Reviewing therapy with radioisotopes for pain bone metastasis and its possible evolution

Abstract

Introduction: The therapy with radioisotopes is widely used, its beginnings were focused on thyroid pathologies treatments.  Over the years, the radiopharmaceuticals and/or radioisotopes have had their usage increased, to be used on painful bone metastasis. Material and Methods: A bibliographic search was conducted in the major health Science basis to evaluate what the therapies have to offer for patients in this condition. Results: Currently there are only two available materials in Brazil, the Sm153 that is national production, and Ra223, that is imported. Outside Brazil we can find a variety of materials that have already been approved by the Sanitary Organization in other countries, even though we are not authorized to use them due to Brazilian Regulation and production issues. Conclusion: Besides the diversity of materials that could be used, dosimetry systems must be implemented in order to have a more efficient treatment and to have an accurate administrated activities to patients.
