Side effects of L-asparaginase during therapies for remission induction and maintenance in children with acute lymphocytic leukemia / 中国实验血液学杂志

ABSTRACT

This study was purposed to investigate the possible side effects of L-asparaginase (L-ASP) in the treatment of patients with acute lymphoblastic leukemia (ALL) and to explore the correlation of these side effects at different therapeutic stages by means of retrospective analysis, so as to reduce the incidence of side effects and improve the safety of chemotherapy and the long-term survival of patients. The probability and severity of side effects related to use of L-ASP in 38 cases of ALL during remission induction therapy (VDLDex regimen) and 40 cases of ALL during maintenance intensive therapy (VMLDex regimen) were compared. The results showed that allergic response, diabetes and drug-induced liver disease happened more frequently during maintenance therapy than during remission induction therapy, while defibrination, abnormal hemagglutinin, acute pancreatitis, hypoproteinemia, gastrointestinal reaction and infectious shock were observed more during remission induction therapy than those at maintenance therapy. In conclusion, the L-ASP showed some side effects especially for the patients during the remission induction therapy which should be paid enough attention. The regular and comprehensive monitoring can effectively reduce and avoid the side effects of L-ASP, to improve the safety of chemotherapy.
