PURPOSE: Modern ALL therapy aims to reduce toxicity, while maintaining and improving the current high cure rates. Acute and late sequelae of anthracyclines are of major concern. The AIEOP-BFM ALL 2009 trial aimed to clarify the need for anthracyclines in low-risk patients.
PATIENTS AND METHODS: After 2 weeks of induction therapy, which included two daunorubicin (DNR) doses once weekly (30 mg/m2 each) as part of a 4-drug therapy, patients age 1-17 years with newly diagnosed non-high-risk B-ALL either positive for ETV6::RUNX1 or with rapid treatment response, as assessed by induction day-15 evaluation, were randomly assigned to receive either two additional doses of DNR (control arm [CA]) or no further DNR during induction (experimental arm [EA]). Patients treated as randomly assigned were included in the primary analysis on noninferiority in event-free survival (EFS). Adverse reactions of special interest (ARSI) were analyzed in the as-treated population.
RESULTS: Of 6,136 patients enrolled in AIEOP-BFM ALL 2009, 2,514 patients (41.0%) were eligible for this random assignment, with 82.7% actually randomly assigned (EA: n = 1,040 and CA: n = 1,039). The 5-year EFS was 92.5% (SE 0.8%) in CA and 92.2% (SE 0.9%) in EA. Accordingly, cumulative incidence of relapse was 5.8% (SE 0.7%) and 5.7% (SE 0.7%), and overall survival was 97.6% (SE 0.5%) and 97.4% (SE 0.5%) in CA and EA, respectively. Life-threatening and fatal ARSI were similar in the two arms, but there was a three times lower incidence of invasive fungal infections in the EA (0.5% v 1.5%, P = .02).
CONCLUSION: A reduced DNR dose during induction did not compromise the outcome of patients with favorable prognostic factors but did diminish infectious toxicity indicated by the lower rate of invasive fungal infections.
