Zoledronic acid and denosumab can be used in men with mCRPC and osseous metastases to prevent skeletal-related complications .
PATIENT SUMMARY In men with a rise in their PSA levels after prior local treatment for prostate cancer only , it is important to balance overtreatment against further progression of the disease since survival and quality of life may never be affected in many of these patients .
OBJECTIVE To present a summary of the 2016 version of the European Association of Urology ( EAU ) - European Society for Radiotherapy & Oncology ( ESTRO ) - International Society of Geriatric Oncology ( SIOG ) Guidelines on the treatment of relapsing , metastatic , and castration-resistant prostate cancer ( CRPC ) .
EVIDENCE SYNTHESIS Relapse after local therapy is defined by a rising prostate-specific antigen ( PSA ) level > 0.2ng/ml following radical prostatectomy ( RP ) and > 2ng/ml above the nadir after radiation therapy ( RT ) .
And rogen deprivation therapy ( ADT ) remains the basis for treatment of men with metastatic prostate cancer ( PCa ) .
Level 1 evidence for the treatment of metastatic CRPC ( mCRPC ) includes , abiraterone acetate plus prednisone ( AA/P ) , enzalutamide , radium 223 ( Ra 223 ) , docetaxel at 75 mg/m2 every 3 wk and sipuleucel-T. Cabazitaxel , AA/P , enzalutamide , and radium are approved for second-line treatment of CRPC following docetaxel .
CONCLUSIONS The knowledge in the field of advanced and metastatic PCa and CRPC is changing rapidly .
Design and end points of clinical trials for patients with progressive prostate cancer and castrate levels of testosterone: recommendations of the Prostate Cancer Clinical Trials Working Group.
PURPOSE To up date eligibility and outcome measures in trials that evaluate systemic treatment for patients with progressive prostate cancer and castrate levels of testosterone . METHODS A committee of investigators experienced in conducting trials for prostate cancer defined new consensus criteria by review ing previous criteria , Response Evaluation Criteria in Solid Tumors ( RECIST ) , and emerging trial data . RESULTS The Prostate Cancer Clinical Trials Working Group ( PCWG2 ) recommends a two- objective paradigm : ( 1 ) controlling , relieving , or eliminating disease manifestations that are present when treatment is initiated and ( 2 ) preventing or delaying disease manifestations expected to occur . Prostate cancers progressing despite castrate levels of testosterone are considered castration resistant and not hormone refractory . Eligibility is defined using st and ard disease assessment s to authenticate disease progression , prior treatment , distinct clinical subtypes , and predictive models . Outcomes are reported independently for prostate-specific antigen ( PSA ) , imaging , and clinical measures , avoiding grouped categorizations such as complete or partial response . In most trials , early changes in PSA and /or pain are not acted on without other evidence of disease progression , and treatment should be continued for at least 12 weeks to ensure adequate drug exposure . Bone scans are reported as " new lesions " or " no new lesions , " changes in soft-tissue disease assessed by RECIST , and pain using vali date d scales . Defining eligibility for prevent/delay end points requires attention to estimated event frequency and /or r and om assignment to a control group . CONCLUSION PCWG2 recommends increasing emphasis on time-to-event end points ( ie , failure to progress ) as decision aids in proceeding from phase II to phase III trials . Recommendations will evolve as data are generated on the utility of intermediate end points to predict clinical benefit
