Biopsy GS variations
I have a question? What is actually my GS diagnosis ? I have varying numbers in my reports.
My biopsy for diagnosis before RP was:
7 cores
3 cores Benign
4 cores GS 5+4=9 (5)
=================•
My RP report biopsy on tumor after RP has this:
Grade Group and Gleason Score
Grade Group
Grade Group 3 (Gleason Score 4+3=7)
Minor Tertiary Pattern 5 (less than 5%): Present
Percentage of Pattern 4 in Gleason score 7: 70%
RP report also has this:
Prostate, radical prostatectomy: Prostatic acinar adenocarcinoma, (Grade group 4, Gleason pattern 4 + 4) forming a
4.5 x 2.2 x 1.7 cm mass involving right and left prostate and extending to the right seminal vesicles. Left posterior apex
margin involved by carcinoma (4 + 4) <1mm and left anterior apex margin (3 + 4), 3 mm. All other margins are negative
for tumor.
