Awareness, knowledge, perceived benefits, and barriers regarding precision medicine and willingness to participate in a national registry: Comparison of cancer patients and the general population (Preprint)
BACKGROUND Precision medicine (PM) is a growing area of interest in cancer care. Although the terms ‘precision medicine’ and ‘personalized medicine’ are used interchangeably, the former may be new both to cancer patients and the general population. Most previous studies evaluated peoples’ attitudes towards genetic testing as a part of personalized medicine and included a single stakeholder, either patients or the general population. Few studies have evaluated cancer patients’ knowledge and perception regarding PM. OBJECTIVE To evaluate cancer patients’ awareness, knowledge, as well as perceived benefits and barriers regarding PM, and their willingness to participate in a national registry for PM, in comparison to those of the general population. METHODS We conducted a cross-sectional survey on 1,500 consecutive cancer patients enrolled at two university-based cancer hospitals in Seoul, Korea; 1,500 people who were representative of the Korean population were enrolled as controls. Multivariable logistic regression was conducted to identify the factors associated with a willingness to participate in a national registry for PM. RESULTS : In the total population, 20.0% of the cancer patients had heard of PM and 35.1% were able to accurately define it. Cancer patients were three times likelier to express a willingness to participate in a national registry for PM than the general population (95% confidence interval [CI], 2.47-3.61). Participants who had heard of PM (cancer patients: adjusted odds ratio (aOR) = 1.40, 95% CI, 1.00-1.95; general population: aOR = 2.04, 95% CI, 1.62-2.56) and who had a more positive perception of the PM-related benefits (cancer patients: aOR = 2.48, 95% CI, 1.88-3.27; general population: aOR = 1.34, 95% CI, 1.05-1.71) were likelier to be willing to participate in a national registry for PM. CONCLUSIONS While PM is gaining importance in clinical settings, a majority of cancer patients are not well-informed about it. Nevertheless, the patients in our study perceived PM as being associated with various benefits and showed a willingness to participate in a national registry for PM. Considerable efforts need to be taken to educate the public and advocate participation in studies on PM
