Methods: 103 patients who attended Urumqi Hospital of Traditional Chinese Medicine and were diagnosed as PTMC by pathology between December 2019 and December 2022 were collected, and the correlation between gender, age, ethnicity, body mass index, TSH value, tumor diameter, peritumoral invasion, microcalcified foci, the number of cancer foci, the presence of comorbidities and CLNM was analyzed. Results: The incidence of CLNM in PTMC was 39.87% (41/103), and by univariate analysis, gender, age, tumor diameter, microcalcified foci, and the number of cancer foci were the risk factors for the occurrence of CLNM in PTMC (P P < 0.05). Conclusion: Gender, age, ethnicity, body mass index, TSH value, tumor diameter, peritumoral invasion, microcalcified foci, number of cancer foci, and comorbidities can be used as predictive factors for quantitative risk assessment of the occurrence of CLNM in PTMC, which can provide a reference for further selection of suitable treatment options.展开更多
