Combination of imatinib with chemotherapy has been recently reported as very promising in patients with Ph+ ALL. During 2004 and 2005, 45 patients with newly-diagnosed Ph+ ALL were treated in the GRAAPH-2003 study in which imatinib was started with HAM consolidation in good early responders (cortico- and chemo-sensitive ALL) or earlier during the induction course in combination with dexamethasone and vincristine in poor early responders (cortico- and/or chemo-resistant ALL). Imatinib was then continuously administered until stem cell transplantation (SCT). Overall, complete remission (CR) and BCR-ABL RQ-PCR negativity rates were 96% and 29%, respectively. All the 22 CR patients (100%) with a donor actually received allogeneic SCT in first CR. At 18 months, estimated cumulative incidence of relapse, disease-free and overall survival were 30%, 51%, and 65%, respectively. These three endpoints compared very favorably with results obtained in the pre-imatinib LALA-94 trial. This study confirms the value of the combined approach and encourages prospective trials to define the optimal chemotherapy which has to be combined with imatinib and carefully re-evaluate the place of allogeneic SCT in this new context.
