Abstract/OtherAbstract:
Background: Surgical management of symptomatic benign thyroid nodules in patients with previous lobectomy poses a dilemma for physicians. Radiofrequency (RF) ablation may provide a treatment option that avoids surgery and preserves thyroid function. We evaluated whether RF ablation of benign thyroid nodules affects thyroid functions in patients with previous lobectomy. Methods: A total of 11 patients with 14 thyroid nodules were enrolled using the following criteria: (1) having a predominantly solid nodule; (2) reporting pressure symptoms or cosmetic problems; (3) cytological confirmation of benignancy; (4) no malignant features detected using ultrasound; (5) serum thyroid hormone and thyrotropin (TSH) levels within normal limits; and (6) refusal of or ineligibility for surgery. Thyroid functions, nodule volumes, and clinical concerns were evaluated before RF ablation and during follow-up after RF ablation. Results: The mean follow-up duration after RF ablation was 43.7 ± 30.7 months (range, 7-92 months). The mean nodule volume was 9.7 ml (0.9-57.6 ml) before the procedure, and was significantly decreased at the last follow-up (P < 0.001) with a mean volume reduction rate of 87.2 %. The mean symptom score (P = 0.003) and cosmetic score (P = 0.003) were both significantly decreased at the last follow-up. Levels of TSH, free thyroxine, and triiodothyronine were not significantly different prior to treatment and at the last follow-up (P > 0.05), and remained normal in all cases. Conclusions: In patients with previous lobectomy, RF ablation should be considered as a first-line treatment for symptomatic benign thyroid nodules to preserve thyroid functions.
