PURPOSE:Identify key barriers that keep Latinos from participating in clinical trials (CTs) and interventions proven effective in increasing their representation in clinical research.METHODS:Utilize our own extensive research experience and review the literature to: Identify key barriers, summarize strategies that have been proven effective in increasing Latino representation in CTs, issue a call to action for programs/practices and practitioners to implement what is proven effective, and make recommendations for further research to address current gaps.RESULTS:Participation barriers are complex, multifactorial, and exist at different levels, including study design (eg, protocol complexity, patient exclusion criteria, trial duration and frequency), healthcare system barriers (eg, lack of minority staff), patient-related factors (eg, lack of awareness, low health literacy, language, social determinants of health [SDoH]), and medical team issues (eg, lack of cultural competence, lack of referrals, implicit bias, provider/patient communication). Research has shown that the most effective strategies to increase participation of underrepresented minorities in CTs include culturally sensitive educational tools aimed at community members, patients, and physicians, and strategies to address the multiple SDoH and other barriers to participation facing cancer patients and the factors that influence patient decision-making.CONCLUSION:Raising awareness or offering clinical trials to everyone will not alone increase Latino participation. Other key barriers at different levels must also be addressed, especially SDoH and patients' contextual factors. To achieve equitable participation of Latinos and other underrepresented groups in clinical research, comprehensive approaches that address interrelated multilevel and multifactorial barriers to participation can produce a substantial, sustained impact-ensuring everyone equitably benefits from scientific advances in cancer treatment, improved cancer outcomes and quality of life, and reduced health care costs.
