Brief Summary

Leukemia is one of the common malignant tumors that threaten human health. Although the efficacy of AML treatment has improved significantly in recent years, it remains one of the major diseases threatening human health. Current research on AML treatment mainly has two directions. One is the addition of new targeted therapy drugs, and the other research dire...

Detailed Description

This study is a prospective, randomized, controlled phase III clinical trial that plans to enroll adult patients with AML who meet the WHO (2022) or ICC criteria for eligibility for intensive chemotherapy with RUNX1-RUNX1 fusion. For patients who meet the inclusion criteria and do not meet any exclusion criteria, they will be randomly assigned to either the ...
