Analysis of value of ultrasound features in predicting cervical lymphatic metastasis of thyroid micropapillary carcinoma
Objective To investigate the correlation and predictive value of ultrasound results in patients with papillary thyroid microcarcinoma(PTMC)with cervical lymph node metastasis.Methods Retrospective study,78 PTMC patients admitted to our hospital from December 2021 to December 2023 were selected as the study subjects.Based on pathological results,they were divided into metastatic group of 38 cases and non metastatic group of 40 cases.Perform multiple logistic regression analysis on the baseline data features and ultrasound image features of patients.Results ①The patients in the metastatic group were male,＜45 years old,the number of multiple cases and focal diameter＞5mm were higher than those in the non-metastatic group,and the differences were statistically significant(P＜0.05).②The aspect ratio＜1 and the ratio of contact membrane in the metastatic group were 39.47％and 68.42％,respectively,higher than those in the non-metastatic group(P＜0.05).The other ultrasonic characteristics were compared with those in the non-metastatic group(P＞0.05);③ Gender,age,single or multiple cases,and contact with the capsule were risk factors for cervical lymph node metastasis in PTMC patients(P＜0.05).Conclusion The ultrasound characteristics of PTMC patients in terms of gender,age,single/multiple lesions,and their relationship with the capsule are correlated with the occurrence of cervical lymph node metastasis,which is an important reference for preoperative clinical diagnosis.
