Abstract

Objectives: Evaluating the factors related to the results of treatment of benign thyroid nodule with radiofrequency ablation. Methods: This is retrospective case series conducted at the Department of Thoracic and Vascular Surgery, Thu Duc city hospital. Results: From 5/2018 to 5/2023, there were 70 cases of benign thyroid nodule treated with radiofrequency ablation, the mean age 45.8 ± 14.5 years (22 – 75 years); 57 females (81.4%) and 13 males (18.6%). The nodule location is distributed in the right and left lobes, accounting for nearly equal proportions of 51.4% and 45.7%, respectively, with 2 cases located in the isthmus area (2.9%). The average diameter of thyroid nodule 30.37 ± 8.58mm (20-54ml), the mean volume of thyroid nodule 8.39 ± 7.95ml (3.3 – 29.9ml). Most thyroid nodules are solid, 62.9%, the remaining mixed and cystic forms are 32.8% and 4.3%, respectively. The energy and duration of ablation are proportional to size of thyroid nodule (p < 0.05). The mean volume reduction rate of thyroid nodules tends to increase gradually after intervention, highest in the first month at 36.88% and reaches a maximum of 75.04% at 6 months after ablation; The average volume reduction rate in groups with different solid tissue at 1 month after ablation was significantly different (p < 0.05). Conclusion: The energy and duration of ablation are proportional to thyroid nodule size. The rate of thyroid nodule volume reduction and the proportion of solid tissue in the thyroid nodule are also factors that affect the rate of thyroid nodule volume reduction after radiofrequency ablation.
