Genomic testing in cancer: Patient knowledge, attitudes, and expectations

BACKGROUND Genomic testing in cancer (GTC) characterizes genes that play an important role in the development and growth of a patient's cancer. This form of DNA testing is currently being studied for its ability to guide cancer therapy. The objective of the current study was to describe patients' knowledge, attitudes, and expectations toward GTC. METHODS A 42‐item self‐administered GTC questionnaire was developed by a multidisciplinary group and patient pretesting. The questionnaire was distributed to patients with advanced cancer who were referred to the Princess Margaret Cancer Center for a phase 1 clinical trial or GTC testing. RESULTS Results were reported from 98 patients with advanced cancer, representing 66% of the patients surveyed. Seventy‐six percent of patients were interested in learning more about GTC, and 64% reported that GTC would significantly improve their cancer care. The median score on a 12‐item questionnaire to assess knowledge of cancer genomics was 8 of 12 items correct (67%; interquartile range, 7‐9 of 12 items correct [58%‐75%]). Scores were associated significantly with patients' education level (P
