Gleason grading

A survey on jpg images illustrating Gleason scores of cancers diagnosed on needle biopsy was circulated among ENUP members in 2011. The main purpose of the quiz was to standardize the reporting of the clinically important transition from Gleason score 6 to 7.
Under Introduction and Summary the design and results of the survey are presented. The images are posted with comments under the Gleason links below. The results were published in Standardization of Gleason grading among 337 European pathologists (Histopathology, 2013).
