Gleason Grade Group 1 Prostate Cancer: Arguments for and Against a Cancer Designation.

One of the critical challenges in managing localized prostate cancer is in balancing the need for appropriate treatment of aggressive disease while avoiding overtreatment of indolent cases.

This article explores the history of the Gleason grading system, histopathologic characteristics of Gleason score 6 disease, and its clinical implications.
