What is M spike in multiple myeloma?
Apr 02, 2016 · Just to give you an idea of some round numbers, I recall that M Spike going to zero (also referred to as complete response), is something like 30% based on induction drugs, only. This number I believe is a typical number for RVD, which is the standard of care in the US. M spike going down by 90% is called Very Good Partial Response (VGPR).
What does the M spike mean on protein electrophoresis?
Feb 10, 2011 · The M-spike percentage is the percentage of the total protein that is made up of the M spike. Your total protein must be about 6.82 g/dL – because 13.04% of 6.82 g/dL is 0.89 g/dL. I think it’s just another way to follow the magnitude of the spike – though I think the size of the spike itself (the 0.89 g/dL) is probably a more direct and ...
What is the normal range for M-protein and M-spike levels?
I am a caucasian female. My m-spike at diagnosis was .3. I was diagnosed incidentally by a hematologist that I saw for fatigue. Four years later my m-spike is .5. I am IgG lambda. No other symptoms. Free Light Chain ratio is normal. I live my life in fear of progression to full-blown multiple myeloma and it is really taking a toll on me.
Can M spike decrease?
Impact of M-spike response on median overall survival Ninety-two (63%) patients achieved at least a 50% reduction in the initial M spike after 4 months of therapy.
Can M spike fluctuate?
The M-spike usually remains stable with small fluctuations in its concentration, until MM develops. Patients are at higher risk for developing venous thromboembolism, osteoporosis, and fractures, even in the absence of progression to MM.
Does multiple myeloma go away by itself?

What is considered a high M protein level?
High levels mean the disease is more advanced and may indicate a poor prognosis. The presence of any M spike is abnormal and shows the presence of an abnormal clone of plasma cells. If the amount of protein is ≥30 g/L and/or there are other disease symptoms, the patient may have myeloma.
What is the normal range for M spike?
Normal range: 0.57-2.63 mg/dL Multiple myeloma or another plasma cell disorder may be indicated by increased lambda free light chains and a decreased kappa/ lambda ratio.
How long can you live with monoclonal gammopathy?
Data from the Mayo Clinic showed that the median survival of MGUS patients was 8.1 years compared to 11.8 in the comparable US population.
How to check for M protein?
If your doctor finds M proteins in your blood, they may run further tests to rule out any conditions related to MGUS that could cause problems. These tests may include: 1 A complete blood count (CBC). This blood test measures the levels of different cells in your blood and can reveal certain MGUS-related issues such as anemia. 2 Beta-2 microglobulin test. Abnormal plasma cells may also create a type of protein called beta-2 microglobulin. High levels of this protein suggest a more advanced state of MGUS-related disease such as multiple myeloma. 3 Biopsies. These tests involve removing and then analyzing a small amount of tissue from your bone marrow, a tumor, or lymph nodes. 4 Blood chemistry tests. These tests measure creatinine, albumin, calcium, and lactic dehydrogenase (LDH). Abnormal levels of these substances may indicate complications from MGUS and a worse outlook. 5 Echocardiogram (ECHO). This test is used to check for any heart problems, as these are one possible complication from amyloidosis. Amyloidosis can be caused by MGUS. 6 Imaging tests. MRIs, CT scans, PET scans, and X-rays are used to determine how far cancer has spread or to check bones for damage from multiple myeloma. 7 #N#Urine protein tests. Urine protein electrophoresis (UPEP) and urine immunofixation tests measure levels of M proteins produced by your body over a 24-hour period.
How does multiple myeloma affect blood?
When multiple myeloma affects plasma cells, they begin to grow out of control and fill the bone marrow and blood with large amounts of M proteins . These cancerous plasma cells begin to outnumber healthy blood-forming cells in the bone marrow. When M proteins begin to outnumber normal blood cells, this can result in a low blood count ...
What is the name of the protein that is found in the blood?
Other common names for these proteins include: monoclonal immunoglobulin. M- spike. paraprotein. Finding M proteins in the blood or urine is usually a sign of disease. Their presence is associated most commonly with a type of cancer of the plasma cells called multiple myeloma.
What is the protein in bone marrow?
Your bone marrow is a soft tissue found inside most of your bones that produces blood cells. Sometimes, the plasma cells create abnormal proteins. These abnormal proteins are called M proteins, or monoclonal proteins. Other common names for these proteins include: monoclonal immunoglobulin. M-spike. paraprotein.
How does immunoelectrophoresis work?
It involves placing a sample of the liquid part of your blood (called serum) into a gel that’s exposed to an electric current. The current induces the different proteins in your serum to move and group together . The next step is to use immunoelectrophoresis to determine the exact type of proteins in the blood.
What is a complete blood count?
A complete blood count (CBC). This blood test measures the levels of different cells in your blood and can reveal certain MGUS-related issues such as anemia. Beta-2 microglobulin test. Abnormal plasma cells may also create a type of protein called beta-2 microglobulin.
Where are proteins found in the body?
Proteins are an important component of all living organisms. They can be found in all types of body tissues, including the blood. Antibodies are one example. These protective proteins attack and kill off invading disease (s).
What is the spike in myeloma?
In myeloma, the immunoglobulin is monoclonal, so it all migrates to exactly the same spot on the gel! Which gives you a big spike (if you’re looking at a tracing) or a very distinct, crisp, strong band (if you’re looking at the gel itself). This spike is called an M-spike (you could remember M for either monoclonal or myeloma), ...
What is the M protein?
This spike is called an M-spike (you could remember M for either monoclonal or myeloma), and the corresponding monoclonal protein that it represents is called an M protein. A few other things to note about this M protein: 1. You need to do electrophoresis on urine too, not just serum.
Where does multiple myeloma originate?
A. Multiple myeloma is a malignant, clonal disorder of plasma cells that originates in the bone marrow. It’s a relatively common disorder, accounting for 1% of all malignancies and 10% of all hematologic malignancies in adults.
What is the most abundant protein in the blood?
There’s a predictable pattern of proteins in normal serum: albumin (the most abundant protein in the blood) migrates to a certain predictable point; other proteins migrate to different places (which are given different names – the alpha 1 region, the alpha 2 region and the beta region).
What is a MM?
“Multiple myeloma (MM) evolves through a spectrum of disease from a premalignant stage of monoclonal gammopathy of undetermined significance (MGUS) (serum M-protein value of <30 g/L, bone marrow plasma cells <10%, no or small amount of M-protein in the urine, and absence of lytic bone lesions, anemia, hypercalcemia, or renal insufficiency) to an intermediate stage of smoldering multiple myeloma (SMM) (serum M protein level >30 g/L and/or bone marrow plasma cells >10%, plus no anaemia, hypercalcemia, renal failure, or lytic bone lesions) and finally presents with symptoms and signs of end-organ damage which leads to the diagnosis of MM [1]. Studies indicate that almost all cases of MM are preceded by the precursor state of MGUS or SMM [2]…
What are the benefits of eating healthy for cancer patients?

What is the stage of myeloma between MGUS and active myeloma?
The stage of myeloma between MGUS and active myeloma is called smoldering multiple myeloma (SMM), which is characterized by a higher level of M-protein than MGUS but with no indicators of active myeloma.
Where does myeloma grow?
A malignant plasma cell is called a myeloma cell. Myeloma most often grows in the marrow within the bones of the spine, skull, pelvis, rib cage, shoulders, and hips. Usually, the bones of the hands, feet, and lower parts of the arms and legs are not affected, preserving the function of these critical areas.
Is MGUS a cancer?
MGUS, SMM, and active myeloma: The earliest stage of myeloma is not cancer at all, but is a benign condition called MGUS, the presence of a low level of monoclonal protein (M-protein) without any indicators of active myeloma.
What does M protein mean?
M-protein is an antibody—or part of an antibody—that can show up in tests of your blood and/or urine, and its presence can mean different things. In blood cancers such as myeloma, the 'M' in 'M protein' stands for monoclonal. A monoclonal protein is produced by the abnormal, cancerous or precancerous cells.
What is MGUS in cancer?
MGUS - Monoclonal gammopathy of undetermined significance may have an elevated level. Waldenstrom's macroglobulinemia - This cancer, which involves cells which are precursors of plasma cells, may have an elevated M protein level.
How many parts are in an antibody?
Each antibody is made up of four parts. There are two long chains on the inside, and two shorter chains on the outside. In the image, you can see a plasma cell with an antibody and many other tiny antibodies in the background.
Can M protein cause cancer?
Many conditions can cause a monoclonal gammopathy, a spike in one protein product; and, not all of these conditions are cancerous. You can have M protein with certain connective tissue disorders, like systemic lupus erythematosus, rheumatoid arthritis, and psoriatic arthritis. You can have it with Hepatitis C virus infection and HIV/AIDS. You can even have it with acquired von Willebrand disease, a rare bleeding disorder. Thus, in many instances, the cause of the M protein is more important than the mere presence of this finding.
Do plasma cells produce antibodies?
Ordinarily, plasma cells will produce a wide range of antibodies. In the normal or healthy state, the population of plasma cells capable of producing a wide array of different antibodies—so-called polyclonal antibodies, or polyclonal immunoglobulins.
