Radium-223 Chloride

چکیده
In the last few years, the treatment of castration-resistant prostate carcinoma (CRPC) has changed completely. The approval of docetaxel and subsequent investigation in this field have led to development of new agents that have demonstrated an improvement in overall survival in the post-docetaxel setting, such as cabazitaxel and abiraterone. Radium-223 chloride is a radioisotope that has recently shown efficacy after docetaxel and in patients unfit for docetaxel, with improvements in overall survival and the time to the first skeletal-related event, compared with placebo, without increasing toxicity. These findings have made this agent a new option for treatment of these patients in the near future.

Radium 223 dichloride for prostate cancer treatment
Prostate cancer is the most common malignant disease in men. Several therapeutic agents have been approved during the last 10 years. Among them, radium-223 dichloride (Xofigo®) is a radioactive isotope that induces irreversible DNA double-strand breaks and consequently tumor cell death. Radium-223 dichloride is a calcium-mimetic agent that specifically targets bone lesions. Radium-223 dichlorid...
متن کاملRadium-223 chloride: Extending life in prostate cancer patients by treating bone metastases.
The treatment scope for patients with metastatic castrate-resistant prostate cancer (mCRPC) is rapidly expanding. On May 15, 2013, the U.S. Food and Drug Administration (FDA) approved radium-223 chloride ((223)RaCl2) for the treatment of mCRPC patients whose metastases are limited to the bones. Radium-223 is an α-emitting alkaline earth metal ion, which, similar to calcium ions, accumulates in ...
متن کاملHematologic Safety of Radium-223 Dichloride: Baseline Prognostic Factors Associated With Myelosuppression in the ALSYMPCA Trial.
BACKGROUND Myelosuppression is common in patients with progressive castration-resistant prostate cancer and bone metastases. Radium-223 prolongs overall survival in these patients but may cause myelosuppression; understanding risk factors will improve clinical decision making. We describe hematologic safety of radium-223 in ALSYMPCA and post hoc analyses identifying patients at increased risk f...
متن کاملChemotherapy following radium‐223 dichloride treatment in ALSYMPCA
BACKGROUND Radium-223 prolongs overall survival in patients with castration-resistant prostate cancer (CRPC) and symptomatic bone metastases, regardless of prior docetaxel. Whether or not chemotherapy can be safely administered following radium-223 treatment is of clinical importance. An exploratory analysis of prospectively collected data, from the ALSYMPCA (ALpharadin in SYMptomatic Prostate ...
متن کاملRadium-223 chloride: a potential new treatment for castration-resistant prostate cancer patients with metastatic bone disease
BACKGROUND Radium-223 chloride ((223)Ra; Alpharadin) is an alpha-emitting radioisotope that targets areas of osteoblastic metastasis and is excreted by the small intestine. When compared with beta-emitters (eg, strontium-89, samarium-153), (223)Ra delivers a high quantity of energy per track length with short tissue penetration. OBJECTIVE This review describes the mechanism, radiobiology, and...
