Abstract

There are few therapeutic options for patients with T-cell acute lymphoblastic leukemia (T-ALL) who have recurrent disease after initial matched sibling hematopoietic stem cell transplantation. While a second hematopoietic stem cell transplant (HSCT) from a haploidentical donor offers the conceptual possibility of greater graft versus leukemia effect, there is minimal literature to describe the efficacy of this approach in recurrent pediatric T-ALL. We present the case of a now 9-year-old female in whom second haploidentical HSCT, followed by successive donor lymphocyte infusions in response to minimal residual disease reemergence, has led to 3+ years of ongoing disease control without graft versus host disease and excellent quality of life.
