Consensus grade: GS 3+4=7 (ISUP 2)

User Diagnosis Difficulty Comment
Pathologist 1 other Borderline lower

3+5, single cells

Pathologist 2 GS 3+4=7 (ISUP 2) Borderline higher
Pathologist 3 GS 3+4=7 (ISUP 2) Typical
Pathologist 4 GS 3+4=7 (ISUP 2) Borderline higher

There may be a small tertiary pattern 5 present. For ISUP, some would call this a 3+5; I use classic Gleason grading.

Pathologist 5 GS 3+4=7 (ISUP 2) Borderline higher

poorly formed glands

Pathologist 6 GS 3+4=7 (ISUP 2) Borderline higher

poorly formed glands

Pathologist 7 GS 3+4=7 (ISUP 2) Borderline lower

sclerous stroma and tangentila cutting ? of the glands, Some ribriform minor aspects

Pathologist 8 GS 3+4=7 (ISUP 2) Typical

These are the cases that I find most difficult to grade. I don't believe that this is as aggressive as cases with focal cribriform growth, but I feel obligated to give it a "gestalt" 3+4=7 based on current rules. I'm sure that some even consider a higher grade.

Pathologist 9 GS 3+4=7 (ISUP 2) Borderline lower
Pathologist 10 GS 3+4=7 (ISUP 2) Typical
Pathologist 11 GS 3+4=7 (ISUP 2) Typical
Pathologist 12 GS 3+4=7 (ISUP 2) Typical
Pathologist 13 GS 4+4=8 (ISUP 4) Typical

Would grade 3+5

Pathologist 14 GS 3+4=7 (ISUP 2) Borderline higher

Mostly 3 with a minor 4 (irregular strands)

Pathologist 15 GS 3+4=7 (ISUP 2) Typical
Pathologist 16 GS 3+4=7 (ISUP 2) Borderline higher
Pathologist 17 GS 3+4=7 (ISUP 2) Typical

3+ typical poorly formed glands

Pathologist 18 GS 3+4=7 (ISUP 2) Typical
Pathologist 19 GS 3+4=7 (ISUP 2) Borderline higher

Same difficultly with estimating relative proportion of patterns 3 and 4 from images. Some cords of tumour cells are present raising the possibility of grade 5 but several glands are narrowed and angulated ("pinched off") so this is probably tangential sectioning rather than true pattern 5.

Pathologist 20 GS 3+4=7 (ISUP 2) Typical

is this crush artefact making 3 into 4

Pathologist 21 GS 4+3=7 (ISUP 3) Borderline lower
Pathologist 22 GS 3+4=7 (ISUP 2) Typical
Pathologist 23 GS 4+3=7 (ISUP 3) Borderline higher
Pathologist 24 GS 3+4=7 (ISUP 2) Borderline higher
Pathologist 25 GS 4+3=7 (ISUP 3) Borderline higher


Case description (by case creator):

3+4=7 which has a component that may be interpreted as borderline GP5. There are occasional strips of epithelium but there is stromal desmoplasia and some may be compressed glands.
