- Study identifies predictors of early complete resolution (within 1 year) after radiofrequency ablation (RFA) for low-risk papillary thyroid microcarcinoma (PTMC).
- Cumulative complete resolution rates were 62.2% at 1 year and 98.7% at 2 years.
- Independent predictors of complete resolution within 1 year include normal thyroglobulin antibody (TgAb) and thyroid peroxidase antibody (TPOAb) levels, nodule diameter ≤ 5 mm, and absence of intratumoral vascularity.
- Energy density showed an inverted U-shaped relationship with resolution probability within 1 year.
- Findings suggest RFA achieves favorable long-term efficacy for low-risk PTMC, with early resolution predictable by specific factors.
- The study provides insights for refining RFA techniques and developing personalized follow-up strategies.
