Measurement of imatinib plasma concentration can be useful to evaluate patient adherence to daily oral therapy, potential drug–drug interaction, treatment efficacy, and severe drug-related adverse events. The aim of this study was to correlate the two different blood level test methods, HPLC–UV and LC–MS/MS. We analyzed 162 plasma samples from patients treated with imatinib. We estimated the correlation between the two analytical methods on total data set and on five sets of patients grouped into different categories based on the drug-dose therapy. Finally, imatinib quantification was correlated with genetic data on the molecular response in monitoring follow-up of CML patients.

Abstract
Measurement of imatinib plasma concentration can be useful to evaluate patient adherence to daily oral therapy, potential drug–drug interaction, treatment efficacy, and severe drug-related adverse events. The aim of this study was to correlate the two different blood level test methods, HPLC–UV and LC–MS/MS. We analyzed 162 plasma samples from patients treated with imatinib. We estimated the correlation between the two analytical methods on total data set and on five sets of patients grouped into different categories based on the drug-dose therapy. Finally, imatinib quantification was correlated with genetic data on the molecular response in monitoring follow-up of CML patients.
