BACKGROUND: Docetaxel and cabazitaxel improve overall survival compared with mitoxantrone in patients with metastatic castration-resistant prostate cancer. Custirsen (OGX011) is a second generation highly specific antisense oligonucleotide that inhibits the production of clusterin, an antiapoptotic protein that is upregulated in response to chemotherapy and that confers treatment resistance. We aimed to assess whether custirsen in combination with cabazitaxel and prednisone increases overall survival in patients with metastatic castration-resistant prostate cancer previously treated with docetaxel...

Health-related quality of life (HRQoL) deteriorates rapidly in patients with advanced-stage cancer, with patients seriously disturbed by fatigue, sleep disorders, bone pain, constipation and other disease related symptoms. As treatment and prognosis continues to improve, reducing symptoms and improving quality of life with minimum of toxicities have become important therapeutic goals. The effectiveness of abiraterone acetate and enzalutamide in both prolonging life and improving quality of life in asymptomatic or mildly symptomatic patients with metastatic castrations-resistant prostate cancer (mCRPC) has been clinically proven...

AIMS: Treatments and disease burden of metastatic castration-resistant prostate cancer (mCRPC) considerably affect a patient's quality of life. However, patient-reported symptom burden data are still largely insufficient. This study sought to compare the self-reported symptom burden of men with chemotherapy-naive (CN) mCRPC treated with abiraterone acetate (AA) or enzalutamide (EZ) in routine clinical practice. MATERIALS AND METHODS: Between 2011 and 2015, 189 CN-mCRPC patients who had received AA (n = 76) or EZ (n = 113) at the Princess Margaret Cancer Centre were included...

Prostate cancer claims the lives of more than 25,000 men in the United States yearly, most from metastatic disease. In the past decade, several new medications have been approved for the treatment of metastatic prostate cancer including the antiandrogen enzalutamide. In addition, there has been mounting interest in evaluating health-related quality of life (QoL) in patients with cancer including new more detailed recommendations released by the Prostate Cancer Working Group 3 on how to evaluate patient-related outcomes in clinical trials...

Radioligand therapy (RLT) directed against prostate-specific membrane antigen (PSMA) enables tumor-specific treatment directed against PSMA-overexpressing prostate cancer cells. Several PSMA ligands such as PSMA-617 or PSMA-I&T have been developed that can be labeled with β‑radiating lutetium-177. These are currently applied in compassionate use programs to treat metastatic castration-resistant prostate cancer (mCRPC). PSMA-directed RLT is currently being offered in several nuclear medicine departments throughout Germany...

Cabazitaxelis a taxane-type antineoplastic agent used for treating prostate cancer. Although typical side effects include neutropenia and fatigue, no studies have investigated eye disorders as a possible side effect, and the details are not clear. Herein, we report our experience of an undeniable case of optic neuropathy caused by cabazitaxel. A 78-year-old man had been diagnosed with prostate cancer (cT3aN1M1b, stage IV) 3 years previously, with a treatment history of bicalutamide, leuprorelin, flutamide, docetaxel, abiraterone, and enzalutamide...

Enzalutamide is a novel, non-steroidal anti-androgen that was approved for the treatment of patients with castration-resistant prostate cancer (CRPC) in 2014 in Japan. To assess the potency of enzalutamide treatment in Japan, we performed a pilot retrospective study. Among 91 patients who received treatment in our Institution between May 2014 and July 2015, 51 patients with docetaxel-naïve CRPC (56.0%) underwent enzalutamide therapy. The median progression-free survival (PFS) and overall survival (OS) were 10...

BACKGROUND: Prostate cancer is a heterogeneous disease, but current treatments are not based on molecular stratification. We hypothesized that metastatic, castration-resistant prostate cancers with DNA-repair defects would respond to poly(adenosine diphosphate [ADP]-ribose) polymerase (PARP) inhibition with olaparib. METHODS: We conducted a phase 2 trial in which patients with metastatic, castration-resistant prostate cancer were treated with olaparib tablets at a dose of 400 mg twice a day...

Three-weekly docetaxel plus prednisone is the standard first-line cytotoxic treatment for patients with metastatic castrate-resistant prostate cancer (mCRPC). Today, several new treatment options are available for patients with tumor progression after first-line docetaxel: Abiraterone, enzalutamide, cabazitaxel, sipuleucel-T immunotherapy, and the radionuclide radium-223. However, despite the evolving scenario in CRPC treatment, the optimal sequencing of the innovative therapies remains unclear. The reintroduction of docetaxel at the occurrence of disease progression after a drug holiday (docetaxel rechallenge) was often proposed, and this chemotherapeutic agent showed to maintain antitumor activity in mCRPC patients...
