Summary Background Current guidelines recommend different screening approaches for individuals with a family history of Barrett's oesophagus (BO) or oesophageal adenocarcinoma (OAC), varying from no screening to screening all individuals with a positive family history. Aims To determine evidence‐based risk estimates for individuals with a family history of BO or OAC Methods We systematically searched Pubmed, Embase and Cochrane Library until October 2020 to identify all studies that reported on the association between family history and the risk of BO and OAC. Pooled summary estimates of adjusted relative risks and prevalence of familial BO/OAC with 95% confidence intervals (CIs) were calculated using a random effects model. Results Fourteen studies comprising 16 189 BO/OAC patients were analysed. Familial clustering was seen in 8.84% (95% CI: 5.54‐13.82) and 4.37% (95% CI: 2.15‐8.69) of patients with BO and OAC, respectively (nine studies). Screening first‐degree relatives of BO patients had a diagnostic yield between 12% and 44% for BO (four studies). However, the yield for high‐grade dysplasia and OAC was low (<2%). Individuals with a positive family history had a higher risk of having BO (aRR 3.26; 95% CI 1.43‐7.40; I 2 = 46%; three studies) and OAC (aRR 2.19; 95% CI 1.14‐4.21; I 2 = 48%; five studies) compared to individuals without a family history. Conclusions A verified family history of BO or OAC is a strong risk factor for both BO and OAC. A positive family history could be a clinically meaningful way to identify high‐risk individuals who may benefit from early detection strategies.
