OBJECTIVE: To determine if tumor cell density and percentage of Gleason pattern within an outlined volumetric tumor region of interest (TROI) on whole-mount pathology (WMP) correlate with apparent diffusion coefficient (ADC) values on corresponding TROIs outlined on pre-operative MRI. METHODS: Men with biopsy-proven prostate adenocarcinoma undergoing multiparametric MRI (mpMRI) prior to prostatectomy were consented to this prospective study. WMP and mpMRI images were viewed using 3D Slicer and each TROI from WMP was contoured on the high b-value ADC maps (b0, 1400)...

As the First-In-Human study of in situ gene therapy using an adenovirus vector carrying the human REIC (reduced expression in immortalized cell)/Dkk-3 gene (Ad-REIC), we conducted neoadjuvant intraprostatic injections in patients with high-risk localized prostate cancer undergoing radical prostatectomy (RP). Patients with recurrence probability of 35% or more within 5 years following RP, as calculated by Kattan's nomogram, were enrolled. Patients received two ultrasound-guided intratumoral injections at 2-week intervals, followed by RP 6 weeks after the second injection...

INTRODUCTION AND OBJECTIVES: Prostate cancer (PCa) represents an important target for chemoprevention given its prolonged natural history and high prevalence. Epidemiologic and laboratory data suggest that vitamin D and genistein (soy isoflavone) may decrease PCa progression. The effect of vitamin D on prostate epithelial cell proliferation and differentiation is well documented and genistein may augment this affect through inhibition of the CYP24 enzyme, which is responsible for intracellular vitamin D metabolism...

OBJECTIVE: To assess the patient's perceived causes of PCa and relation to treatment satisfaction an internet based survey study was designed. Prostate cancer (PCa) is a profoundly personal disease considering the location and common sequelae of treatment. Deeply held patient self-perceptions regarding the etiology of a patient's PCa may generate lasting beliefs that impact satisfaction with treatment selection. METHODS: Third-party web-based surveys were sent to patients receiving radical prostatectomy for clinically localized PCa...

Prostate Cancer represents the second leading cause of cancer death among men in the United States, and the third leading cause of cancer death among men in Europe. We have previously shown that cells possessing Cancer Stem Cell (CSC) characteristics can be grown from human PrCa tissue harvested at the time of prostatectomy. However, the cellular origin of these CSCs was not previously known. In most cases, simple hematoxylin and eosin (H&E) stained sections are sufficient to make a definitive diagnosis of prostatic adenocarcinoma (PrCa) in needle biopsy samples...

Lower urinary tract outflow dysfunction is frequent in older men and a potential cause of serious complications such as acute urinary retention (AUR). Drug-induced AUR has only rarely been reported with selective serotonin reuptake inhibitors including escitalopram; reported cases had no history of urinary outflow dysfunction. We herein report the development of AUR after the introduction of escitalopram at a standard dose in 3 male patients with previously diagnosed or unknown/latent and nonsymptomatic benign prostatic hyperplasia...

Focal therapy (FT) represents a potential shift in clinical practice by featuring a tissue-sparing approach for prostate cancer (PCa) treatment. It stands midway between active surveillance (AS) and more aggressive options like radical prostatectomy (RP) or radiotherapy. The field has enormously evolved in the last few years but there are still pending questions to answer in the future. The manuscript overlooks FT in terms of indications, available energies, situation of tumor microenvironment, follow-up, re-interventions, and the future of this approach for PCa...

INTRODUCTION: With healthcare reform, cost and patient satisfaction will directly affect hospital reimbursement. We present data on same day discharge (SDD) for patients who underwent robot assisted laparoscopic radical prostatectomy (RALP). METHODS: Patient data were gathered in an IRB approved database. In April 2015, surgeon (SJ) began SDD. The SDD protocol for RALP includes multimodal anesthesia/analgesia and extended recovery. Interim analysis revealed that government insurance (CMS) refused hospital reimbursement for SDD...

PURPOSE: Degarelix, a new GnRH receptor antagonist with demonstrated efficacy as first-line treatment in the management of high-risk prostate cancer, possesses some theoretical advantages over LHRH analogues in terms of avoiding "testosterone flare" and lower FSH levels. We set out to determine if pre-operative degarelix influenced surrogates of disease control in a randomized phase II study. EXPERIMENTAL DESIGN: 39 patients were randomly assigned to one of 3 different neo-adjuvant arms: degarelix only, degarelix/bicalutmaide, or LHRH agonist/bicalutamide...

INTRODUCTION: The literature is conflicting on the long-term utility of adjuvant therapy after radical prostatectomy (RP) for prostate cancer (PCa) demonstrating seminal vesicle invasion (pT3b; SVI). METHODS: Patients with SVI during RP and pelvic lymph node dissection at two major referral centers from 1986-2014 were included. Kaplan-Meier analyses and multivariable Cox regressions were performed to determine if adjuvant radiotherapy (aRT) and adjuvant hormonal therapy (aHT) were predictors of biochemical recurrence, cancer specific mortality (CSM) and overall mortality (OM)...

BACKGROUND: Calcium channel blockers (CCBs) may affect prostate cancer (PCa) growth by various mechanisms including those related to androgens. The fusion of the androgen-regulated gene TMPRSS2 and the oncogene ERG (TMPRSS2:ERG or T2E) is common in PCa, and prostate tumors that harbor the gene fusion are believed to represent a distinct disease subtype. We studied the association of CCB use with the risk of PCa, and molecular subtypes of PCa defined by T2E status. METHODS: Participants were residents of King County, Washington, recruited for population-based case-control studies (1993-1996 or 2002-2005)...

BACKGROUND: A new prostate cancer (PCa) grading system (namely, Gleason score-GS- ≤6 vs. 3 + 4 vs. 4 + 3 vs. 8 vs. ≥9) was recently proposed and assessed on biochemical recurrence (BCR) showing improved predictive abilities compared to the commonly used three-tier system (GS ≤6 vs. 7 vs. ≥8). We assessed the predictive ability of the five-tier grade group (GG) system on harder clinical endpoint, namely clinical recurrence (CR). METHODS: Between 2005 and 2014, 9,728 clinically localized PCa patients were treated with radical prostatectomy (RP) at two tertiary referral centers...

The present study investigated the association between radical prostatectomy (RP) and the risk of herpes zoster (HZ). Male patients aged ≥ 40 years and diagnosed with prostate cancer (PCa) between 2000 and 2005 were included in this study. Patients who underwent RP for the first time during 2000-2006 were included in the RP group. Randomly selected individuals from among the remaining patients with PCa who did not undergo RP were included in the non-RP group. Univariate and multivariate Cox regression models were used to analyze the association between PCa and HZ...

BACKGROUND: One of the key factors contributing to morbidity associated with salvage radical prostatectomy is a significant vesicourethral anastomosis (VUA) disruption or postoperative tissue dehiscence in the region of the distal bladder neck that causes a large prolonged urinary leak, perineal pain, and delayed catheter removal. OBJECTIVE: To describe our surgical technique using a urinary bladder extracellular matrix (UB-ECM) scaffold incorporated into the base of the VUA and the distal bladder neck during salvage robot-assisted radical prostatectomy (sRARP) and to assess outcomes and safety...

To evaluate the role of multiparametric magnetic resonance imaging (mpMRI) in predicting upgrading, upstaging, and extraprostatic extension in patients with low-risk prostate cancer (PCa). MpMRI may reduce positive surgical margins (PSM) and improve nerve-sparing during robotic-assisted radical prostatectomy (RARP) for localized prostate cancer PCa.This was a retrospective, monocentric, observational study. We retrieved the records of patients undergoing RARP from January 2012 to December 2013 at our Institution...
