Stephan L. Werner, M.D., F.A.C.S. When the pathologist looks at the biopsy he grades the cancer by comparing the appearance of the cancer cells to the appearance of normal prostate tissue. The grades go from Grade 1, almost normal, to Grade 5, very abnormal. The Pathologist then adds the results from the two greatest areas of cancer and gives a report, for example, (3+2=5). Therefore positive biopsies run from Gleason grade 2, which has a relatively good prognosis, to Gleason grade 10, which does not. The vast majority of prostate cancers are Gleason grade 6 -7, or moderate. It is virtually impossible to make a diagnosis of Grades 2 to 4 on needle biopsy. The lowest grade reported on needle biopsy is (2+3)=5.
