Chemotherapy is sometimes used to treat multiple myeloma, although this is less common due to newer treatments. When it is used, it’s often in combination with other drugs.
Chemotherapy, often referred to as chemo, may be used to treat multiple myeloma (MM). However, chemo for MM has become less common due to the emergence of newer treatments.
Below, we go deeper into the goals of chemo treatment for MM, the specific chemo drugs used, and the types of side effects to be aware of.
The goal of chemotherapy for MM is to slow or stop the growth of the cancer. Depending on where you are in your MM journey, this can help prepare you for the next phase of your treatment or can work to keep your cancer in remission.
Chemo may still be used in some phases of MM treatment. The phases of MM treatment are:
- Induction: Induction is the initial part of your MM treatment. Its goal is to reduce the amount of cancer in your body. This may or may not include chemo, often alongside other drugs used to treat MM.
- Consolidation: Consolidation is a short course of chemo or other drugs sometimes given after a stem cell transplant, one of the main treatments for MM. It helps eliminate any remaining cancer cells.
- Maintenance: Maintenance works to help keep your MM in remission. Chemo isn’t typically used in this phase. Instead, maintenance typically involves immunomodulating drugs or targeted therapy drugs.
Several chemo drugs may be used to treat MM. These include:
The types of treatment that are planned affect which chemo drugs may be used. Some chemo drugs, such as melphalan, can damage the bone marrow. As such, these types of chemo drugs may not be used for people who are having a stem cell transplant.
Chemo for MM is often combined with other types of treatment, such as:
- targeted therapy
An example of such a combination is bortezomib, cyclophosphamide, and dexamethasone.
Chemo drugs can also impact healthy, quick growing cells in the body. Because of this, chemo is associated with a variety of side effects.
Some common short-term side effects of chemo include:
- low blood cells counts, which can lead to:
- an increased infection risk
- bruising or bleeding easily
- hair loss
- reduced appetite
- throat and mouth sores
- nausea and vomiting
- mouth sores
These side effects typically go away after you stop chemo. However, there are also some side effects of chemo that can show up months or years later. These are called late effects and may include:
The outlook for people who receive chemo for MM can depend on many factors. These include:
- the extent and characteristics of your MM
- the type of chemo drugs used
- the other types of MM treatment used with or after chemo
- how your MM responds to your treatment plan
- whether you’re being treated for a cancer relapse
- your age and overall health
According to the National Cancer Institute, the relative 5-year survival rate for MM is
When we discuss cancer outlook, know that outlook statistics don’t take individual factors into account. They also may not reflect recent advances in treatment.
There are potential alternative drug combinations used to treat MM that do not include chemo. These typically include combinations of the following drug types:
- targeted therapy drugs, such as:
- immunomodulating drugs, such as lenalidomide (Revlimid) and thalidomide (Thalomid)
- corticosteroids, such as dexamethasone
One example of a
If a stem cell transplant is recommended as a part of your treatment, you will likely receive high dose chemo as a part of that procedure. However, in some situations, radiation
Lastly, if other MM treatments haven’t been effective, another potential treatment option is CAR T-cell therapy. This is a type of immunotherapy that modifies immune cells collected from your blood so they attack cancer cells.
Can pregnant people get chemotherapy for multiple myeloma?
Can I breastfeed during chemotherapy for multiple myeloma?
No. Some chemo drugs may be present in breast milk. This means they may be passed to your baby when you breastfeed.
Talk with your care team about when it’s safe to resume nursing after your chemo treatment has concluded.
Can I get vaccines while I’m having chemotherapy for multiple myeloma?
Yes, you can get some vaccines while you’re undergoing chemo. Because chemo weakens your immune system, these vaccines can help protect you from potentially serious illnesses.
Can multiple myeloma come back after chemotherapy?
Having a relapse early after your initial treatment is associated with poorer outcomes. A
Chemo is sometimes a part of MM treatment. However, its use for MM outside of a stem cell transplant is becoming less common due to newer treatments. When it is used, chemo is typically given in combination with other types of drugs.
Chemo drugs can lead to both short- and long-term side effects. If chemo is recommended as a part of your MM treatment, be sure to discuss its various risks and benefits with your care team beforehand.
