Abstract

Objective: To evaluate the characteristics of lymph node metastasis in patients with papillary thyroid microcarcinoma (PTMC) at the National Hospital of Endocrinology. Subjects and Methods: A cross-sectional descriptive study was conducted on 181 patients diagnosed with lymph node metastatic PTMC who underwent surgery at the National Hospital of Endocrinology from January to April 2025.Results: The study revealed that the majority of PTMC patients were female (72.9%), under the age of 55 (87.3%), with incidental detection during routine health check-ups (58.6%), and a high prevalence of overweight/obesity (47.5%). Lymph node metastases were predominantly located in the central cervical compartment (78.5%), with a mean number of 3.0 ± 2.6 nodes and an average metastatic node size of 6.1 ± 3.8 mm. In terms of staging, most patients were classified as T1a (89.0%), with the majority having a low risk of recurrence (79%) and a very low risk of disease-specific mortality (87.3%).Conclusion: These findings highlight the importance of early screening and comprehensive clinical assessment in improving the diagnostic accuracy and prognostic stratification of papillary thyroid microcarcinoma with lymph node metastasis.
