Your treatment aims to reduce the number of myeloma cells to as few as possible. This is called remission.
There are different levels of response:
- complete remission (CR) – the paraprotein cannot be detected in blood or urine tests and there are fewer than 5% plasma cells (a type of white blood cell) in the bone marrow
- partial remission (PR) – the paraprotein level is at least 50% lower than it was before treatment
- stable disease – the paraprotein remains at the same level as it was before treatment.
