Leukemia| Case based Approach | Pheripheral blood examination to Flow Cytometry Interpretations

Leukemia| Case based Approach | Pheripheral blood examination to Flow Cytometry Interpretations Leukemia is a type of cancer found in your blood and bone marrow and is caused by the rapid production of abnormal white blood cells. These abnormal white blood cells are not able to fight infection and impair the ability of the bone marrow to produce red blood cells and platelets. Leukemia can be either acute or chronic. Chronic leukemia progresses more slowly than acute leukemia, which requires immediate treatment. Leukemia is also classified as lymphocytic or myelogenous. Lymphocytic leukemia refers to abnormal cell growth in the marrow cells that become lymphocytes, a type of white blood cell that plays a role in the immune system. In myelogenous leukemia, abnormal cell growth occurs in the marrow cells that mature into red blood cells, white blood cells, and platelets. There are four broad classifications of leukemia: Acute lymphocytic leukemia (ALL) Acute myelogenous leukemia (AML) Chronic lymphocytic leukemia (CLL) Chronic myelogenous leukemia (CML) Leukemia occurs in both adults and children. ALL is the most common form ofchildhood leukemia, and AML is the second most common. Decades of research have led to vastly improved outcomes for children diagnosed with ALL. The two most common adult leukemias are AML and CLL. Am I at Risk? Although experts are uncertain about the causes of leukemia, they have identified several risk factors that include the following: Exposure to high levels of radiation Repeated exposure to certain chemicals (for example, benzene) Chemotherapy Down Syndrome A strong family history of leukemia Symptoms vary depending on the type and stage of leukemia, but they can include the following: Fever, chills, night sweats and other flu-like symptoms Weakness and fatigue Swollen or bleeding gums Headaches Enlarged liver and spleen Swollen tonsils Bone pain Paleness Pinhead-size red spots on the skin Weight loss How Is Leukemia Treated? Your doctor will conduct a complete blood count (CBC) to determine if you have leukemia. This test may reveal if you have leukemic cells. Abnormal levels of white blood cells and abnormally low red blood cell or platelet counts can also indicate leukemia. If you test positive for leukemia, your doctor will perform a biopsy of your bone marrow to determine which type you have. Treatment depends on your age, general health, and type of leukemia. You might receive a combination of treatments that could include chemotherapy, biological therapy, radiation therapy, and stem cell transplantation. Patients with acute leukemia often undergo chemotherapy because this type of treatment targets fast-dividing cells. Many acute leukemia patients have responded successfully to treatment. On the other hand, because the cells divide more slowly in chronic leukemia, it is better treated with targeted therapies that attack slowly dividing cells as opposed to traditional chemotherapy that targets rapidly dividing cells. For some patients, participating in a clinical trial provides access to experimental therapies. If you are diagnosed with leukemia, talk with your doctor about whether joining a clinical trial is right for you. Is Leukemia Preventable? Because the cause of leukemia remains unknown, there is no certain way to prevent it. However, avoiding exposure to solvents, such as benzene and toluene, and unnecessary exposure to x-rays is generally good practice. If you think you may be exhibiting signs of leukemia, being aware of the risk factors and symptoms and talking with your doctor are critical to early diagnosis and treatment. It is especially important for people who have a family history of leukemia to be aware of symptoms and share their family medical history with their doctors. #leukemia #casebasedappraoch #pheripherlabloodexamination #flowcytometryinterpretations
