Young smokers' interpretations of the estimated lung cancer risk associated with a common genetic variant of low penetrance

Lung cancer and family-centered patient concerns

BACKGROUND

The risk factors, diagnosis, management, and outcomes for lung cancer (LC) are a family experience. Genetic and environmental factors interact to predispose certain groups to LC, including family member, and the family or caregiving unit experiences the disease course as an interdependent group. This qualitative study examined the concerns and preferences of LC patients about incorporating family in addressing their lung cancer experiences and cancer risks.

METHODS

This project aims to identify concerns and preferences for addressing family history documentation, risk assessment, prevention, and follow-up issues for LC patients and their family. We held focus groups (FG) to discuss the format and timing of addressing these preferences and concerns. The qualitative data was analyzed using a grounded theory approach.

RESULTS

7 FG totaling 17 participants were conducted. The mean age was 64. All patients had advanced lung cancer. Participants included five males; nine African-Americans; three current, 11 former and three never smokers. Five participants had parents or grandparents with LC. Two had siblings with LC. Six themes were identified: (1) Varied journeys to LC diagnosis. (2) Mixed patient perceptions of cancer causation. (3) Limited documentation and utilization of family history. (4) Diverse attitudes toward smoking cessation. (5) A range of discussions about cancer risk, prevention, and screening. (6) Implications for implementation of family-centered cancer care and health promotion.

CONCLUSIONS

The diagnosis of LC, its management, and outcomes occur in the family context. The diagnosis represents a potential teachable moment with opportunity to reduce the risk of LC development or improve early detection in a population at higher risk of developing lung cancer. Lung cancer patients are interested in discussing risk factors, prevention, and diagnosis of lung cancer for their relatives.

"I don't believe it." Acceptance and skepticism of genetic health information among African-American and White smokers

RATIONALE

Effective translation of genomics research into practice depends on public acceptance of genomics-related health information.

OBJECTIVE

To explore how smokers come to accept or reject information about the relationship between genetics and nicotine addiction.

METHODS

Thirteen focus groups (N = 84) were stratified by education (seven < Bachelor's degree, six ≥ Bachelor's degree) and race (eight black, five white). Participants viewed a 1-min video describing the discovery of a genetic variant associated with increased risk of nicotine addiction and lung cancer. Next, they provided their opinions about the information. Two coders analyzed the data using grounded theory.

RESULTS

Pre-video knowledge about why people smoke cigarettes and what genetic risk means informed beliefs about the relationship between genes and addiction. These beliefs were not always consistent with biomedical explanations, but formed the context through which participants processed the video's information. This, in turn, led to information acceptance or skepticism. Participants explained their reactions in terms of the scientific merits of the research and used their existing knowledge and beliefs to explain their acceptance of or skepticism about the information.

CONCLUSION

Laypeople hold complex understandings of genetics and addiction. However, when lay and biomedical explanations diverge, genetics-related health information may be rejected.
