Abstract

Abstract : Objectives: To preliminarily evaluate the safety, effectiveness, and feasibility of microwave ablation (MWA) for substernal goiter (SSG) in select patients and to provide a relevant treatment reference for further studies. Methods: From April 2017 to December 2017, 10 patients with SSG were treated by MWA. All patients were followed for at least 3 months to observe the therapeutic effects and complications. Therapeutic effects were assessed at follow‐up for the relief of patients' symptoms, resolution of the cosmetic grade, and volume reduction rate (VRR) of SSG. Possibly related factors for the 3‐month VRR of the nodules were analyzed. Results: The study included 9 female patients and 1 male patient with a mean age ± SD of 56.8 ± 10.1 years (range, 34–70 years). The mean volume of the nodules was 52.9 ± 27.9 mL (range, 23.7–122.6 mL). The nodule volume was significantly reduced at the 3‐month follow‐up (17.5 ± 9.5 mL; P < .05). The mean 3‐month VRR of the index nodule was 66.7% ± 7.1%. A higher ablated portion‐to‐nodule ratio 1 day after MWA predicted a higher 3‐month VRR (Spearman r = 0.646; P = .044). The mean symptom score (from 4.5 ± 1.7 to 1.5 ± 1.0; P = .005) and cosmetic grade (from 3.3 ± 0.5 to 2.2 ± 0.4; P = .004) declined significantly 3 months after the procedure. No complications or unexpected side effects were observed. Conclusions: Our preliminary results support the effectiveness and safety of MWA for local control of SSG. This technology can be applied in select patients with SSG who are ineligible for surgery.
