Diagnosis
Diagnosing multiple myeloma and amyloidosis requires a thorough assessment using lab tests, imaging studies, and biopsies to confirm the presence of disease and guide treatment.
Multiple Myeloma Diagnosis
Blood Tests
Tests include a complete blood count (CBC) to check levels of red and white blood cells, and kidney and calcium levels to assess bone damage and kidney function. Specific markers like M-proteins, immunoglogulins, and free light chains are measured to detect the presence of cancerous plasma cells, including ones that cause blood cancer.
Urine Tests
Urine tests identify Bence Jones proteins, which can signal kidney damage.
Imaging Studies
X-rays, CT scans, MRIs, or PET/CTs are used to evaluate bone health. These imaging studies detect bone damage or lesions caused by cancer.
Bone Marrow Biopsy
The definitive test for multiple myeloma, a bone marrow biopsy, measures the number of cancerous plasma cells and identifies genetic mutations crucial for staging the disease.
Staging
Staging is based on a combination of blood test results and chromosomal abnormalities in plasma cells. This helps classify the disease as Stage I, II, or III, informing treatment choices.
Amyloidosis Diagnosis
Tests are used to detect abnormal amyloid proteins affecting organ function, similar to multiple myeloma.
Tissue Biopsy
A small sample of tissue is taken (often from abdominal fat or affected organs) to confirm amyloid deposits.
Bone Marrow Biopsy
The definitive test for AL (light chain) amyloidosis, a bone marrow biopsy measures the number of cancerous plasma cells and identifies genetic mutations crucial for staging the disease.
Specialized Imaging
Depending on which organs are involved, imaging studies like a cardiac MRI or ultrasound may be used to evaluate organ damage.
Organ Function Tests
Specific tests assess the health of organs like the heart and kidneys, ensuring any amyloid-related damage is accurately diagnosed and managed by the appropriate specialist.
