What is multiple myeloma?

Multiple myeloma is a type of blood cancer of the bone marrow plasma cells. It affects the bones, blood, kidneys and immune system. The common sites you will experience pain are the spine skull, back, pelvis, rib cage and the area around shoulders and spine.

How common in multiple myeloma in Philippines?

As of 2020, the number of cases of multiple myeloma in Philippines were 766 with an incidence of 0.5% and a cumulative risk of 0.1%. The 5-year prevalence across all ages was 1.6 per 100,000.

Who is at risk for developing multiple myeloma?

Men are more likely to get affected by multiple myeloma than women. In addition, people of advanced age, those with a family history of multiple myeloma and with a greater chance of exposure to toxic chemicals or atomic radiation may get multiple myeloma?

Active types:

  • Solitary plasmocytoma – This is a single tumor usually in the bone. Normally treated with radiation and/or surgery.
  • Active multiple myeloma – Most aggressive form of the disease. It is clonal and can have many subtypes depending on the mutations present. A FISH analysis or genetic testing can help classify how aggressive your disease is.

How many types of multiple myeloma are there? What does it mean to have active multiple myeloma?

Multiple myeloma is not a single disease. It has inactive and active types. Among active multiple myeloma, we have less aggressive and more aggressive types.

Inactive types:

  • Monoclonal gammopathy of undetermined significance (MGUS) – Myeloma cells produce M protein but no symptoms yet.
  • Smoldering myeloma (SMM) – Myeloma cells make more M protein than MGUS and have a greater number of abnormal plasma cells. These levels are lower than in active multiple myeloma and the disease progresses slowly.

How do I make sense of my myeloma blood test?

Your doctor will order a complete blood count, blood chemistry to look for creatinine, calcium and albumin levels and a test called serum protein electrophoresis which looks for an abnormal protein called the M-protein. Look at the tables below to know if you are within normal ranges, if not you may be exhibiting some signs suggesting a multiple myeloma diagnosis.

Blood component Abbreviation Reference range
White blood cells WBC 4,500-11,000/millimeters cubed (mm3)
Red blood cellls RBC Male: 4.3-5.9 million/mm3
Female: 3.5-5.5 million/mm3
Platelets n/a 150-400 x 199/L
 
Test target Reference range
Creatinine

Age 18-16

Male: 0.9-1.3 milligrams per deciliter (mg/dL)
Female: 0.6-1.1 mg/dL

Age 60-90

Male: 0.8-1.3 mg/dL
Female: 0.6-1.2 mg/dL
Calcium 8.6-10.2 mg/dL
Albumin 3.5-5.5 grams per deciliter (mg/dL)

Is there a cure for multiple myeloma? What is my life expectancy?

Currently there is no cure for multiple myeloma. But many new drugs have been developed which have allowed more people to live longer than before. The 5-year survival statistics is 53.9%. This means nearly half of the people affected by multiple myeloma can live beyond 5 years with the current drugs in the market.

Is multiple myeloma hereditary? Should my family members also get tested?

Although the risk of multiple myeloma increases with a family history of the disease, it is not considered a genetic disease which runs in the family. Currently genetic testing is not performed in families to detect myeloma or its precursor conditions.

What is a bone marrow transplant?

Bone marrow transplant is a procedure where healthy stem cells either from your own body (autologous) or from a matched donor (allogeneic) are introduced into your body after destroying or cancerous bone marrow. This helps regenerate the blood cells in the bone marrow needed for proper functioning of your body.

Can I follow a normal lifestyle after receiving a bone marrow transplant?

Some aspects of your life will be restricted. For a period of time, you will need to be very careful to avoid getting any infections as the immune cells of your body were all destroyed during the procedure, and it can take a few weeks for the new healthy stem cells to make immune cells.

How do I know my treatment is working?

The doctor will do regular blood tests, urine tests and bone marrow biopsy and some times imaging tests (X-rays or CT scans) during the course of the disease and after each treatment cycle ends.

Can I receive complementary and alternative therapies?

Complementary treatments such as homeopathy, acupuncture, relaxation techniques, massage or Reiki can be helpful in relieving the symptoms caused by the disease or treatment. Discuss with your doctor about the alternative therapies you are considering and ensure they will not interfere with the specific treatments planned by your doctor.
