Several studies reported improved outcomes of adolescents and young adults (AYA) with acute lymphoblastic leukemia (ALL) treated with pediatric-based ALL regimens. This prompted the prospective investigation of a pediatric Augmented Berlin–Frankfurt–Münster (ABFM) regimen, and its comparison with hyper-fractionated cyclophosphamide, vincristine, Adriamycin, and dexamethasone (hyper-CVAD) in AYA patients. One hundred and six AYA patients (median age 22 years) with Philadelphia chromosome- (Ph) negative ALL received ABFM from October 2006 through March 2014. Their outcome was compared to 102 AYA patients (median age 27 years), treated with hyper-CVAD at our institution. The complete remission (CR) rate was 93% with ABFM and 98% with hyper-CVAD. The 5-year complete remission duration (CRD) were 53 and 55%, respectively (P = 0.98). The 5-year overall survival (OS) rates were 60 and 60%, respectively. The MRD status on Day 29 and Day 84 of therapy was predictive of long-term outcomes on both ABFM and hyper-CVAD. Severe regimen toxicities with ABFM included hepatotoxicity in 41%, pancreatitis in 11%, osteonecrosis in 9%, and thrombosis in 19%. Myelosuppression-associated complications were most significant with hyper-CVAD. In summary, ABFM and hyper-CVAD resulted in similar efficacy outcomes, but were associated with different toxicity profiles, asparaginase-related with ABFM and myelosuppression-related with hyper-CVAD.
