Tam et al 200849 | N=113 CP-CML (n=87) AP-CML (n=26) |
Nilotinib (n=43) or dasatinib (n=70) | MCyR vs MiCyR or CHR (by 1 y) | At 2 y: probability of progression 3% (with 1-y MCyR) vs 17% (with 1-y MiCyR or CHR), P=0.003 | At 2 y: 97% (with 1-y MCyR) vs 84% (with 1-y MiCyR or CHR), P=0.02 |
Jabbour et al 201150 | CP-CML (N=123) | Nilotinib (n=45) or dasatinib (n=78) | MCyR vs no MCyR (at 1 y) | After median follow-up of 38 mo: lack of 1-y MCyR adverse factor for EFS; HR=2.3, P<0.001 | NR |
Jabbour et al 201351 | CP-CML (N=123) | Nilotinib (n=45) or dasatinib (n=78) | CCyR vs no CCyR (at 3 mo) | At 3 y: 74% (with 3-mo CCyR) vs 43% (without 3-mo CCyR), P=0.002; multivariate analysis: HR=4.5 (95% CI, 2.12–11.66), P<0.01 | At 3 y: 98% (with 3-mo CCyR) vs 79% (without 3-mo CCyR), P=0.005; multivariate analysis: HR=5.4 (95% CI, 1.27–10.87), P=0.03 |
Abbreviations: AP = accelerated phase; CCyR = complete cytogenetic response; CHR = complete hematologic response; CI = confidence interval; CML = chronic myeloid leukemia; CP = chronic phase; EFS = event-free survival; HR = hazard ratio; MCyR = major cytogenetic response; MiCyR = minor cytogenetic response; NR = not reported; OS = overall survival; TKI = tyrosine kinase inhibitor.
