OBJECTIVES: The study aimed to evaluate the prediction of Prostate Imaging Reporting and Data System (PI-RADS) with respect to the prostate cancer (PCa) detection rate and tumor aggressiveness in magnetic resonance imaging (MRI)/ultrasound-fusion-biopsy (fusPbx) and in systematic biopsy (sysPbx). MATERIALS AND METHODS: Six hundred and twenty five patients undergoing multiparametric MRI were investigated. MRI findings were classified using PI-RADS v1 or v2. All patients underwent fusPbx combined with sysPbx (comPbx)...

Purpose To evaluate the cost-effectiveness of multiparametric diagnostic magnetic resonance (MR) imaging examination followed by MR imaging-guided biopsy strategies in the detection of prostate cancer in biopsy-naive men presenting with clinical suspicion of cancer for the first time. Materials and Methods A decision-analysis model was created for biopsy-naive men who had been recommended for prostate biopsy on the basis of abnormal digital rectal examination results or elevated prostate-specific antigen levels (age groups: 41-50 years, 51-60 years, and 61-70 years)...

OBJECTIVE: The aim of this study was to evaluate the detection rate for clinically significant prostate cancer (PCa) after multiparametric magnetic resonance imaging (mpMRI)/transrectal ultrasound (TRUS) fusion biopsy versus extended biopsy or saturation prostate biopsy (SPBx) in men enrolled on active surveillance (AS). MATERIALS AND METHODS: From May 2013 to January 2016, 100 men with very low-risk PCa were enrolled on AS. Eligible criteria were: life expectancy greater than 10 years, cT1c, prostate-specific antigen (PSA) below 10 ng/ml, PSA density less than 0...

Medical imaging of the 3 most common genitourinary (GU) cancers-prostate adenocarcinoma, renal cell carcinoma, and urothelial carcinoma of the bladder-has evolved significantly during the last decades. The most commonly used imaging modalities for the diagnosis, staging, and follow-up of GU cancers are computed tomography, magnetic resonance imaging (MRI), and positron emission tomography (PET). Multiplanar multidetector computed tomography and multiparametric MRI with diffusion-weighted imaging are the main imaging modalities for renal cell carcinoma and urothelial carcinoma, and although multiparametric MRI is rapidly becoming the main imaging tool in the evaluation of prostate adenocarcinoma, biopsy is still required for diagnosis...

INTRODUCTION: To evaluate the utility of 3 Tesla (3T) pelvic phased-array (PPA) multiparametric magnetic resonance imaging (mpMRI) to predict extracapsular extension (ECE) and seminal vesicle invasion (SVI) and its subsequent effect on radical prostatectomy (RP) surgical margin status. METHODS: A retrospective evaluation was conducted of RP patients who underwent preoperative 3T PPA mpMRI (without endorectal coil) based on clinical probability of adverse pathological features...

INTRODUCTION: The aim of our work was to evaluate the role of multi-parametric MRI (mpMRI) in detection and management of prostate cancer (PC); specifically investigating the efficacy of mpMRI-based biopsy techniques in terms of diagnostic yield of significant prostate neoplasm and the improved management of patient who choose conservative treatments or active surveillance. EVIDENCE ACQUISITION: A systematic and critical analysis through Medline, Embase, Scopus and Web of Science databases was carried out in March 2016, following the PRISMA ("Preferred Reporting Items for Systematic Reviews and Meta-Analyses") statement...

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...

Brachytherapy is an ideal treatment approach for radiorecurrent prostate cancer given the highly conformal treatment. Increasingly, multiparametric magnetic resonance imaging is being utilized to enhance our ability to assess intraprostatic tumor characteristics. This article aims to review the current literature on whole gland salvage brachytherapy for radiorecurrent prostate cancer as well as the methodology and progress towards a focal approach to salvage brachytherapy. Particular emphasis is placed on the potential role of multiparametric MRI in achieving optimal outcomes with focal salvage brachytherapy...

BACKGROUND AND OBJECTIVE: To evaluate the clinical effects of suspicious upstaging on multiparametric magnetic resonance imaging (mpMRI) for improving the quality of Prostate Cancer Research International Active Surveillance (PRIAS) criteria. MATERIAL AND METHODS: A total of 363 patients with low-risk prostate cancer (PCa) were selected from the K-CaP registry (the multicenter Korean PCa Database).

Background:(68)Ga-prostate-specific membrane antigen (PSMA)-11-positron-emission-tomography (PET)/ computer-tomography (CT) represents an advanced method for staging of primary prostate cancer (PCa) and diagnosis of recurrent or metastatic PCa. However, due to the narrow availability of (68)Ga the development of alternative tracers is of high interest. Objective: To examine the value of the new PET tracer (18)F-PSMA-1007 for staging of local disease by comparing it to multiparametric magnetic resonance imaging (mpMRI) and radical prostatectomy (RP) histopathology...

OBJECTIVE: To evaluate the diagnostic performance of the length of the tumor contact with the capsule (LTC) and the apparent diffusion coefficient (ADC) map in the prediction of microscopic extracapsular extension in patients with prostate cancer who are candidates for radical prostatectomy. MATERIAL AND METHODS: We used receiver operating curves to retrospectively study the diagnostic performance of the ADC map and the LTC as predictors of microscopic extracapsular extension in 92 patients with prostate cancer and moderate to high risk who were examined between May 2011 and December 2013...

INTRODUCTION: Transrectal rectal ultrasound (TRUS)-guided systematic biopsy is the gold standard for diagnosis of prostate cancer. However, systematic biopsy has high false-negative rate and often misses anteriorly located tumors. Magnetic resonance imaging (MRI)-TRUS fusion biopsy can potentially improve cancer detection by better visualization and targeting of cancer focus. We evaluated the role of fusion biopsy in detection of prostate cancer and the association of prostate imaging reporting and data system (PI-RADS) score for predicting cancer risk and its aggression...

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: 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: High intensity focused ultrasound (HIFU) has been used since the beginning of the 1990s as an alternative treatment for prostate cancer. OBJECTIVE: Overview of the current status and critical review of the different indications for HIFU in the treatment of prostate cancer. MATERIAL AND METHODS: Review of the current literature on the indications, side effects, oncologic results and current guideline recommendations. RESULTS: The principle of HIFU is based on high energy sound waves, which lead to coagulation necrosis at the focal point...
