[Evolution of the number of incident cases, stage and first treatments for prostate cancer in France between 2001 and 2016].

Introduction: No studies of French hospital registries for prostate cancer (PCa) have been published since the 2012 USPSTF recommendations.

Material: This is a multicenter cohort study based on hospital data of prostate biopsies (PB) in 3 health centers between 2001 and 2016. The main objective is to describe the evolution of incident cases of PCa.

Quantified analysis of histological components and architectural patterns of gleason grades in apparent diffusion coefficient restricted areas upon diffusion weighted MRI for peripheral or transition zone cancer locations.

Purpose: To quantify and compare the histological components and architectural patterns of Gleason grades in cancerous areas with restriction on apparent diffusion coefficient (ADC) maps.

Materials And Methods: Twelve consecutive cases with 14 separate ADC restriction areas, positive for cancer in the peripheral zone (PZ) and transition zone (TZ) were included. All had 3 Tesla MRI and radical prostatectomy.

Understanding the pathological implications of MRI: application to focal therapy planning.

Purpose Of Review: The current challenge in prostate cancer (PCa) focal therapy indication and planning is how to accurately estimate tumor parameters such as volume, extent and grade. In addition to biopsy results, MRI provides an estimation of PCa contour, volume and histopathological characteristics such as presence of high Gleason grade. Among MRI sequences, diffusion-weighted imaging with apparent diffusion coefficient map is the sequence that showed the best results for cancer aggressiveness characterization.

[Evolution of the number of incident cases of prostate cancer in France from 2001 to 2012 from 5 hospital centers].

Objectives: The main objective is the study of the evolution of the number of incident cases of prostate cancer in France from 2001 to 2012 from 5 hospital centers of urology. The secondary objective is to describe the characteristics of the incident cases and to compare them to those of the patients of the national registers of cancer for the period.

Material And Methods: Prospective observational multicentric study from 01/01/2001 to 31/12/2012 of databases in 5 French, public and private hospital centers of urology.
