[Results of treatment of hyperthyroidism with 125-iodine].

About 100 patients with hyperthyroidism and diffuse goiter (gland weight not more than 60 g) were treated with an individually calculated dose of 125-Iodine. After a follow-up time between 1.5 and 2 years there are the following results: 82% of the patients are euthyroid and 18% are still hyperthyroid. Relapse rate was 10%. More than 30% of the residual or relapse hyperfunctions were T3 toxicosis. The status of 125-Iodine in the treatment of thyrotoxicosis is discussed with regard to the necessity of a "destructive" therapy in the major part of the patients. Published results of 125-Iodine therapy are summarized.
