Minimal Residual Disease (MRD)
The ability to measure minimal residual disease (MRD), which is the number of multiple myeloma (MM) cells remaining after treatment, is important for prognosis. Being able to determine how many MM cells are present will ultimately allow your oncologist to determine how well a treatment is working. Performing these tests over time can show how long the effects of treatment will last. Incredibly sensitive techniques to detect MM cells have been developed, and recent data have shown that patients who achieve a deep response to therapy with no detectable MRD (MRD-negative status) have greater survival rates.
