What are the key tests that should take place following a multiple myeloma diagnosis? Dr. Peter Forsberg details the appropriate tests, including imaging and blood tests, that may aid in assessing the risk and informing treatment options.

Dr. Peter Forsberg is assistant professor of medicine at the University of Colorado School of Medicine and is a specialist in multiple myeloma. More about Dr. Forsberg here.

What testing should take place following a myeloma diagnosis?

Dr. Forsberg:             

So, after a patient is diagnosed with myeloma, or with suspected myeloma, a number of tests take place to both understand the myeloma. Get some sense for how aggressive the myeloma might be and understand what may be being caused by the myeloma at any given time. So, that involves a number of blood tests. It involves checking urine, doing at least one 24-hour collection of urine. Doing imaging, tests to look at the skeleton or different areas of the body for myeloma involvement.

And a bone marrow biopsy and what’s called an aspirate.

So, all those tests together are used to help confirm myeloma, to understand what’s going on with it and then to understand some of the characteristics of it that might be important over time.

Some of the more complicated tests when people are initially diagnosed with myeloma to get their head around are some pretty important blood tests that we monitor pretty closely.

Things called the serum protein electrophoresis and serum light chain assays. And basically, those are tools that help us measure antibodies. Myeloma is a disease; it comes from cells that make antibodies or fragments of antibodies. And by measuring those, we can understand the myeloma, we can give it some names. And then we can also measure it over time. So, those can seem a little bit impenetrable to patients when they’re first diagnosed, but they’re pretty important for patients and for people treating the myeloma to understand where the myeloma stands and how things are going.


What about genetic testing?

Dr. Forsberg:             

So, the main way that we use genetic testing in multiple myeloma is through something called, cytogenetics. And cytogenetics is a way for us to evaluate chromosomes. Chromosomes are in cells and that’s where genetic material is contained. And in myeloma, some of the main vents that drive myeloma cells to change from normal plasma cells come through changes in chromosomes.

And so, those chromosome changes that can be detected with different tests, sometimes they’re called karyotyping or what’s called FISH can give us a sense for some of the changes that may drive the myeloma or have driven it in the first place.
