This study used Korean national data to investigate the relationship between treatment patterns and outcomes in Korean adolescent and young-adult (AYA) acute lymphoblastic leukaemia (ALL) patients. Chemotherapy incorporating L-asparaginase was considered paediatric-inspired (PI), as opposed to adult protocols. In total, 65·3% of patients received PI therapy. Five-year overall survival (OS) of PI-treated patients outperformed adult protocols (63·1% vs. 40·4%; P < 0·0001); this trend was maintained within various age subgroups. Younger age, L-asparaginase therapy, and radiotherapy corresponded with superior OS by multivariable analysis. OS tends to improve with PI protocols that include L-asparaginase in AYA ALL, suggesting that therapy protocol is critical in the treatment performance of this group.
