To develop and validate a high-accuracy tool for preoperatively assessing the risk of central lymph node metastasis (CLNM) in patients with papillary thyroid microcarcinoma (PTMC), thereby improving clinical decision-making.
Key Findings:
Five independent predictors of CLNM identified: age <46.5 years, male sex, capsular contact ≥50%, peritumoral hyperechogenicity, and heterogeneous echotexture.
The combined clinical-radiomics nomogram achieved an AUC of 0.900 in the validation set, outperforming the clinical model alone (AUC: 0.857 in training set).
Interpretation:
The clinical-radiomics nomogram provides a superior non-invasive pre-operative risk assessment tool for CLNM in PTMC patients, optimizing treatment strategies and improving patient management.
Limitations:
Retrospective design may introduce selection bias and confounding factors.
Single-center study limits generalizability of findings.
Conclusion:
The proposed nomogram enhances preoperative risk assessment for CLNM in PTMC, aiding in the decision-making process for treatment strategies and improving patient outcomes.
When Alexander Shifrin, MD, reflects on his 20 years as an endocrine surgeon, what stands out most is not the technical complexity of the operations he performs, but the consistency with which he can offer something rare when it comes to cancer care.
