Early T-cell precursor-ALL (ETP-ALL) is a subtype of T-ALL with a poor prognosis in children. We analyzed ETP-ALL compared to conventional T-ALL/LBL in both adults and children to determine any differences in clinical outcomes, based on the following parameters: induction failure, relapse, and survival. Patients with ETP-ALL have a higher risk of relapse, especially in children (in all patients, HR=4.08, p=0.127, and children, HR=11.63, p=0.025). ETP-ALL seems to have an increased risk of adverse outcomes, particularly in children. Larger studies are needed to better determine the prognosis of this subtype of T-ALL.
