What is a relapse in multiple myeloma?

Although treatment can reduce the number of myeloma cells in the body, there may be cells that remain or become resistant to treatment. Over time, these cells may start to multiply. After a period of improvement following treatment, multiple myeloma will return for most people, which is known as a relapse. A relapse may mean that you and your healthcare provider should consider a new treatment.

How often can multiple myeloma relapse?

Almost all people with multiple myeloma will experience a relapse and some may experience several relapses over time. If you have multiple myeloma, it is likely it will come back, even after successful treatment. When multiple myeloma relapses, lab tests will show increasing levels of an abnormal antibody called M protein.

A multiple myeloma relapse can occur with or without symptoms  

When multiple myeloma returns, the experience can be different for every person. Some people have symptoms when multiple myeloma relapses, while others may not. Some people only learn that a treatment change may be needed because of certain changes in lab results, such as increasing levels of M protein. 

When multiple myeloma relapses, you may hear different terms used to describe the relapse: 

Progressive disease: Multiple myeloma that has progressed as measured by serum or urine laboratory tests or by imaging studies.  

Refractory disease: When multiple myeloma doesn’t initially respond or stops responding to a certain treatment, it is known as refractory multiple myeloma. This is also known as treatment resistance.  

Primary refractory disease: Multiple myeloma that does not respond to initial treatment.

Talk to your healthcare provider about your M proteins levels and how you're feeling—be sure to communicate any changes, even small ones. Symptoms can be subtle at 
first and it can be hard to know if symptoms are related to your multiple myeloma relapsing or another condition. 

What are the signs that my multiple myeloma has relapsed? 

Flip the cards over to learn about the types of multiple myeloma relapses.

LIMITED OR NO SYMPTOMS AND INCREASING M PROTEIN LEVELS
(Also called an M spike) 

This type of relapse is called an indolent relapse or biochemical relapse 

INDOLENT RELAPSES HAVE LIMITED OR NO SYMPTOMS

  • No obvious multiple myeloma symptoms (mild symptoms may not be noticeable)
  • No organ problems
  • M spike identified on lab tests

SYMPTOMS AND INCREASING M PROTEIN LEVELS
(Also called an M spike)

This type of relapse is known as a symptomatic relapse or clinical relapse  

SYMPTOMATIC RELAPSES HAVE OBVIOUS SYMPTOMS

  • Multiple myelom a symptoms such as fatigue, shortness of breath, or bone pain
  • Symptoms may range from mild to severe and may change over time
  • Organ problems may occur (such as kidney problems)

Tracking M protein is a way of monitoring your multiple myeloma

Lab tests can help monitor your multiple myeloma and signal the first sign of a relapse 

An increase of M protein in your blood is a sign that your multiple myeloma may have relapsed. The amount of M protein is measured using a multiple myeloma test, the M spike lab test. It is called an M spike when M protein is detected in your blood or urine. Some people have myeloma cells that produce very little M protein, whereas others produce a lot of M protein, so it’s important to track your M protein levels individually over time.

Treatment options for relapsed multiple myeloma

There are many options for treating relapsed multiple myeloma. Several factors can help determine the next treatment that’s right for you including which prior treatments you’ve had and how long your multiple myeloma responded to those treatments.

Treatment options for relapsed multiple myeloma include chemotherapy, targeted therapies like proteasome inhibitors, monoclonal antibodies, hematopoietic stem cell transplantation (HSCT) (only for eligible patients who did not receive HSCT as part of their initial treatment), or a clinical trial. These therapies may be given in combination.

Early treatment can make a difference 

In a study of patients experiencing a first multiple myeloma relapse, early treatment resulted in better outcomes for patients whose M protein levels were increasing and who weren’t experiencing any symptoms. Even before your multiple myeloma relapses, you can start working with your doctor to determine the next treatment that's right for you. The path a treatment journey takes will be different for every person, but you are not alone. There are resources and support groups that can help.
