Replacing Bone Marrow Diagnostics With Peripheral Blood Analysis in Cytopenia Patients

Summary

This observational, multi-center study aims to collect data in order to develop a novel, minimally invasive diagnostic tool for MDS based on peripheral blood profiling of circulating hematopoietic stem and progenitor cells (cHSPCs) using single-cell RNA sequencing and DNA sequencing.

Detailed Description

This observational, multi-center study aims to collect data in order to develop a novel, minimally invasive diagnostic tool for MDS based on peripheral blood profiling of circulating hematopoietic stem and progenitor cells (cHSPCs) using single-cell RNA sequencing and DNA sequencing. Current MDS diagnosis relies on bone marrow (BM) aspiration and biopsy, which is invasive, technically challenging, and sometimes inconclusive, particularly in early or low-risk disease. Our prior research established a healthy reference map of cHSPC subtypes and developed a computational pipeline that distinguishes MDS from non-clonal cytopenias based on deviations from this reference. In this study, patients referred, as part of standard care, for BM evaluation due to unexplained cytopenias or abnormal blood counts and undergo PB collection for genomic profiling. The study's primary objective is to develop a PB-based test by comparing the developed test diagnoses to the conventional BM-based one. Secondary objectives include evaluating its potential for MDS risk stratification and assessing its ability to reduce the need for BM evaluations.
