Roadmap to cure multiple myeloma

Abstract

Despite significant advances in the treatment of multiple myeloma which had led to unprecedented rates of response and survival, patients still relapse, and cure remains elusive. We propose in this review a roadmap to achieve the dream of cure for multiple myeloma based on five complementary strategies. First, to increase knowledge about disease pathogenesis with a focus on the biology of circulating tumor cells, responsible for dissemination and extramedullary disease, and minimal residual disease clones who represent the reservoir of clonal evolution and disease recurrence. Second, to consider undetectable measurable residual disease (MRD), defined by high-sensitive techniques, as the new endpoint of therapy. Third, to treat disease causation instead of symptomatology through early detection and intervention. Thereby, by treating high-risk smoldering myeloma patients early, we may not only contribute to delay disease progression into active disease but also to increase the cure rates. Fourth, to use the most active scheme in standard-risk patients if the cure is in the horizon. Fifth, to investigate experimental therapies in newly diagnosed patients with high-risk MM, implementing early rescue intervention strategies with the goal of eradicating all tumor clones, and achieving minimal residual disease negativity.
