Recently, Bethge et al. [26] reported results of haploidentical transplantation on 29 adult patients with hematologic malignancies (AML = 16, ALL = 7, NHL = 3, MM = 2, CML = 1) who received CD3/CD19 depleted grafts following a RIC regimen consisting of fludarabine, thiotepa, melphalan, and OKT-3. Here, CD19 is linked to hematologic disorder.
