A Randomized Trial of Precision Prevention Materials to Improve Primary and Secondary Melanoma Prevention Activities among Individuals with Limited Melanoma Risk Phenotypes.

ABSTRACT: Inherited variation at MC1R is associated with elevated melanoma risk among non-Hispanic whites (NHWs). MC1R genetic testing may unmask previously unrecognized disease risk, especially among individuals with few melanoma phenotypic risk factors. We recruited NHW individuals with limited phenotypic risk factors from two primary care clinics in west-central Florida. Participants (n = 1134) were randomized within MC1R genotype risk group (average/higher) to receive mailed precision prevention (i.e., intervention) or generic prevention materials. Participants reported hours of weekday and weekend sun exposure, frequency of intentional outdoor tanning and sun protection behaviors, number of sunburns, indoor tanning episodes, and skin examinations at baseline, and after 6 and 12 months. Among MC1R higher-risk participants, the intervention increased the likelihood of often or always wearing a shirt with sleeves (OR = 1.49, p = 0.03) and seeking shade or using an umbrella (OR = 1.42, p = 0.046), and it decreased the number of sunburns among their young children (β = -0.13, p = 0.03). Intervention effects were not noted among MC1R average-risk participants. Moderation analyses identified intervention effects within subgroups in average-risk and higher-risk participants. Precision prevention information conveying MC1R testing results can increase the practice of some sun protection behaviors among at-risk individuals with limited melanoma risk phenotypes and may provide a cross-generational tool to counteract increasing incidence of melanoma.

Project description:A randomized trial was conducted to examine whether providing precision prevention materials incorporating melanocortin-1 receptor genetic risk information would increase intention to practice melanoma preventive behaviors. Here, we determine retention/evaluation of prevention materials for adolescent and young adults (AYA) 18 to 39 years old versus adults aged 40+ at 6 and 12 months as an a priori adjunct analysis to the primary research question. Using qualitative methodology, open-ended questions probing most important information from prevention materials and additional comments were collected at 6 and 12 months after baseline. Descriptive statistics were performed on demographic/self-reported characteristics. Two independent researchers applied qualitative thematic content analysis to identify major themes in open-ended questions. Of the 1,134 participants randomized, 906 completed at least one of the follow-up surveys and contributed to analyses of intervention efficacy. Five major thematic categories emerged from the open-ended response data: (i) tips and tricks for sun protection; (ii) cancer prevention; (iii) risk factors and genetics; (iv) general information; and (v) intervention comments. Across all ages, the most important information retained were sun protection techniques in the generic prevention materials group and identifying the importance of genetic risk factors/implementing lifestyle behavior changes in the precision prevention materials group. For additional comments, AYA participants in the generic prevention materials group preferred more scientific information including statistics and citations for references while adults were more likely to state they already knew cancer prevention techniques. Results provide unique qualitative evaluation of AYA versus adult retention of prevention materials for melanoma that enhance quantitative findings.Prevention relevanceIt is important to evaluate information within groups defined by periods of the life trajectory, e.g., AYA and adults, to best inform preferences, knowledge, and motivation for behavior change. By assessing retention, evidence-based interventions can be designed to better support public health messaging and encourage positive health behaviors.
