To compare the outcomes of different methods in prescribing the optimal dose of radioactive iodine (131I) for the treatment of hyperthyroidism, we retrospectively analyzed 52 patients with toxic diffuse goiter. They received single dose of 131I for the treatment of hyperthyroidism. In addition, all of them met the following criteria: 1) symptoms and signs of hyperthyroidism; 2) elevated blood triiodothyronine (T3) and thyroxin (T4) by radioimmunoassay (RIA) method; 3) diffuse goiter with increase of uptake proved by thyroid scintiscan; 4) only one dose of 131I was given during the follow-up period; 5) well-documented thyroid function test in the medical chart during the follow-up period (6 months, 1 year, 2 years and 5 years after 131I therapy). The enrolled patients were divided into estimated and calculated group. The dose of 131I in the calculated group was obtained from the measurement of size and 131I uptake of thyroid gland. The dose of 131I in the estimated group was prescribed according to the size of thyroid gland by physical examination, and the association with cardiac arrhythmia, congestive heart failure, or ischemic heart disease. The mean doses of 131I were 4.8 +/- 1.4 mCi and 7.0 +/- 1.1 mCi in the calculated and estimated group respectively. In this study, there were no significant difference in the incidence of euthyroidism, hyperthyroidism, and hypothyroidism between these two groups in thefollow-up period after 131I therapy. In view of simplicity and time-saving, it is a practical choice to prescribe the dose of 131I therapy for toxic diffuse goiter according to the size of thyroid gland and the associated cardiac condition.
