High Expression of NTRK1 in ETV6::RUNX1 Positive Acute Lymphoblastic Leukaemia Drives Factor Independence and Sensitivity to Larotrectinib

ETV6::RUNX1 is one of the most common recurrent genomic abnormalities in acute lymphoblastic leukaemia (ALL) and is associated with a good prognosis. High expression of NTRK1, encoding tropomyosin receptor kinase A (TrkA), confers a poor prognosis in other malignancies and may contribute to therapy resistance in patients with ETV6::RUNX1 B-ALL.
