What Is MRD?
- Measurable residual disease (also known as minimal residual disease), or MRD, is an important concept in the treatment of blood cancers.
- Since blood cancers arise from the bone marrow (where all the blood-forming cells in your body originate), doctors need to sample your bone marrow from time to time to see what the state of your cancer is.
- Reaching an MRD-negative status has good implications for prognosis and may affect the timing of your transplant (if planned). To assess for MRD, doctors use advanced techniques to test your bone marrow for residual cancer.
Like all cancers, leukemia cells will tend to "hide" in your body at low levels.

- Even if you reach a "complete remission," this does not mean you are "cancer-free."
- Physicians do not like to use the words "cancer-free" or "cure" until at least five years after they cannot find acute myeloid leukemia in your body.
- Doctors use advanced techniques to test your bone marrow for residual cancer.
- These sensitive tools can detect even one cancer cell in the few million cells that we sample.
Interpreting the results:
- If doctors cannot find evidence of cancer using these tools, then you are "MRD-negative."
- If you are MRD-positive, don't worry being MRD-positive does not mean you cannot be cured of your cancer. Your physician has various strategies to help you achieve an MRD-negative status if needed.
You should ask your physician if MRD-testing is appropriate for you. Since this is a newer tool, some oncologists may not be aware of it or have not used it in their decision-making yet. Therefore, we recommend seeking a second opinion from a large academic hospital that treats a lot of leukemia patients for guidance. Due to the availability of virtual visits now, a leukemia specialist at an academic hospital can easily see you and provide guidance directly to your local oncologist.
