Treatment Options for Chronic Myelogenous (Myeloid) Leukemia (CML)
Chronic Myelogenous Leukemia (CML) is a type of blood and bone marrow disease characterized by the overproduction of white blood cells. The objective of treatment for CML may be dependent on the phase of the disease. Here are the objectives of treatment for each phase of CML:
Chronic Phase: This phase of CML is an early, slower growing phase. Leukemia cells (blasts, or the immature white blood cells) comprise < 10% of the cells in the blood and bone marrow.
- The main goal of treatment is to try to cure the disease or prolong the chronic phase.
- Treatment aims to help patients lead a normal life as much as possible.
Accelerated Phase: This is a transitional phase where the CML starts to become more aggressive. Blasts comprise between 10% to 20% of the blood and bone marrow.
- Treatment aims to slow down the progression of the disease and prevent it from transforming into blastic phase.
Blastic Phase: This is a severe, very aggressive phase. Blasts comprise 20% or more of cells in the bone marrow and blood. A blast crisis is when the blast phase is accompanied by fatigue, fever and an enlarged spleen. A blast crisis may be life-threatening
- Treatment aims to control symptoms and improve quality of life.
In summary, depending on the phase of the disease, treatment can aim to cure the disease, slow down its progression, prolong the chronic phase, control symptoms, or improve quality of life.
Treatment options for CML may vary depending on the phase of the disease. CML has three phases: chronic, accelerated, and blastic. Let's take a look at the treatments for each phase:
Chronic Phase CML:
- Targeted therapy with a tyrosine kinase inhibitor (TKIs): TKIs are drugs that target specific cancer cells and inhibit their growth. They act by blocking proteins that drive the growth of cancer cells. People with CML that responds to TKIs may need to take them for the rest of their lives.
- High-dose chemotherapy with donor stem cell transplant: In some cases, high-dose chemotherapy may be recommended along with a stem cell transplant from a donor. This procedure aims to replace the unhealthy stem cells in the bone marrow with healthy ones. High dose chemotherapy is first used to kill all blood-forming cells in a person’s bone marrow. Then, stem cells from a donor are infused. These stem cells can then develop into health blood cells in the recipient.
- Chemotherapy: Chemotherapy involves the use of medications to kill cancer cells. It can be used as a standalone treatment or in combination with other therapies, such as targeted therapies.
- Splenectomy: In some cases, surgical removal of the spleen (splenectomy) may be recommended to relieve symptoms or improve quality of life.
- Clinical trials: Participating in clinical trials of lower-dose chemotherapy or new treatments is another option. Clinical trials help researchers test new therapies and determine their effectiveness.
Accelerated Phase CML:
- Donor stem cell transplant: Stem cell transplant from a donor may be recommended as a treatment option for accelerated phase CML.
- Targeted therapy with a tyrosine kinase inhibitor.
- Tyrosine kinase inhibitor therapy followed by a donor stem cell transplant: This approach involves using targeted therapy first, followed by a stem cell transplant.
- Immunotherapy: These treatments boost the body’s immune system to fight the cancer. They may help slow tumor growth. An example of an immunotherapy use in CML is interferon.
- Chemotherapy, including high dose chemotherapy.
Blastic Phase CML:
- Targeted therapy with a tyrosine kinase inhibitor (TKI).
- High-dose chemotherapy.
- Donor stem cell transplant.
- Chemotherapy as palliative therapy: In some cases, chemotherapy may be used as palliative therapy to relieve symptoms and improve quality of life.
Across all phases, clinical trials may be available. Clinical trials may provide access to new treatments. It is important to discuss your specific situation with the healthcare team to see if a clinical trial is a recommended potential option.
It's important to note that these are potential treatments for CML, but the specific treatment plan should be discussed with a healthcare professional. They will consider factors such as the phase of the disease, individual health status, and potential side effects before recommending an appropriate treatment approach.
As for lifestyle changes, there is no specific evidence suggesting that they directly impact the treatment of CML. However, maintaining a healthy lifestyle can support overall well-being during treatment.
Remember to consult with your healthcare provider before considering any home remedies or over-the-counter medications for treating CML. They will provide personalized advice based on your specific situation.
