Prostate tumors are among the most heterogeneous of cancers, both histologically and clinically. Microarray expression analysis was used to determine whether global biological differences underlie common pathological features of prostate cancer and to identify genes that might anticipate the clinical behavior of this disease. While no expression correlates(More)
CONTEXT Survival benefit in the management of high-grade clinically localized prostate cancer has been shown for 70 Gy radiation therapy combined with 3 years of androgen suppression therapy (AST), but long-term AST is associated with many adverse events. OBJECTIVE To assess the survival benefit of 3-dimensional conformal radiation therapy (3D-CRT) alone(More)
The human DAZ gene family is expressed in germ cells and consists of a cluster of nearly identical DAZ (deleted in azoospermia) genes on the Y chromosome and an autosomal homolog, DAZL (DAZ-like). Only the autosomal gene is found in mice. Y-chromosome deletions that encompass the DAZ genes are a common cause of spermatogenic failure in men, and autosomal(More)
PURPOSE To present nomograms providing estimates of prostate-specific antigen (PSA) failure-free survival after radical prostatectomy (RP) or external-beam radiation therapy (RT) for men diagnosed during the PSA era with clinically localized disease. PATIENTS AND METHODS A Cox regression multivariable analysis was used to determine the prognostic(More)
CONTEXT Comorbidities may increase the negative effects of specific anticancer treatments such as androgen suppression therapy (AST). OBJECTIVES To compare 6 months of AST and radiation therapy (RT) to RT alone and to assess the interaction between level of comorbidity and all-cause mortality. DESIGN, SETTING, AND PATIENTS At academic and(More)
PURPOSE Identifying pretreatment and posttreatment predictors of time to prostate cancer-specific death (PCSD) after external-beam radiation therapy (RT) was the subject of this study. PATIENTS AND METHODS A Cox regression analysis was used to evaluate the ability of the pretreatment risk group to predict time to PCSD for 381 patients who underwent RT for(More)
The majority of renal neoplasms can be distinguished on the basis of histologic examination alone; however, there are morphologic similarities between clear cell renal carcinoma and chromophobe cell carcinoma, as well as between the granular/eosinophilic variants of these tumors and renal oncocytoma. Only a limited number of histochemical markers are(More)
PURPOSE To identify events that precipitated a prostate-specific antigen (PSA) bounce and characterize the magnitude, duration, and time to PSA bounce after MRI-guided prostate brachytherapy. METHODS AND MATERIALS Between 1997 and 2001, 186 patients with low-risk prostate cancer underwent MRI-guided permanent 125I source implantation, with or without(More)
BACKGROUND To the authors' knowledge, consensus is lacking regarding the relative long-term efficacy of radical prostatectomy (RP) versus conventional-dose external beam radiation therapy (RT) in the treatment of patients with clinically localized prostate carcinoma. METHODS A retrospective cohort study of 2635 men treated with RP (n = 2254) or(More)
The epidermal growth factor receptor (HER1) has been implicated in regenerative growth and proliferative diseases of the human bladder epithelium (urothelium), however a cognate HER1 ligand that can act as a growth factor for normal human urothelial cells (HUC) has not been identified. Here we show that heparin-binding EGF-like growth factor (HB-EGF), an(More)
