Ethical, legal, and social issues related to genetics and genomics in cancer: A scoping review and narrative synthesis

Genomics is increasingly being incorporated into models of care for cancer. Understanding the ethical, legal, and social issues (ELSI) in this domain is important for successful and equitable implementation. We aimed to identify ELSI scholarship specific to cancer control and genomics. To do this, we undertook a scoping literature review and narrative synthesis, identifying 46 articles that met inclusion criteria. Eighteen ELSI themes were developed, including (1) equity of access, which included structural barriers to testing and research, access to preventive and follow-up care, and engagement with health systems; (2) family considerations, such as an ethical obligation to disseminate relevant genomic information to at-risk family members; (3) legal considerations, including privacy and confidentiality, genetic discrimination, and the prospective duty to reclassify variants; and (4) optimizing consent processes in clinical care and research. Gaps in the literature were identified with respect to equity for people living in rural or remote areas, and how to provide ethical care within culturally, linguistically, and ethnically diverse communities, including First Nations peoples. Our findings suggest a need for a multidisciplinary approach to examining ELSI in cancer genomics beyond initial test indication and within the broader context of the mainstreaming of genomics in health care.
