Administración de radioyodo en cáncer diferenciado de tiroides bajo régimen hospitalario. A propósito de la implementación del aislamiento de radioyodoterapia en un hospital regional.

Introduction: Differentiated thyroid cancer (CDT) presents an increase in global levels. The selective use of radioiodine therapy (RAI) is a pillar of its treatment. Its therapeutic effect is due to beta radiation, while gamma makes hospitalization necessary to limit exposure. Aim: To describe the safety treated with RAI inpatients and the functioning of the radioactive isolation rooms of our center. Materials and Method: Retrospective descriptive study. All patients diagnosed with CDT who required RAI therapy under a hospital regimen at the Regional Hospital of Talca (HRT) between August-December 2018 were included. Results: During the period described, 10 patients were treated. The median dose of RAI administered was 100 mCi (range: 50-150 mCi). The average of hospitalization was 28 hours, being discharged when reporting an absorbed dose rate < 70 µSv/h at 1 meter, giving the patient instructions, so that they follow to minimize the risk of irradiation or contamination of people in their environment. Conclusions: Our RAI administration protocol allows patients with CDT to be treated safely. The radioactive isolation rooms could cover 100% of the demand for RAI therapy in CDT at the local level.
