Core percentages are only a rough indicator, of course, because they are so dependent on how directly the biopsy doc hit a tumor. I had one core at 100% but post-op pathology showed only 5% involvement overall.
If you really do have Gleason 7, though, I think core percentage is an academic issue. Gleason 7 is generally considered a ticket to the treatment phase. With your profile the odds of a good outcome are excellent.
