Understanding Acute Myeloid Leukaemia: Symptoms and Treatment
Acute Myeloid Leukaemia (AML) is a complex and aggressive cancer of the blood and bone marrow. This malignancy, characterized by the rapid growth of abnormal white blood cells, interferes with the production of normal blood cells. Understanding the symptoms, causes, and treatment options is crucial for managing this condition effectively.
Causes and Risk Factors for Acute Myeloid Leukaemia
AML arises from a series of genetic mutations in the DNA of developing bone marrow cells. These mutations result in abnormal cell growth, leading to the accumulation of immature blood cells known as myeloblasts. While the exact cause of these genetic mutations remains unclear, several risk factors have been identified:
- Age: The incidence of AML increases with age, with the majority of cases diagnosed in adults over 65.
- Genetic Disorders: Conditions such as Down syndrome and other congenital genetic disorders are associated with a higher risk of developing AML.
- Previous Cancer Treatment: Exposure to chemotherapy or radiation therapy for other cancers may increase the risk.
- Chemical Exposure: Prolonged exposure to certain chemicals, including benzene, is linked to a higher incidence of AML.
- Smoking: Tobacco use has been implicated as a potential risk factor.

The symptoms of AML can vary widely and may resemble those of other medical conditions, making diagnosis challenging. Common symptoms include:
- Fatigue and Weakness: Due to anemia, patients may experience persistent tiredness and lack of energy.
- Frequent Infections: A reduced white blood cell count can lead to recurrent infections.
- Bruising and Bleeding: Thrombocytopenia, or a low platelet count, can result in easy bruising and bleeding.
- Bone Pain: Some patients report pain in bones or joints due to the accumulation of abnormal cells.
- Fever: Unexplained fevers may occur as the body's response to abnormal cells.
- Weight Loss: Unintentional weight loss and loss of appetite are common symptoms.
Diagnosing Acute Myeloid Leukaemia
Diagnosis of AML involves a comprehensive evaluation, including:
- Complete Blood Count (CBC): A CBC can reveal abnormalities in white blood cells, red blood cells, and platelets.
- Bone Marrow Aspiration and Biopsy: These procedures are essential for confirming the presence of leukaemic cells in the bone marrow.
- Cytogenetic Analysis: This test identifies specific genetic abnormalities associated with AML, aiding in prognosis and treatment planning.
- Immunophenotyping: This technique involves identifying particular markers on the surface of cells to differentiate AML from other types of leukaemia.
Acute Myeloid Leukaemia vs. Chronic Leukaemia
AML is an acute form of leukaemia, characterized by the rapid progression and accumulation of immature blood cells. In contrast, chronic leukaemias, such as Chronic Myeloid Leukaemia (CML), progress more slowly and involve the accumulation of more mature blood cells. Understanding the differences is critical for determining the appropriate management strategy.
Acute Myeloid Leukaemia Treatment Options
Treatment for AML is aggressive and often involves a combination of therapies. The primary treatment options include:
Chemotherapy
Chemotherapy remains the cornerstone of AML treatment. The goal is to induce remission by eradicating leukaemic cells. Treatment typically involves two phases:
- Induction Therapy: This initial phase aims to destroy as many leukaemic cells as possible to achieve remission.
- Consolidation Therapy: Following remission, consolidation therapy is administered to eliminate any remaining cancer cells and prevent relapse.
Targeted Therapy
Targeted therapies specifically attack cancer cells by interfering with molecules involved in their growth and survival. These therapies are particularly effective in cases where specific genetic mutations, such as FLT3 or IDH2, are present.
Stem Cell Transplantation
A stem cell transplant, also known as a bone marrow transplant, may be considered for eligible patients. This procedure involves replacing diseased bone marrow with healthy stem cells, enabling the production of normal blood cells.
Clinical Trials
Participation in clinical trials offers access to novel therapies and treatments that may not be widely available. Clinical trials are vital in advancing the understanding and treatment of AML.

AML and its treatment can lead to various complications, including:
- Infections: Due to a compromised immune system, patients are at an increased risk of infections.
- Bleeding: Low platelet counts can result in severe bleeding episodes.
- Organ Damage: Treatment may cause damage to organs such as the heart, liver, or kidneys.
Effective management of these complications involves regular monitoring, supportive care, and prompt treatment of any arising issues.
Acute Myeloid Leukaemia Prognosis
The prognosis for AML depends on several factors, including the patient's age, overall health, and the specific genetic mutations present. While advances in treatment have improved outcomes, the prognosis remains challenging, particularly for older adults.
