Acute Myelomonocytic Leukemia - Symptoms, Reasons and Treatment

Acute Myelomonocytic Leukemia is a type of blood cancer that affects the bone marrow and blood cells. In this condition, there is an abnormal increase in myelomonocytic cells, which are a type of white blood cell. The exact cause of Acute Myelomonocytic Leukemia is not fully understood, but it is believed to result from genetic mutations that cause the bone marrow cells to grow and divide uncontrollably. 

These mutations can prevent normal blood cell production and lead to the accumulation of immature and abnormal cells in the blood. While the specific triggers for these genetic mutations are not clear, factors such as exposure to certain chemicals, radiation, or a history of certain genetic disorders.

Symptoms of Acute Myelomonocytic Leukemia

Acute Myelomonocytic Leukemia can cause various symptoms that may include fatigue, weakness, pale skin, easy bruising or bleeding, frequent infections, fever, night sweats, and unintentional weight loss. Some individuals may also experience bone pain, shortness of breath, swollen lymph nodes, and an enlarged spleen. It is important to consult a healthcare provider if experiencing these symptoms, as early detection and treatment are crucial for managing the condition effectively.

Causes of Acute Myelomonocytic Leukemia

While the exact cause of AMML is not fully understood, certain risk factors have been identified, including exposure to ionizing radiation, certain chemicals (like benzene), previous chemotherapy or radiation therapy for other cancers, and genetic predisposition.Early detection and prompt treatment are crucial in managing this aggressive form of leukemia.

Types Of Acute Myelomonocytic Leukemia

These subtypes include AMML with myelodysplasia-related changes (AML-MRC), AMML with eosinophilia (AML-eo), and AMML with inv(16)(p13. 1q22) or t(16;16)(p13. 1;q22) resulting in abnormal CBFB-MYH11 gene fusion. Each subtype may have distinct clinical features and treatment responses, guiding healthcare providers in tailoring appropriate management strategies for patients with AMML.

Risk Factors

Several risk factors have been identified for AMML, including exposure to certain chemicals like benzene, prior chemotherapy or radiation therapy, genetic disorders such as Down syndrome, and a history of certain blood disorders or bone marrow diseases. Understanding these risk factors can help in early detection and management of the disease.

Diagnosis of Acute Myelomonocytic Leukemia

It often starts with a physical examination and medical history review, followed by blood tests to check for abnormal cell counts. A bone marrow biopsy is then usually conducted to confirm the diagnosis by examining the marrow for leukemic cells. The combined results of these diagnostic methods contribute to a comprehensive understanding of the patient's condition and inform the healthcare team's treatment plan.

Treatment for Acute Myelomonocytic Leukemia

Treatment options for Acute Myelomonocytic Leukemia typically involve a combination of chemotherapy, targeted therapy, and stem cell transplantation. Chemotherapy is the primary approach to kill cancer cells and induce remission. Targeted therapy is used to specifically target certain molecules or genetic mutations present in the cancer cells. In some cases, stem cell transplantation may be considered to replace diseased bone marrow with healthy stem cells. 

Supportive care such as blood transfusions, antibiotics, and managing side effects is also crucial in the treatment plan. The choice of treatment depends on factors like the patient's overall health, genetic profile of the leukemia, and response to initial therapies. Close monitoring and follow-up are essential to track the disease's progression and adjust treatment as needed.
