Plasma levels of angiogenetic markers in men candidate to prostate biopsy

Correlation between leptin plasmatic levels in non-obese patients and detection rate at prostate biopsy”- Poster P147

Leptin plasma levels in patients undergoing prostate biopsy. a preliminary study in 50 patients

2013

Introduction/Aim: To reduce the number of negative prostate biopsies and to detect clinical significant prostate tumors in patients with elevated serum PSA represent major challenges in urological oncology. Prostate tumors diagnosed in patients with elevated Body Mass Index (BMI) show higher Gleason score and more aggressive biological behavior than those diagnosed in normal population (1). Elevated plasma levels of leptin and other adipose tissue derived factors (adipokines), are evident in obese men (2). Many studies have investigated the role of leptin as a putative molecular mediator between obesity and prostate cancer with contradictory results. Also in normal or overweight (BMI <30) m…

Antibiotic Prophylaxis in Prostate Biopsy

2010

Introduction Prostate biopsy is nowadays one of the most frequent diagnostic procedures in urology. The incidence of bacteraemia, bacteriuria and infective complications is higher after the transrectal procedure than after the transperineal one. A survey demonstrated that 98% of the urologists in USA use antibiotics to prevent infective complications. The transrectal prostate biopsy is the only diagnostic intervention procedure in urology for which an antibiotic prophylaxis is recommended, also for low-risk patients, by the guidelines of the European Association of Urology. If the perineal route is adopted, the antibiotic prophylaxis is recommended only in high-risk patients. Materials and …

Predictors for clinically relevant Gleason score upgrade in patients undergoing radical prostatectomy

2011

Study Type – Diagnostic (exploratory cohort) Level of Evidence 2b What’s known on the subject? and What does the study add? Clinically relevant GSU in the prostatectomy specimen is a common phenomenon. Clinically relevant GSU occurs in one of three patients with clinically ‘very’ low-risk PCa, and a low number of biopsy cores is the key negative predictor. OBJECTIVE • To evaluate clinical predictors for Gleason score upgrade (GSU) in radical prostatectomy (RP) specimen, especially in patients with ‘very’ low risk PCA (T1c and biopsy Gleason score ≤6 and PSA <10 ng/ml and ≤2 positive biopsy cores and PSA density <0.15). Patients and Methods • 402 consecutive patients undergoing RP between 20…

MP43-14 COMPARISON BETWEEN QUINOLONES AND OTHER ANTIBIOTICS IN PREVENTING INFECTIVE COMPLICATIONS IN TRANSRECTAL PROSTATE BIOPSY

INTRODUCTION AND OBJECTIVE:Sepsis is one of the most feared complications of prostate biopsy: it’s incidence is 1-3%. Prevention of infection after biopsy procedure consists in prophylactic antibio...

Clinical and biochemical markers of visceral adipose tissue activity: Body mass index, visceral adiposity index, leptin, adiponectin, and matrix meta…

2018

Context: The correlation between aggressive prostate cancer and obesity mainly based on body mass index (BMI) and pathology after surgery remains controversial. Aims: The aim of the study was to correlate BMI, visceral adiposity index (VAI), and the plasmatic levels of leptin, adiponectin, and matrix metalloproteinase-3 (MMP-3), and biomarkers of adipose tissue function, with the detection of Gleason patterns 4 and 5 at biopsy. Subjects and Methods: Consecutive patients with prostate cancer at 12-core transrectal biopsy were enrolled. BMI, waist circumference (WC), blood samples to evaluate the plasmatic levels of triglycerides (TG) and high-density lipoproteins (HDL), adiponectin, leptin, …

A Shape-based Statistical Method to Retrieve 2D TRUS-MR Slice Correspondence for Prostate Biopsy

2012

International audience; This paper presents a method based on shape-context and statistical measures to match interventional 2D Trans Rectal Ultrasound (TRUS) slice during prostate biopsy to a 2D Magnetic Resonance (MR) slice of a pre-acquired prostate volume. Accurate biopsy tissue sampling requires translation of the MR slice information on the TRUS guided biopsy slice. However, this translation or fusion requires the knowledge of the spatial position of the TRUS slice and this is only possible with the use of an electro-magnetic (EM) tracker attached to the TRUS probe. Since, the use of EM tracker is not common in clinical practice and 3D TRUS is not used during biopsy, we propose to per…
