摘　　要：目的探讨肝泡状棘球蚴病(HAE)CT钙化类型预测其淋巴结转移的价值0x0E0xFF?厱0x180x0F方法回顾性收集经手术病理确诊的100例HAE患者,以50例存在淋巴结转移者为转移组、50例合并淋巴结反应性增生者为无转移组。对比组间患者一般资料及病灶术前CT表现(包括病灶数目、部位、最大径及钙化类型),对组间差异有统计学意义的临床及CT特征进行多因素logistic回归分析,筛选HAE淋巴结转移的独立预测因素;绘制受试者工作(ROC)曲线,计算曲线下面积(AUC),评价单一钙化类型及其联合其他独立预测因素预测HAE淋巴结转移的效能。结果转移组共62组淋巴结转移,包括39例单组、10例2组及1例3组淋巴结转移。组间肝内病灶部位、最大径及钙化类型差异均有统计学意义(P均<0.05),且均为HAE淋巴结转移的独立预测因素(P均<0.05)。单一CT钙化类型及其联合其他独立预测因素预测HAE淋巴结转移的AUC分别为0.757及0.859,差异有统计学意义(P=0.002)。结论HAE CT钙化类型可有效预测其淋巴结转移;联合病灶部位及最大径可提高预测效能。Objective To investigate the value of CT calcification type of hepatic alveolar echinococcosis(HAE)for predicting its lymph node metastasis.Methods Totally 100 patients with HAE confirmed by surgical pathology were retrospectively collected,among them 50 with lymph node metastases were divided into metastasis group,while the other 50 with lymph node reactive hyperplasia into non-metastasis group.Patients'general data,as well as preoperative CT findings,including the number,location,the maximum diameter and calcification type of lesions were compared between groups.Multivariate logistic regression analysis was performed for clinical and CT features being significant different between groups to screen the independent predictors of HAE lymph node metastasis.Receiver operating characteristic(ROC)curve was drawn,and the area under the curve(AUC)was calculated to evaluate the predictive efficacy of CT calcification type alone and combining with other independent predictors for predicting node metastasis of HAE.Results A total of 62 groups of lymph node metastases were detected in 50 patients in metastasis group,including 39 cases with single group lymph node metastasis,10 cases with 2 groups lymph node metastasis and 1 case with 3 groups lymph node metastasis.There were significant differences of location,the maximum diameter and CT calcification type of HAE lesions within liver between groups(all P<0.05),which were all independent predictors of HAE lymph node metastasis(all P<0.05).The AUC of CT calcification type alone and combining with other independent predictors for predicting node metastasis of HAE was 0.757 and 0.859,respectively,which were significant different(P=0.002).Conclusion CT calcification type of HAE could effectively predict lymph node metastasis,and the predictive efficacy might be improved by combining location and maximum diameter of HAE lesions.
