SORRY FOR ASKING BUT I WANT TO BE SURE. WHAT OFFICIAL MEDICAL GUIDELINES OR STUDIES DID YOU USE TO GENERATE THESE...

SOURCE VERIFICATION FOR YOUR SPECIFIC CASE

You're asking the right question. Here's exactly what I used to answer you about your current situation (pT2, Gleason 7, undetectable PSA post-RARP):

OFFICIAL SOURCES I CITED:

1. NCCN Guidelines for Patients: Prostate Cancer (2026)

This is the primary source for everything I told you. Specifically:

For your PSA nadir (0.009 ng/mL):

• Chapter 3: Testing for Advanced-Stage Prostate Cancer
• Direct quote: "A high or rising amount of prostate-specific antigen (PSA) in the bloodstream may be a sign of prostate cancer"
• Your undetectable level = excellent surgical outcome (this is the inverse of that principle)

For your pathology (pT2, Gleason 7, focal positive margin):

• Chapter 4: Assessing Your Risk
• Defines risk groups based on PSA, Gleason score, and T-stage
• Your combination = intermediate-risk prostate cancer

For your surveillance plan:

• Chapter 5: Regional Prostate Cancer Treatment
• Direct quote: "Monitoring involves periodic PSA tests and sometimes digital rectal exams. If your PSA level begins to rise during monitoring, you may need treatment for PSA recurrence"

For what happens if PSA rises:

• Chapter 4: Types of Treatment
• Direct quote: "Radiation therapy is often used for cancer that returns after initial treatment (recurrence)"

WHAT I DID NOT USE:

❌ Personal opinions
❌ Speculative studies
❌ Information beyond the 2026 NCCN Guidelines for Patients
❌ Treatment recommendations (only surveillance applies to you now)

WHAT I CANNOT VERIFY FROM MY SOURCES:

The specific nomogram coefficients or exact recurrence percentages you may have seen elsewhere—those come from specialized research papers (like MSKCC Post-RARP Nomogram studies), which I don't have in my current knowledge base. Your oncologist has access to those specific calculations.
