Abstract
Radiofrequency ablation (RFA) has been recently adopted into the practice of thyroidology in the United States, although its use as an alternative to traditional thyroid surgery in Asia and Europe came near the turn of the 21st century. In the United States, only a few studies with small sample sizes have been published to date. We examined outcomes of benign thyroid nodules treated with RFA from 2 North American institutions.
Conclusion
A total of 233 nodules were included. The median and interquartile range of volume reduction rate (VRR) at 1, 3, 6, and 12 months were 54% [interquartile range (IQR): 36%–73%], 58% (IQR: 37%–80%), 73% (IQR: 51%–90%), and 76% (IQR: 52%–90%), respectively (P<0.001). Four patients presented with toxic adenomas. All patients were confirmed euthyroid at 3-month postprocedure follow-up. Two patients developed temporary hoarseness of voice, but no hematoma or nodular rupture occurred postprocedure. Elastography was significantly associated with VRR. Compared with soft nodules, stiff nodules were more likely to have a lower VRR (odds ratio: 11.64, 95% confidence interval: 3.81–35.53, P<0.05), and mixed elasticity was also more likely to have a lower VRR (odds ratio: 4.9; 95% confidence interval: 1.62–14.85, P
