What is minimal residual disease in myeloma?

Minimal residual disease definition

In multiple myeloma, MRD refers to myeloma cells that are present in the bone marrow after a clinical response has been measured and the patient is in remission. These residual myeloma cells are clinically relevant, as they may lead to disease progression and relapse.

Treatments which specifically target MRD can include:
  1. intensive conventional treatment with more drugs, or a different combination of drugs.
  2. stem cell transplant, e.g. marrow transplant. ...
