We identified 9 of 386 patients with T-ALL (2.3%) with subclonal and clonal TP53/KRAS variants at initial diagnosis, who exhibited an unfavorable treatment response. Of 9 HR patients, 8 relapsed and died (patient number 41, 110, 126, 47, 33, 73, 77 and 35).
AA, amino acid; CCR, continuous complete remission; HR, high risk; n.a., not available; n.q., not quantifiable; TP, time point.
