Cancer-related genetic and genomic testing (CGT) is changing cancer care by personalizing care options, leading to an era of precision medicine. Advances in and increased use of CGT add complexity to clinical communication. This landscape analysis assessed published reviews of communication issues related to CGT and discusses implications for practice and behavioral research. A comprehensive electronic literature search was conducted of peer-reviewed literature reviews on studies related to CGT communication published between January 2010 and January 2017, resulting in a final sample of 24 reviews. Reviews were categorized, with overlaps, into four domains across the genetic testing communication continuum. Reviews on CGT-related knowledge, attitudes, and perceptions (n = 8) found that despite substantial public interest, their knowledge and awareness remains low. Providers also reported insufficient knowledge and overall caution, particularly regarding direct-to-consumer (DTC) genetic testing. Reviews of decision-making about CGT and test uptake (n = 8) identified individual, interpersonal, and systems-level barriers to uptake. Reviews of patient-provider CGT communication (n = 8) revealed limited communication and little empirical research on outcomes of communication or efforts at improving clinical and family communication. There were mixed findings in reviews (n = 15) on the psychological and behavioral impact of CGT, and DTC testing particularly had little effect on behaviors. Taken together, there is very little extant research in CGT in minority and underserved communities. In order for scientific advances in CGT to translate into equitable, patient-centered care, behavioral research, including health literacy and communication, plays critical roles.
