Popis: Abstract Objectives To assess whether increasing radioactive iodine dose can increase treatment efficacy in Graves’ disease. Methods A prospective study was conducted, including 106 patients receiving 20 mCi (740 MBq) radioactive iodine (RAI), compared with a retrospective data, including 113 patients receiving 10–15 mCi (370–555 MBq) RAI. Remission and failure rates were evaluated at 6 months post-RAI. Statistical analysis was performed using logistic regression and Kaplan–Meier curves. Results Patients receiving 20 mCi RAI demonstrated a significantly higher remission rate compared to the 10–15 mCi group (82.1% vs 66.4%, p = 0.009). Median time to remission was shorter in the 20 mCI group (3 vs 4 months, p = 0.002). Hypothyroidism at 6 months was more prevalent in the 20 mCi group (67% vs 53%, p = 0.03). Larger thyroid size (> 60 g) was associated with treatment failure (p = 0.02). Conclusions Higher dosage (20 mCi) RAI showed superior efficacy in achieving remission compared to lower dosages (10–15 mCi) in Graves’ disease treatment.
