Clinical characteristics and risk factors of central lymph node and thyroid metastasis in patients with hypopharyngeal carcinoma

Our study sought to analyze the clinical characteristics and risk factors of central lymph node and thyroid metastasis in patients with hypopharyngeal carcinoma. The current study included a total of 152 patients who suffered from hypopharyngeal cancer in our hospital from January 2019 to December 2020. Univariate/multivariate Logistic regression analyses were applied to analyze the risk factors of both central lymph nodes and thyroid metastasis in patients with hypopharyngeal cancer. Significant differences were found in tobacco use, drinking history, PS score, site of tumor, pT and pN stage, pathological stage, differentiation degree, postoperative calcium ion level and postoperative FT3 level between the thyroid metastasis group and the non-thyroid metastasis group, and between the central lymph node metastasis group and the non-central lymph node metastasis group (P
