In leukemia, what happens to the platelet count?

• A. High
• B. Low
• C. Unchanged
• D. Only increases if treated

Answer: (B)

In leukemia, the platelet count typically decreases, resulting in thrombocytopenia, which is characterized by fewer platelets in the bloodstream. This drop in platelet levels occurs due to several factors related to the disease process. Leukemia involves the uncontrolled proliferation of abnormal white blood cells that disrupt normal bone marrow function. As these leukemic cells expand, they crowd out the normal hematopoietic cells, including those responsible for producing platelets. Hence, the overall production of platelets is diminished, leading to a lower platelet count. The risk of bleeding and bruising rises with this low platelet count, which can significantly impact a patient’s clinical management and quality of life. Monitoring platelet levels becomes crucial in managing patients with leukemia, particularly when planning treatment, as low counts can affect the types of therapies that can be safely administered.
