Complete and rogen blockade has a small survival benefit of about 5 % .
Intermittent and rogen deprivation ( IAD ) results in equivalent oncologic efficacy when compared with continuous and rogen-deprivation therapy ( ADT ) in well-selected population s. In locally advanced and metastatic PCa , early ADT does not result in a significant survival advantage when compared with delayed ADT .
Zoledronic acid and denusomab can be used in men with CRPC and osseous metastases to prevent skeletal-related complications .
OBJECTIVES Our aim is to present a summary of the 2010 version of the European Association of Urology ( EAU ) guidelines on the treatment of advanced , relapsing , and castration-resistant prostate cancer ( CRPC ) .
The guidelines were up date d , and the levels of evidence ( LEs ) and /or grade s of recommendation ( GR ) were added to the text based on a systematic review of the literature , which included a search of online data bases and bibliographic review s. RESULTS Luteinising hormone-releasing hormone ( LHRH ) agonists are the st and ard of care in metastatic prostate cancer ( PCa ) .
Although LHRH antagonists decrease testosterone without any testosterone surge , their clinical benefit remains to be determined .
Treatment of castration-resistant prostate cancer ( CRPC ) includes second-line hormonal therapy , novel agents , and chemotherapy with docetaxel at 75 mg/m(2 ) every 3 wk .
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
