Identifying Failure Predictors in Thyroid Nodule Radiofrequency Ablation Using Multivariate Analysis: A Single‐Centre Experience

Our results suggest that pre-treatment thyroglobulin levels may serve as a potential biochemical predictor of RFA success in benign thyroid nodules, while antibody positivity may suggest susceptibility to post-ablation hypothyroidism. While most existing literature focuses on imaging features (e.g., sonographic features) or surgeon technique, our findings highlight the unique importance of biochemical characteristics. Incorporating biochemical profiling into pre-procedural assessment could refine patient selection and enhance individualised treatment planning. Future prospective studies are warranted to validate Tg as a biomarker of RFA response.
