Historically defined as cancer cells undetectable by conventional morphology, MRD is now more appropriately termed measurable residual disease, reflecting its quantitative and clinically actionable nature. Advances in next-generation flow cytometry and next-generation sequencing have enabled detection of disease at sensitivities as low as 10<sup>−6</sup> and even 10<sup>−7</sup>, redefining the concept of complete response. Nonetheless, challenges remain regarding assay sensitivity, standardization, and interpretation of results. Achieving MRD-negativity is a strong and independent predictor of improved survival outcomes in both newly diagnosed and relapsed/refractory MM. Consequently, MRD negativity has increasingly been accepted by regulatory agencies as an intermediate endpoint supporting accelerated drug approval.

The results are organized using the socio-ecological model across patient, provider, institutional, and policy levels, and highlight how these barriers and facilitators can disproportionately affect racial and ethnic minority populations. Barriers are complex and present at all socio-ecological levels, and only two published interventions that target minority access disparities to CAR-T therapy were identified.
