Abstract

Objective: Papillary thyroid microcarcinoma (PTMC) is a variant of papillary thyroid carcinoma that measures less than 10mm on the largest diameter. There are some worse prognostic factors related to lymph node metastases. The aim of this study is to analyze the factors associated with PTMC with metastatic lymph nodes. Methods: We included 127 patients who diagnosed papillary microcarcinoma and undergone partial or total thyroidectomy at Ha Noi Medical University Hospital (from October 2020 to August 2022). Chi-Square and Fisher’s Exact Test were used to analyzed. The statistical significance was set at p < 0.05. Results: There were association between lymph node metastasis and multifocal cancer, bilateral cancer, capsular invasion (p<0.05). Lymph node metastasis was associated with both small PTMC (5/36 cases) and large PTMC (31/36 cases). Conclusions: For PTMC, multifocal, bilateral cancer and capsular invasion are associated with the high risk of lymph node metastasis.
