Abstract

The administration of a radionuclide in unsealed source whose radiation will destroy cells that have selectively accumulated product is called radiometabolic therapy. 
The management of bone pain is a major problem, particularly in cases of breast or prostate where the presence of metastases can remain compatible with long-term survival of cancer patients. 
In this context, the radiometabolic therapy reduces the pain secondary to bone metastases, in association or not with analgesics. 
This technique is rarely prescribed as first-line. 
It can also be combined with external beam radiotherapy or chemotherapy, if clinical conditions permit (due to the increased risk of hematologic toxicity). 
In this setting, the currently used substances are Metastron® and Quadramet®. 
Recently, a new product, radium chloride (or Alpharadin®) has shown efficacy in bone metastases from prostate cancer, particularly in terms of bone pain palliation, but also of increased overall survival. 
In addition, this product has virtually no hematologic toxicity.
