Strategies for risk-adapted therapy in myeloma.
It is clear that the clinical heterogeneity of multiple myeloma (MM) is dictated, in large part, by disease biology, predominantly genetics.(1) As novel therapeutics have emerged, and augmented our treatment armamentarium against the disease, it is increasingly important to introduce a risk-adapted approach for the optimal management of patients.(2) The selection of ideal candidates for high-dose chemotherapy with stem cell support (HDT) and maintenance will undoubtedly have to include baseline knowledge of the genetic nature of the individual. The limited duration of responses after HDT for patients with t(4;14)(p16;q32), t(14;16)(q32;q23) and 17p13 deletions highlight the need to develop a risk-adapted treatment strategy.(3)(-)(5) Novel ways of determining outcome such as the use of gene expression profiling have demonstrated differentiating capabilities not previously observed.(6) Likewise, the order of introduction of novel therapeutic agents (during induction and in the relapsing patient) will be potentially directed by similar information. As we have previously stated, MM is not only multiple but also "many."(7) Accordingly, treatment strategies will be tailored based on risk determination, genetic composition and host features.
