Five years after the last prostatic carcinoma grading consensus conference of International Society Urological Pathology (ISUP), accrual new data and modification clinical practice require an update current pathologic guidelines. This manuscript summarizes proceedings ISUP meeting for held in September 2019, Nice, France. Topics brought to included following: (1) approaches reporting Gleason patterns 4 5 quantities, minor/tertiary patterns, (2) agreement report presence invasive cribriform...

Invasive cribriform and intraductal carcinoma in radical prostatectomy specimens have been associated with an adverse clinical outcome. Our objective was to determine the prognostic value of invasive pre-treatment biopsies on time disease-specific death. We pathologically revised diagnostic 1031 patients from first screening round European Randomized Study Screening for Prostate Cancer (1993–2000). Ninety percent all (n=923) had received active treatment, whereas 10% (n=108) followed by...

Invasive cribriform and intraductal carcinoma (CR/IDC) is associated with adverse outcome of prostate cancer patients. The aim this study was to determine the molecular aberrations CR/IDC in primary cancer, focusing on genomic instability somatic copy number alterations (CNA). Whole-slide images Cancer Genome Atlas Project (TCGA, N = 260) Canadian Prostate Network (CPC-GENE, 199) radical prostatectomy datasets were reviewed for Gleason score (GS) presence CR/IDC. Genomic assessed by...

To assess the interobserver reproducibility of individual Gleason grade 4 growth patterns.Twenty-three genitourinary pathologists participated in evaluation 60 selected high-magnification photographs. The selection included 10 cases 3, 40 (10 per pattern), and 5. Participants were asked to select a single predominant case (3, 4, or 5), indicate pattern, if present. 'Consensus' was defined as at least 80% agreement, 'favoured' 60-80% agreement. Consensus on grading reached 47 (78%) cases, 35...

Microscopic evaluation of prostate specimens for both clinical and research purposes is generally performed on 5-μm-thick tissue sections. Because cross-sections give a two-dimensional (2D) representation, little known about the actual underlying three-dimensional (3D) architectural features benign cancer (PCa). The aim this study was to show that combination tissue-clearing protocols confocal microscopy can successfully be applied investigate 3D architecture human tissue.Optical clearing...

Nerve-sparing (NS) radical prostatectomy (RP) results in better functional outcomes. Intraoperative neurovascular structure-adjacent frozen section examination (NeuroSAFE) significantly increases the frequency of NS surgery. The effect NeuroSAFE on postoperative erectile function (EF) and continence is not yet clear.

Objectives To assess the metastasis‐free survival ( MFS ) and disease‐specific DSS in men with Gleason score ≤6 prostate cancer at radical prostatectomy RP ). Patients Methods We included 1101 consecutive patients operated between March 1985 to July 2013 a single institution. The outcome variables were . postoperative was estimated by Kaplan–Meier method. Results distribution of study population (1101 patients) (449, 41%), 3 + 4 = 7 (436, 40%), (99, 9%) 8–10 (117, 11%). median (interquartile...

Intraductal carcinoma of the prostate (IDC-P) has been recently recognized by World Health Organization classification prostatic tumors as a distinct entity, most often occurring concurrently with invasive adenocarcinoma (PCa). Whether documented admixed PCa or in its rare pure form, numerous studies associate this entity clinical aggressiveness. Despite increasing experience and requirement IDC-P documentation protocols for synoptic reporting, specifics potential contribution to assessment...
