OBJECTIVE: To evaluate efficacy and safety of second-generation tyrosine kinase inhibitors (TKI) dasatinib, nilotinib and imatinib in treatment of newly diagnosed patients with chronic-phase chronic myeloid leukemia (CML).
METHODS: The clinical data and follow-up results of 163 patients with chronic-phase chronic myeloid lenkemia(CP-CML) who were treated in our hospital during the nearly 3 years were analysed retrospectively, among 163 patients 47 received dasatinib, 43 received nilotinib and 73 received imatinib. The efficacy, disease progression and safety were evaluated.
RESULTS: After treatment for 3 months, the rate of complete hematologic response(CHR) in three treatment groups were 77%, 79% and 67%, respectivily, CHR at 12 months in three treatment groups were 92%, 91% and 90%, respectively. By 3 months, the rates of complete cytogenetic response(CCyR) with dasatinib and nilotinib were higher than that with imatinib (55%, 53% vs 33%)(P<0.05 for both comparisons), CCyR at 12 months in three treatment groups were 86%, 88% vs 69% (P<0.05 for both comparisons). The rates of major molecular response(MMR) for dasatinib (11%) and nilotinib (9%) by 3 months were significantly higher than that for imatinib (1%) (P<0.05 for both comparisons), MMR at 12 months in three treatment groups were 49%, 50% and 28%, respectively (P<0.05 for both comparison). Progression to the accelerated or blast phase of CML occurred in 2 (4%) patients received dasatinib, 2 (5%) received nilotinib and 6 (8%) received imatinib. The safety profiles of these 3 second-generation TKI treatments were similar.
CONCLUSION: Both dasatinib and nilotinib induced strikingly higher and faster rates of complete cytogenetic response and major molecular response, with a statistically significant difference from imatinib.
