/sup 125/I therapy in Graves' disease. Long-term results in 355 patients

Journal Article · · Ann. Intern. Med.; (United States)
Because of the physical and radiobiologic differences between /sup 125/I and /sup 131/I, a trial using /sup 125/I to treat hyperthyroidism was undertaken in the hope of controlling hyperthyroidism without causing subsequent hypothyroidism. Three hundred fifty-five patients with diffuse toxic goitres were treated and have been under review for an average of 49.4 months: 63.4 percent are euthyroid, 33.5 percent are hypothyroid, and 3.1 percent remain hyperthyroid. Different groups of patients received a wide range of doses of /sup 125/I (4.0 to 56.0 mCi), and the lowest incidence of hypothyroidism (23 percent) was in the group that received between 6.0 and 10.5 mCi. Sixty-three percent of the patients whose initial dose was greater than 20.0 mCi are hypothyroid. Persistent hyperthyroidism was common in patients who received small doses. Because of the high incidence of posttreatment hypothyroidism in this series and because /sup 131/I has stood the test of time, we believe that /sup 131/I is the radionuclide of choice for the routine treatment of hyperthyroidism.
