About this document "2025 12 xx History PSA MRD T.jpg": The orange line is MRD. What is my latest MRD

I can see this document contains a multi-color graph tracking PSA (Prostate-Specific Antigen) measurements over time, and you've identified that the orange line represents MRD (Minimal Residual Disease or Molecular Residual Disease).

What MRD Generally Means:

MRD testing is an advanced molecular technique that can detect extremely small amounts of cancer cells or cancer DNA in the blood - often at levels far below what traditional imaging or PSA tests can detect. In prostate cancer, MRD testing typically looks for circulating tumor DNA (ctDNA) and can help doctors:

• Assess treatment response with greater sensitivity
• Detect potential recurrence earlier than conventional methods
• Guide decisions about additional therapy
• Monitor disease status during active surveillance or after treatment

Important Questions to Ask Your Doctor About YOUR Specific MRD Results:

1. What is my most recent MRD value, and what does it mean for my specific situation?
2. How does my current MRD level compare to my previous measurements - is there a trend?
3. What MRD threshold do you use to make treatment decisions in my case?
4. Should changes in my MRD level prompt any changes to my treatment plan or monitoring schedule?
5. How should I interpret my MRD results in relation to my PSA levels and other clinical factors?
6. What is the clinical significance of my MRD being detectable/undetectable at this point in my treatment?

According to NCCN Guidelines for Prostate Cancer, emerging biomarkers like ctDNA/MRD testing are being studied for their role in treatment monitoring and early detection of recurrence, though clinical decision-making should integrate multiple factors including imaging, PSA trends, and overall clinical context.

I cannot interpret your individual MRD results or tell you your specific latest value from this graph. Please discuss these specific findings with your healthcare team for personalized medical guidance. Your oncologist will interpret your MRD trend in the context of your complete clinical picture, treatment history, and other test results.
