bull Radiotherapy is a useful low toxicity treatment for bone pain in patients with metastases from prostate cancer
bull Single fraction external beam treatments are as effective at pain relief as longer schedules
bull Systemic bone-seeking isotopes in the past have shown both pain relief and a delay to the next skeletal event

Conclusions
bull Radiotherapy is a useful low toxicity treatment for bone pain in patients with metastases from prostate cancer
bull Single fraction external beam treatments are as effective at pain relief as longer schedules
bull Systemic bone-seeking isotopes in the past have shown both pain relief and a delay to the next skeletal event
bull Radium-223 is a significant advance in isotope treatment not only causing effective pain relief and delaying further pain but also prolonging survival
Radium-223

bull In prostate cancer ndash investigations have shown it is possible to detect early radiological signs of impending SCC in asymptomatic patients with or without bone pain

Conclusions
bull Radiotherapy is a useful low toxicity treatment for bone pain in patients with metastases from prostate cancer
bull Single fraction external beam treatments are as effective at pain relief as longer schedules
bull Systemic bone-seeking isotopes in the past have shown both pain relief and a delay to the next skeletal event
bull Radium-223 is a significant advance in isotope treatment not only causing effective pain relief and delaying further pain but also prolonging survival
