AbstractObjectives: High body mass index (BMI) is associated with poorer survival in childhood acute lymphoblastic leukemia (ALL), but the actual impact on the risk of relapse still needs to be clarified. We evaluated the impact of BMI at diagnosis on the risk of relapse in children with ALL treated according to Nordic Society of Paediatric Haematology and Oncology (NOPHO) protocols. Method: In a multicenter study, we collected data on BMI at diagnosis and outcome of 2558 children aged 2.0‐17.9 years diagnosed between 1992 and 2016. Patients were divided into four groups according to International Obesity Task Force (IOTF) childhood BMI cut‐offs: underweight, <17; healthy weight, 17‐25; overweight, 25‐30; and obese, ≥30 kg/m². Results: In Cox multivariate regression analyses, an increased risk of relapse was observed in children aged 10‐17.9 years with unhealthy BMI at diagnosis (underweight hazard ratio HR: 2.90 [95% confidence interval: 1.24‐6.78], P = .01; overweight, HR: 1.95 [1.11‐3.43], P = .02, and obese HR: 4.32 [95% 2.08‐8.97], P < .001), compared to children with healthy weight. BMI had no impact on relapse in children under 10 years of age. Conclusion: High BMI, and especially obesity at diagnosis, is an independent adverse prognostic factor for relapse in older children with ALL. see all
