Is the M spike a reliable marker of disease transformation?
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).

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 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.
Is myeloma a cancer?
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. People with MGUS are monitored carefully to make sure the diagnosis is correct and there is no change in their status.
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?
A healthy diet, such as the one Kennedy describes, can provide a range of benefits for cancer patients, potentially by helping to reduce inflammation and manage common side effects of treatment, such as constipation and fatigue.
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 ...
Where are antibodies found?
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). When you’re healthy, plasma cells (a type of white blood cell) in your body’s bone marrow help your body fight infections by producing antibodies that find and attack germs.
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 MGUS in blood?
MGUS is a condition caused by abnormal changes in plasma cells, which are part of the immune system. Because it does not usually cause any symptoms and there is no standard screening, almost all cases of MGUS are discovered incidentally through blood tests for another condition or concern, explained Dr. Landgren, a former NCI investigator.
What is a light chain MGUS?
Light-chain MGUS, which can develop into light-chain multiple myeloma, differs from MGUS in the type of protein made by the abnormal plasma cells. When they looked at how individuals’ risk scores changed over time, they noticed some interesting patterns. For example, about half of those who progressed to multiple myeloma—but only one person who ...
What is Waldenstrom's macroglobulinemia?
Waldenstrom's macroglobulinemia - This cancer, which involves cells which are precursors of plasma cells, may have an elevated M protein level. In some cases, cells causing the M-protein are malignant, and they may invade the bone, lymph nodes, liver, spleen, or other organs. This is the case in multiple myeloma, solitary plasmacytoma, ...
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.
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.
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.
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.
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.
