How long can you live with multiple myeloma without treatment?

Multiple myeloma is a rare cancer affecting specific white blood cells, originating in the bone marrow. Understanding its progression without intervention is a serious concern, as individual experiences vary significantly. This article explores the disease’s nature, factors influencing its course when left untreated, and potential health consequences.

Understanding Multiple Myeloma’s Nature

Multiple myeloma begins with plasma cells, white blood cells that normally create antibodies. In this condition, healthy plasma cells transform into cancerous myeloma cells that multiply excessively within the bone marrow. This accumulation of abnormal cells can crowd out healthy blood-forming cells. Instead of producing effective antibodies, these cancerous cells generate abnormal proteins, called M-proteins, which do not function correctly.

As myeloma cells proliferate, they can disrupt normal bodily functions and damage various organ systems. The presence of M-proteins can also lead to complications by interfering with the body’s natural processes. This uncontrolled growth and dysfunctional protein production drive disease progression.

Key Factors Affecting Survival Without Treatment

Predicting an exact survival timeframe without multiple myeloma treatment is not possible, as each individual’s disease is unique. Several factors influence how the condition progresses without therapy. One factor is the disease stage at diagnosis, often assessed using systems like the International Staging System (ISS) or the Revised International Staging System (R-ISS). The R-ISS incorporates levels of serum beta-2 microglobulin, serum albumin, lactate dehydrogenase (LDH), and specific chromosomal abnormalities for a more precise prognosis.

Genetic characteristics of myeloma cells, known as cytogenetic abnormalities, also play a substantial role. Certain abnormalities, such as deletion 17p, translocation t(4;14), and translocation t(14;16), indicate a more aggressive disease form. These high-risk features suggest a faster progression. The patient’s general health and age at diagnosis are additional considerations, as existing medical conditions can affect the body’s ability to cope with disease advancement. The disease’s progression rate, varying from indolent to aggressive, also influences the timeline without treatment.

Health Consequences of Untreated Multiple Myeloma

Leaving multiple myeloma untreated allows the disease to advance, leading to severe health problems. One common complication is significant bone damage, as myeloma cells can form masses in the bone marrow and increase the activity of cells that break down bone. This results in weakened bones, causing pain, increased fracture risk, and elevated blood calcium levels (hypercalcemia). Hypercalcemia can cause confusion, fatigue, muscle weakness, and affect kidney and heart function.

Kidney function often deteriorates in untreated multiple myeloma due to abnormal M-protein accumulation. These proteins can damage the kidneys, potentially leading to kidney failure. Myeloma cell crowding in the bone marrow also impairs healthy red blood cell production, resulting in anemia. Anemia causes persistent fatigue, weakness, and shortness of breath, profoundly impacting daily life.

The immune system is compromised in multiple myeloma, making individuals more susceptible to infections. Myeloma cells produce dysfunctional antibodies and can reduce healthy white blood cells, weakening the body’s ability to fight bacteria and viruses. Infections are a leading cause of early death in individuals with multiple myeloma. The disease can also lead to neurological issues, including nerve compression or spinal cord problems, often caused by bone fractures or tumors pressing on nerves.

Navigating Treatment Decisions and Support

Making decisions about multiple myeloma care involves careful consideration. Consulting with a hematologist-oncologist is an important step. These specialists provide a thorough, personalized assessment of the disease and discuss all available treatment options. While this article addresses living without treatment, medical guidance is essential for managing the condition.

Palliative care offers support for symptom management and improving comfort, regardless of whether active treatment is pursued. Palliative care teams work alongside other doctors to address pain, fatigue, and other challenges, providing support for patients and their families. The decision regarding a course of action is deeply personal and best made with comprehensive medical advice and support.
