Abstract
Purpose
Paget disease is commonly asymptomatic and discovered when an imaging test is performed for another clinical indication or when elevated serum alkaline phosphatase is found. Bone pain usually appears late in the disease process and is only present in a minority of patients. For diagnosis, X-ray and bone scan are the most recommended imaging methods; radionuclide imaging of the skeleton has become the standard, since it is the most sensitive test for detecting increased bone activity. For treatment, either bisphosphonates or calcitonin are recommended.
Methods
We present a 74-year-old patient diagnosed with prostate cancer in 2001 who developed bone metastases concomitant with a Paget bone disease.
Results
This patient received treatment with Ra-223, having stable disease in bone scan and no relevant toxicities.
Conclusions
There is no clinical experience with Ra-223 and Paget disease, since it is characterized classically as a high bone turnover disease and therefore there is no rationale to administer a drug that has a high bone affinity. Nevertheless, Ra-223 is not contraindicated.
