Abstract:

Objective This study retrospectively analyzed the clinical data of patients with papillary thyroid carcinoma (PTC) to explore the risk factors for central lymph node metastasis (CLNM) in the neck of PTC. Method The clinical data of 161 hospitalized patients who underwent thyroid surgery for the first time and were pathologically confirmed as PTC in Yingcheng People's Hospital from July 2020 to July 2021 were collected. The patients were divided into metastasis group and non metastasis group according to whether they had CLNM. Compare general information such as gender, age, and preoperative ultrasound imaging data between two groups to analyze the risk factors for CLNM in PTC patients. Result Univariate analysis showed that CLNM was associated with age, gender, ultrasound examination of tumor diameter, microcalcification, and presence of blood flow signals (P＜ 0.05), but not with factors such as tumor palpation results and tumor number (P ＞ 0.05). Multivariate analysis showed that age<45 years old, male, tumor diameter ＞ 1.0cm, ultrasound display of tumor microcalcification, and detection of blood flow signals within the tumor are risk factors for CLNM in PTC patients. Conclusion Men, age ＜ 45 years old, tumor size ＞ 1cm, microcalcifications, and internal blood flow signals within the lesion have a higher risk of developing CLNM. It is recommended that such PTC patients undergo preventive central lymph node dissection.
