An Examination of the Influence of Patient Race and Ethnicity on Expressed Interest in Learning About Cancer Clinical Trials

Purpose: A number of factors have been identified as being associated with the documented low accrual rate of minorities into cancer-related clinical trials in the USA. An important issue is the fundamental interest, or lack thereof, of these specific patient populations in actually considering study participation.

Methods: To examine this issue, aggregate data were analyzed from a proprietary Internet-based decision support program (NexProfiler Treatment Option Tools for Cancer, NexCura, Seattle, WA, USA) embedded into approximately 100 cancer-associated Web sites where responding patients (or their families) were asked, but not required, to identify their race/ethnicity (African-American, Asian-American, Caucasian and Hispanic) and to also respond to the question, "Are you interested in learning about clinical trials?".

Results: Of the > 60,000 patients who both self-identified their race/ethnicity and responded to the question regarding their desire to learn about clinical trials, approximately 10% were from the minority (non-Caucasian) groups. Of note, in all four malignancies analyzed (breast, colorectal, lung, and prostate) and in both patients < or = 60 and > 60 years of age, each of the three non-Caucasian populations expressed an interest in learning about such studies that was equal to, if not greater than, that observed in the Caucasian respondents.

Conclusion: Assuming these provocative results regarding self-declared desire to learn about clinical trials can be confirmed by others with similar Internet-associated databases, this analysis suggests Web-based recruitment strategies may be an effective method to communicate with minority populations in the US (and, perhaps, elsewhere) with a specific interest in considering participation in cancer clinical trials.
