Abstract:
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.
