ABSTRACT
OBJECTIVES: The purpose of this study was to evaluate the longer-term efficacy of ultrasound (US)-guided radiofrequency ablation (RFA) for treating locally recurrent papillary thyroid cancer (PTC).
METHODS: We retrospectively reviewed 29 patients who underwent RFA for 46 recurrent PTC between September 2008 and April 2012 and were subsequently followed up for at least 5?years. Follow-up included size change on US and thyroglobulin (Tg) level at 1, 3, 6, and 12?months and every 6-12?months thereafter. Any complications were reported during follow-up.
RESULTS: The mean follow-up duration after RFA was 80?짹?17.3?months (range, 60-114?months). Tumor volume decreased significantly, from 0.25?짹?0.42?mL before ablation to 0.01?짹?0.08?mL at the final evaluation (p?
CONCLUSIONS: RFA seems to be an effective minimally invasive therapy for the treatment of locally recurrent PTC even in the longer-term period. KEY POINTS: ? RFA is an effective local control treatment option for recurrent PTCs even in the longer-term period with mean tumor VRR of 99.5% and the complete disappearance of the treated tumors in 91.3%. ? The mean serum Tg level decreased significantly after RFA and biochemical remission rate was 51.7%. ? No delayed complication after RFA for local recurrent PTC.
