Intervention / Treatment
Detailed Description
20% of children with ALL still fails to be cured. The ALL-2008 protocol is a treatment and research protocol that aims to improve the overall outcome of Nordic children and adolescents with ALL in comparison with the ALL-2000 protocol and previous NOPHO protocols.
The specific and primary objectives of the randomised study is:
To increase the fraction of patients, who become MRD-negative during consolidation for the non-HR ALL group through individualised intensification of the 6MP-dosage days 30-85. We will additionally measure EFS and toxicity as secondary end points of effect.
