Patient-Tailored Measurable Residual Disease Monitoring in Peripheral Blood Using Deep Sequencing and Droplet Digital PCR for Early Detection of Relapse in Childhood Acute Myeloid Leukemia: A NOPHO-DBH Collaborative Study
Blood(2021)
摘要
Close surveillance of measurable residual disease (MRD) following completion of therapy for acute myeloid leukemia (AML) enables early detection of relapse in time for pre-emptive treatment. Today this is available only for the fraction of patients with recurrent targets quantifiable with standardized RT-qPCR. Patient-tailored MRD monitoring based on leukemia-specific mutations may be an attractive option in patients lacking such aberrations. In this population-based study, we used whole exome sequencing (WES) to identify leukemia-specific mutations suitable for MRD monitoring, and targeted deep sequencing (deep seq) and droplet digital PCR (ddPCR) for quantitative monitoring in children with AML. We investigated the clinical applicability of patient-tailored deep seq and ddPCR for early detection of AML relapse in peripheral blood (PB).
