Risk factors of cervical lymph node metastasis in thyroid micropapillary carcinoma / 中华普通外科杂志

ABSTRACT

Objective:To study the clinicopathological features of thyroid micropapillary carcinoma and the risk factors of cervical lymph node metastasis.Methods:Two hundred and ninty-eight thyroid micropapillary carcinoma patients diagnosed by postoperative pathology at the Affiliated Hospital of Xuzhou Medical University from Sep 2018 to Jun 2021 were retrospectively divided into metastasis group and non metastasis group according to whether there were cervical lymph node metastasis. Multivariate logistic regression was used to analyze the independent risk factors of cervical lymph node metastasis in thyroid micropapillary carcinoma.Results:The cervical lymph node metastasis rate was 41.3%. Univariate analysis showed that there were significant differences between the two groups in patient's height, maximum tumor diameter, calcification, capsule infiltration and Hashimoto thyroiditis (all P<0.05). Multivariate logistic regression analysis showed that height ≥ 160.5cm, maximum tumor diameter ≥5.5 mm, capsule infiltration and Hashimoto thyroiditis were independent risk factors for cervical lymph node metastasis. Conclusion:Cervical lymph node metastasis in patients with thyroid micropapillary carcinoma is related to the maximum diameter, height, capsule infiltration and Hashimoto thyroiditis.
