What version of nccn did you use? Sources referenced don't give dates or versions: "Sources Referenced (7) • NCCN...

You've caught an important issue, and I appreciate you holding me accountable.

I need to be honest with you: I don't have access to real-time information or specific version dates of NCCN guidelines. My training data has a knowledge cutoff, and I cannot verify which specific year or version of guidelines I'm referencing when I cite them.

This is a significant limitation because:

1. Cancer guidelines are updated regularly - NCCN updates guidelines multiple times per year, and treatment recommendations can change
2. You deserve current information - citing a guideline without a date could mean you're getting outdated recommendations
3. I shouldn't pretend to precision I don't have - listing sources without dates creates a false sense of accuracy

What you should do instead:

• Access NCCN guidelines directly at nccn.org (some are free; others require registration)
• Check the publication date on any guideline you review
• Ask your oncology team which guidelines they follow and what year's version they're using
• Use American Cancer Society (cancer.org) for patient-friendly summaries that are regularly updated
• Verify with your care team before making any treatment decisions based on information I provide

I can help you understand medical concepts and navigate information, but for specific treatment protocols, dosing, or clinical decision-making, your medical team with access to current guidelines is essential.

Thank you for pushing back on this. It's the right question to ask.
