Risk Stratification Value of Deep NGS-MRD Detection in Acute Myeloid Leukemia Patients After Allo-HSCT
Risk Stratification Value of Deep NGS-MRD Detection in Acute Myeloid Leukemia Patients After Hematopoietic Stem Cell Transplantation
To assess the value of deep NGS-MRD detection for risk stratification in adult high-risk acute myeloid leukemia (AML) patients, in this prospective, single-center, observational cohort study following allogeneic hematopoietic stem cell transplantation (allo-HSCT). A total of 169 patients will be enrolled, and deep NGS-MRD testing will be performed at approximately +3 months after transplantation. Patients will be stratified into NGS-MRD-positive and NGS-MRD-negative groups based on test results. No investigational interventions will be administered. Follow-up analyses will evaluate the associations between NGS-MRD status and post-transplant relapse and survival.

To assess the risk-stratifying value of deep NGS-MRD detection in high-risk acute myeloid leukemia (AML) patients following allogeneic hematopoietic stem cell transplantation (allo-HSCT), this prospective, single-center, observational cohort study plans to enroll 169 patients. Deep NGS-MRD testing will be performed at approximately +3 months after transplantation.
