Patients with NOTCH1 mutations benefit more from BTK inhibitor treatment than from immunochemotherapy for chronic lymphocytic leukemia (CLL).
CLL is a common hematologic malignancy, and treatment decisions depend on molecular features, including TP53 and IGHV mutational status.
Research suggests that NOTCH1 mutations may serve as a biomarker for selecting Bruton tyrosine kinase inhibitors (BTKi) therapy.
NOTCH1 is one of the most frequently mutated genes in CLL, present in approximately 20% of newly diagnosed cases.
A bicentric retrospective analysis from 2 French tertiary care centers supports the importance of NOTCH1 mutations in guiding therapy.
