BACKGROUND: Variation in PSA screening is a potential source of disparity in prostate cancer survival, particularly among underserved populations. We sought to examine the impact of race and socioeconomic status (SES) on receipt of PSA testing among low-income men. METHODS: Black (n=22 167) and White (n=9588) men aged ⩾40 years completed a baseline questionnaire from 2002 to 2009 as part of the Southern Community Cohort Study. Men reported whether they had ever received PSA testing and had testing within the prior 12 months...

BACKGROUND: Obesity, a cause of subclinical inflammation, is associated with increased risk of high-grade prostate cancer (PC) and poor outcomes. Whether inflammation occurs in periprostatic white adipose tissue (WAT), and contributes to the negative impact of obesity on PC aggressiveness, is unknown. METHODS: In a single-center, cross-sectional design, men with newly diagnosed PC undergoing radical prostatectomy were eligible for study participation. The primary objective was to examine the prevalence of periprostatic WAT inflammation defined by the presence of crown-like structures (CLS-P) as detected by CD68 immunohistochemistry...

BACKGROUND: Surgery and radiation-based therapies are standard management options for men with clinically localized high-risk prostate cancer (PCa). Contemporary patterns of care are unknown. We hypothesize the use of surgery has steadily increased in more recent years. METHODS: Using the National Cancer Data Base for 2004-2013, all men diagnosed with high-risk localized PCa were identified using National Comprehensive Cancer Network criteria. Temporal trends in initial management were assessed...

BACKGROUND: Radical prostatectomy is a common surgical procedure performed to treat prostate cancer. Patient-reported outcomes after surgery include urinary incontinence, erectile dysfunction, decreased quality of life and psychological effects. Predictive tools to assess the likelihood of an individual experiencing various patient-reported outcomes have been developed to aid decision-making when selecting treatment. METHODS: A systematic review was undertaken to identify all papers describing tools for the prediction of patient-reported outcome measures in men with prostate cancer treated with radical prostatectomy...

BACKGROUND: To evaluate whether the presence of both prostate atrophy (PA) and chronic prostate inflammation (CPI) in the same biopsy and in the same biopsy core are associated with prostate cancer (PCa) risk and grade in repeat biopsies. METHODS: Retrospective analyses of 6132 men who were 50-75 years old undergoing 2-year repeat prostate biopsy after a negative baseline biopsy for PCa in the REduction by DUtasteride of prostate Cancer Events (REDUCE) study. PA, CPI and PCa were determined by central pathology...

BACKGROUND: Despite high rates of disease misclassification and sepsis, the use of transrectal biopsy remains commonplace. Transperineal mapping biopsies mitigate these problems but carry increased cost and patient burden. Local anaesthetic, multiparametric magnetic resonance imaging (MRI)-targeted transperineal biopsy may offer an alternative. Here, we aim to determine the feasibility, tolerability and detection rates of clinically significant prostate cancer using a local anaesthetic, transperineal, MRI-targeted biopsy technique...

BACKGROUND: Several randomized controlled trials assessed the outcomes of patients treated with neoadjuvant hormonal therapy (NHT) before radical prostatectomy (RP). The majority of them included mainly low and intermediate risk prostate cancer (PCa) without specifically assessing PCa-related death (PCRD). Thus, there is a lack of knowledge regarding a possible effect of NHT on PCRD in the high-risk PCa population. We aimed to analyze the effect of NHT on PCRD in a multicenter high-risk PCa population treated with RP, using a propensity-score adjustment...

BACKGROUND: Which men benefit most from adding androgen deprivation therapy (ADT) to salvage radiation therapy (SRT) after prostatectomy has not clearly been defined; therefore, we evaluated the impact of ADT to SRT on failure-free survival (FFS) in men with a rising or persistent PSA after prostatectomy. METHODS: We identified 332 men who received SRT after prostatectomy from 1987 to 2010. Recursive partitioning analysis (RPA) identified favorable, intermediate and unfavorable groups based on the risk of failure after SRT alone...

BACKGROUND: To ascertain 3-year urinary continence (UC) and sexual function (SF) recovery following robot-assisted radical prostatectomy (RARP) for clinically high-risk prostate cancer (PCa). METHODS: Retrospective analyses of a prospectively maintained database for 769 patients with D'Amico high-risk PCa undergoing RARP at two tertiary care centers in the United States and Europe between 2001 and 2014. The association between time since RARP and recovery of UC (defined as 0 pad/one safety liner per day) and SF (defined as sexual health inventory for men (SHIM) score ⩾17) was tested in separate preoperative and post-operative Cox-proportional hazards regression models...

BACKGROUND: Analysis of systematic 12-core biopsies (SBx) has shown that African-American (AA) men tend to harbor higher risk prostate cancer (PCa) at presentation relative to other races. Multiparametric magnetic resonance imaging (mpMRI) and MRI-ultrasound fusion-guided biopsy (FBx) have been shown to diagnose more intermediate- and high-risk PCa in the general population; however, the efficacy in AA remains largely uncharacterized. We aim to evaluate the utility of FBx in an AA patient cohort...

BACKGROUND: Promising therapeutic results of the prostate-specific membrane antigen (PSMA) ligand have been shown when labelling with lutetium-177 ((177)Lu). We performed a systematic review and meta-analysis to assess the therapeutic response of (177)Lu-PSMA in the treatment of metastatic castration-resistant prostate cancer (mCRPC). METHODS: A systematic review was conducted using electronic databases up to December 2016. Two reviewers independently extracted data and assessed methodological quality...

BACKGROUND: Prostate cancer (PCa) is the fifth leading cause of cancer-related deaths worldwide. Many epidemiological studies have investigated the association between prostate cancer and lycopene, however, results have been inconsistent. This study aims to determine the impact of dietary and circulating concentrations of lycopene on PCa risk and to investigate potential dose-response associations. METHODS: We conducted a systematic review and dose-response meta-analysis for the for the association between dietary and circulating lycopene and PCa risk...

BACKGROUND: Active surveillance (AS) has excellent short to medium term outcomes in well-selected prostate cancer patients. Traditional biopsy-based selection criteria have been criticized for inaccurate determination of cancer grade and extent. We evaluated the incremental benefit of multiparametric magnetic resonance imaging (mpMRI) in patient selection using various AS criteria. METHODS: We retrospectively evaluated men who received mpMRI before radical prostatectomy between 2011 and 2014...

BACKGROUND: While older age is associated with higher tumor grade, it is unknown whether comorbid disease burden has a similar, independent association. We sought to evaluate the impact of comorbid disease burden on tumor grade at diagnosis as indicated by biopsy Gleason score. METHODS: We conducted an observational cohort study of 1260 men newly diagnosed with non-metastatic prostate cancer from 1998 to 2004 at two Veterans Affairs Medical Centers. Multivariable ordinal and multinomial logistic regression were used to evaluate the association between Charlson Comorbidity Index score and biopsy Gleason score...

M I Gökce, D Sundi, E Schaeffer, C Pettaway
BACKGROUND: Certain patients presenting with either low or very-low-risk prostate cancer (PCa) can represent a therapeutic dilemma for physicians. The oncologic outcomes of active surveillance (AS) for men with very-low-risk PCa are overall excellent. However, there are concerns about AS related to the potential for upgrading or upstaging. The African American (AA) population is under-represented in studies evaluating AS outcomes and this is particularly important because of the unique epidemiology of PCa in AA men...

BACKGROUND: Previously, we showed that carbohydrate restriction with calorie restriction slowed tumor growth in xenograft mouse prostate cancer models. Herein, we examined the impact of carbohydrate restriction without calorie restriction on tumor development within the context of diet-induced obesity in the Hi-Myc transgenic mouse model of prostate cancer. METHODS: Mice were randomized at 5 weeks of age to ad libitum western diet (WD; 40% fat, 42% carbohydrate; n=39) or ad libitum no carbohydrate ketogenic diet (NCKD; 82% fat, 1% carbohydrate; n=44)...
