Long-Term Follow-up of Patients With Autonomous Thyroid Nodules Treated With Radioiodine.

Purpose: This article aims to describe the presentation of Plummer disease and its evolution after radioiodine treatment and determine factors that may influence treatment efficacy.

Patients And Methods: The sample included retrospective medical records of 165 adult patients with toxic nodular goiter treated with radioiodine between 1997 and 2017, followed up at a single thyroid center.

Results: The efficacy of treatment with a single dose of radioiodine was higher than 90%.

Low iodine diet does not improve the efficacy of radioiodine for the treatment of Graves' disease.

Objective: Consuming a low-iodine diet (LID) is a widely accepted practice before administering radioiodine (131I) to evaluate and to treat thyroid disease. Although this procedure is well established for the management of patients with differentiated thyroid cancer, its use in patients with benign disease is unclear. So, we aimed to evaluate the influence of a LID on the outcome in patients with Graves' disease (GD) treated with 131I.
