Prevention and treatment of high-risk acute myeloid leukemia recurrence after allogeneic hematopoietic stem cell transplantation

Acute myeloid leukemia (AML) is a group of highly-heterogeneous clonal diseases. Chemotherapy and hematopoietic stem cell transplantation are considered as effective treatment for AML. For high-risk AML patients, allogeneic hematopoietic stem cell transplantation is an effective therapeutic option. However, some AML patients may still face the problem of disease recurrence after hematopoietic stem cell transplantation. A majority of recurrent patients cannot be effectively treated by chemotherapy or secondary transplantation, which is the main cause of death after allogeneic hematopoietic stem cell transplantation. Therefore, it is of significance to strengthen follow-up of AML patients after allogeneic hematopoietic stem cell transplantation and implement appropriate measures to prevent postoperative recurrence. In this article, the monitoring, drug prevention and cell therapy of recurrence after allogeneic hematopoietic stem cell transplantation in high-risk AML patients were reviewed, aiming to provide reference for improving clinical prognosis of high-risk AML patients undergoing allogeneic hematopoietic stem cell transplantation.
