Researchers from four Dartmouth departments—the Department of Epidemiology, Dartmouth Cancer Center, the Department of Pathology and Laboratory Medicine, and the Department of Molecular and Systems Biology—have published a new study titled, "Continuous DNA methylation deconvolution-based surrogate for B-cell differentiation state in chronic lymphocytic leukemia."
The research team developed a novel metric, the B-Index, to capture chronic lymphocytic leukemia (CLL) along a continuous spectrum of B-cell differentiation, reflecting the many developmental stages from which CLL may arise. The study found that the B-Index accurately classifies CLL clinical subtypes with 98.8% accuracy, exhibits a stronger epigenetic signal than IGHV gene percent identity, and reveals additional biological variation within established clinical subgroups.
These findings provide a more nuanced understanding of CLL biology and may help advance future research into disease classification and progression.
