Chemotherapy is not a standard treatment for chronic myeloid leukemia (CML). If you get it, you meet with a medical oncologist before treatment starts. This doctor specializes in treating cancer with drugs. The doctor talks with you about your treatment and what you might expect.
Chemotherapy works by attacking and killing cells at different stages in their reproduction cycle. The drugs target cells that divide quickly, such as leukemia cells. Since the drugs also attack other rapidly dividing cells, chemotherapy may affect healthy cells, too. And that means you may have side effects.
Not everyone with CML takes the same drug or takes it the same way. Your treatment is individualized for you. The treatment the doctor prescribes is based on these factors:
The kind of leukemia you have
The phase of the leukemia
Your general health
Concerns you have about side effects
The way you have responded to treatment in the past
Your doctor's familiarity with certain protocols
For CML, the treatment your doctor prescribes is based on what phase you are in and may include chemotherapy or combinations of chemotherapy and other target drugs. Chemotherapies may be used during stem cell transplants and may be included in clinical trials. Some of the more commonly used chemotherapy drugs for CML include:
Synribo (omacetaxine mepesuccinate)
Other chemotherapy drugs might be used as well.
After evaluating your case, your doctor will decide these things:
The drug or a combination of drugs you'll take
How you will take the drugs
How long you should take them
Most people have chemotherapy as an outpatient at a hospital or clinic, at the doctor's office, or at home. Sometimes, though, depending on the drugs and on your health, you may need to stay in the hospital during treatment.
You may take chemotherapy in any of these ways:
Intravenous (IV) infusion into a vein
A combination of the above
Sometimes the drugs are injected directly into your spinal fluid to prevent cancer growth or to reach cancer cells that may hide there. This is called intrathecal chemotherapy or central nervous system (CNS) prophylaxis.
You receive chemotherapy in cycles over a period of time. That means you may take the drugs more than once, with periods of no drugs between treatment cycles. Having chemotherapy in cycles helps in many ways. It allows the drugs to kill more cancer cells because cells aren't all dividing at the same time. It allows your body to rest from the treatment, which damages quickly dividing normal cells, too, such as mucous membranes and bone marrow cells. It also gives you an emotional break between treatments. If your doctor doesn't tell you, you should ask how long this pattern will last. Knowing when it will end can make the routine easier to stay with.
Side effects of chemotherapy are different for everyone and vary based on the drugs you receive. The side effects usually end when the treatment ends. Ask your doctor or nurse which ones are most likely for you. Below is a list of common side effects that come with chemotherapy for CML:
Appetite loss, nausea, and vomiting
Bruising or bleeding from low blood platelets
Fatigue from low red blood cell counts
Infections from low white blood cell counts
The sensation of numbness or tingling, which can be painful, in the fingers or toes (called neuropathy)
These are some of the more serious potential side effects of CML chemotherapy:
Tumor lysis syndrome. This is caused by the breakdown of large numbers of leukemia cells. It can affect your kidneys, heart, and nervous system. Your doctor will check your kidney function and do other tests to watch for this.
Organ damage. This includes damage to kidneys, liver, testes, ovaries, brain, heart, or lungs
