Abstract

Background: Radiofrequency ablation (RFA) is a minimally invasive treatment that has been increasingly applied in the management of benign thyroid nodules. However, data regarding its effectiveness and safety in provincial hospitals in Vietnam remain limited. Objectives and Methods: A prospective, descriptive, single-arm interventional study was conducted on 37 patients with 41 benign thyroid nodules (Bethesda II) treated with ultrasound-guided RFA at Binh Duong General Hospital from June 2024 to June 2025. Evaluated parameters included symptom score, cosmetic score, nodule volume, volume reduction ratio (VRR), pain severity, and complications at baseline, 1 month, and 3 months after treatment. Results: After RFA, the median symptom score decreased from 4 at baseline to 2 at 1 month and remained unchanged at 3 months (p < 0.01). The cosmetic score significantly improved from 4 to 1 at 3 months (p < 0.01). Median nodule volume decreased from 7.76 ml to 4.51 ml at 1 month and to 2.88 ml at 3 months, with median VRRs of 29.6% and 46.6%, respectively. Most patients reported mild to moderate pain. No complications were observed in 90.3% of cases, and recorded complications were mild and transient. Conclusions: Radiofrequency ablation is an effective, safe, and minimally invasive treatment for benign thyroid nodules and is feasible for implementation in provincial hospital settings.
