Quality matters
At diagnosis Partial response (50% reduction in M protein) Near complete remission (immunofixation pos only) Complete remission (immunofixation neg) 1 × Number of myeloma cells 1 × 10 8 Why stop at CR, when we are not yet done? Cure MRD- Non-quantitative ASO-PCR of bone marrow Quantitative ASO-PCR of bone marrow High quality flow cytometry of bone marrow Deep sequencing of bone marrow 1 × × 10 6 MRD+ 0

There is already a literature: we are already doing it! Number of published myeloma MRD studies associated with clinical outcomes Landgren et al. unpublished data
Summary and Conclusions Deeper responses in more patients Deeper responses = better survival Deeper is better, MRD next step forward
