ABSTRACT
Objective To assess the effectiveness and safety of ultrasound-guided percutaneous radiofrequency ablation (RFA) for nonsurgical treatment of metastatic lymph nodes (LNs) in the neck from papillary thyroid carcinoma (PTC). Methods Totally 45 PTC patients who had been treated with total thyroidectomy and radioiodine therapy were enrolled in this retrospective study. A total of 71 metastatic LNs in the neck from PTC were confirmed by percutaneous biopsy. Follow-up consisted of conventional ultrasound,contrast-enhanced ultrasound,and thyroglobulin (Tg) measurement 1,3 and 6 months after RFA and then every 6 months. Results All 45 patients were successfully treated,without immediate or later major complications occurred. During the follow-up [(23±5) months;range12-30 months)],there was no evidence of recurrence at ablated sites. The mean volume reduction ratio (VRR) was significantly reduced during the follow-up. Significant differences in the VRR were found between every two follow-up visits (P<0.001). Furthermore,46 metastatic LNs (64.8%) completely disappeared and 25 metastatic lymph nodes (35.2%) remained as small scar-like lesions at the last follow-up visit. After RFA,mean serum Tg level decreased from (11.3±6.3)ng/ml (range0.8-19.4 ng/ml) to (1.3±0.9)ng/ml (range0.2-3.9 ng/ml) at the last follow-up visit (P<0.001). Conclusion Ultrasound-guided percutaneous RFA is a safe and effective therapy for patients with cervical LNs metastasis from PTC.
