术前颈部增强CT联合颈部超声检查对头颈部鳞状细胞癌患者颈部淋巴结转移的诊断价值
Value of preoperative cervical enhanced CT and cervical ultrasound in diagnosing cervical lymph node metastases in patients with head and neck squamous cell carcinoma
摘要
Abstract
Objective To assess the diagnostic utility of preoperative cervical enhanced CT in conjunction with cervical ultrasound(US)for cervical lymph node metastases in patients with head and neck squamous cell carcinoma(HNSCC).Methods The clinical data of 98 HNSCC patients admitted to Zhengzhou Central Hospital from July 2021 to July 2024 were retrospectively collected.Based on the findings of the pathological investigation,the patients were divided into the metastatic group(n=54)and the non-metastatic group(n=44).The basic features of enhanced CT and US examination of the neck were compared between the two groups,and the positive predictive value,nega-tive predictive value,sensitivity,specificity,and accuracy of cervical enhanced CT,US,and combined examinations for diagnosing cervical lymph node metastases in HNSCC patients were calculated.Results Among 54 patients with cervical lymph node metastases,158 positive lymph nodes were detected.The detection rates of US,enhanced CT,and the combined examinations were 73.4％,79.1％,and 94.9％,re-spectively.In terms of US features,the proportions of cases with calcification,strong echoes,indistinct lymph node margins,aspect ratios＞2,and peripheral blood flow in the metastatic group were all higher than those in the non-metastatic group(all P＜0.05).The analysis of CT features showed that the proportions of patients with round or irregular appearance,heterogeneous enhancement or calcification,cystic or necrotic changes,and internal enhancement in the metastatic group were all higher than those in the non-metastatic group(all P＜0.05).The positive predictive value,negative predictive value,sensitivity,accuracy,and specificity of the combined examinations for diagnosing cervical lymph node metastases in HNSCC patients were 0.781,0.882,92.59％,81.63％,and 68.18％,respectively,and the area under the receiver operating characteristic curve was 0.886.Conclusions Cervical US combined with enhanced CT has good diagnostic value in the evaluation of cervical lymph node metastases in HNSCC patients,and can be used as one of the diagnostic methods of cervical lymph node metastases.关键词
