Outcome and Prognostic Factors of Haploidentical Allogeneic Hematopoietic Stem Cell Transplantation in Pediatric Relapsed or Refractory <i>ETV6/RUNX1</i>-Positive Acute Lymphoblastic Leukemia

The role of haploidentical allogeneic hematopoietic stem cell transplantation (haplo-HSCT) in pediatric patients with relapsed or refractory (R/R) ETV6/RUNX1-positive acute lymphoblastic leukemia (ALL) is unclear. This study aimed to identify prognostic factors and explore the role of haplo-HSCT in the treatment of ETV6/RUNX1-positive ALL.
