description Evidence-based guidelines recommend cascade genetic testing of blood relatives of known Hereditary Breast and Ovarian Cancer (HBOC) or Lynch Syndrome (LS) cases, to inform individualized cancer screening and prevention plans. The study identified interventions designed to facilitate family communication of genetic testing results and/or cancer predisposition cascade genetic testing for HBOC and LS. We conducted a systematic review and meta-analysis of randomized trials that assessed intervention efficacy for these two outcomes. Additional outcomes were also recorded and synthesized when possible. Fourteen articles met the inclusion criteria and were included in the narrative synthesis and 13 in the meta-analysis. Lack of participant blinding was the most common risk of bias. Interventions targeted HBOC (<i>n =</i> 5); both HBOC and LS (<i>n =</i> 4); LS (<i>n =</i> 3); or ovarian cancer (<i>n =</i> 2). All protocols (<i>n =</i> 14) included a psychoeducational and/or counseling component. Additional components were decision aids (<i>n =</i> 4), building communication skills (<i>n =</i> 4), or motivational interviewing (<i>n =</i> 1). The overall effect size for family communication was small (<i>g =</i> 0.085) and not significant (<i>p =</i> 0.344), while for cascade testing, it was small (<i>g =</i> 0.169) but significant (<i>p =</i> 0.014). Interventions show promise for improving cancer predisposition cascade genetic testing for HBOC and LS. Future studies should employ family-based approaches and include racially diverse samples.
