Mass Spectrometry Quantification of Personalized Biomarkers for Multiple Myeloma

Multiple Myeloma, an incurable disease with poor patient outcomes, is characterized by clonal expansion of the plasma cells in the bone marrow, which secrete a monoclonal immunoglobulin. This study utilizes a proteogenomics approach to develop individualized, peptide-based mass spectrometry assays to quantify each patient’s disease-specific biomarker. Personalized LC-MRM assays developed for variable region peptides using de novo RNA sequencing have shown a substantial increase in sensitivity compared to clinical methods. The increase in sensitivity improves minimal residual disease detection, which could improve patient outcomes.
