sensitivity, specificity, positive predictive value and negative predictive value of Loyer classification standard were 86.79%, 86.27%, 86.90%, 59.46% and 96.60%, respectively, and the Kappa coefficient was 0.623. The accuracy, sensitivity, specificity, positive predictive value and negative predictive value of Lu classification standard were 93.21%, 84.31%, 95.20%, 79.63% and 96.46%, respectively, and the Kappa coefficient was 0.777. The accuracy, sensitivity, specificity, positive predictive value and negative predictive value of Changhai standard were 95.36%, 84.31%, 97.82%, 89.58% and 96.55%, respectively. The Kappa coefficient was 0.841. Conclusions The Changhai standard was feasible to evaluate the vascular invasion of pancreatic carcinoma.
