- Abstract
Evidence regarding the efficacy of gemtuzumab ozogamicin (GO) addition to standard induction chemotherapy in newly diagnosed acute myeloid leukaemia (AML) is conflicting. This systematic review aimed to identify and summarize all evidence regarding the benefits and harms of adding GO to conventional chemotherapy for induction treatment of AML. A comprehensive literature search of two databases (PUBMED and Cochrane) from inception up to November 22, 2012, and 4 years of proceedings from four major haematology/oncology conferences was undertaken. Endpoints included benefits (complete remission, relapse-free, event-free, and overall survival), and harms (early mortality and incidence of hepatic veno-occlusive disease/sinusoidal obstructive syndrome). Seven trials (3942 patients) met all inclusion criteria. Addition of GO showed improved relapse-free [Hazard Ratio (HR) = 0·84 (95% confidence interval (CI) 0·71-0·99)] and event-free survival [HR = 0·59 (95%CI 0·48-0·74)] but not overall survival [HR = 0·95 (95%CI 0·83-1·08)]. Addition of GO resulted in higher rate of early mortality [Risk Ratio = 1·60 (95%CI 1·07-2·39)]. Improved overall survival was observed in studies using a lower cumulative GO dose (<6 mg/m(2) ) [HR = 0·89 (95%CI 0·81-0·99)]. Addition of GO to conventional chemotherapy as induction therapy may improve relapse-free and event-free survival, but does not impact overall survival and significantly increases early mortality in AML., (© 2013 John Wiley & Sons Ltd.)
