BACKGROUND: Progressive metastatic castration-resistant prostate cancer is a highly lethal disorder and new effective therapeutic agents that improve patient outcomes are urgently needed. Lutetium-177 [177 Lu]-PSMA-617, a radiolabelled small molecule, binds with high affinity to prostate-specific membrane antigen (PSMA) enabling beta particle therapy targeted to metastatic castration-resistant prostate cancer. We aimed to investigate the safety, efficacy, and effect on quality of life of [177 Lu]-PSMA-617 in men with metastatic castration-resistant prostate cancer who progressed after standard treatments...

Background: Treatment selection for men with metastatic castration-resistant prostate cancer (mCRPC) has become increasingly challenging with the introduction of novel therapies at earlier disease stages. The purpose of this study was to identify prognostic factors for overall survival (OS) and PSA response in patients with mCRPC treated with cabazitaxel. Results: 224 mCRPC patients were included in the current analysis. In multivariable analysis, WHO performance status, baseline hemoglobin, alkaline phosphatase and albumin were all significantly associated with OS...

BACKGROUND: An important clinical question of great interest to clinicians is how to best sequence androgen receptor targeted agents (ARTAs) and chemotherapy for metastatic castration-resistant prostate cancer (mCRPC), but the answer is still unclear. MATERIALS AND METHODS: To evaluate and compare the clinical outcomes of ARTA and docetaxel (DTX) as second-line treatment in the post first-line ARTA, we conducted a retrospective analysis of chemotherapy-naive mCRPC patients who had received sequential treatment with ARTA followed by another ARTA (ARTA-ARTA) or ARTA followed by DTX (ARTA-DTX)...

Abiraterone acetate has established a major role in the treatment paradigm of metastatic castration-resistant prostate cancer ever since pivotal trials, COU-AA-301 and COU-AA-302, have shown benefit in both the second-line and first-line (post- and pre-chemotherapy) setting, respectively, with improvement in overall survival as well as secondary end points such as prostate-specific antigen (PSA) and radiographic response rates, time to PSA progression, and progression-free survival. There has been a lot of interest and emphasis in the evaluation of patient-related outcomes (PROs) as it relates to quality of life, pain, adverse events, fatigue, and among others, in the use of different agents that have been shown to improve survival...

BACKGROUND: Galeterone is a multi-targeted agent with activity as a CYP17 inhibitor, androgen receptor antagonist, and also causes androgen receptor degradation. It has shown meaningful anti-tumor activity with a well-tolerated safety profile in patients with castration-resistant prostate cancer (CRPC) in phase I and II studies; however, the efficacy of currently approved CRPC therapies after treatment with galeterone is unknown. In this study, we evaluate prostate specific antigen (PSA) response of non-protocol therapies following galeterone in a subset of patients treated on the Androgen Receptor Modulation Optimized for Response (ARMOR) 2 study...

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)...

BACKGROUND: Treatment of metastatic castration-resistant prostate cancer (mCRPC) with chemotherapy improves disease control and survival in fit older men (age 65+) but its impact on function is not clear. We hypothesized that chemotherapy would impair daily function in older men with mCRPC. METHODS: Men aged 65+ with mCRPC starting chemotherapy or abiraterone were enrolled in this prospective observational pilot study. Daily function was evaluated with the OARS Instrumental Activities of Daily Living (IADL) scale...

PURPOSE: Prostate-specific antigen (PSA) kinetics, and more specifically a ≥ 30% decline in PSA within 3 months after initiation of first-line chemotherapy with docetaxel, are associated with improvement in overall survival (OS) in men with metastatic castration-resistant prostate cancer (mCRPC). The objective of this analysis was to evaluate post-treatment PSA kinetics as surrogates for OS in patients receiving second-line chemotherapy. PATIENTS AND METHODS: Data from a phase III trial of patients with mCRPC randomly assigned to cabazitaxel plus prednisone (C + P) or mitoxantrone plus prednisone were used...

BACKGROUND: About 20% of patients with prostate cancer have an ECOG performance status (PS) 2 at diagnosis. We investigate if current treatment options for castration-resistant prostate cancer (CRPC) may decrease the risk of death even in patients with ECOG PS of 2. METHODS: PubMed was reviewed for phase III randomized trials in patients with CRPC progressed after docetaxel chemotherapy. Characteristics of each study and the relative hazard ratio (HR) for overall survival and 95% confidence interval (CI) were collected...

The landscape of prostate cancer treatment is rapidly changing as extensive research into potential therapies yields new options. In this article, the literature is reviewed to identify emerging therapies for advanced prostate cancer. Emphasis is placed on agents that have been approved in the United States of America (USA) and the European Union, or that have reached phase III clinical studies. Several new therapies have been approved in recent years across different stages of the natural history of the disease...

In Europe, prostate cancer is the most common cancer among men with 382.000 new cases and 89.000 deaths annually. Historically, androgen deprivation therapy and docetaxel based chemotherapy were the only treatments able to improve survival. Two studies have been published during last few months regarding the management of castration resistant prostate cancer (CRPC) progressed after docetaxel: for the first time second line therapies have been demonstrated to improve prognosis of these patients. The relevance of these trials is the reintroduction of chemotherapy and hormonal therapy in a disease once considered chemotherapy and castration resistant...

If androgen deprivation, chemical with LH-RH analogs or surgical with bilateral orchiectomy, still remains the stone edge of treatment of prostate cancer, in the metastatic setting, this hormonosensitivity, most of the time long, finally move on in hormonal-failure. If rare changes in the therapeutic strategy have been achieved in this setting since 2004 and the arrival of docetaxel, it is the global perception of the disease that has been modified and the definition of one specific entity: the castrate-resistant prostate cancer...

Docetaxel is a reference treatment of metastatic prostate cancer castration-resistant. Until now, the different associations were studied without benefit when compared to docetaxel as monotherapy. Cabazitaxel showed efficacy in second-line in patients with progressive disease during or after docetaxel chemotherapy. Other molecules are being evaluated in second-line post-docetaxel. Abiraterone acetate is an alternative treatment to cabazitaxel in metastatic second-line resistant to castration. Predictive factors to choice treatment must be evaluated and proposed to personalize treatment in the future...

Prostate cancer is the most common noncutaneous cancer and the second leading cause of death from cancer in men in most western countries. Advanced prostate cancer is typically sensitive to androgen-deprivation therapy, but invariably progresses to the castration-resistant state. Most current prostate cancer treatments are based on cytotoxicity directed against tumor cells via androgen-deprivation therapy or chemotherapy. Chemotherapy with docetaxel represents the standard first-line treatment in patients with castration-resistant prostate cancer (CRPC)...

Treatment of metastatic castrate resistant prostate cancer (mCRPC) after progression on docetaxel chemotherapy is a challenging clinical scenario with limited availability of treatment options. Re-treatment with docetaxel, either as monotherapy or in combination with other cytotoxics or targeted agents has shown durable responses. However, most docetaxel re-treatment studies have been either retrospective or early phase non-randomised studies which have not formally assessed Quality of life or survival gain with re-treatment...

BACKGROUND: Based on the TAX 327 phase III trial, docetaxel-based chemotherapy is the standard first-line treatment for hormone-resistant prostate cancer (HRPC); however, there is some heterogeneity in the use of this agent in routine clinical practice. The aim of the present study was to examine the patterns of docetaxel use in routine clinical practice at our institution and to compare them with docetaxel use in the TAX 327 clinical trial. METHODS: We conducted a retrospective chart review of HRPC patients treated with first-line docetaxel between 2005 and 2007 at the Princess Margaret Hospital...

BACKGROUND: No standard therapy exists for post-docetaxel castrate-resistant prostate cancer (CRPC) patients. This trial aimed to determine the safety and efficacy of pemetrexed in post-docetaxel CRPC patients. MATERIALS AND METHODS: CRPC patients with progression after docetaxel (Taxotere) therapy received pemetrexed (500 mg/m2) i.v. every 3 weeks. The primary end point was prostate-specific antigen (PSA) response. A pharmacogenetic analysis of the reduced folate carrier-1 gene (RFC1) G80A polymorphism was also carried out...
