Evaluation of Adolescents' and Young Adults' Attitudes Toward Participation in Cancer Clinical Trials.

PURPOSE

Participation in cancer clinical trials (CCTs) for adolescents and young adults (AYAs) remains the lowest of any patient group with cancer. Little is known about the personal barriers to AYA accrual. The aim of this study was to explore AYA attitudes that influence CCT participation.

METHODS

A mixed-methods approach was used. AYAs and non-AYAs (≥ 40 years) completed the Cancer Treatment subscale of the Attitudes Toward Cancer Trials Scales and 9 supplementary questions formed from interview analysis. Differences between AYA and non-AYA cohorts were analyzed using the Mann-Whitney test, and logistic regression models were constructed to evaluate the effect of demographics on perceptions of CCTs.

RESULTS

Surveys were distributed to 61 AYAs (median age, 29 years; range, 17-39 years) and 74 non-AYAs (median age, 55 years; range, 40-88 years). Compared with non-AYAs, AYAs perceived CCTs to be unsafe/more difficult (Personal Barrier/Safety domain; = .01). There were no differences based on age in other domains. AYAs were also more concerned with CCT interference in their long-term goals ( = .04). Multivariable ordered logistic regression identified increased personal barriers in the Personal Barrier/Safety domain for AYAs ( = .01), in patients with English as a second language (ESL; < .01), and in patients previously not offered a clinical trial ( = .03). Long-term goals were identified as a barrier in particular tumor types ( = .01) and in patients with ESL ( < .01), with a trend identified in AYAs ( = .12).

CONCLUSION

Age-related differences in attitudes toward CCTs suggest that tailored approaches to CCT accrual are warranted. Patient-centered delivery of information regarding CCTs, particularly in patients with ESL and who are trial naïve, may improve accrual.
