To evaluate the performance of urinary PCA3 test to predict prostate biopsy outcome in a large French cohort.

A urine sample was prospectively obtained in 1015 patients undergoing prostate biopsies to determine the PCA3 score.

The diagnostic for prostate cancer is changing. To improve the detection of this cancer, urologists expect a lot from the contribution of magnetic resonance imaging (MRI). What is the role of this imaging in prostate cancer detection? This is a retrospective study, from 2011 to 2013, mono-centric and single-operator.

The German S3 guideline on prostate cancer gives recommendations on early detection of prostate cancer. In this study we analyzed the adherence of urologists in private practice from the administrative district of Münster, Germany to this guideline.

Fear of recurrence (FOR) is a key concern among survivors of all cancers. In prostate cancer, FOR varies with health and treatment type, but little is known about how survivors' appraisals of their treatment, and in particular their level of regret over treatment decisions, may affect this.

Multiparametric-magnetic resonance imaging (mp-MRI) is the main imaging modality used for prostate cancer detection. The aim of this study is to evaluate the diagnostic performance of mp-MRI at 1.5-Tesla (1.

The aim of this study was to evaluate the detection rate of bone metastases and the added value of (11)C-acetate (ACE) positron-emission tomography/computed tomography (PET/CT) compared to bone scintigraphy (BS) in high-risk prostate cancer (PC).

To evaluate the efficacy of 11C-choline PET/CT (CHO-PET/CT) based helical tomotherapy (HTT) as a therapeutic approach for bone metastases in recurrent prostate cancer (PCa) patients. METHODS This retrospective study includes 20 PCa patients (median age: 67; range: 51-80 years) presenting biochemical relapse after primary treatment who underwent CHO-PET/CT based HTT on positive bone metastases from December 2007 to June 2014.

The main drawback of 11C-choline PET/CT for restaging prostate cancer (PCa) patients with biochemical failure is the relatively low positive detection rate for prostate specific antigen (PSA) < 1 ng/ml.

aim is outcome of 11C-Choline-PET guided SBRT on lymph node metastases.

patients with 1 - 4 lymph node metastases detected by 11C-choline-PET were treated with SBRT. Toxicity, treated metastases control and Progression Free Survival were computed.

We assessed the value of fusion (18)F-fluoromethylcholine ((18)F-choline) Positron Emission To-mography / Magnetic Resonance Imaging (PET/MRI) for image-guided (targeted) prostate biop-sies to detect significant prostate cancer (Gleason ≥ 3+4) compared to standard (systematic 12-core) biopsies.

There is increasing interest in PET/CT with prostate-specific membrane antigen (PSMA) tracers for imaging of prostate cancer because of the higher detection rates of prostate cancer lesions than with PET/CT with choline.

PURPOSE - In recent years, a new PET compound (anti-3-F-FACBC or F-fluciclovine) was tested for the detection of prostate cancer relapse. Despite very promising results, only preliminary data were available with regard to the comparison to C-choline. The aim of this study was to compare the detection rate of F-FACBC and C-choline in patients presenting a biochemical relapse.

The purpose of this study was to determine whether integrated 18F-fluorocholine (FCH) PET whole-body MRI (PET/WBMRI) depicts lymph node and distant metastases in patients with high-risk prostate cancer more frequently than does conventional staging.

A remarkable therapeutic efficacy has been demonstrated with 225Ac-prostate-specific membrane antigen (PSMA)-617 in heavily pre-treated metastatic castration-resistant prostate cancer (mCRPC) patients.

Although the causes of prostate cancer (PCa) and benign prostatic hyperplasia (BPH) are not known, the role of oxidative stress, aging, and diet are suspected to increase the incidence of prostate complications.

Trans-rectal ultrasound-guided 12-core systematic biopsy (SBx) is the standard diagnostic pathway for prostate cancer (PCa) because of a lack of sufficiently accurate imaging. Quantification of 3-D dynamic contrast-enhanced ultrasound (US) might open the way for a targeted procedure in which biopsies are directed at lesions suspicious on imaging.

We aimed to report on multiparametric MRI (mpMRI) characteristics of post-primary focal cryosurgery (PFC) patients suspected of biochemical recurrence (BCR) by the Phoenix criteria.

We retrospectively reviewed all patients at our institution who had undergone PFC.

Human prostate cancer (PCa) is a highly heterogeneous and multifactorial disease. Current clinical biomarkers are not sufficiently accurate, thus being unable to predict the clinical outcome. Therefore, searching for new biomarkers aiming to improve diagnosis, prognosis and therapy is still required.

To overcome the limitations regarding transrectal ultrasound (TRUS)-guided biopsies in prostate cancer (PCa) detection, there is a focus on new imaging technologies. The Navigo™ system (UC-care, Israel) uses regular TRUS images and electrospatial monitoring to generate a 3D model of the prostate.

Sodium fluoride (NaF) positron emission tomography combined with computer tomography (PET/CT) has shown to be more sensitive than the whole-body bone scan in the detection of skeletal uptake due to metastases in prostate cancer.

Herein we report a low cost, sensitive, supercapacitor-powered electrochemiluminescent (ECL) protein immunoarray fabricated by an inexpensive 3-dimensional (3D) printer. The immunosensor detects three cancer biomarker proteins in serum within 35min.

A preponderance of clinical evidence supports a significant public health benefit for prostate-specific antigen (PSA)-based screening and early detection of prostate cancer in appropriately counseled and selected men.

Randomized clinical trials have shown that use of 5α-reductase inhibitors (5-ARIs) lowers overall prostate cancer (PCa) risk compared to placebo, while the proportion of Gleason 8-10 tumors is elevated.

To determine the value of 68Ga-PSMA-11 PET/CT in men with newly diagnosed prostate cancer (PC).

We analysed results of 140 men with intermediate and high-risk PC. All men underwent 68Ga-PSMA-11 PET/CT and mpMRI prior to radical prostatectomy (RP) with extended pelvic lymph node dissection (ePLND).

68Ga-labelled prostate specific membrane antigen (PSMA) ligand PET/CT is a promising modality in primary staging (PS) and biochemical relapse (BCR) of prostate cancer (PC). However, pelvic nodes or local recurrences can be difficult to differentiate from radioactive urine.

To systematically review currently available data on 68Ga-prostate specific membrane antigen (PSMA) positron emission tomography (PET) used for the primary staging of high-risk prostate cancer.

We performed critical reviews of EMBASE, Web of Science (including MEDLINE) and Cochrane databases in October 2016 according to the Preferred Reporting Items for Systematic Review and Meta-analysis statement.

The early and accurate detection of prostate cancer is important to ensure timely management and appropriate individualized treatment. Currently, conventional imaging has limitations particularly in the early detection of metastases and at prostate-specific antigen (PSA) levels < 2.

The aim of this study was to prospectively compare the detection rate of 68Ga-PSMA versus 11C-Choline in men with prostate cancer with biochemical recurrence and to demonstrate the added value of a tri-modality PET/CT-MRI system.

To examine the detection rates of (68) Ga-PSMA-PET/CT in patients with biochemical recurrence (BCR) after radical prostatectomy (RP), and also the impact on their management.

300 consecutive PC patients who underwent (68) Ga-PSMA-PET/CT between February and July 2015 were prospectively included in the ProCan-I Database.

The present study is based on a retrospective analysis of Gallium-68 (68Ga)-labelled prostate-specific membrane antigen (68Ga-PSMA I&T) PET/CT performed in newly diagnosed, treatment-naïve prostate cancer (PCa) patients prior to definitive treatment.

68Ga-labeled prostate-specific membrane antigen (PSMA) ligand positron emission tomography/computed tomography (PET/CT) has shown promising results in patients with biochemical recurrence after primary therapy for prostate cancer.

68Ga-prostate-specific membrane antigen-11 (68Ga-PSMA-11) is a recently developed positron emission tomography (PET) tracer that can detect prostate cancer (PC) relapses and metastases with high contrast resolution.

68Ga-PSMA PET/CT has an important role in assessment of prostate cancer patients with biochemical recurrence and is evolving in staging high- and intermediate risk disease. The aim of present study was to describe the metastatic patterns and frequency of involved sites of prostate cancer and to assess the incidence of benign Ga68-PSMA avid PET/CT findings in a large patient population.

68Ga ligands targeting prostate-specific membrane antigen (PSMA) are rapidly emerging as a significant step forward in the management of prostate cancer. PSMA is a type II transmembrane protein with high expression in prostate carcinoma cells.

We retrospectively evaluated the utility of (68)Ga-PSMA-11 PET for planning (223)RaCl2 therapy of patients with metastatic prostate cancer and its impact on the therapeutic response as determined by PSA and ALP, as well as the correlation of PSA changes with the results of PSMA-PET, follow-up scans.

68Ga-prostate-specific membrane antigen (PSMA) PET/CT is a promising diagnostic tool for patients with prostate cancer. Our study evaluates SUVs in benign prostate tissue and malignant, intraprostatic tumor lesions and correlates results with several clinical parameters.

The primary aim of this retrospective, single-centre analysis was to assess the performance of 68Ga-PSMA-11 PET/CT in prostate cancer (PCa) patients in early PSA failure after radical prostatectomy (RP).

We evaluated the accuracy of (68)Ga-PSMA-HBED-CC ((68)Ga-PSMA) positron emission tomography/computed tomography (PET/CT) to localize cancer in the prostate and surrounding tissue at initial diagnosis.

The study aims to investigate the presence of physiological prostate-specific membrane antigen (PSMA)-ligand uptake on positron-emission-tomography (PET) in cervical, coeliac and sacral ganglia of the sympathetic trunk as a pitfall for lymph node metastases in prostate cancer imaging.

All types of surgery are associated with complications. The debate is ongoing whether robot-assisted radical prostatectomy can lower this risk compared to open surgery. The objective of the present study was to evaluate post-operative adverse events leading to readmissions, using clinical records to classify these adverse events systematically.

To report on the structure and outcomes of a new 'One Stop' Prostate Clinic (OSPC) designed specifically for rural and remote men.

Prospective cohort study of the first 200 rural or remote men to access a new OSPC at a public tertiary-level hospital in Western Australia between August 2011 and August 2014.

The European Randomized study of Screening for Prostate Cancer (ERSPC) has previously demonstrated that prostate-specific antigen (PSA) screening decreases prostate cancer (PCa) mortality.

To determine whether PSA screening decreases PCa mortality for up to 16yr and to assess results following adjustment for nonparticipation and the number of screening rounds attended.

To validate the 17-gene Oncotype DX Genomic Prostate Score® (GPSTM) biopsy-based gene expression assay as a predictor of adverse pathology (AP, Gleason score [pGS] ≥ 4+3 and/or ≥ pT3) in a prospectively enrolled cohort.

Evidence from numerous cancers suggests that increased aggressiveness is accompanied by up-regulation of signaling pathways and acquisition of properties common to stem cells. It is unclear if different subtypes of late-stage cancer vary in stemness properties and whether or not these subtypes are transcriptionally similar to normal tissue stem cells.

A 17-gene biopsy-based reverse transcription polymerase chain reaction assay, which provides a Genomic Prostate Score (GPS-scale 0-100), has been validated as an independent predictor of adverse pathology and biochemical recurrence after radical prostatectomy (RP) in men with low- and intermediate-risk prostate cancer (PCa).

A significant proportion of patients that fail active surveillance (AS) for prostate cancer management do so because of cancer upgrading. A previously validated upgrading nomogram generates a score that predicts risk of biopsy Gleason 6 upgrading following radical prostatectomy in lower-risk populations that are candidates for Active Surveillance (Cancer, 2013).

This mini-review describes the evolution of the concept of intracrine androgen metabolism by prostate cancer during androgen deprivation therapy. Persistence of androgen receptor protein in the face of castrate circulating levels of testosterone could not be explained fully by hypersensitization or mutation of the androgen receptor.

Robot-assisted radical prostatectomy (RP) has gained remarkable worldwide distribution and has become a standard procedure for localised prostate cancer, indeed a new 'gold standard'. There are proven advantages in reduced blood loss and shorter recovery time.

The identification of new biomarkers to differentiate between indolent and aggressive prostate tumors is an important unmet need. We examined the role of THOR (TERT Hypermethylated Oncological Region) as a diagnostic and prognostic biomarker in prostate cancer (PCa).

Clarifying the mechanisms underlying prostate cancer (PC) progression and resistance to androgen deprivation therapy (ADT) is an urgent clinical issue. ADT influences steroidal metabolism in patients with PC and promotes the accumulation of carbon 21 steroids (C21s), such as progestin.
