Research summary
Prostate cancer is the most common form of non-skin cancer in men and can spread actively and aggresively to other parts of the body (metastases). The most common site for the cancer to spread to (in advanced prostate cancer) is the skeleton. Approximately 50% of patients with bone cancer (spead from prostate cancer) die of prostate cancer within 30 months, and 80% within 5 years.
Prostate cancer cells are stimulated by hormones, in particular testosterone. Conventional androgen deprivation therapy (ADT) in patients with bone cancer aims to reach castration levels of testosterone which can be initially effective at controlling the cancer in the bone. However, the majority of patients soon become castration resistant, i.e. progression occurs even at castration levels of testosterone. At this stage, the disease can interchangeably be referred to as either CRPC (castration resistant prostate cancer) or the older term hormone-refractory prostate cancer (HRPC).
This observational study called REASSURE is to assess the incidence of second cancers among patients with metastatic Castration Resistant Prostate Cancer (mCRPC) receiving Radium-223 in routine clinical practice (i.e. cancer progression). The short and long term safety profile of Radium-223, which selectively targets bone cancer with high-energy, short-range alpha-particles will also be evaluated. In addition bone marrow suppression, overall survival and pain-related data will be collected.
