Frequently Asked Questions (FAQ) :
The survival rate for CML has significantly improved with advancements in targeted therapies. Many patients live for decades with proper treatment.
While targeted therapies can control CML effectively, a stem cell transplant offers a potential cure, particularly in younger patients.
The duration of treatment varies. Targeted therapy may be required indefinitely, while a stem cell transplant involves a more intense but shorter treatment period.
Yes, many patients with CML continue to live normal, active lives with proper treatment and regular monitoring.
Side effects vary depending on the treatment. Common side effects include fatigue, nausea, and increased susceptibility to infections, but these can often be managed with supportive care.
About Chronic Myelogenous Leukemia (CML)
Chronic Myelogenous Leukemia (CML) is a type of cancer that affects the bone marrow and blood, leading to the overproduction of abnormal white blood cells. Unlike acute leukemias, CML progresses slowly, which often allows for more effective management if detected early. The disease is primarily driven by a genetic mutation known as the Philadelphia chromosome, which creates an abnormal gene, BCR-ABL, responsible for the uncontrolled growth of white blood cells. Understanding CML is crucial for patients and their families as it allows them to make informed decisions about their treatment options.
Types of CML
CML is categorized into three distinct phases based on the progression of the disease:
- Chronic Phase: This is the initial stage where the disease progresses slowly. Patients may have mild or no symptoms, and the disease is often detected through routine blood tests. Treatment during this phase is highly effective, and most patients achieve long-term remission.
- Accelerated Phase: During this phase, the disease progresses more rapidly. Patients may start to experience more pronounced symptoms, such as fatigue, weight loss, and an enlarged spleen. Treatment needs to be more aggressive to control the disease at this stage.
- Blast Crisis Phase: This is the most advanced stage of CML, where the disease behaves similarly to acute leukemia. The number of immature white blood cells (blasts) increases significantly, leading to more severe symptoms and complications. This phase is challenging to treat and often requires a combination of therapies.
Causes of CML
The primary cause of CML is the formation of the Philadelphia chromosome, a result of a translocation between chromosomes 9 and 22. This genetic mutation is not inherited but rather occurs spontaneously. While the exact trigger for this mutation is unclear, exposure to high levels of radiation is a known risk factor. Other potential risk factors include aging, as CML is more common in older adults, and a family history of leukemia, although this is rare.
Symptoms of CML
- Fatigue and Weakness: Often due to anemia caused by a reduced number of healthy red blood cells.
- Unexplained Weight Loss: A significant drop in weight without any changes in diet or activity levels.
- Night Sweats and Fever: Excessive sweating at night and unexplained fevers are common.
- Pain or Fullness Below the Ribs: Typically caused by an enlarged spleen, leading to discomfort or a sense of fullness even after eating small amounts.
- Frequent Infections: A compromised immune system leads to frequent or severe infections.
- Easy Bruising or Bleeding: Low platelet counts cause bruising, nosebleeds, or gum bleeding.
- Bone or Joint Pain: Discomfort resulting from the spread of leukemia cells in the bone marrow.
Diagnosis of CML
Early diagnosis is key to managing CML effectively. Diagnosis typically involves a combination of:
- Blood Tests: To check for elevated white blood cell counts and other abnormalities.
- Bone Marrow Biopsy: A sample of bone marrow is taken to confirm the presence of the Philadelphia chromosome.
- Genetic Testing: Used to detect the BCR-ABL gene mutation, confirming the diagnosis of CML
Treatment Options for CML
Treatment for CML varies depending on the stage of the disease and the patient’s overall health. Dr. Rahul Bhargava, a renowned hematologist in India, offers comprehensive and personalized treatment options, including:
- Targeted Therapy: This is the frontline treatment for CML. Drugs such as Imatinib, Dasatinib, and Nilotinib target the BCR-ABL protein, inhibiting the growth of cancerous cells while sparing healthy ones. Most patients respond well to targeted therapy, achieving long-term remission.
- Chemotherapy: Used in more advanced stages, chemotherapy helps to reduce the number of leukemic cells and control the disease. It is often used in combination with other treatments.
- Stem Cell Transplant: For some patients, particularly younger individuals or those in advanced stages, a stem cell transplant (also known as a bone marrow transplant) may offer a potential cure. This procedure involves replacing the diseased bone marrow with healthy stem cells, restoring the body’s ability to produce normal blood cells.
- Clinical Trials: Patients may also have the opportunity to participate in clinical trials, gaining access to new and potentially more effective therapies that are not yet widely available.
