Abstract:
Objective To evaluate the effect of haploidentical lymphocyte infusion on refractory and relapse acute leukemia. Methods The haploidentical donor lymphocyte infusion was used to treat for relapse acute myeloid leukemia 3 patients (M2 2 eases, M4 lcase), one relapse acute lymphocyte leukemia from April 2006 to October 2007. Four cases who had accepted secondly regimens were ineffective,after relapse. Collecting donor lymphocytes, parents children as donor supply in 3 cases, mother as donor supply one case. Before donor lymphocyte infusion patients received chemotherapy of different regimens. Donor haploidentical iymphocytes irradiated by 6-8 Gy radial were infused when patients white cell count was at the lowest after the chemotherapy. The average of infusion cells was 2.3 (1.4-3.1)×108/kg. Results One patient acquired complete remission and two patients were effective in three relapse acute myeloid leukemia. It was ineffective in relapse acute lymphocyte leukemia. No transfusion related graft versus host disease was observed. One patient has had herpes zoster virus infection. Conclusion Haploidentical donor lymphocyte infusion with chemotherapy are effective for refractory and relapse in acute myeloid leukemia, but the infused cell quantity and irradiated dosage must be further discussed.
