Question

Quizplus · Accepted Answer

Neutrophils are a type of white blood cell that play a key role in the immune response. In acute myelogenous leukemia, the bone marrow produces immature white blood cells that prevent the production of mature cells, including neutrophils. Therefore, a low percentage of neutrophils indicates poor response to treatment. However, if the percentage of neutrophils increases, it indicates that the bone marrow is producing more mature cells, which is a sign of a positive response to treatment. Platelet counts, myeloid to lymphocyte ratios, and red blood cell counts may also be affected in leukemia, but they do not necessarily indicate a positive response to chemotherapy.
