Treatment of older adult or frail patients with multiple myeloma.

Older adults with multiple myeloma (MM) are a growing population, and personalizing treatment based on disease and health status is imperative. Similar to MM staging systems that provide disease-related prognostic information, myeloma-specific frailty tools can better identify subgroups at greatest risk for treatment-related toxicity and early treatment discontinuation, as well as predict overall survival. Several myeloma-specific validated tools are well studied. Although these fitness/frailty scores have shaped our understanding of the heterogeneity among older adults with myeloma, the application of such scores in treatment decision making (ie, transplant considerations, relapse) is an unmet need. Here we outline how to incorporate frailty assessments in the evaluation of older adults with MM in the clinical setting with consideration of other factors such as patient preferences, treatment risks/benefits, life expectancy, and disease biology.
