Purpose: To review and update the European LeukemiaNet (ELN) recommendations for the management of chronic myeloid leukemia with imatinib and second-generation tyrosine kinase inhibitors (TKIs), including monitoring, response definition, and first- and second-line therapy.
Methods: These recommendations are based on a critical and comprehensive review of the relevant papers up to February 2009 and the results of four consensus conferences held by the panel of experts appointed by ELN in 2008.
Results: Cytogenetic monitoring was required at 3, 6, 12, and 18 months. Molecular monitoring was required every 3 months. On the basis of the degree and the timing of hematologic, cytogenetic, and molecular results, the response to first-line imatinib was defined as optimal, suboptimal, or failure, and the response to second-generation TKIs was defined as suboptimal or failure.
Conclusion: Initial treatment was confirmed as imatinib 400 mg daily. Imatinib should be continued indefinitely in optimal responders. Suboptimal responders may continue on imatinb, at the same or higher dose, or may be eligible for investigational therapy with second-generation TKIs. In instances of imatinib failure, second-generation TKIs are recommended, followed by allogeneic hematopoietic stem-cell transplantation only in instances of failure and, sometimes, suboptimal response, depending on transplantation risk.

Background: Chronic myeloid leukemia (CML) treatment has significantly evolved with the introduction of tyrosine kinase inhibitors. However, access to these treatments and outcomes vary globally. This study examines 2 decades of CML management in Colombia using the RENEHOC registry, focusing on TKI efficacy, safety, and healthcare system challenges.

: The implementation of tyrosine kinase inhibitors (TKIs) in the treatment of chronic myeloid leukemia (CML) has brought a significant improvement in the prognosis for CML patients and a decrease in the number of patients requiring allogeneic hematopoietic stem cell transplantation (allo-HCT). Nevertheless, the impact of TKIs on allo-HCT outcomes has not been thoroughly explored. : The main endpoint of our research was to assess the impact of prior TKI treatment on acute graft-versus-host disease (aGvHD) and chronic graft-versus-host disease (cGvHD).

Background: The clinical implications of different EML4-ALK fusion variants remain poorly elucidated in the era of second-generation ALK inhibitors.
Methods: This was a retrospective cohort study, wherein patients diagnosed with locally advanced or metastatic non-small cell lung cancer harboring EML4-ALK fusion were stratified into two cohorts based on their first-line treatment: Cohort 1 received alectinib, while Cohort 2 received crizotinib. Statistical analysis was employed to investigate the impact of different EML4-ALK variants and TP53 status on the efficacy of first-line ALK-TKIs.

Background: The treatment of chronic myeloid leukemia through tyrosine kinase inhibitors (TKIs) has achieved promising efficacy and safety outcomes, however the costs are associated with a substantial economic burden. The objective of this study was to develop a Markov model with a 20-year time horizon to assess the cost effectiveness of TKIs from a public healthcare system perspective in South Africa.
Methods: We constructed a Markov model to compare three strategies in which treatment was initiated with either imatinib, nilotinib, or dasatinib.

Background/purpose: Tyrosine kinase inhibitors (TKIs) have revolutionized chronic myeloid leukemia (CML) treatment, yet long-term pediatric outcomes and growth effects remain limited. This study describes the long-term efficacy and growth impact of TKIs in children and adolescents with CML.
Methods: We retrospectively reviewed 14 pediatric CML patients treated with TKIs at our institute.
