In this series, PathPod gathers pathologists and trainees Around The Scope to discuss their work in depth.

Today, we hear about prostate pathology and how optimization of Gleason grading can improve prognostic information. Our hosts, Dr. Mike Arnold (@MArnold_PedPath) and Dr. Andrew Bellizzi (@IHC_guy) talk with Dr. Jesse McKenney, Dr. Jane Nguyen (@janenguyen44) and Dr. Sean Williamson (@Williamson_SR) of the Cleveland Clinic.

Hear about how PSA screening changed the biopsies that pathologists see, and how the art and science of re-examining Gleason grading refined prognosis for patients with prostate cancer.
