Our study aims to identify the clinical factors associated with CLNM and develop a nomogram for making individualized clinical decisions.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>The perioperative data of 1,054 consecutive patients between Jan 2019 and April 2021, in our center, were reviewed and analyzed. A total of 747 patients with histopathologically confirmed classical PTC were included as the training cohort and 374 (50% training cases) patients were randomly selected to build a validating cohort <jats:italic>via<\/jats:italic> internal bootstrap analysis. Univariate and multivariate logistic regression were used to analyze the correlation between clinicopathological characteristics and CLNM.<\/jats:p><\/jats:sec><jats:sec><jats:title>Result<\/jats:title><jats:p>In the training cohort, 33.6% (251\/747) of patients with classical PTC were confirmed with CLNM. And the CLNM was determined in 31.4% (168\/535) of non-Hashimoto\u2019s thyroiditis (HT) patients versus 39.2% (83\/212) in HT patients (p=0.043). Four factors including gender, age, size, and HT status were confirmed significantly associated with CLNM. The established nomogram showed good discrimination and consistency with a C-index of 0.703, supported by the internal validation cohort with a C-index of 0.701. The decision curve analysis showed the nomogram has promising clinical feasibility.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Our study suggested that classical PTC patients with features like male gender, age&amp;lt;55 years old, tumor size&amp;gt;1cm, and HT condition had a higher risk of CLNM. And the nomogram we developed can help surgeons make individualized clinical decisions in classical PTC patients during preoperative and intraoperative management.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fendo.2022.868606","type":"journal-article","created":{"date-parts":[[2022,5,20]],"date-time":"2022-05-20T12:40:13Z","timestamp":1653050413000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":16,"title":["Hashimoto\u2019s
