Abstract

Purpose: Patients with toxic adenomas (TAs) that are too large to undergo radioactive iodine (RAI) treatment aimed at resolving hyperthyroidism and/or relieving mechanical pressure symptoms are referred to surgery. This prospective study aimed to assess the outcomes of combining laser ablation (LA) plus RAI vs lobectomy to treat large TAs in terms of clinical efficacy and the health-related quality of life (HRQoL).

Patients and methods: Patients with TAs of volumes greater than 20 mL and a calculated therapeutic activity exceeding 600 Mbq were randomly assigned to undergo LA + RAI (Group A) or lobectomy (Group B). The HRQoL was assessed using 12-item Short Form Health Survey questionnaire before and 6 months after treatment.

Results: Twenty-seven patients entered the study. After completing treatment, patients in Group A showed a TA reduction by a mean of 68% compared to baseline. Two of 14 patients (14.3%) in Group A and 2 of 13 (15.4%) in Group B became subclinically hypothyroid, whereas the remaining patients were euthyroid. HRQoL significantly improved in both groups after treatment.

Conclusions: For patients with large TAs, a combination of LA and RAI is a feasible alternative to surgery. Similar to surgery, LA + RAI resolves the mechanical discomfort induced by nodule pressure and effectively treats the hyperthyroidism. This procedure also avoids the potential complications associated with surgery while guaranteeing a similar HRQoL benefit.
