简要总结

A prospective, single-center, cohort study to allow collecting observations of patients receiving induction chemotherapy for primary Acute Myeloid Leukemia (AML), collecting biological samples(including fecal samples for microbiota analyses, and metagenomic profiling in blood samples) and clinical outcomes (notably the occurrence of neutropenic enterocolitis), with a nested case-control analysis comparing patients with or without neutropenic enterocolitis
