Abstract: Background: This study aims to evaluate the effectiveness and cure rate of individualized radioiodine therapy in patients diagnosed with Graves’ disease and toxic adenoma.Methods: A total of 11 patients with toxic adenoma and 20 patients with Graves’ disease were enrolled inthe study. Radioiodine activities were individually calculated using patient-specific data and a mathematicalmodel to deliver target absorbed doses of 300 Gy for toxic adenoma and 200 Gy for Graves’ disease. Themean administered radioactive iodine (RAI) activity was 826 ± 124 MBq for patients with toxic adenomaand 541 ± 215 MBq for those with Graves’ disease.Results: At the 3-month follow-up, 35% of patients with Graves’ disease and 54.6% of those with toxicadenoma reached a euthyroid state. Hypothyroidism occurred in 65% of Graves’ patients and 45.4% oftoxic adenoma patients; all began thyroid hormone replacement therapy and achieved euthyroid status bythe 6-month follow-up.Conclusion: Dosimetry-based RAI therapy achieved complete remission within 3 months following a singleadministration of 131I, with no patients requiring a second course of RAI therapy. In contrast to empirical treatment protocols, individualized therapy enhances safety, minimizes risk, and improves clinical outcomes.Cite this article as: Abuqbeitah M, Yeyin N, Akyol S, Uslu-Beşli L, Demir M.
