MRDsteer: quality-aware AI-driven closed-loop optimization enhances ctDNA-based minimal residual disease detection.
Smart AI monitoring of blood cancer DNA tests catches early warning signs more reliably, helping doctors spot recurrence sooner when treatment may work best.
MRDsteer addresses a critical limitation of ctDNA-based MRD detection by implementing a closed-loop AI agent that continuously monitors multidimensional quality metrics and triggers localized re-calling only in high-risk genomic regions when reliability drops, rather than repeating the entire pipeline. Validated in simulated datasets and clinical cohorts (NSCLC + NPC in the K438 cohort), MRDsteer improved MRD stratification and PFS separation compared to representative baseline methods, suggesting practical utility for sensitive longitudinal ctDNA monitoring.
