Deep dives
History of Radioiodine Therapy
Radioiodine therapy began with the idea of using radioactive iodine, specifically I-131, for treating hyperthyroidism. Saul Hertz, inspired by a lecture, proposed this treatment in the 1930s. By 1941, the first patient, Elizabeth D., was successfully treated, marking the birth of nuclear medicine and targeted radionuclide therapy.
Development and Testing of Isotopes
The research teams at MIT and the thyroid clinic at Massachusetts General Hospital collaborated to create iodine isotopes like I-128, I-130, and I-131. These isotopes were used as tracers and eventually as treatments for thyroid diseases. The longer half-lives of the isotopes made them effective for treatment, allowing time for proper administration and targeting of thyroid tissue.
Clinical Trials and Successful Outcomes
Initial trials in rabbits showed significant uptake of radioactive iodine by hyperplastic thyroid glands. Human trials followed, with patients experiencing improved conditions after radioiodine therapy. The success of the treatment led to more patients being treated, including those with thyroid cancer, with positive outcomes and significant advancements in effective therapy.
Legacy of Saul Hertz and Radioiodine Therapy
Despite personal conflicts and academic disputes, the legacy of Saul Hertz in developing radioiodine therapy remains significant. His work paved the way for targeted radionuclide therapy and established an effective treatment for thyroid diseases. Honors like the Dr. Saul Hertz Lifetime Achievement Award recognize his contributions to medical science and the enduring impact of his innovative treatment.
This 2019 episode examines thyroid disease through history, and the physics lecture heard by Saul Hertz in the 1930s that changed the treatment of hyperthyroidism forever.
