Castration resistance prostate cancer. what is in the pipeline?

INTRODUCTION: To evaluate the available evidence on the standard diagnosis and management of men with metastatic castration resistant prostate cancer (mCRPC), and providing the timely update on new pharmacological treatments. EVIDENCEACQUISITION: Asystematic literature search from from January 2000 until March 2017 was performed by combining the following MESH terms: castrate resistant prostate cancer, abiraterone, enzalutamide, 223radium, sipuleucel-T, docetaxel, cabazitaxel, resistance mechanisms, resistance to androgen deprivation, androgen receptor (AR) mutations, amplifications, splice variants, and AR alterations. We followed the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA). EVIDENCESYNTHESIS: In the few last years the introduction of new treatment modalities as abiraterone or enzalutamide have significantly change our prospective in mCRPC management increasing patients survival and quality of life. The standard imaging modalities to define the presence of regional or distant metastasis or the different resistant mechanisms to the available treatments are still an issue of debate, however several studies are ongoing to define the standard of care and to reduce treatments' resistance. Data from ongoing phase IIItrials are awaited to introduce in clinical new effective treatments that can be used in patients resistant to abiraterone/enzalutamide or more probably in a different phase of the disease. CONCLUSIONS: Castration resistant prostate cancer is now the key issue in prostate cancer management and research. Our challenge in the near future will be to identify the right treatment or better the right combination and sequencing of treatments that should be used in patients with mCRPCor even with advanced prostate cancer.
