Hi Kevin, - The contents of your Post are a little confusing, but if I understand it correctly, a single Biopsy sample (of 12) was found to contain malignant cells that were assigned a Gleason GRADE of 3. Since only GRADE 3 was present both the Primary and Secondary Grades were assigned that GRADE, resulting in a Gleason SCORE of (3+3)=6. This is essentially the lowest Gleason SCORE presently identified with modern application in Biopsy Prostate tissue samples.
The reference to PIN that you cite, simply indicates that the sample in question stained "negatively" for high grade PIN which although not meeting the criteria to be called malignant, which is thought by many to be a precurser to eventual malignancy. and can sometimes mimic malignant cells to less specialized Pathologists. AMACR is overly expressed in Cancerous tissue but is not usually present in benign (non-cancerous) tissue and the thus I ASSUME that its reference refers to a positive AMACR finding, thus tending to confirm the malignancy diagnosis and thereby eliminating the finding of PIN.
In light of the above, I would definitely suggest that you ask that the Biopsy slides be sent to a recognized expert Pathologist that specializes in the examination of Prostate tissue. One that immediately comes to mind is:
Johns Hopkins Medical Institutions
Anatomic Pathology Consultation Service
1620 McElderry Street
Reed Hall, Room 315
Baltimore, MD 21205
Phone 410-955-5043
Fax 443-287-3818
This service is dedicated to consulting and rendering second opinions on such samples and is headed by Jonathan Epstein, MD, who is one of the most respected of such experts. It has 2 other experienced staff Pathologists in Drs Netto and Lotan. Dr Netto specializes in Urologic pathology and co-authored, with Dr. Epstein, the 4th edition of "Prostate Biopsy Interpretation". He also has specific expertise in the molecular aspects of Urologic pathology, which includes AMACR that your Post mentioned.
The second opinion should help clarify the practicality of Active Surveillance (AS) as a pragmatic approach in your case, if it is found that PCa is confirmed on consultation. I hope that all this is not too complicated to understand, but if you need further clarification, I will be happy to respond. Good luck to you and I wish you the best results possible. -
