1In three cases only a remission in peripheral blood was documented between the salvage therapy and the allogeneic HSCT and a bone marrow puncture was performed after the a HSCT;
2This patient received three cycles of clofarabine, cyclophosphamide and etoposide afterwards and was transplanted subsequently;
3This patient received one cycle of clofarabine, cyclophosphamide, etoposide and cytarabine afterwards and was transplanted subsequently; *This patient developed multiple chloromas, which were irradiated. In addition, he received 4 cycles of blinatumomab followed by another stem cell transplantion.
AHSCT: Allogeneic Hematopoietic Stem Cell Transplantation; ALL: Acute Lymphoblastic Leukemia; AML: Acute Myeloid Leukemia; BM: Bone Marrow; CR: Complete Remission; EFS: Event Free Survival; F: Female; M: Male; Mel/Ara-C: Melphalan/Cytarabine; MMFD: Mismatched Family Donor; MRD: Minimal Residual Disease; MUD: Matched Unrelated Donor; NA: Not Available; OS: Overall Survival; TF: Treatment Failure
