What is Multiple Myeloma and What Are Its Symptoms

Multiple myeloma, a type of plasma cell neoplasm, is a blood cancer that originates in the bone marrow. In this condition, plasma cells, which typically function to help your body combat infections, begin to grow uncontrollably. This abnormal growth can lead to weakened bones, interfere with blood cell production, and place significant strain on your kidneys.

This plasma cell neoplasm predominantly impacts older adults, with most diagnoses occurring in individuals aged 65 and older. The average age at diagnosis is 69, and it is exceedingly rare in younger individuals, with less than 1% of cases found in those under 35. Early recognition of symptoms is crucial, as it can enhance outcomes and enable more effective management of multiple myeloma.

Key Takeaways

• Multiple myeloma is a type of blood cancer. It mostly affects older people. Finding it early helps with better treatment and results.

• Joining support groups and using learning tools can be helpful. They give advice and support to handle multiple myeloma better.

Symptoms of Multiple Myeloma

Bone Damage

Bone pain and fractures

Bone pain is one of the most common early symptoms of multiple myeloma. You might feel persistent pain, especially in your back, ribs, or hips. This discomfort often worsens with movement or physical activity. Studies show that about 58% of patients report bone pain, with back pain being particularly frequent. In some cases, the disease weakens bones so much that fractures occur even with minor injuries. These are known as pathologic fractures and affect 26% to 34% of patients.

Weakened bones and osteoporosis

Multiple myeloma can cause your bones to lose density, leading to osteoporosis. This happens because the cancerous plasma cells interfere with normal bone remodeling, resulting in fragile bones. Approximately 85% of individuals with this condition experience some form of bone damage, such as osteolytic lesions or thinning bones. If you notice frequent fractures or a stooped posture, it could be a sign of weakened bones.

Blood-Related Symptoms

Anemia and fatigue

Anemia is another common symptom of multiple myeloma. It occurs when the overgrowth of plasma cells crowds out healthy red blood cells in your bone marrow. This type of anemia differs from others, such as iron deficiency anemia, because it stems directly from the cancer's impact on your blood production. You may feel unusually tired, weak, or short of breath. Fatigue affects about 32% of patients and can significantly impact daily life.

Increased risk of infections

Multiple myeloma can also lower your white blood cell count, making it harder for your body to fight infections. You might notice frequent colds, pneumonia, or other illnesses. This happens because the disease suppresses your immune system, leaving you more vulnerable. Infections are a common complication and can become severe if not addressed promptly.

Kidney Issues

Abnormal protein production affecting kidney function

The abnormal proteins produced by cancerous plasma cells can damage your kidneys. These proteins, known as monoclonal proteins or light chains, may form clumps (cast nephropathy) or deposit in kidney tissues, leading to conditions like amyloidosis. Up to 50% of patients with multiple myeloma develop kidney problems during the disease.

Symptoms like swelling and reduced urine output

Kidney damage can cause noticeable symptoms. You might experience swelling in your legs, ankles, or feet due to fluid retention. Reduced urine output or changes in urine color could also indicate kidney issues. If you notice these signs, it’s essential to consult a healthcare provider for further evaluation.

Other Symptoms

High calcium levels (hypercalcemia) causing nausea, confusion, or thirst

High calcium levels, also known as hypercalcemia, can occur when multiple myeloma disrupts normal bone metabolism. This condition causes calcium to leach from your bones into your bloodstream. You might notice symptoms like nausea, excessive thirst, or frequent urination. Confusion, irritability, or even drowsiness may also develop as calcium levels rise.

Hypercalcemia can become severe if left untreated. It may lead to dehydration or kidney damage. If you experience these symptoms, seek medical attention promptly. Addressing hypercalcemia early can prevent complications and improve your overall health.

Neurological symptoms like numbness or weakness

Multiple myeloma can also affect your nervous system. Peripheral neuropathy, a condition that damages nerves outside the brain and spinal cord, is a possible complication. You might feel numbness, tingling, or a "pins and needles" sensation in your hands or feet. Weakness in your limbs can also occur, making daily tasks more challenging.

In some cases, the disease may cause hyperviscosity, where your blood becomes thicker than normal. This can reduce blood flow to your brain, leading to confusion, dizziness, or stroke-like symptoms. Rarely, you might develop soft tissue masses or solitary bone tumors (plasmacytomas), which can press on nearby nerves and worsen neurological issues.

Note: If you notice persistent neurological symptoms, consult a healthcare provider. Early intervention can help manage these complications effectively.

Development and Progression of Multiple Myeloma

Precursor Conditions

MGUS (Monoclonal Gammopathy of Undetermined Significance)

MGUS is a condition where abnormal plasma cells produce monoclonal proteins in your blood. While it doesn’t cause symptoms, it serves as an early warning sign for multiple myeloma. About 3% of Americans aged 50 and older have MGUS. In high-risk groups, such as Black individuals or those with a family history of blood cancer, this number can rise to 14% or even 42%. Routine screening for MGUS isn’t common, so it’s often discovered during tests for other conditions.

Smoldering myeloma

Smoldering myeloma represents a stage between MGUS and active multiple myeloma. Unlike MGUS, smoldering myeloma carries a higher risk of progression. You might not experience symptoms during this stage, but regular monitoring is crucial. Early detection of smoldering myeloma can help identify patients who may benefit from preventive treatments.

Disease Progression

Transition from smoldering myeloma to active multiple myeloma

The transition from smoldering myeloma to active multiple myeloma occurs when the disease begins to cause symptoms or organ damage. This progression often involves an increase in abnormal plasma cells or monoclonal proteins. If you have smoldering myeloma, your doctor may monitor you closely to detect any signs of progression early.

Factors influencing disease progression

Several factors can influence the progression of smoldering myeloma to active multiple myeloma. These include:

• Genetic mutations, which increase the risk of progression.

• A higher percentage of abnormal plasma cells in your bone marrow.

• Elevated levels of monoclonal proteins in your blood or urine.

Early intervention, especially for patients with genetic mutations, has shown promise in delaying or preventing the development of active multiple myeloma. Regular check-ups and advanced diagnostic tools can help you stay ahead of the disease.

Treatment Options for Multiple Myeloma

Standard Treatments

Chemotherapy and targeted therapy

Chemotherapy remains a cornerstone in treating multiple myeloma. It uses drugs like Doxil, Adriamycin, and Cytoxan to destroy cancerous plasma cells. These medications are often combined with other therapies to improve effectiveness. Targeted therapy, on the other hand, focuses on specific molecules involved in cancer growth. Monoclonal antibodies such as Darzalex and Empliciti enhance your immune system's ability to fight the disease. Steroids like dexamethasone are also commonly used to reduce inflammation and kill myeloma cells.

Here’s a table summarizing some effective treatments:

Stem cell transplantation

Stem cell transplantation (SCT) offers another effective treatment option. Autologous SCT, where your own stem cells are used, is the standard for patients under 65 or those who can tolerate the procedure. This approach, combined with high-dose chemotherapy, has shown a median survival of 68 months. Patients who undergo early transplantation often experience longer progression-free survival compared to those who delay the procedure.

• Median progression-free survival: 68 months (early transplantation) vs. 48 months (delayed).

• Overall survival rate: Approximately 85% after a median follow-up of 76 months.

Supportive Treatments

Medications for bone health

Multiple myeloma often weakens bones, making supportive treatments essential. Bisphosphonates like Zometa and Aredia help strengthen bones and reduce the risk of fractures. Denosumab (Xgeva), a monoclonal antibody, also works to prevent skeletal-related events. In some cases, surgery or radiation therapy may be necessary to treat damaged bones or spinal fractures.

• Common bone-supportive drugs:

  • Zometa (zoledronic acid)

  • Aredia (pamidronate)

  • Xgeva (denosumab)

Pain management and symptom relief

Managing pain is crucial for improving your quality of life. Pain medications, including over-the-counter and prescription options, can help alleviate discomfort caused by bone damage. Radiation therapy may also target specific areas of pain. For severe cases, surgical interventions like vertebroplasty can stabilize fractures and reduce pain.

Advancements in Care

Immunotherapy and CAR-T cell therapy

Immunotherapy has revolutionized the treatment of multiple myeloma. CAR-T cell therapy, which genetically modifies your immune cells to target cancer, has shown remarkable success. Recent FDA-approved therapies like Abecma and Carvykti target BCMA, a protein found on myeloma cells. Clinical trials are also exploring new CAR-T therapies aimed at GPRC5D, offering hope for patients with advanced disease.

Clinical trials and emerging treatments

Ongoing clinical trials continue to explore innovative therapies. New immunotherapies like Iberdomide and Cemsidomide are in development, targeting genetic mutations in myeloma cells. CAR-T therapies are also advancing, with a focus on combination treatments to improve outcomes. These emerging options aim to address unmet needs, particularly for high-risk patients or those with relapsed disease.

Prognosis for Multiple Myeloma Patients

Factors Affecting Prognosis

Stage of diagnosis

The stage at which you are diagnosed plays a critical role in determining your prognosis. Early-stage multiple myeloma often allows for more treatment options and better outcomes. Doctors use the Revised International Staging System (R-ISS) to evaluate the disease. This system considers biomarkers like beta-2-microglobulin and albumin levels, as well as genetic abnormalities. Early detection through effective diagnostic tools can help identify the disease before it progresses, giving you a better chance at managing it successfully.

Response to treatment

Your response to treatment significantly impacts your prognosis. Patients who respond well to therapies like chemotherapy, stem cell transplants, or immunotherapies often experience longer survival rates. Some individuals manage slow-growing forms of the disease for years, while others face more aggressive types. Advances in treatment have improved outcomes, but the variability in disease progression means that your response to therapy remains a key factor in determining your outlook.

Tip: Regular monitoring and follow-ups with your healthcare provider can help assess how well treatments are working and guide adjustments to your care plan.

Improvements in Survival Rates

Impact of new therapies

The introduction of innovative treatments has transformed the outlook for multiple myeloma patients. Therapies like CAR-T cell therapy and bispecific antibodies have significantly improved survival rates. These advancements have made achieving minimal residual disease (MRD)-negative outcomes more common, a milestone that was rare just a decade ago. Immunotherapies have also become essential in care, enhancing both longevity and quality of life. While high-risk patients still face challenges, new treatments offer hope for better outcomes and longer survival.

Importance of early detection

Catching multiple myeloma early can make a significant difference in your prognosis. Early identification allows you to access advanced treatments sooner, which can slow disease progression and improve survival rates. Diagnostic tools play a vital role in recognizing symptoms and confirming the disease. By addressing the condition early, you increase your chances of managing it effectively and maintaining a better quality of life.

Note: If you notice symptoms like persistent bone pain, fatigue, or frequent infections, consult a healthcare provider promptly. Early action can lead to better outcomes.
