Multiple Myeloma is a type of cancer that affects certain white blood cells called plasma cells. This condition contributes to an estimated 1% of all cancers in the United States, and about 22,000 Americans are diagnosed with this horrible disease every year. Multiple myeloma is also known as bone marrow cancer, which has already resulted in about 74,000 deaths globally in the year 2010.

Multiple-Myeloma Detailing multiple myeloma:

Multiple myeloma is a cancer of plasma cells, the white blood cell that’s present in your bone marrow and which constitutes an important part of the immune system. When these cells grow out of control, they produce a tumor called a plasmacytoma. The tumor generally developes in the bone and if someone has only a single plasma cell tumor, then the disease is said to be plasmacytoma and if someone has more than one plasmacytoma, then it’s called multiple myeloma. Basically, plasma cells are the antibodies that normally make proteins and help fight against infections.

In multiple myeloma, a group of plasma cells called as myeloma cells become cancerous. The cells start multiplying, which then raises its number to higher levels than normal. Some of the health problems associated with multiple myeloma may affect the bones of the spine, kidneys, skull, pelvis, immune system, and red blood cell count.

Symptoms of multiple myeloma:

Signs and symptoms of multiple myeloma may vary from person to person. During initial stages, myeloma may not cause any symptoms, but it is only diagnosed after a blood or urine test. As the disease progresses, it’s possible that you’ll experience at least one of the four major problems, which include:

  • High calcium level in your blood- This problem occurs when calcium from affected bones appears in your blood. Moreover, high calcium levels cause nausea, excessive thirst, constipation, loss of appetite and confusion.
  • Kidney failure– This condition happens when high levels of certain types of abnormal monoclonal proteins called as light chains or Bence Jones proteins increase in the blood.
  • Anemia-related fatigue- This condition occurs when myeloma cells replace oxygen-carrying red blood cells in your bone marrow.
  • Bone damage and fractures- Bone damage in multiple myeloma is referred to as osteolytic or lytic. Furthermore, bone pain particularly in your back, pelvis, ribs and skull is the common symptom.

Some of the other signs and symptoms of multiple myeloma include repeated infections like sinusitis, bladder or kidney infections, pneumonia, and skin infections. People with multiple myeloma may also experience weight loss or numbness in the legs.

Symptoms of multiple myeloma

Causes of multiple myeloma:

Multiple myeloma doesn’t have any specific causes. But, it can be caused by gene mutations that control how cells grow. People are more likely to get this cancer if they are male and 65 years or older, if they are from African-American descents or they are overweight or obese. Moreover, certain conditions also play a major role in causing multiple myeloma, these include the diseases MGUS (monoclonal gammopathy of uncertain significance) and solitary plasmacytoma, majorly affecting the plasma cells.

Diagnosing multiple myeloma:

After experiencing the above mentioned symptoms or signs, people have to visit their GP or doctor first. Then, their doctor will perform certain tests including blood and urine tests to diagnose the stage or condition of multiple myeloma as mentioned below:

Blood test:

There are many types of blood tests performed by the doctor to diagnose multiple myeloma. An erythrocyte sedimentation rate (ESR) blood test type shows whether there are unusual levels of proteins in your blood. A blood test is also conducted to measure the type and number of abnormal antibodies produced by the cancerous plasma cells. Moreover, doctor may also test your full blood count (FBC) to check the levels of different types of blood cells.
Other blood tests are performed to check the functioning of liver and kidneys. Furthermore, blood calcium level may also be checked because in myeloma, the calcium level can be high.

Urine tests:

This test is useful for diagnosing multiple myeloma. It indicates the number of abnormal proteins in the urine, that’s produced by the cancerous plasma cells. As abnormal proteins can damage your kidneys as they pass through them from the blood to the urine. Generally, this test is performed mainly to check the quantity of proteins being produced and how well the kidneys are functioning.

X-rays and other scans:

Abnormal growth of plasma cells produced in bone marrow can damage the outer layer of your bones. So, it is advisable that you should tell your specialist if you experience bone pain in certain parts of your body. After examination, your doctor will perform X-rays of the long bones, skull, spine and pelvis.
Scans like Computerized Tomography (CT) scans and Magnetic Resonance Imaging (MRI) may also be carried out to diagnose the condition.

Bone marrow test

This test is usually performed to confirm the diagnosis of multiple myeloma. Bone marrow test is performed by the doctor by using a needle to take a small sample of bone marrow (biopsy) from one of your bones, usually the pelvis. After taking the sample of bone marrow (and bone), it will be examined in a laboratory to check the presence of cancerous plasma cells.

How to treat multiple myeloma?

The process of treatment is very important,and requires a consultation by a team of healthcare experts and specialists in myeloma. These health care specialists will discuss your condition and recommends the best treatment. Additionally, if you’re experiencing symptoms, then the recommended treatment may somehow help relieve pain by controlling complications of the disease. Below are some of the treatment options of multiple myeloma:

Standard treatment

It is a fact that there is no cure for multiple myeloma, but you may prevent it with good treatment and also return to normal activity. Standard treatment includes drugs and therapies, which are mentioned below:

Medications:

  • Bortezomib This is the first approved drug for people who are recently diagnosed with myeloma. Bortezomib works by blocking the action of proteasomes and causes cancer cells to die.
  • Thalidomide- Thalidomide drug was reapproved by the Food and Drug Administration (FDA) in the year 1998. This drug is regarded as the first treatment for skin lesions caused by leprosy. But, today thalidomide is used for the treatment of multiple myeloma and is given orally.
  • Lenalidomide This drug is chemically similar to thalidomide and is currently used more than thalidomide. Lenalidomide medication is approved for people with previously treated myeloma, but is also used to treat people who have been recently diagnosed with the disease.
  • Corticosteroids Corticosteroids like Prednisone and Dexamethasone, have been used for decades to treat multiple myeloma. These medicines include steroid hormones that are given in pill form.

Therapies:

  • Chemotherapy- This therapy is commonly used for treating all types of cancer. Chemotherapy involves medicines, which are given to the patient orally as pills or given through an intravenous injection to kill myeloma cells. The session of chemotherapy involves various cycles, which are over a period of months, followed by a rest period. Some of the common chemotherapy drugs used to treat myeloma includes Cyclophosphamide, Melphalan, Vincristine, doxorubicin, and Liposomal Doxorubicin.
  • Stem cell transplantation- This process involves stem cells, which can be collected from a donor. Transplantation of stem cells involves chemotherapy, usually high doses of melphalan along with transfusion of previously collected stem cells to replace diseased or damaged marrow.
  • Radiation therapy- This therapy is done under the supervision of medical experts, which use high-energy penetrating waves to damage myeloma cells and stop their growth. Radiation therapy is used to shrink myeloma cells in a specific area.
