Abstract:

Acute myeloid leukemia accounts for about 15%-20% of childhood leukemia, and nearly 40% of pediatric patients still relapse after standard chemotherapy. Allogeneic hematopoietic stem cell transplantation is a powerful means to prevent its recurrence. However, some patients still relapse, and the 2-year survival rate of these patients is less than 20%. Some patients with relapse cannot tolerate or are insensitive to conventional chemotherapy. Recurrence is the main cause of death after transplantation. The prevention of relapse after transplantation ought to start before transplantation, optimize each part of the transplantation chain, and strictly follow the follow-up monitoring. In recent years, new molecular targeted drugs, new immunotherapy and CRISPR genome-edited hematopoietic stem cell therapy have also provided more treatment strategies for pediatric patients with AML relapse after transplantation. According to the procedure of transplantation chain, this paper summarized the preventive measures of each link and the treatment options of post-transplantation recurrence, in order to provide the direction and strategy for the clinic.
