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 direction is to enhance the intensity of AML chemotherapy, including the use of large doses of anthracycline drugs or the use of high-dose cytarabine treatment. Since the 1990s, induction remission has been achieved by using anthracyclines in combination with high-dose cytarabine. The ECOG (Eastern Cooperative Oncology Group) contends that high-dose induction chemotherapy fails to enhance the bone marrow remission rate but elevates the chemotherapy-related mortality rate. Bradstock and the Australian Group also noted that although it does not increase the bone marrow remission rate, it can result in longer survival time and disease-free survival time. The clinical study from EORTC-GIMEMA AML-12 discovered that AML patients under the age of 45 could benefit from induction therapy incorporating high-dose cytarabine. In our previous randomized controlled clinical trials, it was found that the HAD and DA regimens containing intermediate-dose cytarabine could enhance the complete remission rate and improve the overall survival of adult AML. However, the degree of benefit varies among different AML subgroups. The abnormalities of RUNX1-RUNX1T1 and CBFβ-MYH11 respectively involve a subunit of CBF (core binding factor), thus the two are collectively called CBF leukemia. Previous retrospective studies show that this type of leukemia benefits from intensified treatment regimens such as FLAG. However, at present, there is a lack of prospective randomized controlled clinical studies to confirm this. Therefore, in this study, we intend to further verify through a prospective randomized controlled clinical trial whether the induction treatment regimen containing intermediate-dose cytarabine can improve the long-term efficacy of adult RUNX1-RUNX1T1 acute myeloid leukemia.

Interventions

DRUG

cytarabine

Cytarabine combined with daunorubicin was used for induction therapy. According to the different doses of cytarabine, it was divided into standard dose group and intermediate dose group.In addition, high doses of cytarabine are also used for post-remission treatment.

Inclusion Criteria: 1. AML conforming to WHO (2022) or ICC standards 2. Possessing the RUNX1::RUNX1T1 fusion gene 3. Age ranging from 14 to 60 years old, regardless of gender. 4. The performance status assessment of the Eastern Cooperative Oncology Group (ECOG-PS) being 0 - 2. 5. Meeting the requirements of the following laboratory examination indicators (conducted within 7 days before treatment): 1\) Total bilirubin ≤ 1.5 times the upper limit of the normal value for the same age group; 2) AST and ALT ≤ 2.5 times the upper limit of the normal value for the same age group; 3) Serum creatinine \< 2 times the upper limit of the normal value for the same age group; 4) Cardiac enzymes \< 2 times the upper limit of the normal value for the same age group; 5) The cardiac ejection fraction determined by echocardiography (ECHO) \> 50%. An informed consent form must be signed before the commencement of all specific research procedures, either by the patient themselves or their immediate relatives.

Exclusion Criteria: 1. Acute promyelocytic leukemia accompanied by PML-RARA fusion gene. 2. Acute myeloid leukemia featuring BCR-ABL fusion gene. 3. Patients undergoing retreatment (but can receive cytoreductive therapy with hydroxyurea and cytarabine). 4. Individuals concurrently having malignant tumors in other organs (requiring treatment). 5. Active cardiac disorders, defined as one or more of the following: 1\) A history of uncontrolled or symptomatic angina pectoris; 2) Myocardial infarction less than 6 months from study enrollment; 3) A history of significant arrhythmia requiring medication or presenting with severe clinical symptoms; 4) Uncontrolled or symptomatic congestive heart failure (\> NYHA Class 2) 6\. Severe infectious diseases (untreated tuberculosis, pulmonary aspergillosis). 7\. Individuals deemed ineligible for enrollment by the investigator.
