dc.description.abstractMyeloma is an incurable malignancy of plasma cells in the bone marrow. Improvements in myeloma treatment have highlighted the need for more sensitive non-invasive measures of residual disease. Circulating tumour DNA in the plasma fulfils this need, but the use of mutation-based monitoring is limited by the vast genetic heterogeneity of myeloma, by the known clonal evolution of myeloma and the cost. To avoid these limitations, a novel approach using methylation differences to distinguish circulating myeloma DNA from healthy cell-free DNA was designed. A final biomarker panel consisting of two differentially methylated genes (PPFIA1 and SLC9A3) was identified. This panel was measurable in more patients (84.4%) compared to conventional protein biomarkers (55%) or a targeted sequencing panel of the commonest genetic mutations (63-68%). Additional advantages of this novel circulating tumour DNA biomarker panel include a “real-time” representation of disease burden and being able to track clonal evolution. Based on a small number of cases, these methylation biomarkers reflect response to treatment, predict relapse earlier and potentially guide therapeutic choices. Follow up studies to validate these results are required.
