GSTM1 and myelodysplastic syndrome: Comparing data from 50 neutropenic (Neutp) to 50 non-neutropenic (Non-Neutp) MDS patents, we found that hematologic parameters other than ANC, most known as prognostic markers (Hb, WBC, lymphocyte, monocyte and platelet counts), were significantly lower in the Neutp than in Non-Neutp patients.
