OBJECTIVES: To determine the diagnostic value of semiquantitative and quantitative parameters of three functional techniques in multiparametric (mp)-MRI of the prostate. METHODS: Mp-MRI was performed in 110 patients with suspicion of prostate cancer (PCA) before TRUS-guided core biopsy. Peak-enhancement, initial and post-initial enhancement, iAUGC (initial area under gadolinium curve), Ktrans (forward rate constant), Kep (efflux rate constant), Ve (extracellular volume), ADC (apparent diffusion coefficient), and MR spectroscopy ratio were obtained for malignant and benign lesions...

Introduction:(68)Ga PSMA PET CT (PSMA) is increasingly used in men with PSA failure post radical prostatectomy (RP) to triage those who will benefit from salvage radiation treatment (SRT). This study examines the value of PSMA informed SRT in improving treatment outcomes in the context of biochemical failure post RP. Methods: We analysed men with rising PSA post RP with PSA readings between 0.05 and 1.0 ng/ml, considered eligible for SRT at the time of PSMA. For each patient, clinical and pathological features as well as scan results, including site of PSMA positive disease, number of lesions, and a certainty score were documented...

Background Active surveillance (AS) of low-risk prostate cancer (PCa) is an accepted alternative to active treatment. However, the conventional diagnostic trans-rectal ultrasound guided biopsies (TRUS-bx) underestimate PCa aggressiveness in almost half of the cases, when compared with the surgical specimen. Purpose To investigate if additional multi-parametric magnetic resonance imaging (mpMRI) of the prostate and MRI-guided in-bore biopsies (MRGB) at AS inclusion would improve selection of patients for active treatment...

Quantitative information of targeted analyte in a complex biological system is the most basic premise for understanding its involved mechanisms, and thus precise diagnosis of a disease if it is a so-called biomarker. Here, we designed and synthesized a neodymium (Nd)-cored tag [1,4,7,10-tetraazacyclododecane-1,4,7-trisacetic acid (DOTA)-Nd complex together with a light-harvesting antenna aminofluorescein (AMF, λex/em = 494/520 nm), AMF-DOTA-Nd] with duplex signals, second near-infrared (NIR) window luminescence (λem = 1065 nm, 2...

BACKGROUND: During the last decade, an inverse stage migration has been observed in radical prostatectomy series at tertiary centers. However, it remains unclear whether similar trends can also be observed in solely robotic practices, including nonreferral centers. The aim of this study was to investigate the clinical and pathological trends in robotic-assisted laparoscopic prostatectomy (RALP) enrollment in Belgium over a period of 6 years through an analysis of a prospective registry...

INTRODUCTION AND OBJECTIVE: With the peritoneum acting as a natural surface for lymphatic reabsorption, transperitoneal robot-assisted radical prostatectomy (tRARP) is thought to be associated with a lower incidence of symptomatic lymphocele (SL) compared to its extraperitoneal counterpart (eRARP) when bilateral pelvic lymph node dissection (BPLND) is performed. Herein, we aim to determine if there is a difference in SL formation and characteristics between the two approaches. METHODS: We reviewed the records of patients who underwent eRARP or tRARP and BPLND at a tertiary care academic center from July 1, 2003 to May 31, 2016...

PURPOSE: Despite increasing use, proton therapy (PT) remains a relatively limited resource. The purpose of this study was to assess clinical and demographic differences in PT use for prostate cancer compared to intensity modulated radiation therapy (IMRT) at a single institution. METHODS AND MATERIALS: All patients with low- and intermediate-risk prostate cancer (N = 633) who underwent definitive radiation therapy between 2010 and 2015 were divided into PT (n = 508) and IMRT (n = 125) comparison groups and compared using χ(2) and independent sample t tests...

PURPOSE: Although already established for very-low and low-risk (LR) prostate cancer (PCa), controversy remains around offering active surveillance (AS) to men with intermediate-risk (IR) PCa. As IR represents a broad spectrum of disease biology, there is a critical need to define eligibility criteria that will enable both patient and physician to accept AS as the best balance of competing risks. In this study, we aimed to identify predictors of progression to enable optimal patient selection...

The role of Sun2 has been described by previous studies in various types of cancers, including breast cancer and lung cancer. However, its role and potential molecular mechanism in the progression of prostate cancer have not been fully elucidated. In the present study, we found that Sun2 expression was reduced in prostate cancer tissues compared with paired normal tissues, and that low expression of Sun2 was significantly correlated with Higher Gleason scores, postoperative T stage (pT), Lymph nodal invasion and Clinical pathological stages...

PURPOSE: To investigate the microvessel density (MVD) and proliferation in prostate cancer (PC) core biopsies. METHODS: Core biopsy samples of PC tissue from 45 patients were routinely processed and embedded in paraffin. The samples of PC formed the investigated group (n=25), while samples of benign prostatic hyperplasia (BPH) served as controls (n=20). From paraffin blocks, 3-5 μm-thick sections were made and routine hematoxylin-eosin method and immunohistochemical ABC method with Ki67 and CD34 antibodies were applied...

Prostate cancer (PCa) is one of the few neoplasms that are not well served by 18F-Fluorodeoxyglucose (FDG) positron emission tomography (PET). As a result, a number of PET tracers have been developed to target particular biological features of PCa. Such agents can be used for diagnosis, staging, identification of biochemical recurrence (BCR) and evaluation of metastatic disease. Here, we focus on primary disease and local staging. To date, magnetic resonance imaging (MRI) has proven superior to PET in the imaging of primary PCa...

MRI-targeted biopsy of the prostate appears to have the potential to reduce the high rates of underdiagnosis and overdiagnosis associated with the current diagnostic standard of transrectal ultrasound guided systematic biopsy. Direct or "in bore" MRI-guided biopsy is one of the three methods for MRI-targeted core needle sampling of suspicious, generally Pi-RADS 4 or 5, foci within the prostate, and our early experience suggests the approach demonstrates substantial utility and promise in the care of patients with prostate cancer...

PURPOSE: Patients with prostate cancer (PCa) containing Gleason pattern (GP) 5 disease experience a greater and earlier incidence of prostate cancer-specific mortality (PCSM) than general PCa patients. This affords the statistical power to compare PCSM outcomes among different treatment modalities even when restricting the analysis to patients treated in the modern era. The purpose of the present study was to compare the survival outcomes among patients with GP 5 PCa on needle core biopsy or transurethral resection of the prostate who underwent extremely dose-escalated radiation therapy (RT; exemplified by external beam RT with a brachytherapy boost [EBRT + BT]) versus radical prostatectomy (RP) in the modern era...

BACKGROUND: Studies on the association between two single nucleotide polymorphisms (SNPs) in estrogen receptor α (ERα), PvuII (rs2234693 T>C) and XbaI (rs9340799 A>G), and the prostate cancer risk are inconsistent. Therefore, we performed a meta-analysis to derive a more accurate estimation of this relationship. METHODS: A literature search of PubMed, Embase, Web of Science databases until October 1, 2016, was conducted. Crude odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to assess the strength of this association...
