Abstract:
OBJECTIVEThe Chinese Children's Leukemia Group (CCLG)-acute lymphoblastic leukemia (ALL) 08 protocol for childhood ALL was established in 2008. This study aims to evaluate the drug-related toxicities of CCLG-ALL 08 protocol in the treatment of childhood ALL.
METHODSA total of 114 children with newly diagnosed ALL were treated with the CCLG-ALL 08 protocol. The protocol was divided into five phases: remission induction (VDLD), early reinforcement (CAM), consolidation therapy, delayed reinforcement (DIa & DIb) and maintenance treatment. Drug-related toxicities in each phase were evaluated according to the Common Terminology Criteria for Adverse Events version 4.0.
RESULTSToxicities were more frequent in phase VDLD than other treatment phases, including hepatotoxicity (87.7%), dental ulcer (20.2%), hyperglycemia (20.2%), prolonged activated partial thromboplastin time (21.1%) and decreased fibrinogen (34.2%), with the incidence rates of severe adverse events at 7%, 0, 1.3%, 0.8% and 2.7% respectively. The incidence of allergic reaction to L-ASP was significantly higher in phase DIa than in phase VDLD (28.0% vs 7.9%; P<0.01), and there were no longer any allergic reactions in 15 patients who received continuing treatment with pegaspargase instead. There was no severe arrhythmia, myocardial ischemia, decreased left ventricular function, osteonecrosis, myopathy, organ failure or treatment-related mortality.
CONCLUSIONSThe drug-related toxicities of CCLG-ALL 08 protocol are common in phase VDLD, but they are mild and reversible. There is no treatment-related mortality. The CCLG-ALL 08 protocol for childhood ALL is safe.
