摘要: Cytogenetic and molecular responses to standard-dose imatinib (IM) were correlated with trough IM plasma levels for 78 patients chronic myeloid leukemia (CML) after a minimum of 12 months therapy. The mean level was 1065 ng/ml (range, 203-2910). There no correlation complete cytogenetic response (CCR) at 1 year (CCR 1010 vs CCR 1175 P=.29) or major (MMR) (MMR1067 MMR 1063 P=.74) median 1298 days did correlate Sokal risk scores the odds achieving low high score 10.8 (95% CI 2.2-53.5) 6.4 1.4-29.4), respectively. Furthermore, longer duration therapy also associated greater likelihood (P=.02).
