Multiple myeloma is a type of cancer that affects plasma cells in the bone marrow, and it primarily occurs in older adults, typically between the ages of 40 and 70, with risk increasing as people age. Understanding the warning signs of multiple myeloma progression in older adults is crucial because early detection of disease advancement can significantly influence treatment decisions and quality of life.
The progression of multiple myeloma often manifests through a variety of symptoms and clinical signs that reflect the disease’s impact on the bones, blood, kidneys, and overall immune function. These warning signs can be subtle at first but tend to worsen as the disease advances.
**Bone Pain and Fractures**
One of the most common and earliest warning signs of multiple myeloma progression is persistent bone pain. This pain is often localized in the back, chest, ribs, pelvis, or upper legs. It occurs because myeloma cells cause increased bone breakdown, weakening the bones and making them prone to fractures. Older adults may notice new or worsening pain that does not improve with usual treatments. Pathological fractures—breaks caused by weakened bones rather than trauma—are a serious sign of progression.
**Fatigue and Weakness**
Fatigue is a frequent symptom in multiple myeloma and tends to worsen as the disease progresses. This fatigue is often related to anemia, a condition where the number of red blood cells is reduced because the bone marrow is crowded with cancerous plasma cells, impairing normal blood cell production. Older adults may feel unusually tired, weak, or short of breath even with minimal exertion.
**Frequent Infections**
As multiple myeloma progresses, the immune system becomes compromised. The abnormal plasma cells produce ineffective antibodies, reducing the body’s ability to fight infections. Older adults might experience recurrent infections such as pneumonia, urinary tract infections, or skin infections. These infections can be more severe and harder to treat, signaling a decline in immune function.
**Elevated Calcium Levels (Hypercalcemia)**
Bone destruction releases calcium into the bloodstream, leading to hypercalcemia. Symptoms of high calcium include increased thirst, frequent urination, dehydration, constipation, nausea, confusion, and in severe cases, coma. These symptoms in an older adult with known multiple myeloma should raise concern for disease progression.
**Kidney Dysfunction**
Multiple myeloma can cause kidney damage due to the accumulation of abnormal proteins produced by myeloma cells. Warning signs of kidney involvement include swelling in the legs or ankles, decreased urine output, fatigue, and confusion. Blood tests may reveal elevated creatinine or other markers of kidney impairment.
**Neurological Symptoms**
In some cases, myeloma progression leads to nerve damage. This can cause numbness, tingling, or weakness in the hands or feet (peripheral neuropathy). Compression of the spinal cord by bone lesions may cause back pain, difficulty walking, or loss of bladder and bowel control, which are medical emergencies.
**Weight Loss and Loss of Appetite**
Unintentional weight loss and decreased appetite are common in advancing cancer, including multiple myeloma. These symptoms may reflect systemic disease progression and overall decline in health.
**Laboratory and Imaging Changes**
Progression is also detected through laboratory tests showing increasing levels of abnormal proteins (M protein) in the blood or urine, rising beta-2 microglobulin levels, and worsening anemia or low platelet counts. Imaging studies such as X-rays, MRIs, or CT scans may reveal new or expanding bone lesions or fractures.
**Additional Considerations in Older Adults**
Older adults often have other chronic health conditions that can complicate the recognition of myeloma progression. Symptoms like fatigue or weakness may be mistakenly attributed to aging or other illnesses. Moreover, older patients may have reduced organ function, affecting how their body handles treatments and disease symptoms. Physical frailty can make coping with progression more difficult.
