Chronic myeloid leukemia (CML) is a myeloproliferative neoplasm characterized by three phases: chronic, accelerated, and blast phase. However; first- and second-generation tyrosine kinase inhibitors are used for the treatment of CML with common and uncommon adverse events. Here, we report a 24-year-old male with CML in chronic phase started on imatinib as upfront medication who developed tremor and recovered spontenously after 3 years.

Gastrointestinal Adverse Events

Tyrosine kinase inhibitors (TKIs) are the frontline therapy for BCR-ABL (Ph+) chronic myeloid leukemia (CML). A systematic meta-analysis of 43 peer-reviewed studies with 10,769 CML patients compared the incidence of gastrointestinal adverse events (GI AEs) in a large heterogeneous CML population as a function of TKI type. Incidence and severity of nausea, vomiting, and diarrhea were assessed for imatinib, dasatinib, bosutinib, and nilotinib. Examination of combined TKI average GI AE incidence found diarrhea most prevalent (22.5%), followed by nausea (20.6%), and vomiting (12.9%). Other TKI GI AEs included constipation (9.2%), abdominal pain (7.6%), gastrointestinal hemorrhage (3.5%), and pancreatitis (2.2%). Mean GI AE incidence was significantly different between TKIs (p < 0.001): bosutinib (52.9%), imatinib (24.2%), dasatinib (20.4%), and nilotinib (9.1%). Diarrhea was the most prevalent GI AE with bosutinib (79.2%) and dasatinib (28.1%), whereas nausea was most prevalent with imatinib (33.0%) and nilotinib (13.2%). Incidence of grade 3 or 4 severe GI AEs was ≤3% except severe diarrhea with bosutinib (9.5%). Unsupervised clustering revealed treatment efficacy measured by the complete cytogenetic response, major molecular response, and overall survival is driven most by disease severity, not TKI type. For patients with chronic phase CML without resistance, optimal TKI selection should consider TKI AE profile, comorbidities, and lifestyle.

Metabolomic Analysis

Background: Cardiovascular adverse events (CV-AEs) are considered critical complications in chronic myeloid leukemia (CML) patients treated with second- and third-generation tyrosine kinase inhibitors (TKIs). The aim of our study was to assess the correlation between metabolic profiles and CV-AEs in CML patients treated with TKIs. Methods: We investigated 39 adult CML patients in chronic-phase (mean age 49 years, range 24–70 years), with no comorbidities evidenced at baseline, who were consecutively identified with CML and treated with imatinib, nilotinib, dasatinib, and ponatinib. All patients performed Gas-Chromatography-Mass-Spectrometry-based metabolomic analysis and were divided into two groups (with and without CV-AEs). Results: Ten CV-AEs were documented. Seven CV-AEs were rated as 3 according to the Common Toxicity Criteria, and one patient died of a dissecting aneurysm of the aorta. The patients’ samples were clearly separated into two groups after analysis and the main discriminant metabolites were tyrosine, lysine, glutamic acid, ornithine, 2-piperdinecarboxylic acid, citric acid, proline, phenylalanine, threonine, mannitol, leucine, serine, creatine, alanine, and 4-hydroxyproline, which were more abundant in the CV-AE group. Conversely, myristic acid, oxalic acid, arabitol, 4-deoxy rithronic acid, ribose, and elaidic acid were less represented in the CV-AE group. Conclusions: CML patients with CV-AEs show a different metabolic profile, suggesting probable mechanisms of endothelial damage.

AbstractMutations in the Bcr-Abl kinase domain may cause, or contribute to, resistance to tyrosine kinase inhibitors (TKIs) in chronic myeloid leukemia patients. Recommendations aimed to rationalize the use of BCR-ABL mutation testing in chronic myeloid leukemia have been compiled by a panel of experts appointed by the European LeukemiaNet (ELN) and European Treatment and Outcome Study and are here reported. Based on a critical review of the literature and, whenever necessary, on panelists' experience, key issues were identified and discussed concerning: (1) when to perform mutation analysis, (2) how to perform it, and (3) how to translate results into clinical practice. In chronic phase patients receiving imatinib first-line, mutation analysis is recommended only in case of failure or suboptimal response according to the ELN criteria. In imatinib-resistant patients receiving an alternative TKI, mutation analysis is recommended in case of hematologic or cytogenetic failure as provisionally defined by the ELN. The recommended methodology is direct sequencing, although it may be preceded by screening with other techniques, such as denaturing-high performance liquid chromatography. In all the cases outlined within this abstract, a positive result is an indication for therapeutic change. Some specific mutations weigh on TKI selection.

Background. Cardiovascular adverse events (CV-AE) are emerging complications in chronic myeloid leukemia (CML) patients treated with second and third generation tyrosine kinase inhibitors (TKIs). Despite the importance of CV risk factors,predictive CV-AE biomarkers are still lacking. Further understanding of the molecular pathways underlying CV-AE may promote novel strategies to prevent its initiation prior to clinical disease. In this scenario, the use of a novel tool such as metabolomics may be useful for the identification of new metabolic pathways related to CV-AE. Metabolites are the output of cellular metabolism, accounting for expression and activity of genes, transcripts, and proteins, and offering unique insights into small molecule regulation. For the first time we evaluated the correlation between CV-AE and metabolomic profile in CML patients treated with TKIs. Methods. We considered 39 adult CP-CML patients (mean age 49, range 24-70), without comorbidity at baseline, consecutively diagnosed and treated with imatinib, dasatinib nilotinib and ponatinib, at the Haematology Unit of "Businco Hospital", Cagliari, Italy. All patients underwent a metabolomic profile detection, after CV-AE or during follow-up, and were stratified in 2 groups (with or without CV-AE). Plasma samples were collected and acquired chromatogram was analysed by means of the free software AMDIS (Automated Mass Spectral Deconvolution and Identification System; http://chemdata.nist.gov/mass-spc/amdis) that identified each peak by comparison of the relative mass spectra and the retention times with those stored in an in-house made library comprising 255 metabolites. Data were investigated by applying the supervised multivariate statistical approach OPLS-DA (Orthogonal partial least square discriminant analysis) (SIMCA, version 13.0, Umetrics, Umea, Sweden). Results. The mean follow-up since CML diagnosis was 3.7 years (range 0.9-5); 22 (56.4%) patients were treated frontline, while 17 (43.5%) underwent second or subsequent TKI lines of treatments. The reason for switching was inefficacy in 15.3% and intolerance in 28.2%. At CV-AE or last follow-up 16 (41%) patients were treated with imatinib, 8 (20.5%) with dasatinib, 14 (35.8%) with nilotinib and 1 patient with ponatinib (2.7%). Overall, 17 CV-AE were recorded: 7 cases of hypercholesterolemia, 5 pleural or pericardial effusions, one episode of hypertension and 4 cardiac events (atrial fibrillation,ST-segment elevation myocardial infarction, reduction of cardiac ejection fraction and dissecting aneurysm of the aorta); 7 CV-AE were graded as 3 according to the common toxicity criteria and one patient died from dissecting aneurysm of the aorta). The 60-month cumulative CV-AE incidence was 54.4±9.1%. The mean time between the start of the treatment and the occurrence of a CV-AE was 44.4 months (range 19-60). OPLS-DA showed that patient's samples were clearly separated into 2 groups indicating that CV-AE patients (blue dots) presented a markedly distinct metabolic profile compared with patients without CV-AE (green dots); (figure 1). The parameters of the model were R2Y = 0.76 and Q2 = 0.44. To validate the OPLS-DA model, a permutation was performed resulting statistically significant (p=0,002). The main discriminant metabolites were tyrosine, lysine, ornithine, glutamic acid, 2-piperdincarboxylic acid, proline, citric acid, phenylalanine, mannitol, threonine, leucine, creatine, serine, 4-hydroxyproline, and alanine (more represented in CV-AE group); while unknown 204, myristic acid, arabitol, oxalic acid, 4-deoxyrithronic acid, elaidic acid and ribose resulted less expressed in CV-AE group. Conclusions. This exploratory study showed different metabolomic profile of CML patients with CV-AE underwent TKI treatment, suggesting possible mechanisms of endothelial damage mediated by the accumulation of metabolites. Tyrosine, highly expressed in the CV-AE CML group, is a reliable marker of oxidative stress in various acute and chronic diseases.Metabolomics research has considerable potential for translating the metabolic fingerprint into personalized therapeutic strategies. These preliminary data should be confirmed in prospective clinical trials. Figure 1 Disclosures No relevant conflicts of interest to declare.

Introduction. BCR-ABL tyrosine kinase inhibitors are currently used to successfully treat chronic myeloid leukemia (CML). Drug therapy is carried out in a continuous daily mode throughout the patient’s life. Treatment with this group of drugs is associated with specific dermatological adverse events (dAE), which can lead to a change in the regimen of effective, vital therapy for CML patients.Purpose. To study the characteristics of dermatological adverse events, the severity and influence on the quality of life of BCR-ABL tyrosine kinase inhibitors.Patients and methods. The observational study included 93 patients. The clinical manifestations of dAE, their severity were evaluated, their photographs and pathomorphological studies of skin biopsy samples were performed, cases of dose reduction or drug withdrawal due to dAE were recorded. The quality of life of patients with dAE was determined based on the assessment of the dermatological index of quality of life.Results. Imatinib therapy was accompanied by a maculopapular rash in 43.3 % of patients, nilotinib caused follicular keratosis in 12.9 % of patients. In 3.2 % of patients, dasatinib caused hyperpigmentation, in 2.2 % of patients lichenoid rashes of the II degree occurred during treatment with bosutinib. Ponatinib treatment was followed by dAE in 9.7 % of patients. All dAE have an impact on the quality of life of patients, but the maculopapular rash and dyskeratotic changes are most pronounced. In a pathomorphological study, these dAE have specific features corresponding to immuno-mediated dermatitis.Conclusions. The most frequent and pronounced dAE that significantly affect the quality of life of patients with CML are a maculopapular rash and dyskeratotic skin changes: psoriasiform and lichenoid dermatitis. Clinical and pathomorphological characteristics of skin reactions make it possible in the future to determine effective methods of supportive therapy for dAE.
