CT增强对甲状腺乳头状癌颈部淋巴结转移的诊断价值
Value of contrast-enhanced CT in diagnosis of cervical lymph node metastasis in papillary thyroid carcinoma
摘要
Abstract
Objective To explore the diagnostic value of contrast-enhanced CT in papillary thyroid carcinoma(PTC)with cervical lymph node metastasis(CLNM).Methods A total of 270 PTC patients admitted to Haining People's Hospital from September 2019 to September 2022 were retrospectively collected.According to the clinical,imaging and pathological data,the influencing factors of CLNM in PTC were analyzed.A multivariate logistic regression model for predicting PTC with CLNM was established.The receiver operating characteristic(ROC)curve was used to evaluate the performance of the model.Results Univariate analysis showed that CLNM status was significantly different in patients with different age,sex,length of transverse axis,and contrast-enhanced CT signs including capsule interruption sign,longitudinal location of capsule invasion,capsule curve contact length(CCL),and vascular crossing sign(all P<0.05).Multivariate analysis showed that age,gender,capsule interruption sign,capsule invasion into the lower pole of the thyroid,and vascular crossing sign were asso-ciated with CLNM(all P<0.05).A binary logistic regression model for predicting CLNM in PTC was established based on these five factors.The area under the ROC curve of the model was 0.798(95%CI:0.745-0.852),the sensitivity was 0.776,and the specificity was 0.701,which was better than the length of transverse axis and capsule CCL.Conclusions Contrast-enhanced CT signs are of great value in the diagnosis of PTC with CLNM.关键词
