The prostate-specific antigen test has been a major factor in increasing awareness and better patient management of prostate cancer (PCA), but its lack of specificity limits its use in diagnosis and makes for poor early detection of PCA. The objective of our studies is to identify better biomarkers for early detection of PCA using protein profiling(More)
BACKGROUND Intermittent androgen deprivation for prostate-specific antigen (PSA) elevation after radiotherapy may improve quality of life and delay hormone resistance. We assessed overall survival with intermittent versus continuous androgen deprivation in a noninferiority randomized trial. METHODS We enrolled patients with a PSA level greater than 3 ng(More)
BACKGROUND Sipuleucel-T is an investigational active cellular immunotherapy product designed to stimulate an immune response against prostate cancer. The safety and efficacy of sipuleucel-T was evaluated in 2 identically designed, randomized, double-blind, placebo-controlled trials (D9901 and D9902A) conducted in men with advanced prostate cancer. METHODS(More)
In 1996 the American Society for Therapeutic Radiology and Oncology (ASTRO) sponsored a Consensus Conference to establish a definition of biochemical failure after external beam radiotherapy (EBRT). The ASTRO definition defined prostate specific antigen (PSA) failure as occurring after three consecutive PSA rises after a nadir with the date of failure as(More)
PURPOSE Sipuleucel-T (APC8015) is an investigational immunotherapy product designed to stimulate T-cell immunity against prostatic acid phosphatase. A phase III study was undertaken to evaluate the safety and efficacy of sipuleucel-T in a placebo-controlled study. PATIENTS AND METHODS A total of 127 patients with asymptomatic metastatic hormone refractory(More)
BACKGROUND Few data exist regarding the impact on survival of definitive treatment of the prostate in men diagnosed with metastatic prostate cancer (mPCa). OBJECTIVE To evaluate the survival of men diagnosed with mPCa based on definitive treatment of the prostate. DESIGN, SETTING, AND PARTICIPANTS Men with documented stage IV (M1a-c) PCa at diagnosis(More)
OBJECTIVE We investigated the disease-specific and metastasis-free survival rates in men with locally advanced (clinical stage T3) prostate cancer who were treated surgically. METHODS A retrospective, multi-institutional pooled analysis of the results of surgical treatment in 345 men with clinical stage T3 disease was performed. Survival curves were(More)
PURPOSE To develop evidence-based guidelines for (1) prostate re-biopsy after radiation and (2) radiation therapy with rising prostate-specific antigen (PSA) levels after radical prostatectomy in the management of patients with localized prostatic cancer. DESIGN The American Society of Therapeutic Radiology and Oncology (ASTRO) challenged a(More)
OBJECTIVE To explore the prognostic and predictive value of baseline variables in 512 patients with metastatic castration-resistant prostate cancer from the phase III Immunotherapy for Prostate Adenocarcinoma Treatment (IMPACT) trial who were randomized to receive sipuleucel-T or control. METHODS The most powerful of these prognostic factors, baseline(More)
