Multiple Myeloma: Symptoms, Causes, Stages, and Life-Saving Treatments
Multiple Myeloma is a rare but aggressive blood cancer that begins in plasma cells, a type of white blood cell found in the bone marrow. These cells are crucial for producing antibodies that fight infection. However, when they become cancerous, they grow uncontrollably, crowding out healthy cells and releasing abnormal proteins that can damage bones, kidneys, and the immune system.
Unlike other cancers that form solid tumors, multiple myeloma spreads within the bone marrow, leading to widespread skeletal and systemic complications. But there is hope—advancements in diagnosis and treatment, especially in targeted therapies and immunotherapy, are transforming outcomes and offering new hope for patients and families.
In this comprehensive guide, we will explore what multiple myeloma is, its causes, risk factors, symptoms, staging, diagnostic tests, treatment options including stem cell transplant and CAR-T therapy, survival rates, financial support systems, and long-term care strategies.
What Is Multiple Myeloma?
Multiple Myeloma (MM) is a cancer of the plasma cells, which are a type of immune cell responsible for producing antibodies (also called immunoglobulins). In MM, the body starts producing large numbers of abnormal plasma cells that accumulate in the bone marrow. These dysfunctional cells suppress the production of healthy blood cells and produce a harmful antibody known as monoclonal protein (M protein).
This buildup of abnormal proteins leads to:
- Weakened bones and fractures
- Increased risk of infections
- Anemia and fatigue
- Kidney damage due to protein overload
Myeloma is referred to as “multiple” because it often affects many bones in the body—commonly the spine, pelvis, ribs, and skull.
Causes of Multiple Myeloma
The exact cause of multiple myeloma remains unknown. However, research suggests that it arises from a combination of genetic mutations and environmental triggers that cause plasma cells to multiply abnormally and escape natural cell death.
Contributing Factors May Include:
- DNA mutations within bone marrow cells
- Chronic immune system stimulation
- Exposure to radiation, herbicides, and toxic chemicals such as benzene
- Abnormal bone marrow microenvironment
- Underlying precancerous conditions like MGUS (Monoclonal Gammopathy of Undetermined Significance)
While these triggers don’t guarantee the development of myeloma, they significantly increase the likelihood of abnormal cell growth and disease progression.
Risk Factors for Multiple Myeloma
While the disease can affect individuals without any known risk factors, certain characteristics are associated with higher incidence:
- Age: Most patients are diagnosed after age 60.
- Gender: Men are slightly more likely to develop the disease than women.
- Ethnicity: African Americans have a higher risk—almost twice as likely as Caucasians.
- Family History: A close relative with multiple myeloma or MGUS increases your risk.
- Weight and Lifestyle: Obesity, poor diet, and sedentary habits may increase inflammation and immune dysregulation.
- Occupational Exposure: Workers in the petroleum, farming, and rubber industries may be more exposed to cancer-causing agents.
Understanding your personal risk profile is the first step toward proactive monitoring and early detection.
Early Signs and Symptoms of Multiple Myeloma
The early symptoms of multiple myeloma can be subtle and easy to miss. Many patients attribute them to age, arthritis, or chronic fatigue—until the disease significantly progresses.
Common Early Symptoms Include:
- Persistent bone pain – especially in the back, ribs, hips, or skull. This is due to bone weakening and lesions.
- Frequent infections – resulting from a weakened immune system.
- Fatigue and weakness – often due to anemia caused by reduced red blood cell production.
- Unexplained weight loss – a systemic sign of cancer.
- Bruising or bleeding – caused by low platelet counts.
- Numbness or tingling – compression of the spinal cord may cause neurological symptoms.
- Kidney problems – such as increased creatinine levels, due to M protein buildup.
Early recognition of these symptoms—especially in those with risk factors—can significantly improve the chance of early intervention and better outcomes.
Staging of Multiple Myeloma
Staging determines the extent of disease progression, guides treatment planning, and predicts prognosis.
Revised International Staging System (R-ISS):
- Stage I:
- Low levels of beta-2 microglobulin (<3.5 mg/L)
- Normal albumin levels (≥3.5 g/dL)
- Normal LDH levels
- No high-risk genetic abnormalities
- 5-year survival: ~82%
- Stage II:
- Intermediate levels of biomarkers or missing information
- 5-year survival: ~60%
- Stage III:
- Beta-2 microglobulin ≥5.5 mg/L
- Elevated LDH
- Presence of high-risk genetic abnormalities (e.g., del(17p), t(4;14))
- 5-year survival: ~40%
Each stage reflects a deeper level of bone marrow involvement, increased cancer cell load, and more aggressive disease behavior.
Diagnostic Tests for Multiple Myeloma
A combination of blood tests, imaging, and bone marrow biopsy is used to confirm a diagnosis of multiple myeloma.
Blood Tests:
- Serum Protein Electrophoresis (SPEP): Detects M proteins in the blood.
- Immunofixation Electrophoresis: Determines the type of monoclonal protein.
- Serum Free Light Chain Assay: Measures kappa and lambda light chains.
- Complete Blood Count (CBC): Checks for anemia or thrombocytopenia.
- Calcium and Creatinine Levels: Elevated levels may suggest bone breakdown and kidney damage.
Urine Tests:
- Urine Protein Electrophoresis (UPEP): Identifies Bence Jones proteins (light chains) excreted in urine.
Bone Marrow Biopsy:
- Confirms the diagnosis by showing excess plasma cells (usually >10%).
- Used to assess genetic markers via fluorescence in situ hybridization (FISH).
Imaging Studies:
- X-rays of the skeleton (bone survey)
- MRI, CT scan, or PET scan to detect bone lesions and assess disease spread
Modern Treatments for Multiple Myeloma
Treatment is based on stage, age, health status, and genetic factors. With the rise of personalized oncology, doctors can offer more effective and less toxic therapies.
1. Chemotherapy & Targeted Therapy:
- Induction therapy usually includes a 3-drug regimen:
- Bortezomib (Velcade)
- Lenalidomide (Revlimid)
- Dexamethasone
- These drugs kill cancerous cells while sparing healthy ones and may be combined with other newer agents.
2. Autologous Stem Cell Transplant (ASCT):
- After initial treatment, patients undergo high-dose chemotherapy to kill remaining myeloma cells.
- Their own stem cells are harvested and reinfused, helping rebuild healthy bone marrow.
- This approach improves survival and can lead to long-term remission.
3. CAR-T Cell Therapy:
- One of the most advanced treatments in oncology.
- Involves modifying a patient’s own T-cells to target and destroy myeloma cells.
- Examples include:
- Idecabtagene vicleucel (Abecma)
- Ciltacabtagene autoleucel (Carvykti)
- Suitable for patients with relapsed or refractory disease after standard therapies.
4. Monoclonal Antibodies:
- Daratumumab (Darzalex) and Elotuzumab are used to target specific proteins on cancerous plasma cells.
- These drugs often work synergistically with standard regimens to boost treatment effectiveness.
5. Supportive Therapies:
- Bisphosphonates to prevent bone fractures
- Antibiotics and antivirals to prevent infections
- Erythropoietin to combat anemia
- Pain management and physical therapy for quality of life
