- Abstract
Purpose: To evaluate the safety and efficacy of ultrasound-guided low-power microwave ablation (MWA) for the treatment of papillary thyroid microcarcinoma (PTMC) with a 3-year follow-up.Methods: A total of 21 nodules diagnosed as PTMC from the 15 patients were performed with MWA at a power of 20 W. The images of the nodules were recorded by ultrasound before MWA and 1, 3, 6, 12 months after MWA, and every 6 months thereafter, respectively. The volumes of the nodules were compared before MWA and at each follow-up point after MWA. The volume reduction rate (VRR) of nodules was also calculated.Results: The mean volume of the nodules was 134.3 ± 129.8 mm3 initially (the range was 7.4-423.8 mm3), which decreased significantly to 2.3 ± 10.5 mm3 (the range was 0-48.1 mm3) of the ablation area (<italic>P</italic> = 0.000) at the follow-up point of 36 months with a mean VRR as 98.78 ± 5.61% (the range was 74.28-100%). During the follow-up period (the range was 36-48 months), 20 of the 21 nodules were completely absorbed and no recurrent nodule was found.Conclusions: After a long-term follow-up of 3 years, the low power MWA showed a good safety and efficacy for the treatment of PTMC. In addition to surgery and active surveillance, MWA might be another alternative for patients with PTMC.
