Herein we present a rare case of two brothers diagnosed with CML four years apart. Importantly, our case of CML occurrence among siblings is the fifth one reported and the second one investigated by both, conventional cytogenetics and RT-PCR analysis. Moreover, although Ph chromosome was detected in both our patients, RT-PCR revealed the presence of two different BCR-ABL transcripts. Finally, both our patients have been followed for a long period of time offering thus the opportunity to observe the differences in the clinical course.

Background: Imatinib is the treatment of elderly or frail patients with chronic myeloid leukemia (CML). Trough levels of around 1000 ng/ml are considered as the target exposure.
Objectives: We searched for baseline parameters associated with imatinib pharmacokinetics, and studied the clinical impact of subsequent adaptive dosing.

Objective: To compare the efficacy and safety of flumatinib (FM) and imatinib (IM) as first-line treatment in newly-diagnosed patients with chronic myeloid leukemia in chronic phase (CML-CP) in real world.
Methods: A total of 84 newly-diagnosed CP-CML patients in our center from December 2019 to December 2022 were retrospectively analyzed. Among them, 32 cases received FM as first-line treatment, and 52 cases received IM.

The coexistence of three or more transcripts in one patient with chronic myeloid leukemia (CML) is rarely reported. Thus, the disease progression and drug response are still unknown. This case report aimed to explore the drug response of CML with variant transcripts and to enrich the clinical treatment of rare types of CML.

Introduction: The emergence of mutations in the BCR::ABL1 kinase domain (KD) impairs imatinib mesylate (IM) binding capacity, thus contributing to IM resistance. Identification of these mutations is important for treatment decisions and precision medicine in chronic myeloid leukaemia (CML) patients. Our study aims to determine the frequency of BCR::ABL1 KD mutations in CML patients with IM resistance.

Purpose: The treatment landscape for chronic myeloid leukemia (CML) has been revolutionized by the introduction of imatinib, a tyrosine kinase inhibitor, which has transformed the disease from a fatal condition into a manageable chronic illness for a substantial number of patients. Despite this, some individuals do not respond adequately to the treatment, and others may experience disease progression even with continued therapy. This study examined how CYP2C8*3 (G416A; rs11572080) and ABCG2 C421A (rs2231142) single nucleotide polymorphisms (SNPs) affect the plasma trough concentration and therapeutic response of imatinib in Egyptian CML patients.
