ABSTRACT

Objective:To investigate the application of ultrasound thyroid imaging report and data system (TI-RADS) score, serum galectin-3, microRNA (miR) -599 in cervical lymph node metastasis of papillary thyroid carcinoma (PTC).Methods:A total of 98 patients with PTC admitted to China Resources Medical Huaibei Miners General Hospital from March 2019 to March 2021 were selected and divided into the metastasis group (48 cases) and the non-metastasis group (50 cases) according to the state of cervical lymph node metastasis dignosedby the pathological examination. The baseline data, ultrasound TI-RADS score, serum galectin-3, miR-599 were compared between the two groups. Multivariate Logistic regression analysis was used to analyze the related factors of cervical lymph node metastasis, receiver operating characteristic (ROC) curve and the area under curve (AUC) were used to analyze the value ofpredicting cervical lymph node metastasis.Results:The ultrasound TI-RADS scores and galectin-3 level in the metastasis group were higher than those in the non-metastasis group: (11.72 ± 2.85) scores vs. (8.15 ± 2.60) scores, (5.54 ± 1.76) μg/L vs. (4.02 ± 1.27) μg/L, the miR-599 level in the metastasis group was lower than that in the non-metastasis group: 0.25 ± 0.08 vs. 0.36 ± 0.10, there were statistical differences ( P<0.05). The results of multivariate Logistic regression analysis showed that the ultrasound TI-RADS score, serum galectin-3 and miR-599 were still associated with cervical lymph node metastasis in PTC patients after controlling the clinical stage ( P<0.05). The results of ROC curve analysis showed that the AUC for ultrasound TI-RADS score, serum galectin-3 combined with miR-599 in evaluating cervical lymph node metastasis was the largest (0.889). The metastasis rate of patients with high levels of ultrasound TI-RADS and serum galectin-3 were higher than those with low levels, and the metastasis rate of patients with high level of miR-599 was lower than that of patients with low level , there were statistical differences ( P<0.05). Conclusions:Ultrasound TI-RADS score, serumgalectin-3, miR-599 are related to cervical lymph node metastasis in PTC patients, and combined detection is expected to become a scheme for evaluating cervical lymph node metastasis.
