摘要: Dasatinib is an inhibitor of BCR-ABL and SRC-family kinases for patients with imatinib-resistant or -intolerant chronic myelogenous leukemia (CML). In this international phase II trial, dasatinib was administered orally (70 mg twice daily) to myeloid blast (MBP, n=109) lymphoid (LBP, n=48) CML. After a minimum follow-up 12 months (range 0.03-20.7 months), major hematologic responses were induced in 34% (MBP-CML) 35% (LBP-CML) patients. Major cytogenetic attained 33% 52% complete 26 46%, respectively. Median progression-free survival 6.7 3.0 months. overall 11.8 5.3 Overall, had acceptable tolerability. Fluid retention events more frequent the MBP-CML than LBP-CML cohort: pleural effusion occurred 36 13% (all grades) 15 6% (grades 3/4), Other non-hematologic side effects primarily grade 1/2; 3/4 recorded
