Our patient was diagnosed with chronic myeloid leukemia (CML) in chronic phase (CP) when he was 40 years old. Although dasatinib (DAS) was prescribed during his clinical course, he was poorly compliant with the treatment. In November 20XX, at 65 years of age, he visited our hospital with leukocytosis. He was diagnosed with CML in CP and recommenced DAS at 50 mg/day, achieving a complete hematological response after 2 months. However, DAS was increased to 100 mg/day because only minimum cytogenetic response ...
Abl1 is a protein tyrosine kinase whose aberrant activation due to mutations is the culprit of several cancers, most notably chronic myeloid leukaemia. Several Abl1 inhibitors are used as anti-cancer drugs. Unfortunately, drug resistance limits their effectiveness. The main cause for drug resistance is mutations in the kinase domain (KD) of Abl1 that evolve in patients. The T315I mutation confers resistance against all clinically-available inhibitors except ponatinib. Resistance to ponatinib can develop by ...
Leukemias are malignancies in which abnormal white blood cells are produced in the bone marrow, resulting in compromise of normal bone marrow hematopoiesis and subsequent cytopenias. Leukemias are classified as myeloid or lymphoid depending on the type of abnormal cells produced and as acute or chronic according to cellular maturity. The four major types of leukemia are acute myeloid leukemia, chronic myeloid leukemia, acute lymphoblastic leukemia, and chronic lymphocytic leukemia. Clinical manifestations a...
In this paper, a clinical case of combination of chronic myeloid leukemia and T-lymphoblastic lymphoma is present-ed, which is currently a rather rare finding for a clinician. The diagnosis of T-lymphoblastic lymphoma is establishedafter 2 years from the verification of chronic myeloid leukemia. The course of diseases and approaches to treatmentare described.The pathogenetic relationship between myeloid and lymphoid diseases remains unclear and is likely to be the resultof several factors - radiation, chemi...
A 42-year-old female complaining of fever and night sweats was diagnosed with acute megakaryoblastic blast phase chronic myeloid leukemia (CML-BP). She had massive splenomegaly, left pleural effusion with leukemia infiltration, and moderate myelofibrosis. She received dasatinib monotherapy (140 mg/day) as for induction, after which her pleural effusion rapidly resolved and hematological remission was achieved. However, CML relapsed 4 months after starting dasatinib due to increased BCR-ABL fusion signals i...
Chronic myeloid leukaemia (CML) is a neoplastic disorder of myeloid cell lines and is a less aggressive disease compared to acute myeloid leukemia (AML). Although cardiovascular complications are not uncommon, intracardiac thrombosis in CML is rarely reported. Herein, we report a case of CML presenting with an intracardiac thrombus attached to the posterior mitral leaflet, and subsequently resulting in peripheral embolization.
The abnormal cell types in chronic myeloid leukemia (CML) and monoclonal gammopathy of uncertain (MGUS) are quite different, being myeloid and plasma cells, respectively. The coexistence of CML and MGUS is an uncommon event, which is seldom reported in literature.
Philadelphia chromosome positive acute myeloid leukemia (Ph+ AML) is a rare subtype of AML that is now included as a provisional entity in the 2016 revised WHO classification of myeloid malignancies. However, a clear distinction between de novo Ph+ AML and chronic myeloid leukemia blast crisis is challenging. It is still a matter of debate whether Ph+ AML patients should be treated with chemotherapy or tyrosine kinase inhibitors as first-line therapy.
In this study we aimed to evaluate appropriate time points for mutation analysis of chronic myeloid leukemia.
Atypical chronic myeloid leukemia (aCML) and chronic neutrophilic leukemia (CNL) are rare BCR-ABL1 fusion gene-negative myeloid neoplasms with a predominance of neutrophils. Since no standard therapeutic strategy currently exists for these diseases, we retrospectively evaluated the outcomes of allogeneic hematopoietic stem cell transplantation (allo-HSCT) for aCML and CNL. Data from 14 aCML and 5 CNL patients as their diagnoses were collected using a nationwide survey. Allo-HSCT was performed between 2003 a...
Tyrosine kinase inhibitors (TKIs) are the standard treatment for chronic myeloid leukemia (CML). Despite their clinical success, TKIs are faced with challenges such as treatment resistance, which may be driven by kinase domain mutations, and frequent disease relapse upon the cessation of treatment. The combination of arsenic trioxide (ATO) and interferon-α (IFN) was previously demonstrated to inhibit proliferation and induce apoptosis in CML cell lines, prolong the survival of primary wild-type CML mice, a...
Atypical chronic myeloid leukemia (aCML) is a rare hematological malignancy with dismal prognosis, usually being reported as isolated disease or in association with other myeloid neoplasms. Treatment strategies used for MDS and MPN, as hypomethylating agents (HMA) or kinase inhibitors, may be considered although experience is limited. We biologically studied an old patient affected by aCML unusually mutated for both SETBP1 and CSF3R, with concomitant chronic lymphocytic leukemia (CLL). Decitabine (DCA) ther...
Leukemia is the second common blood cancer after lymphoma, and its incidence rate has an increasing trend in recent years. Leukemia can be classified into four types: acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), chronic lymphocytic leukemia (CLL), and chronic myelogenous leukemia (CML). More than forty drugs are applicable for different types of leukemia based on the discrepant pathogenesis. Therefore, the identification of specific drug-targeted biological processes and pathways is hel...
Adverse effects from childhood leukemia treatment may persist or present years after cure from cancer. We provide a comprehensive evaluation of subsequent hospitalization in five-year survivors of childhood acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), and chronic myeloid leukemia (CML).
As a potential target for cancer treatment, the C-Myc high expresses abnormally in a variety of solid tumors and hematological malignancies in humans. In hematologic malignancies, the increasing expression of C-Myc is associated with poor prognosis of patients diffuse large B-cell lymphoma. However, some studies have shown that high expression of C-Myc might be one of the mechanisms of disease progression and abrupt change, therefore, it can promote the transformation of chronic myeloid leukemia. Besides, t...
In the current study, the authors determined whether adhering to molecular monitoring guidelines in patients with chronic myeloid leukemia (CML) is associated with major molecular response (MMR) and assessed barriers to adherent monitoring.
Data on Chronic Myeloid Leukemia (CML) prevalence are scarce. Here we provide an estimation of the prevalence of CML in France for the year 2014 using French national health insurance data.
Discovery of (E)-N-(4-((4-methylpiperazin-1-yl)methyl)-3-(trifluoromethyl)phenyl)-3-((3-(2-(pyridin-2-yl)vinyl)-1H-indazol-6-yl)thio)propanamide (CHMFL-ABL-121) as a highly potent ABL kinase inhibitor capable of overcoming a variety of ABL mutants including T315I for chronic myeloid leukemia.
There is still a great demand in the clinic for the drugs which can overcome a variety of imatinib resistant ABL mutants. Starting from a type I inhibitor axitinib, which has been reported to overcome ABL-T315I mutant induced resistance, through a structure guided drug design approach and binding mode switch strategy, we have discovered a novel type II ABL inhibitor 24 (CHMFL-ABL-121), which significantly improved the inhibitory activity against ABL wt and a broad spectrum of mutants including the most prev...
The diagnosis of chronic myeloid leukemia (CML) is based on characteristic clinical and laboratory findings and the presence of BCR/ABL1 in the blood and/or bone marrow (BM). The utility of BM core biopsy in the workup of patients with CML has been questioned.
Cardiovascular events (CVEs) have been observed in patients with chronic myeloid leukemia treated with second-generation tyrosine kinase inhibitors.
Preclinical evidence indicates that the bone marrow microenvironment provides a protective niche for leukemic stem cells, allowing them to evade the effects of BCR-ABL tyrosine kinase inhibitors (TKIs), but that targeting of the JAK-STAT pathway with the JAK2 inhibitor ruxolitinib increases TKI-induced apoptosis. A phase I clinical trial (NCT01702064) investigated the tolerability and safety of treating chronic-phase chronic myeloid leukemia patients with ruxolitinib in combination with the BCR-ABL TKI nilo...
High hyperdiploidy (HD) is the most common cytogenetic subtype of childhood acute lymphoblastic leukemia (ALL), and a higher incidence of HD has been reported in ALL patients with congenital cancer syndromes. We assessed the frequency of predisposing germline mutations in 57 HD-ALL patients from the California Childhood Leukemia Study (CCLS) via targeted sequencing of cancer-relevant genes. Three out of 57 patients (5.3%) harbored confirmed germline mutations that were likely causal, in NBN, ETV6, and FLT3,...
