Cancer clinical trials provide the best evidence for showing the efficacy of new treatments. However, only a small percentage of adult patients with cancer participate in clinical trials.1 The issue of income disparities in clinical trial participation has been poorly addressed; limiting income disparities is important for ensuring rapid enrollment and fair access to trials. Our research group previously found that patients with annual household incomes below $50 000 were 27% less likely to participate in clinical trials.2 This provocative result was derived from one of many analyses of demographic and socioeconomic factors within a single, cross-sectional data set and so was considered hypothesis generating. The confirmation of this finding with prospectively collected data is critical for affirming its validity.
