Initial experience with identifying high-grade prostate cancer using diffusion-weighted MR imaging (DWI) in patients with a Gleason score ≤ 3 + 3 = 6 upon schematic TRUS-guided biopsy: a radical prostatectomy correlated series.

Introduction: Diffusion-weighted magnetic resonance (MR) imaging (DWI) might be able to fulfill the need to accurately identify high-grade prostate carcinoma, in patients initially selected for active surveillance in the Prostate Specific Antigen (PSA) screening era based on transrectal ultrasound-guided biopsy Gleason score. We aimed to determine whether DWI is able to correctly identify those patients with a biopsy Gleason score of ≤ 3 + 3 = 6, but harboring Gleason 4 and/or 5 components in their radical prostatectomy (RP) specimen.

Materials And Methods: Whole-mount RP specimens were used to identify regions of interest corresponding with tumor on the DWI-derived apparent diffusion coefficient (ADC) maps in 23 patients with a Gleason ≤ 3 + 3 = 6 on biopsy.

Downstaging of TURBT-Based Muscle-Invasive Bladder Cancer by Radical Cystectomy Predicts Better Survival.

Differences between clinical (cT) and pathological tumor (pT) stage occur often after radical cystectomy (RC) for muscle-invasive bladder cancer. In order to evaluate the impact of downstaging on recurrence and survival, we selected patients from a large, contemporary, population-based series of 1,409 patients with MIBC. We included all patients who underwent RC (N=643) and excluded patients who received (neo)adjuvant therapy, those with known metastasis at time of diagnosis, and those with nonurothelial cell tumors.

Biomarkers for the diagnosis of prostatic inflammation in benign prostatic hyperplasia.

Background: Chronic prostatic inflammation could be a central mechanism in benign prostatic hyperplasia (BPH) progression. Currently, the histological examination of prostate biopsies remains the only way to diagnose prostatic inflammation. Our objective was to find new noninvasive biomarkers for the diagnosis of prostatic inflammation.

Body mass index is not a predictor of biochemical recurrence after radical prostatectomy in Dutch men diagnosed with prostate cancer.

Purpose: To determine the effect of body mass index (BMI) on clinical and pathological characteristics at time of diagnosis and on risk of biochemical recurrence after radical prostatectomy among Dutch men diagnosed with prostate cancer.

Methods: In total, 1,116 prostate cancer patients with known BMI, diagnosed between 2003 and 2006, were identified from the population-based cancer registry held by the Comprehensive Cancer Centre East, The Netherlands. Of these, 504 patients underwent a radical prostatectomy.

Brachytherapy versus cystectomy in solitary bladder cancer: a case control, multicentre, East-Netherlands study.

Purpose: Comparing the outcome of surgery and brachytherapy-based radiotherapy in patients with solitary T1G3/T2 bladder tumour in, a retrospective case-control study, because efforts for a randomised clinical trial comparing these modalities have failed.

Materials And Methods: Cystectomy group. Patients were selected using the pathological registration system (PALGA).
