Predictors of retreatment after radiofrequency ablation of benign thyroid nodules: role of pre-treatment growth rate and viable volume

Pre-treatment growth rate and six-month viable volume are strong, independent predictors of retreatment after RFA of benign thyroid nodules. Incorporating these parameters into clinical decision-making may enhance patient selection, tailor treatment intensity, and inform follow-up intervals, thereby reducing the risk of retreatment and improving cost-effectiveness.
