BACKGROUND: Several agents have demonstrated an overall survival (OS) benefit in patients with metastatic castration-resistant prostate cancer (mCRPC); however, the optimal sequencing of these therapies is unknown as a result of a lack of prospective randomized controlled trials. This retrospective study aimed to identify clinical factors influencing outcomes and to determine optimal treatment sequencing in patients with mCRPC treated with cabazitaxel (CABA) and/or androgen receptor-targeted agents (ART) after androgen-deprivation therapy (ADT) and docetaxel (DOC)...

BACKGROUND: Several systemic treatments have been shown to increase survival for patients with metastatic castration-resistant prostate cancer. This study sought to characterize variation in use of the six "focus drugs" (docetaxel, abiraterone, enzalutamide, sipuleucel-T, radium-223, and cabazitaxel) that have been approved by the Food and Drug Administration for the treatment of metastatic castration-resistant prostate cancer during the years 2010-2015. We hypothesized that the use of these treatments would vary over time and by region of the country...

Recent reports have emphasized the clinical relevance of detecting the androgen receptor splice variant 7 (AR-V7) in circulating tumor cells (CTCs). Our aim was to set up a validated multicenter pipeline to measure AR-V7 by RT-qPCR in RNA isolated from CellSearch-enriched CTCs to provide an AR-V7 positive/negative score in a clinically acceptable time range. CellSearch-enirched CTCs from metastatic castration-resistant prostate cancer patients were characterized by RT-qPCR. After optimization it was prospectively tested whether it was possible to report the AR-V7 status within 11 days (PRELUDE study)...

Cabazitaxel is a second-generation semisynthetic taxane. The recognized anti-neoplastic effect of Cabazitaxel is cell cycle perturbation by inducing arrest at G2/M. Since glioblastoma tumors have a relatively high expression of P-gp, it is encouraging to find a treatment that is effective against these tumors. This study was conducted to examine the radiosensitizing potential of Cabazitaxel against U87MG cells. In order to evaluate the effect of Cabazitaxel, cells were treated with different concentrations of the drug at different time intervals and then cytotoxicity and cell cycle were assessed using MTT and flow cytometry assays, respectively...

Castration-resistant prostate cancer is an incurable disease. To date, six agents-abiraterone, enzalutamide, docetaxel, cabazitaxel, radium-223 and sipuleucel-T- have shown clinical efficacy in phase III clinical trials, leading to their FDA approval. Patients are typically sequenced through most or all of these agents, and then eventually succumb to their disease. Development of new treatments remains an unmet need. We report a case of a patient who progressed on enzalutamide with a single enlarging metastatic lesion, was treated with ablative stereotactic body radiation therapy while maintaining the same systemic treatment, who then had durable complete remission...

BACKGROUND: Treatment options for metastatic castration-resistant prostate cancer (mCRPC) have expanded in recent years and include cytotoxic agents (e.g., docetaxel and cabazitaxel), immunotherapy (e.g., sipuleucel-T), oral hormonal therapies targeting the androgen receptor axis (e.g., enzalutamide and abiraterone), and targeted alpha therapy (e.g., radium-223 dichloride (radium-223)). Although treatment guidelines have been updated to reflect the availability of new agents, it is not easy to apply them in daily clinical practice because recommendations vary depending on patient comorbidities and disease characteristics...

Inactivation of the androgen receptor (AR) pathway by androgen deprivation therapy (ADT) is the mainstay of (metastatic) prostate cancer therapy. Ultimately, the AR pathway will be re-activated despite castrate levels of circulating androgens. Thereby, maintaining its role even in castration resistant prostate cancer (CRPC). The recent STAMPEDE and CHAARTED trials showed that docetaxel in combination with ADT increased survival in hormone sensitive prostate cancer patients, suggesting cross-talk between AR signaling and chemotherapy efficacy...
