It is well known that as one of the time-tested safe and effective treatment modalities, RAI holds its superiority in hyperthyroidism control, particularly for patients who are not indicated for antithyroid drugs (ATDs) or surgery. We read, with great interest, the recent article by Kitahara and colleagues  published in “JAMA Internal Medicine” reporting the results of a “modest” positive association between greater organ-absorbed doses of radioactive iodine (RAI) and the risk of death from solid cancer.
We note that the authors did a great job in the field of low-dose radiation biological effects as a result of a large cohort size, a long-term follow-up, and an innovative method used to estimate organ- and tissue-absorbed doses. However, we are afraid that the conclusion might lead to anxiety and doubt of the value of RAI in hyperthyroidism from a simple glimpse of the conclusion. In fact, some essential issues should be noted for further discussion in case of any...
