高危多发性骨髓瘤：诊断时和复发时如何治疗？

Patients with multiple myeloma have experienced a great improvement in survival over the past century because of the introduction of novel therapeutic strategies.

However, a subgroup of patients with poorer outcomes than expected is considered high risk and identified by the presence of patient- and disease-based factors such as frailty, extramedullary disease, cytogenetic abnormalities, or even relapses occurring earlier than expected according to the baseline factors. Although the management of patients with high-risk features is not well established because of the lack of specific trials in this subgroup of patients and because of their underrepresentation in the clinical trials, treatment should be planned on 2 pillars: (1) poor prognosis with the presence of high-risk features can be at least improved or even abrogated by achieving a deep and sustained response over time, and (2) this can most likely be obtained through using the best therapeutic options and in a response-adapted way.

Some clinical trials that have been planned or are ongoing include only patients with high-risk features, using the most effective therapies (proteasome inhibitors, immunomodulatory drugs, and anti-CD38 monoclonal antibodies) as well as chimeric antigen receptor T cells and T-cell engagers that will unravel what the best therapeutic approach will be to overcome the poor prognosis of the presence of high-risk features.
