[Sorafenib combined with chemotherapy and donor lymphocyte infusion as salvage therapy in patients with FLT3-positive acute myeloid leukemia relapse after allogeneic hematopoietic stem cell transplantation].

ABSTRACT

To explore the efficacy of sorafenib combined with chemotherapy and donor lymphocyte infusion (DLI) in patients with FLT3-positive acute myeloid leukemia (AML) relapsed after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Of the 14 patients relapsed after allo-HSCT, 9 achieved complete remission after salvage therapy of sorafenib combined with chemotherapy and DLI, 6 with complete molecular remission, 2 with partial remission, and 3 with no response. With a median follow up of 220 (range, 30-1 782) days after post-transplantation relapse, 7 patients were still alive and 7 died. Salvage therapy of sorafenib combined with chemotherapy and DLI shows a decent therapeutic effect for FLT3-positive AML relapsed after allo-HSCT.
