 The current study was conducted to compare simultaneously obtained bone marrow (BM) cytogenetics (CTG), peripheral blood (PB) and BM fluorescence in situ hybridization (FISH), and quantitative real-time polymerase chain reaction (Q-PCR) for BCR-ABL1 in monitoring response to treatment with tyrosine kinase inhibitors and homoharringtonine (HHT) in patients with chronic myeloid leukemia (CML).     ///    "PB and BM FISH (n = 112 samples) and/or Q-PCR (n = 132 samples) for BCR-ABL1 were simultaneously obtained in 70 patients with Philadelphia chromosome-positive (Ph+) CML in chronic (68%), accelerated (16%), and blast phase (16%) before the initiation of therapy and during the course of treatment with imatinib (IM) (n = 40 patients), dasatinib (n = 20 patients), nilotinib (n = 4 patients), bosutinib (n = 18 patients), or HHT (n = 4 patients) for patients with newly diagnosed (n = 13 patients), IM-sensitive (n = 34 patients), IM-resistant (n = 30 patients), or IM-intolerant (n = 9 patients) disease.
