Abstract:

Many cancers are characterized by tremendous heterogeneity in clinical outcome following standard therapies such as in multiple myeloma (MM). Accurately characterizing such heterogeneity and identifying patients at different risk groups can help uncover disease subtypes and help physicians develop targeted therapies. In recent years, many risk stratification models have been developed using genomic data. At UAMS (the University of Arkansas for Medical Sciences), a genomic 70-gene risk model has successfully identified high risk groups of MM patients for relapse. Here we present a finite mixture survival model to refine the risk assignment of this 70-gene model in the hope of better classifying patients with risk scores near the boundary of high and low risk. We discuss results from applying the mixture model to a large, UAMS myeloma clinical trial data set.
