Summary
Brief summary (as posted)
Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is the main method potentially curing adult B-ALL, but the high treatment-related mortality (NRM) affects overall survival (OS). Autologous stem cell transplantation (auto-HSCT) can significantly reduce NRM but has a higher relapse rate. Studies have confirmed that achieving MRD negativity before Auto-HSCT can effectively reduce post-transplant relapse, achieving similar efficacy to allo-HSCT. The efficacy of blinatumomab in clearing MRD has been confirmed. Therefore, using blinatumomab combined with Auto-HSCT for B-ALL patients seems to make it possible to achieve benefits in leukemia free survival（LFS） and OS. The investigators first conducted blinatumomab and auto-HSCT "sandwich " strategy as consolidation therapy in patients with B-ALL. The main Purpose of this study was to observe the safety and efficacy of this new strategy.
