High BCR-ABL/GUS(IS) levels at diagnosis of chronic phase CML are associated with unfavorable responses to standard-dose imatinib
2017
Abstract Purpose: The approval of second-generation tyrosine kinase inhibitors (TKIs) for the first-line treatment of chronic myeloid leukemia (CML) has generated an unmet need for baseline molecular parameters associated with inadequate imatinib responses. Experimental Design: We correlated BCR–ABL/GUSIS and BCR–ABL/ABL transcripts at diagnosis with the outcome—defined by the 2013 European LeukemiaNet recommendations—of 272 patients newly diagnosed with CML receiving imatinib 400 mg/daily. Applying receiver-operating characteristic curves, we defined BCR–ABL/GUSIS and BCR–ABL/ABL levels associated with lower probabilities of optimal response, failure-free (FFS), event-free (EFS), transform…

High BCR-ABL/GUSIS Levels At Diagnosis Are Associated With Unfavorable Responses To Imatinib
2013
Abstract The approval of three tyrosine kinase inhibitors (TKIs) for the first line treatment of Chronic Myeloid Leukemia (CML) has generated an urgent need for molecular parameters predictive of unfavorable therapeutic outcomes. Recent evidence suggests that failure to achieve early molecular responses (i.e. BCR-ABL/ABLIS levels <10% after 3 months or <1% after 6 months of TKI treatment) results in inferior rates of both overall and progression-free survival. With the current study, we wanted to establish if high BCR-ABL transcripts at diagnosis would be associated with unfavorable responses to Imatinib Mesylate (IM). Thus, we correlated quantitative determinations of BCR-ABL levels …
High BCR-ABL Levels At Diagnosis Are Associated with Unfavorable Responses to Imatinib Mesylate.
2012
Abstract Abstract 2790 The approval of second-generation tyrosine kinase inhibitors (TKIs) for the first line treatment of Chronic Myeloid Leukemia (CML) has generated a need for early molecular parameters associated with inadequate responses to Imatinib Mesylate (IM). Recent evidence suggests that CML patients presenting BCR-ABL/ABLIS levels >10% after 3 months of IM or >1% after 6 months of treatment have inferior outcomes in terms of both overall survival (OS) and progression-free survival. We wanted to establish if high BCR-ABL transcripts at diagnosis would also be associated with unfavorable responses to IM. To this end, we correlated quantitative determinations of BCR-ABL measu…
BCR-ABL1 Doubling-Times and Halving-Times May Predict CML Response to Tyrosine Kinase Inhibitors
2019
In Chronic Myeloid Leukemia (CML), successful treatment requires accurate molecular monitoring to evaluate disease response and provide timely interventions for patients failing to achieve the desired outcomes. We wanted to determine whether measuring BCR-ABL1 mRNA doubling-times (DTs) could distinguish inconsequential rises in the oncogene’s expression from resistance to tyrosine kinase inhibitors (TKIs). Thus, we retrospectively examined BCR-ABL1 evolution in 305 chronic-phase CML patients receiving imatinib mesylate (IM) as a first line treatment. Patients were subdivided in two groups: those with a confirmed rise in BCR-ABL1 transcripts without MR3.0 loss and those failing IM. We found …
