Resumen:
Multiple myeloma (MM) is the second most frequent hematological disease. Two-thirds of newly diagnosed MM patients are more than 65 years of age. Elsewhere in this issue, McCarthy et al discuss the treatment of transplantation candidates; this chapter focuses on the data available concerning therapy for non-transplantation-eligible MM patients. Treatment goals for these non-transplantation-eligible patients should be to prolong survival by achieving the best possible response while ensuring quality of life. Until recently, treatment options were limited to alkylators, but new up-front treatment combinations based on novel agents (proteasome inhibitors and immunomodulatory drugs) plus alkylating agents have significantly improved outcomes. Other nonalkylator induction regimens are also available and provide a novel backbone that may be combined with novel second- and third-generation drugs. Phase 3 data indicate that maintenance therapy or prolonged treatment in elderly patients also improves the quality and duration of clinical responses, extending time to progression and progression-free survival; however, the optimal scheme, appropriate doses, and duration of long-term therapy have not yet been fully determined. The potential for novel treatment regimens to improve the adverse prognosis associated with high-risk cytogenetic profiles also requires further research. In summary, although we have probably doubled the survival of elderly patients, this group requires close monitoring and individualized, dose-modified regimens to improve tolerability and treatment efficacy while maintaining their quality of life.
