A low leukocyte count of 2.8 x 10^9/L and a low neutrophil count of 1.07 x 10^9/L on chemotherapy suggests that chemotherapy has suppressed bone marrow hematopoiesis and that leukopenia and neutropenia have occurred.
Chemotherapy can lead to bone marrow suppression, and leukopenia is defined as a persistent white blood cell count in the peripheral blood of an adult that is less than 4.0 x 10^9/L. Because the main components of white blood cells are neutrophils and lymphocytes, leukopenia is mainly caused by neutropenia. Neutropenia is a neutrophil count below 2.0 x 10^9/L.
Chemotherapy-induced leukopenia and neutropenia should be taken seriously and actively treated, such as human granulocyte stimulating factor to promote bone marrow hematopoietic recovery, etc., the specific use of drugs need to be carried out under the guidance of a physician.
