BACKGROUND: It is well known that the gastrointestinal (GI) microbiota can influence the metabolism, pharmacokinetics, and toxicity of cancer therapies. Conversely, the effect of cancer treatments on the composition of the GI microbiota is poorly understood. We hypothesized that oral androgen receptor axis-targeted therapies (ATT), including bicalutamide, enzalutamide, and abiraterone acetate, may be associated with compositional differences in the GI microbiota. METHODS: We profiled the fecal microbiota in a cross-sectional study of 30 patients that included healthy male volunteers and men with different clinical states of prostate cancer (i...

BACKGROUND: Magnetic resonance imaging (MRI)/ultrasound (US) fusion-guided biopsy has improved the ability to localize and detect prostate cancer (PCa) with efficiency surpassing systematic biopsy. Nevertheless, some patients have PCa missed using the MRI-targeted biopsy sampling alone. We aim to identify clinical and imaging parameters associated with cases where targeted biopsy did not detect PCa compared to systematic biopsy. METHODS: We conducted a retrospective review of patients who underwent MRI/US fusion-guided biopsy in addition to concurrent systematic, extended-sextant biopsy between 2014 and 2017...

BACKGROUND: Patients with prostate cancer are at risk of impaired bone health. Prostate cancer has a propensity to metastasize to bone, after which patients are at risk of skeletal-related events (SREs). These complications are associated with increased mortality, substantial pain, and reduced quality of life. Patients are also at risk of bone loss due to androgen deprivation therapy (ADT), which can be compounded in elderly patients with reduced bone density. It is essential, therefore, that aspects of bone health and therapies able to prevent the occurrence of SREs are considered throughout the clinical course of prostate cancer...

BACKGROUND: Whether androgen deprivation therapy (ADT) causes excess thromboembolic events (TEs) in men with prostate cancer (PCa) remains controversial and is the subject of the US Food and Drug Administration safety warning. This study aims to perform a systematic review and meta-analysis on previous studies to determine whether ADT is associated with TEs in men with PCa. METHODS: Medline, Embase, and Cochrane Library databases were searched for relevant studies...

BACKGROUND: The cornerstone of prostate cancer diagnosis remains the transrectal ultrasound-guided biopsy (TRUS-BX), which most frequently occurs in the office setting under local anesthesia. However, there are now other techniques of prostate biopsy aimed at improving outcomes such as patient comfort, significant cancer detection, and infectious complications. The purpose of the present study is to compare the cost and efficacy outcomes of five different approaches. METHODS: We compared the comprehensive costs of a random sample size of 20-30 cases from each of the following: (1) local anesthesia TRUS-BX (reference), (2) sedation TRUS-BX, (3) general anesthesia transperineal template biopsy (TP), (4) sedation MRI-TRUS fusion biopsy (FB), and (5) sedation in-bore MRI biopsy (IB-MRI)...

BACKGROUND: Non-Hispanic Black (NHB) men are at an increased risk for aggressive prostate cancer (PCa), making active surveillance (AS) potentially less optimal in this population. This concern has not been explored in other minority populations-specifically, Hispanic/Latino men. We recently found that Mexican-American men demonstrate an increased risk of PCa-specific mortality, and we hypothesized that they may also be at risk for an adverse outcome on AS. METHODS: Using the Surveillance, Epidemiology, and End Results (SEER) program, we extracted a population-based cohort of men diagnosed from 2004 to 2013 with localized or regional PCa, who had ≤2 cores of only Grade Group (GG) 1 cancer, and underwent radical prostatectomy (RP) with available biopsy and surgical pathology results...

PURPOSE: Recent evidence suggests that statins may improve prostate cancer outcomes; however, their role in active surveillance (AS) is poorly characterized. We aimed to evaluate the association between statin use at diagnosis and time to progression on AS. MATERIALS AND METHODS: Data were obtained from a prospectively maintained cohort of men undergoing AS between 1995 and 2016 at our institution. All men satisfied the low-risk criteria: Gleason score <7, <4 positive cores, <50% involvement of any core, and prostate-specific antigen level <10...

BACKGROUND: Patients with metastatic prostate cancer have poor prognosis. In this study, we compared the addition of abiraterone, docetaxel, bisphosphonate, celecoxib or combinations to standard ADT vs. ADT alone for patients with mHSPC in terms of overall survival (OS), failure-free survival (FFS), and adverse events. METHODS: We searched PubMed and performed a network meta-analysis to generate probabilistic inferences and provide efficacy rankings in terms of posterior hazard ratios with 95% credible intervals (CrI), surface under the cumulative ranking curve (SUCRA), probability better than competing treatments, and probability best...

BACKGROUND: Intermediate endpoints are needed in early phase studies of men with metastatic castration-resistant prostate cancer (mCRPC) that can reliably predict success in phase 3 trials. Among men with measurable disease, objective response may provide information as to whether a treatment is likely to be successful. METHODS: We conducted a systematic review of systemic agents that have proceeded to phase 3 trials in men with mCRPC and examined the relationship between improvements in measurable disease response in phase 2 trials and successful phase 3 trials leading to regulatory approval...

OBJECTIVE: To determine the prognostic value of serum chromogranin-A (CGA) in a two-cohort study of men with metastatic castrate resistant prostate cancer (mCRPC) and to compare with circulating tumor cells (CTCs)-based prognosis. PATIENTS AND METHODS: A two-cohort-based evaluation for serum CGA for prognostication in CRPC stage was performed using a screening cohort of 256 men with mCRPC and an independent validation cohort of 92 men with mCRPC. In both cohorts, men receiving proton pump inhibitors and those with non-castrate levels of testosterone (>50 ng/dl) were excluded...

BACKGROUND: The human microbiome may influence prostate cancer initiation and/or progression through both direct and indirect interactions. To date, the majority of studies have focused on direct interactions including the influence of prostate infections on prostate cancer risk and, more recently, on the composition of the urinary microbiome in relation to prostate cancer. Less well understood are indirect interactions of the microbiome with prostate cancer, such as the influence of the gastrointestinal or oral microbiota on pro- or anti-carcinogenic xenobiotic metabolism, and treatment response...

BACKGROUND: Recent studies suggested that the relation between night-shift work and prostate cancer may differ between rotating and fixed schedules. OBJECTIVES: We aimed to quantify the independent association between night-shift work and prostate cancer, for rotating and fixed schedules. METHODS: We searched MEDLINE for studies assessing the association of night-shift work, by rotating or fixed schedules, with prostate cancer. We computed summary relative risk (RR) estimates with 95% confidence intervals (95% CI) using the inverse variance method and quantified heterogeneity using the I2 statistic...

OBJECTIVE: Androgen deprivation therapy (ADT) is a common treatment option for men with biochemical relapse from prostate cancer. ADT is associated with changes in mood, cognition, and quality of life, and most recently with increased risk for Alzheimer's disease (AD). This study examined changes in brain metabolism using positron emission tomography (PET) in men undergoing intermittent ADT. METHODS: Nine men with prostate cancer and a rising PSA (biochemical recurrence) without evidence of metastases were treated with intermittent ADT consisting of 9 months of complete androgen blockade achieved with combined leuprolide acetate and flutamide...
