Response after dose increase in patients with imatinib failure
Outcome | Total, n = 84 | Cytogenetic failure, n = 63 | Hematologic failure, n = 21 | P |
---|---|---|---|---|
Cytogenetic response, n (%) | ||||
Any | 50 (60) | 47 (75) | 3 (14) | < .001 |
Partial* | 10 (14) | 8 (16) | 2 (10) | .77 |
Complete | 34 (40) | 33 (52) | 1 (5) | < .001 |
% 2-year | ||||
EFS | 57 | 65 | 36 | < .001 |
FFS | 29 | 38 | 5 | < .001 |
TFS | 73 | 80 | 51 | .004 |
OS | 84 | 90 | 67 | < .001 |
EFS indicates event-free survival; FFS, failure-free survival; TFS, transformation-free survival; and OS, overall survival.
Only patients (n = 71) not in MCyR at the time of imatinib dose escalation were evaluable.
