Abstract:
Objective:To investigate the ultrasonic characteristics of lymph node metastasis of papillary thyroid carcinoma and the predictive value of silent mating-type information regulation2 homolog1 (SIRT1) .Methods:90 PTC patients admitted from May. 2022 to May. 2023 were selected. According to the ultrasonography of patients with lymph node enlargement, hypoecho, unclear boundary, microcalcification and other conditions, the patients were divided into 26 cases in the LNM group and 64 cases without LNM. All patients underwent thyroid ultrasonography, and their serum samples were collected. Serum SIRT1 levels were detected by enzyme-linked immunosorbent assay (ELISA) double-antibody sandwich method. ROC was used to analyze the predictive value of ultrasonic characteristics and serum SIRT1 for LNM in PTC patients.Results:Compared with the group without lymph node metastasis, the proportion of patients with multiple tumor lesions ( P=0.001), tumor diameter ≥1 cm, hypoecho, unclear boundary and microcalcification was higher in the group with lymph node metastasis ( P<0.05). The serum SIRT1 level of LNM group (5.12±1.24) ng/mL was lower than that of (8.76±1.35) ng/mL in the other group ( P<0.05). ROC results showed that when the optimal cut-off value of serum SIRT1 was 7.59 ng/mL, the area under the curve was 0.78 (95% CI: 0.746- 0.835). The sensitivity and specificity were 79.43% and 71.56%, respectively. Multiple tumors, tumor diameter ≥1 cm ( P=0.018), unclear boundaries ( P=0.005), microcalcification ( P=0.001), and serum SIRT1 < 7.59 ng/mL ( P<0.001) had good clinical value in the evaluation of lymph node metastasis of papillary thyroid carcinoma, and the combined detection had a higher predictive value, with a sensitivity of 84.57%. Multivariate analysis showed that tumor boundaries were unclear ( OR=2.812, 95% CI: 1.220-6.482), microcalcification ( OR=4.145, 95% CI: 1.335-12.870), and serum SIRT1 decreased ( OR=2.399, 95% CI: 1.580-3.642) were independent risk factors for lymph node metastasis of papillary thyroid carcinoma ( P<0.05) . Conclusions:Lymph node metastasis of papillary thyroid carcinoma is characterized by unclear boundary and micro-calcification on ultrasound, and serum SIRT1 is decreased. The combined detection of ultrasound features and serum SIRT1 has a good predictive value in predicting lymph node metastasis in patients with papillary thyroid cancer.
