The aim of this study was to investigate the factors that affect cervical lymph node metastasis (CLNM) in individuals with medullary thyroid carcinoma (MTC) in terms of ultrasonic characteristics and other parameters. Single-factor χ analysis showed that the ultrasonic characteristics of tumor size >10 mm, unclear boundary, irregular pattern and capsular invasion, as well as pre-operative calcitonin level >302.50 pg/mL (p < 0.001) and age ≤52.50 y (p = 0.036), were risk factors for CLNM in individuals with MTC. Multivariate logistic regression analysis showed that age ≤52.50 y (odds ratio = 3.796; 95% confidence interval, 1.010-14.259; p = 0.048), irregular pattern (odds ratio = 5.262; 95% confidence interval, 1.200-23.084; p = 0.028) and tumor size >10 mm (odds ratio = 7.789; 95% confidence interval, 1.123-54.005; p = 0.038) were independent risk factors for CLNM in individuals with MTC. Individuals with MTC aged ≤52.50 y with an irregular pattern and tumor size >10 mm were more likely to develop CLNM. In addition, those with a pre-operative calcitonin level >302.50 pg/mL were more likely to have CLNM.

The scope of neck lymph node dissection remains controversial for unilateral papillary thyroid carcinoma (UPTC) patients with no clinical evidence of lymph node metastasis (cN0). This study aims to build and validate a model for predicting central lymph node metastasis (CLNM) in UPTC patients through preoperative basic information and intraoperative rapid frozen pathology results. Retrospective analysis covered 1928 patients with PTC from the Wuhan Union Hospital database (2010-2020), randomly split into training and validation sets in a 7:3 ratio.

Objective: To analyze the clinicopathological features and predictors of lymph node metastasis (LNM) in the diffuse sclerosing variant of papillary thyroid carcinoma (DSV-PTC) and compare these findings with conventional papillary thyroid carcinoma (C-PTC) in pediatric populations.
Methods: Patients aged 18 years or younger who were preoperatively diagnosed with PTC and underwent thyroidectomy at the First Affiliated Hospitals of Nanchang University from January 2017 to May 2024 were included in this study. Demographic and clinicopathological characteristics were retrospectively analyzed.

Objective: The aim of this study was to establish an ensemble learning model based on clinicopathological parameter and ultrasound radomics for assessing the risk of lateral cervical lymph node with short diameter less than 8 mm (small lymph nodes were used instead) metastasis in patients with papillary thyroid cancer (PTC), thereby guiding the selection of surgical methods.
Methods: This retrospective analysis was conducted on 454 patients diagnosed with papillary thyroid carcinoma who underwent total thyroidectomy and lateral neck lymph node dissection or lymph node intraoperative frozen section biopsy at the First Hospital of China Medical University between January 2015 and April 2022. In a ratio of 8:2, 362(80%) patients were assigned to the training set and 92(20%) patients were assigned to the test set.
