PURPOSE Aberrant activation of the Wingless-type (Wnt) pathway plays a significant role in the pathogenesis of several human cancers. Wnt inhibitory factor-1 (Wif-1) was identified as one of the secreted antagonists that can bind Wnt protein. We hypothesize that Wif-1 plays an important role in bladder cancer pathogenesis. EXPERIMENTAL DESIGN To test this(More)
OBJECTIVES Controversy exists regarding the benefit of extended lymphadenectomy at radical prostatectomy for prostate cancer. We sought to determine whether more extended lymphadenectomy, along with radical prostatectomy, resulted in a decreased risk of prostate cancer-specific death at 10 years. METHODS Data on all patients undergoing radical(More)
BACKGROUND Active surveillance followed by selective treatment for men who have evidence of disease progression may be an option for select patients with early-stage prostate cancer. In this article, the authors report their experience in a contemporary cohort of men with prostate cancer who were managed with active surveillance. METHODS All men who were(More)
OBJECTIVES This study was designed to determine whether citrate levels detected by localized 1H spectroscopy could reliably discriminate regions of prostate adenocarcinoma from surrounding regions of normal peripheral zone and benign prostatic hyperplasia (BPH). METHODS In 28 patients and 5 volunteers stimulated echo proton spectroscopy was used in(More)
Risk for prostate cancer is high among African Americans. We hypothesized that risk for prostate cancer is also high in other populations of African descent. Our objective was to determine the screening-detected prevalence of prostate cancer in the predominantly Afro-Caribbean population on the island of Tobago. Male residents, ages 40-79 years, were(More)
PURPOSE The guideline purpose is to provide the urologist with a framework for the early detection of prostate cancer in asymptomatic average risk men. MATERIALS AND METHODS A systematic review was conducted and summarized evidence derived from over 300 studies that addressed the predefined outcomes of interest (prostate cancer incidence/mortality,(More)
PURPOSE The benefit of pelvic lymphadenectomy in patients with bladder cancer remains controversial. We analyzed the impact of lymphadenectomy on disease specific survival in a population based sample of patients with bladder cancer who underwent radical cystectomy. MATERIALS AND METHODS Analysis included data on 1,923 patients who underwent radical(More)
OBJECTIVES To determine the morbidity and mortality from radical cystectomy in a nationally representative population-derived sample. Complications after radical cystectomy have been reported from large single-institution series but population-based representative data are lacking. METHODS All patients undergoing radical cystectomy for bladder cancer were(More)
CONTEXT Our aim was to present a summary of the Second International Consultation on Bladder Cancer recommendations on the diagnosis and treatment options for non-muscle-invasive urothelial cancer of the bladder (NMIBC) using an evidence-based approach. OBJECTIVE To critically review the recent data on the management of NMIBC to arrive at a general(More)
OBJECTIVES Risk factors for prostate cancer (PCa)-related mortality include old age, black race, and residence in northern latitudes. The objectives of this study are to examine the in vitro and in vivo effects of 1,25-dihydroxycholecalciferol (1,25-D3) and less-hypercalcemic analogues on the Dunning rat prostate adenocarcinoma model. METHODS To evaluate(More)
