How is active myeloma defined?
In the past, multiple myeloma was defined by four important "CRAB" features: Calcium, Renal, Anemia, and Bone Lesions. Each of these helps determine if you have myeloma in addition to a higher-than-normal monoclonal protein.
Calcium: Calcium levels that are 1 mg/dl above normal levels or over 11 mg/dl
Renal Issues: Creatinine levels over 2 mg/dl
Anemia: If the hemoglobin number is more 2 grams/dl below normal or total hemoglobin less than 10 g/dl
Bone Lesions: More than one lesions detected by x-ray, CT or PET scan
In time, myeloma experts decided that the CRAB criteria were not quite enough to define active disease, so they added three more "myeloma defining events."
Muzaffar Qazilbash, MD of MD Anderson Cancer Center joins HealthTree University to share how myeloma doctors define active disease.
