Utilization of tumor genomics in clinical practice: an international survey among ASCO members.

Abstract

Aim: To identify patterns of use and barriers to tumor genomic testing among oncologists. Methods: We surveyed American Society of Clinical Oncology physician members about their use of genomic testing. Results: Among 11,900 members surveyed, a total of 1000 responded to the survey (participation rate, 8.4%). A total of 75% of the respondents included in the analysis reported ordering tests for at least 1-10% of their patients. Practice setting (academic vs community) was only a determinant in the ordering frequency in North America. Regardless of location, academic oncologists were more likely to prescribe medicine in the context of a clinical trial. Access to clinical trials and costs associated with testing were the barriers identified worldwide. Conclusion: There is substantial variation in the use of genomic tools according to region and practice setting; yet, the barriers are similar worldwide.
