γδT cells belong to the innate immune system and have a powerful anti-tumor effect. Leukemia patients transplanted with allogeneic hematopoietic stem cells have an important role in controlling leukemia recurrence. Although adoptive immunotherapy using in vitro expanded γδT cells has achieved significant results in patients with solid tumors, infusion of donor γδT cells in leukemia patients undergoing allogeneic hematopoietic stem cell transplantation to prevent leukemia recurrence has not been reported. . This clinical study intends to initially observe the safety and effectiveness of donor γδT cell infusion to prevent recurrence/refractory leukemia salvage allogeneic hematopoietic stem cell transplantation to further improve the transplantation effect of these patients
