We recommend close monitoring with frequent checks, enhanced care with granulocyte colony stimulating factor (GCSF) support for grade 3-4 neutropenia, blood transfusion for severe anemia (Hb < 7g/dL), platelets for severe thrombocytopenia (< 10,000/μL) and thrombopoietin (TPO) mimetics such as eltrombopag or romiplostim for prolonged severe thrombocytopenia in patients at high-risk of hemorrhagic complications. Here, GSTM1 is linked to anemia (phenotype).
