Objective: A retrospective study was conducted on the factors influencing cervical lymph node metastasis and central lymph node metastasis of papillary thyroid microcarcinoma. Methods: Clinical data of 94 patients with papillary thyroid microcarcinoma admitted to the Affiliated BenQ Hospital of Nanjing Medical University from January 2019 to May 2021 were collected.The correlations between gender, age, tumor number, tumor location, multifocal, capsule invasion, blood flow signal, tumor side, tumor calcification, tumor aspect ratio, thyrotropin hormone, lymphocytic thyroiditis, degree of education, course of the disease, cervical lymph node metastasis and central lymph node metastasis were analyzed. Results: The rate of cervical lymph node metastasis was 47%(44/94). According to univariate analysis, sex, age and capsular invasion were risk factors for cervical lymph node metastasis of papillary thyroid microcarcinoma(P<0.05). Logistic regression analysis showed that male and capsular invasion were risk factors for cervical lymph node metastasis of papillary thyroid microcarcinoma(P<0.05).The rate of cervical central lymph node metastasis was 33%(31/94).Univariate analysis showed that gender and capsular invasion were risk factors for cervical central lymph node metastasis of papillary thyroid microcarcinoma(P<0.05).Logistic regression analysis showed that male and capsular invasion were risk factors for cervical central lymph node metastasis of papillary thyroid microcarcinoma(P<0.05).Conclusion: Prophylactic lymph node dissection is recommended for male patients with papillary thyroid microcarcinoma with capsule invasion to reduce the risk of reoperation due to tumor recurrence. |
