OA07.06 - Patient Knowledge and Expectations Related to Return of Genomic Results in the Lung-MAP (SWOG 1400) Biomarker-Driven Clinical Trial (Now Available) (ID 730)
11:00 - 12:30 | Author(s): Katherine D. Crew
Biomarker-driven clinical trials (BDCTs)--where participants qualify for targeted therapy sub-studies based on tumor genomic testing results--represent a new paradigm in oncology clinical trials. However, BDCTs’ complex designs are difficult to communicate to patients considering participation, and deficits in knowledge and expectations have implications for shared decision-making and informed consent. The objective of this pilot study was to evaluate patient knowledge and expectations related to return of genomic results in the Lung-MAP (SWOG 1400) BDCT.Method
From 8/2017 to 4/2019, we recruited a subset of participants with advanced non-small cell lung cancer (NSCLC) from among patients enrolled in the Lung-MAP genomic screening study (SWOG 1400). Participants completed a 38-item telephone survey conducted by trained staff within 30 days of consent. Survey questions assessed patient knowledge about the benefits and risks of study participation and expectations about return of genomic results in the study. The survey was structured as 5-level scale responses (‘strongly disagree’  to ‘strongly agree’ ) and true/false/don’t know. Survey questions were adapted from prior studies that evaluated knowledge and expectations about return of genomic results. Descriptive statistics (means, medians, proportions) were assessed in this preliminary analysis.Result
Among 123 participants, median age was 67, 61.0% were male, 95.1% were white, 22.0% had a 4-year college education or more, and 28.5% had a household income of <$25,000/year. In the overall sample, 82.9% ‘strongly/somewhat agreed’ with the statement ‘I received enough information about the testing in Lung-MAP to understand the benefits of enrolling’ and 73.2% ‘strongly/somewhat agreed’ with the statement ‘I received enough information…to understand the risks of enrolling’. Among the sub-group that ‘strongly/somewhat agreed’ with understanding trial benefits: 89.2% correctly believed that it was ‘true’ that test results would help to select their cancer treatment (8.8% responded ‘don’t know’), 8.8% correctly believed it was ‘false’ that the somatic testing in the study would provide information to find out if family members had increased risk of cancer (40.2% responded ‘don’t know’), and 11.8% correctly believed it was ‘false’ that results would tell them about their risk of developing diseases besides cancer (38.2% responded ‘don’t know’).Conclusion
Among participants in a large BDCT, a majority of participants had serious deficits about the reporting of genomic results despite reporting to have enough information to understand benefits and risks. Our findings suggest that further research is needed to identify effective approaches to communicating information about BDCTs to improve patient knowledge about return of genomic results.
