Acute lymphoblastic leukemia (ALL) is the most common malignant disease in childhood. Survival rates exceed 90% in children and 75% in adults (aged 18-45 years). During the induction period Asparaginase is an indispensable part of the multiagent treatment, but is often associated with hypersensitivity, either with clinical allergy or silent inactivation. In both cases, Asparaginase is inactivated. It is well known that truncation of Asparaginase treatment due to inactivation reduces survival. To approach understanding Asparaginase dynamics and hypersensitivity in ALL patients it is important to examine the pharmacokinetics of Asparaginase. The aim of this study is to identify serological parameters for prediction of hypersensitivity reaction after the first doses of PEG-Asparaginase given intravenously on the ALLTogether protocol.
