radium 223 cancer

Chad R Ritch, Michael S Cookson
Docetaxel based chemotherapy showed survival benefit and emerged as the mainstay of treatment for castration resistant prostate cancer (CRPC) in 2004. However, therapeutic options have expanded rapidly since 2011. The spectrum of new agents is broad and includes drugs that target the androgen axis (enzalutamide, abiraterone), immunotherapy (sipuleucel-T), bone seeking radionuclides (radium-223), and second line chemotherapy (cabazitaxel). In addition, new agents have been developed to reduce skeletal related events (denosumab)...

Radiopharmaceuticals used in the treatment of castrate-resistant prostate cancer are reviewed herein with an emphasis on sequential and combination therapies. Four bone-seeking radiopharmaceuticals had been approved in the United States. Three of these are β-emitters (phosphorus-32, strontium-89, samarium-153-ethylenediaminetetramethylene-phosphonic acid) that are approved for palliative purposes. One α-emitter (radium-223 [Ra]) is approved for prolongation of survival in bone metastatic castrate-resistant prostate cancer...

The development of metastatic castration-resistant prostate cancer (mCRPC) signals the terminal disease phase. The preceding hormone-dependent disease setting is effectively managed with androgen deprivation therapy. This foundation of treatment has a high rate of biochemical and clinical response and meaningful clinical benefit but is finite in duration as most cancers will progress to castration resistance. Historically, treatment for mCRPC entailed androgen receptor (AR) inhibitors (nilutamide, flutamide, bicalutamide), nonspecific steroidal biosynthesis inhibitors (ketoconazole, itraconazole), steroids (prednisone, diethylstilbesterol, dexamethasone), or palliative chemotherapy (mitoxantrone, estramustine), but none of these strategies impacted survival...

OBJECTIVE: To provide an overview of the efficacy, tolerability, drug interactions, dosing, and administration issues associated with enzalutamide, abiraterone, and radium-223 for the treatment of patients with metastatic castration-resistant prostate cancer (mCRPC). DATA SOURCES: MEDLINE and Web of Science were used to search for relevant articles using a key-word search (enzalutamide, abiraterone, radium-223, and phase 3). No restriction was placed on the date of publication...

PURPOSE: Therapy with the alpha-emitter radium-223 chloride ((223)Ra) is an innovative therapeutic option in patients with metastasized, castration-resistant prostate cancer. However, radiotherapy can lead to hematopoietic toxicity. The aim of this study was to determine if (223)Ra therapy induces an impairment of cellular antimicrobial immune responses. METHODS: In 11 patients receiving (223)Ra treatment, lymphocyte proliferation and the production of pro- and anti-inflammatory cytokines (interferon-γ and interleukin-10) were determined, using lymphocyte transformation testing and ELISpot, respectively...

Prostate cancer is a major public health problem worldwide, still remaining the most common cancer among elder males in both Europe and USA, being responsible for approximately 30,000 deaths in USA in 2014. Nowadays, after decades of basic research, novel treatment options have emerged focusing on men suffering from metastatic castration-resistant prostate cancer improving overall survival. It is also estimated that more than 90% of such patients develop bone metastasis, resulting in a significant increase in morbidity and mortality...

Bone metastases affect the majority of patients with castration-resistant prostate cancer (CRPC), resulting in significant morbidity and mortality. This review describes the current therapies available for the management of CRPC patients with bone metastases. Areas covered: Studies on the use of currently available therapeutic approaches for palliating pain, delaying skeletal-related events (SREs) and prolonging survival in CRPC patients with bone metastases have been examined. PubMed database was searched in May 2016 starting with the following keywords: ('castration-resistant prostate cancer' OR 'CRPC') AND 'bone metastases', and approximately 270 results were retrieved...

PURPOSE: We retrospectively evaluated the utility of (68)Ga-PSMA-11 PET for planning (223)RaCl2 therapy of patients with metastatic prostate cancer and its impact on the therapeutic response as determined by PSA and ALP, as well as the correlation of PSA changes with the results of PSMA-PET, follow-up scans. METHODS: Sixty-three patients with a median age of 73 years who underwent a total of 307 cycles of therapy with (223)RaCl2 were analyzed. In thirty-one patients bone scans and radiological imaging was performed for pre therapeutic imaging (group 1)...

BACKGROUND: Radium-223 has shown clinical efficacy in metastatic castration-resistant prostate cancer. Despite improvement in quality of life and survival, practice patterns and utility of this agent outside the context of clinical trials have not been fully characterized. The primary objective in this study was to evaluate variables associated with completion of 5 to 6 radium-223 doses. PATIENTS AND METHODS: We conducted retrospective analyses of patients who received radium-223 (n = 135)...

Bone metastases ultimately result from a complex interaction between cancer cells and bone microenvironment. However, prior to the colonization of the bone, cancer cells must succeed through a series of steps that will allow them to detach from the primary tumor, enter into circulation, recognize and adhere to specific endothelium, and overcome dormancy. We now know that as important as the metastatic cascade, tumor cells prime the secondary organ microenvironment prior to their arrival, reflecting the existence of specific metastasis-initiating cells in the primary tumor and circulating osteotropic factors...

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 for hematologic toxicity. PATIENTS AND METHODS: Hematologic parameters and adverse events were analyzed...

INTRODUCTION: A number of drugs have been shown to extend life expectancy in castration-resistant prostate cancer (CRPC). Skeletal related events (SREs) secondary to bone metastases cause significant morbidity for men with CRPC. The α-emitting radiopharmaceutical radium-223 dichloride has been shown to improve overall survival, time to symptomatic skeletal events (SSEs) and quality of life in CRPC. AREAS COVERED: The development of radium-223 from pre-clinical studies to the evidence of efficacy and safety from a phase 3 trial is discussed as well as its pharmacokinetics and metabolism...
