What is Leukaemia?

Leukaemia is a type of cancer that originates in the blood-forming tissues of the body, primarily the bone marrow and the lymphatic system. It involves the overproduction of immature white blood cells, which disrupts the normal functioning of the immune system and the production of other blood cells. This unchecked growth of abnormal cells can eventually infiltrate other organs and tissues, leading to severe health complications.

Types of Leukaemia

Leukaemia manifests in various forms, distinguished by the pace of disease progression and the specific type of white blood cells impacted. Understanding these different types is paramount for healthcare professionals to tailor treatment plans effectively and provide patients with the best possible care. Here are the main types of leukaemia:

• Acute Lymphoblastic Leukaemia (ALL): ALL is a rapidly progressing type of leukaemia affecting lymphoid cells, which form vital immune system components known as lymphocytes. It's commonly diagnosed in children but can occur in adults too. Treatment usually involves intensive chemotherapy, targeted therapy, and sometimes stem cell transplantation. Recent advancements in treatment have significantly improved the overall prognosis for ALL patients.
• Acute Myeloid Leukaemia (AML): AML develops from rapidly multiplying myeloid cells in the bone marrow, disrupting normal blood cell production. It's more prevalent in older adults but can occur at any age. Treatment may include chemotherapy, targeted therapy, and stem cell transplantation. Survival rates for some AML subtypes have improved with modern treatment approaches.
• Chronic Lymphocytic Leukaemia (CLL): CLL is characterized by the slow accumulation of dysfunctional lymphocytes in the bone marrow and blood. It mainly affects older adults, and some patients may not need immediate treatment upon diagnosis. Treatment options may include watchful waiting, chemotherapy, targeted therapy, immunotherapy, and stem cell transplantation for specific cases. While CLL isn't curable, ongoing research aims to enhance treatment outcomes and patient well-being.
• Chronic Myeloid Leukaemia (CML): CML results from genetic mutations leading to the overproduction of abnormal white blood cells called granulocytes. It progresses through different phases, including chronic, accelerated, and blast crisis phases. Treatment often involves targeted therapy with tyrosine kinase inhibitors (TKIs), which target the genetic mutation driving the disease. TKIs have revolutionized CML management, offering high response rates and improved survival for many patients.

The variety in types of leukaemia presents unique challenges and requires a tailored approach to diagnosis and treatment. By understanding the characteristics and nuances of each subtype, healthcare providers can better navigate treatment decisions and optimize outcomes for individuals affected by leukaemia.

Causes of Leukaemia

Leukaemia results from a complex interplay of genetic, environmental, and immunological factors. While precise triggers remain elusive, several risk factors have been identified:

• Genetic Predisposition: Family history or inherited genetic mutations can increase leukaemia risk. Disruptions in cellular processes due to genetic abnormalities may lead to uncontrolled cell growth.
• Radiation Exposure: Prolonged exposure to ionizing radiation, such as from nuclear accidents or medical treatments like radiotherapy, heightens leukaemia risk by damaging bone marrow cells' DNA.
• Chemical Exposure: Certain chemicals, like benzene found in gasoline and formaldehyde in household products, elevate leukaemia risk. Occupational exposure to these carcinogens necessitates strict safety measures.
• Immune System Disorders: Conditions like HIV/AIDS or autoimmune diseases weaken immune function, allowing abnormal cell proliferation. Immunosuppressive therapies may also heighten leukaemia risk.

While these factors contribute to leukaemia development, its causes are multifactorial. Ongoing research aims to uncover novel risk factors and develop targeted prevention strategies, empowering individuals to mitigate risk and promote overall well-being.

Symptoms of Leukaemia

The symptoms of leukaemia can vary depending on the type and stage of the disease. Common symptoms include:

• Fatigue and Weakness: Persistent feelings of exhaustion and reduced energy levels are often early indicators of leukaemia. These symptoms can result from anaemia, a condition arising from decreased red blood cell production.
• Frequent Infections: Leukaemia compromises the immune system, making individuals more susceptible to infections. Recurrent infections, such as respiratory or urinary tract infections, may occur with greater frequency and severity.
• Easy Bruising and Bleeding: A hallmark of leukaemia is impaired blood clotting, leading to easy bruising and prolonged bleeding from minor injuries. This is due to decreased platelet counts or dysfunctional platelets.
• Swollen Lymph Nodes: Enlarged lymph nodes, particularly in the neck, armpits, or groin, may indicate the involvement of the lymphatic system. Leukaemia can trigger lymph node swelling as abnormal cells accumulate within them.
• Night Sweats: Excessive sweating during sleep, known as night sweats, is a common symptom observed in individuals with leukaemia. It may be related to the body's response to inflammation or hormonal changes.
• Unexplained Weight Loss: Unintentional weight loss, often accompanied by a loss of appetite, can occur as the body diverts energy to combat the disease. This weight loss may occur despite adequate calorie intake.
• Bone Pain: Leukaemia cells may infiltrate the bone marrow, leading to bone pain, especially in the long bones of the arms and legs. This pain may be described as dull or deep and may worsen with movement.

Early detection and prompt medical intervention are crucial for improving outcomes and quality of life for individuals with leukaemia.

Leukaemia Treatments

Treating leukaemia requires a comprehensive approach tailored to each patient's specific circumstances. Therapeutic strategies often encompass a combination of modalities aimed at eradicating cancerous cells, restoring normal blood cell production, and minimizing disease recurrence. Here's an in-depth look at the various treatment options available:

• Chemotherapy: This treatment involves powerful drugs administered orally, intravenously, or directly into the cerebrospinal fluid to kill or inhibit cancer cells. While effective, it may cause side effects like nausea, hair loss, and increased infection risk.
• Radiation Therapy: High-energy beams target and destroy cancer cells, often used to treat localized areas like the brain or spleen, or before stem cell transplantation. Side effects may include fatigue, skin irritation, and long-term risks of secondary cancers.
• Targeted Therapy: Specific drugs target molecular alterations driving cancer growth, focusing on pathways like tyrosine kinases or immune checkpoints. These offer precise, less toxic treatment options, especially for specific genetic mutations or refractory diseases.
• Immunotherapy: It boosts the body's immune response to recognize and eliminate cancer cells. Approaches may include monoclonal antibodies, CAR-T cell therapy, or immune checkpoint inhibitors, offering durable responses with fewer adverse effects, particularly for refractory or relapsed cases.
• Stem Cell Transplantation: Also called bone marrow or hematopoietic stem cell transplantation, it replaces diseased bone marrow with healthy stem cells from a donor (allogeneic) or the patient (autologous). Aimed at restoring normal blood cell production and immune function, it can be curative but carries risks like graft-versus-host disease and infections.
• Clinical Trials: These evaluate novel treatments, combinations, and strategies, offering access to cutting-edge therapies. Participation contributes to understanding optimal treatment approaches, with recommendations based on patient characteristics and goals.
