Welcome
As part of an academic research project on virtual microscopy, we here provide a tool for assessing observer variability of Gleason grading of prostate biopsies, as well as  interactive tools for teaching and standardizing grading.

The Gleason grade of 62 digitized prostate biopsies (virtual slides) has been assessed by expert uropathologists. The analysis of their scorings, and a description of this web site
has been published in the
Human Pathology.     More info
