Sorry I mixed the two up. Thanks for the correction.
Dr. Strum published the general ranges several years ago. Basically G6 give off the most PSA for the volume and G10 gives off the least. He Used an average scale that went 4,3,2,1, and.5 for G6 through G10. A benign prostate gives off .066 per cc of volume.
For example a man with a 30cc prostate should give a PSA of about
1.98. Let's say he had a PSA of 5 and was G7. This would mean the PSA from cancer is 3 and using the scale would indicate about
1cc in volume. Maybe the size of a pea. If it were a G9 it would result in about
3cc of volume, three times the tumor load. My docs estimated about
19cc based on the PSA, G of each core and involvement of each core. They backed off this a bit as my white blood count was high and could indicate some prostatitis. In any event the PSA indicated a significant tumor load.
PSA 59 on 8-26-2010 age 60. Biopsy 9-8-2010 12/12 positive, 20-80% involved, PNI in 3 cores, G 3+3,3+4,and 4+3=G7, T2b.

PSA < .1 since February 2011
