Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Patients enrolled from each center according to confirmed criteria specified in cooperative scheme are recieved induction and consolidation chemotherapy with microtransplantation . Observe the remission rate and 2-year disease-free survival (DFS) and overall survival(OS) rate.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Microtransplantation, which combines chemotherapy with adoptive infusion of granulocyte colony stimulating factor (G-CSF) mobilized HLA-mismatched peripheral blood stem cells (GPBSC). Data from more than 70 elderly AML patients who received microtransplantation in Beijing showed that the remission rate and 2-year disease-free survival (DFS) reach 75-82% and 32-39% respectively, and microchimerisms (donor cells\<1%) were detected without GVHD. The results have been clinically validated in several other centers in China, United States and Australia.

In this study, azacytidine, decitabine, BCL / 2 inhibitor and other drugs combined with micro transplantation were used in elderly AML in order to improve the curative effect.

MST for unfit

Induction chemotherapy can use azacytidine combined with low-dose cytarabine, or azacytidine combined with BCL / 2 inhibitor, and infuse modified peripheral blood hematopoietic stem cells after chemotherapy.

Consolidation chemotherapy used azacytidine combined with low-dose cytarabine. After chemotherapy, modified peripheral blood hematopoietic stem cells were infused and repeated for 3 courses.
