Bortezomib Combined With DAG Regimen in the Treatment of Refractory/Relapsed AML

Summary

In recent years, the efficacy of AML has been greatly improved, which is mainly due to the following aspects: the development of individualized treatment strategies based on genetic prognosis stratification, the application of high-dose cytarabine-containing induction and consolidation regimens , the choice of allogeneic or autologous hematopoietic stem cell transplantation, etc. However, 20%-30% of young patients and 40%-50% of elderly patients will relapse again, and 20%-40% of patients cannot be relieved after standard induction regimens, that is, relapsed and refractory AML. The re-induction remission rate is low, the survival period is short, and the prognosis is extremely poor. There is still a lack of standard treatment options. Although a small number of patients can benefit from allogeneic hematopoietic stem cell transplantation (allo-HSCT), most patients lack suitable donors. The choice of high-dose chemotherapy is a salvage treatment option, but treatment-related hematological or non-hematological toxicities and high lethality make the option controversial, especially for the elderly. The development of new low-toxic targeted drugs is a future trend, and the design of new efficient and safe chemotherapy regimens is also a way of thinking. This study designed a prospective single-center clinical randomized controlled study plan, that is, the use of bortezomib (1.3mg/m2, d1, 4, 8, 11) combined with DAG regimen in the treatment of refractory/relapsed AML, to evaluate the clinical efficacy (complete remission rate , total effective rate, 2-year progression-free survival rate and 2-year overall survival rate), and observe how safe the new program is. The results of the research will make it possible to design a high-efficiency, low-toxicity and high-feasibility chemotherapy regimen for refractory/relapsed patients, and guide the clinical treatment of relapsed/refractory acute leukemia.
