Plasma Cell Percent to Smoldering Myeloma Criteria

Apply criteria to distinguish smoldering multiple myeloma (serum M-protein 3 g/dL or above, or bone marrow plasma cells 10–60%) from MGUS and symptomatic MM requiring treatment.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Apply criteria to distinguish smoldering multiple myeloma (serum M-protein 3 g/dL or above, or bone marrow plasma cells 10–60%) from MGUS and symptomatic MM requiring treatment

Each component has a specific meaning:

  • MGUS — The mgus recorded for the scenario being assessed.
  • Symptomatic MM requiring treatment — The symptomatic mm requiring treatment recorded for the scenario being assessed.

Note: Interpret the smoldering myeloma result against the thresholds and context described above.

How to Use

Enter the MGUS, symptomatic MM requiring treatment for the scenario you are assessing. Apply criteria to distinguish smoldering multiple myeloma (serum M-protein 3 g/dL or above, or bone marrow plasma cells 10–60%) from MGUS and symptomatic MM requiring treatment. Use the smoldering myeloma result to inform your calculation.
