The BCR-ABL specific Tyrosine Kinase Inhibitors (TKI) changed the outcome of Chronic Myeloid Leukemia (CML), turning a life-threatening disease into a chronic illness. However, TKI are not yet curative, since most patients retain leukemic stem cells (LSC) and their progenitors in bone marrow and relapse following treatment cessation. At diagnosis, deregulations of the Bone Morphogenetic Proteins (BMP) pathway are involved in LSC and progenitors expansion. Here, we report that BMP pathway alterations persist in TKI-resistant patients...

T cell immune surveillance is considered an important host protection process for inhibiting carcinogenesis. The full capacity of T cell immune surveillance is dependent on T cell homeostasis, particularly for central memory T (TCM) cells and stem cell memory T (TSCM) cells. In this study, distribution of T cell subsets in peripheral blood from 12 patients with chronic myeloid leukemia (CML) and 12 cases with CML in complete remission (CR) was analyzed using a multicolor flow cytometer, and 16 samples from healthy individuals (HIs) served as control...

Tyrosine kinase inhibitors (TKIs), including imatinib (IM), improve the outcome of chronic myelogenous leukemia (CML) therapy. However, TKI treatment is long-term and can induce resistance to TKIs, which often leads to a poor clinical outcome in CML patients. Here, we examined the effect of continuous IM exposure on intracellular energy metabolism in K562 cells, a human Philadelphia chromosome-positive CML cell line, and its subsequent sensitivity to anti-cancer agents. Contrary to our expectations, we found that continuous IM exposure increased sensitivity to TKIs...

Many tyrosine kinase-driven cancers, including chronic myeloid leukemia (CML), are characterized by high response rates to specific tyrosine kinase inhibitors (TKIs) like imatinib. In East Asians, primary imatinib resistance is caused by a deletion polymorphism in Intron 2 of the BIM gene, whose product is required for TKI-induced apoptosis. The deletion biases BIM splicing from exon 4 to exon 3, generating splice isoforms lacking the exon 4-encoded pro-apoptotic BH3 domain, which impairs the ability of TKIs to induce apoptosis...

INTRODUCTION: Since the first fusion gene was discovered decades ago, a considerable number of fusion genes have been detected in leukemia. The majority of them are generated through chromosomal rearrangement or abnormal transcription. With the development of techniques, high-throughput sequencing method makes it possible to detect fusion genes systematically in multiple human cancers. Owing to their biological significance and tumor-specific expression, some of the fusion genes are attractive diagnostic tools and therapeutic targets...

The tyrosine kinase inhibitor (TKI) imatinib was rationally designed to target BCR-ABL1 which is constitutively activated in chronic myeloid leukemia (CML). Following the tremendous success in adults, imatinib also became licensed for treatment of CML in minors. The rarity of pediatric CML hampers the conduction of formal trials. Thus, imatinib is still the single TKI approved for CML treatment in childhood. Areas covered: This review attempts to provide an overview of the literature on pharmacology, pharmacokinetic, and pharmacogenetic of imatinib concerning pediatric CML treatment...

PURPOSE: Leukemia stem cells (LSCs) are important source of tyrosine kinase inhibitor (TKI) resistance and disease relapse in chronic myelogenous leukemia (CML). Targeting LSCs may be an attractive strategy to override this thorny problem. Given that EZH2 was overexpressed in primary CML CD34+ cells, our purpose in this study was to evaluate the effects of targeting EZH2 on CML LSCs and clarify its underlying mechanism. Experimental Design:Human primary CML CD34+ cells and retrovirally-BCR-ABL-driven CML mouse model were employed to evaluate the effects of suppression of EZH2 by GSK126 or EZH2 specific shRNA in vitro and in vivo...

Tyrosine kinase inhibitors (TKIs) improve the prognosis of patients with chronic myelogenous leukemia (CML) by inducing substantial deep molecular responses (DMRs); some patients could successfully discontinue TKI therapy after maintaining DMR for ≥1 year. In this cessation study, we investigated the optimal conditions for dasatinib discontinuation in patients who maintained DMR for ≥2 years. This study included 54 patients with CML who were enrolled in D-STOP multicenter prospective trial, had achieved DMR, and had discontinued dasatinib after 2-year consolidation...

Although imatinib has dramatically improved major outcomes in patients with chronic myeloid leukemia (CML), there are newer tyrosine kinase inhibitors (TKIs) approved worldwide for the treatment of resistant cases, and two second-generation TKIs (dasatinib, nilotinib) are approved in some nations for treating patients in the upfront setting. Radotinib (IY5511HCL, Supect®) is a novel and selective second-generation BCR-ABL1 TKI, which is currently approved in Korea for the treatment of patients with CML both in the upfront and salvage settings...

During the last 10 years, clinical trials formally demonstrated that about 50% of patients with chronic phase (CP) chronic myeloid leukaemia (CML) who achieve and maintain deep molecular responses for a prolonged period of time during treatment with imatinib or new generation tyrosine kinase inhibitors (TKIs) may successfully stop their anti-leukaemic therapy. Based on the accumulated knowledge from abundant clinical trial experience, TKI discontinuation is becoming an important goal to achieve and is about to enter clinical practice...

BACKGROUND: Chronic myeloid leukemia (CML) is a clonal myeloproliferative disorder with heterogeneous biological and clinical features. The biomolecular mechanisms of CML response to tyrosine-kinase inhibitors are not fully defined. OBJECTIVE: We undertook a gene expression profiling (GEP) study of selected bone marrow (BM) CD34+/lin- cells of chronic-phase CML patients at diagnosis and after 12 months of TKI nilotinib to investigate molecular signatures characterizing both conditions...

BACKGROUND CML presenting with a variant Philadelphia translocation, atypical BCR-ABL transcript, additional chromosomal aberrations, and evolving MDS is uncommon and therapeutically challenging. The prognostic significance of these genetic findings is uncertain, even as singular aberrations, with nearly no data on management and outcome when they coexist. MDS evolving during the course of CML may be either treatment-associated or an independently coexisting disease, and is generally considered to have an inferior prognosis...

Chronic myeloid leukemia (CML) is a stem cell (SC) neoplasm characterized by the BCR/ABL1 oncogene. Although the disease can be kept under control using BCR/ABL1 tyrosine kinase inhibitors (TKIs) in most cases, some patients relapse or have resistant disease, so there is a need to identify new therapeutic targets in this malignancy. Recent data suggest that leukemic SCs (LSCs) in CML display the stem-cell (SC)-mobilizing cell surface enzyme dipeptidyl-peptidase IV (DPPIV = CD26) in an aberrant manner. In the present study, we analyzed the effects of the DPPIV blocker vildagliptin as single agent or in combination with the BCR/ABL1 TKI imatinib or nilotinib on growth and survival of CML LSCs in vitro and on LSC engraftment in an in vivo xenotransplantation nonobese diabetic SCID-IL-2Rγ(-/-) (NSG) mouse model...

Tyrosine kinase inhibitors (TKIs) are essential for the treatment of chronic myeloid leukemia (CML). Adverse effects of dasatinib have been reported; however, few reports have highlighted the association between dasatinib and demyelinating peripheral neuropathy (DPN). We report a patient with CML who developed acute onset of DPN associated with dasatinib therapy. A 46-year-old Japanese woman was treated with dasatinib for 7 months after the diagnosis of CML and she achieved a major molecular response (MMR)...

Additional cytogenetic abnormalities (ACA) are considered a high risk feature in chronic myeloid leukemia (CML). However, its prognostic significance at the time of diagnosis in the setting of new tyrosine kinase inhibitors (TKIs) is less well understood. Patients with CML in CP with or without ACA at diagnosis treated with frontline TKIs in prospective clinical trials were analyzed for outcomes. Among 603 patients treated, 29 (5%) had ACA. Patients with ACA included 2 of 72 (2.8%) treated with imatinib 400 mg, 9 of 207 (4...

Chronic myeloid leukemia (CML) is a myeloproliferative disease caused by the BCR-ABL1 tyrosine kinase (TK). The development of TK inhibitors (TKIs) revolutionized the treatment of CML patients. However, TKIs are not effective to those at advanced phases when amplified BCR-ABL1 levels and increased genomic instability lead to secondary oncogenic modifications. Wiskott-Aldrich syndrome protein (WASP) is an important regulator of signaling transduction in hematopoietic cells and was shown to be an endogenous inhibitor of the c-ABL TK...

OBJECTIVES: Newer tyrosine kinase inhibitors (TKIs) (bosutinib, ponatinib) and allogeneic hematopoietic stem cell transplantation (allo-HSCT) can be utilized as a salvage therapy in patients with chronic myeloid leukemia (CML) who failed two lines (imatinib → nilotinib or imatinib → dasatinib) of TKI therapy. However, these TKIs are not available in many countries and not all patients can undergo allo-HSCT.

PURPOSE OF REVIEW: Chronic myelogenous leukemia (CML) is a chronic myeloproliferative neoplasm characterized by the presence of Philadelphia chromosome [t(9:22)] leading to the presence of pathognomonic fusion gene product, BCR-ABL1. This leads to constitutive activation of ABL1 kinase. CML was a difficult-to-treat illness until the advent of small molecule tyrosine kinase inhibitor (TKI), imatinib which revolutionized therapy of CML. Since then, multiple second- and third-generation TKIs have been formulated which have proven effective and has led to marked improvement in survival...
