Andrew Staron, MD, Boston Medical Centre, Boston, MA, discusses the assessment of minimal residual disease (MRD) using multiparametric flow cytometry in treated patients with AL amyloidosis. This is a powerful analytical and preparative tool that enables the rapid measurement of multiple physical and chemical characteristics of individual cells and may allow for increased accuracy in patient stratification. This interview was recorded via an online conference call with The Video Journal of Hematological Oncology (VJHemOnc).
