Brief Summary

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

In this observational single-center cohort study, metagenomic Next-Generation Sequencing (mNGS) will be used to investigate the features and changes of gut microbiota in acute myeloid leukemia (AML) patients during the treatment of two different induction therapy regimens \[standard intensive chemotherapy (7+3) or bcl-2 inhibitor-based targeted therapy\].

Detailed Description

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

Infections remain one of the major complications during induction therapy of acute myelocytic leukemia (AML). Previous studies have shown that the variation of gut microbiota was an effective predictor for infection development of AML during induction therapy. A growing number of patients with AML received bcl-2 inhibitor-based targeted induction therapy. The investigators assume that there are different effects of bcl-2 inhibitor-based induction therapy on gut microbiota compared with standard intensive chemotherapy (7+3 regimen). Metagenomic Next-Generation Sequencing (mNGS) will be used to perform the investigation of gut microbiota in AML receiving two different induction therapies. And the relationships of gut microbiota with infection complication will be analyzed.

Standard intensive chemotherapy

Patients with acute myeloid leukemia in this cohort will receive standard induction chemotherapy that combines seven days of cytarabine and three days of anthracycline (7+3 regimen).
