Peters Y, van Grinsven E, Siersema PD. Systematic review with meta-analysis: the effects of family history on the risk of Barrett's oesophagus and oesophageal adenocarcinoma. Aliment Pharmacol Ther 2021; 54:868-879. [PMID: 34383966 PMCID: PMC9292032 DOI: 10.1111/apt.16558] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/12/2021] [Revised: 05/03/2021] [Accepted: 07/19/2021] [Indexed: 12/09/2022]
Abstract
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; I2 = 46%; three studies) and OAC (aRR 2.19; 95% CI 1.14-4.21; I2 = 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.

Abstract
BACKGROUND Considering the poor prognosis of oesophageal adenocarcinoma (EAC), it is important to identify individuals at increased risk of developing EAC who may benefit from early detection and prevention strategies. We aimed to determine whether individuals with a positive family history of Barrett's oesophagus (BE) and EAC are at an increased risk of oesophageal neoplasia. METHODS In a multi-centre case-control study, BE patients with or without related oesophageal neoplasia and randomly selected population controls filled out a questionnaire to collect information on family history and other risk factors for BE and EAC. Positive family history was defined as having ≥1 first-degree relative with BE or EAC whose diagnosis was histologically confirmed in the Dutch nationwide histopathology database. FINDINGS We included 480 BE patients and 420 controls without BE who had a total of 6393 first-degree relatives. A pathologically confirmed positive family history was significantly higher in BE patients compared with controls (6.5% versus 0.9; p < 0.001). Positive family history was independently associated with an increased risk of BE (OR 5.04; 95% CI 1.45-17.58; p = 0.01) after adjusting for known risk factors, such as gastroesophageal reflux disease and body mass index, and family size. INTERPRETATION We found that familial clustering of BE and EAC is present in 6.5% of Dutch BE patients. Subjects with ≥1 first-degree relative with BE or EAC have a 5-fold increased risk of BE and EAC. These findings emphasize the importance of a detailed family history in patients with BE or EAC to identify individuals at increased risk who may benefit from early detection strategies to prevent EAC-related mortality.

Abstract
The vast majority of esophageal adenocarcinoma cases are sporadic and caused by somatic mutations. However, over the last decades several families have been identified with clustering of Barrett’s esophagus and esophageal adenocarcinoma. This observation suggests that one or more hereditary factors may play a role in the initiation of Barrett’s esophagus and esophageal adenocarcinoma in these families. A Dutch family with clustering of Barrett’s esophagus and esophageal adenocarcinoma was identified. Normal DNA obtained from the proband diagnosed with Barrett’s esophagus was analyzed with SNP array and exome sequencing. A custom-made panel consisting of potential germline variants was verified in the normal DNA of the affected family members. In addition, the respective tumors were analyzed for somatic loss of the wild type allele or the presence of an inactivating somatic mutation in the wild type allele. Exome sequencing revealed 244 candidate variants in the normal DNA of the proband, of which 212 variants were verified successfully. After the normal DNA of the affected family members was analyzed for the presence of the 212 potential germline variants and subsequently the respective tumors, only one potential germline variant in MSX1 (chr4: 4861985 T > G, c.359T > G, p.V120G, NM_002448) showed loss of the wild type allele in the tumor DNAs of the affected family members. A germline variant in MSX1 was identified in a Dutch family with clustering of Barrett’s esophagus and esophageal adenocarcinoma. This finding indicates that the germline defect in MSX1 may be associated with Barrett’s esophagus and cancer in this particular family.

Abstract
Background The significance of a family history of esophageal adenocarcinoma in the progression to esophageal adenocarcinoma in patients with Barrett's esophagus has not been thoroughly evaluated. The purpose of this study is to evaluate the presence of esophageal adenocarcinoma in a first-degree relative in patients with Barrett's esophagus. Methods A retrospective cohort study was conducted of patients with Barrett's esophagus at a tertiary care center undergoing radiofrequency ablation. Family history, demographics, and pathology and endoscopy reports were assessed in all patients. Findings Three hundred and one patients with Barrett's esophagus were assessed. Nineteen patients who had a diagnosis of esophageal adenocarcinoma on index endoscopy were excluded. Nineteen (6.7%) patients had a first-degree relative with esophageal adenocarcinoma. Four (21.1%) of these patients progressed to esophageal adenocarcinoma. Of patients without first-degree relative with esophageal adenocarcinoma 22/263 (8.7%) progressed to esophageal adenocarcinoma. In a logistic regression model adjusted for sex and the number of radiofrequency ablation treatments, we found that family history of esophageal adenocarcinoma was a significant independent predictor of progression to esophageal adenocarcinoma (odds ratio = 5.55, 95% confidence interval: 1.47-20.0). Conclusion Our study indicates that Barrett's esophagus patients with a first-degree family member with esophageal adenocarcinoma are at 5.5-fold higher risk for disease progression to esophageal adenocarcinoma. Family history of esophageal adenocarcinoma in Barrett's esophagus patients should be considered in patient surveillance and radiofrequency ablation treatment, beyond recommended guidelines.

Abstract
Barrett's esophagus (BE) is intestinal metaplasia of the lower esophagus and a precursor lesion for esophageal adenocarcinoma (EAC). Both are important health issues as they have rising incidences in the Western world. Improving the management of BE relies on understanding the underlying biology of this disease, but the exact biological mechanisms have been difficult to determine. BE is generally thought to be an acquired condition that develops secondarily to chronic gastroesophageal reflux. However, multiple reports of familial clustering of patients with BE and/or EAC suggest a possible inherited predisposition to BE may be driving this condition, at least in a subset of patients. Identifying the genetic variants that predispose to BE in these families would open up the possibility for blood-based screening tests that could inform decision-making in regard to surveillance strategies, particularly for relatives of patients with BE and/or EAC. Perhaps more importantly, understanding the genetic mechanisms that predispose to BE may provide valuable insights into the biology of this condition and potentially identify novel targets for therapeutic intervention. Here we review the current evidence for a genetic predisposition to BE and discuss the potential implications of these findings.

Abstract
Esophageal adenocarcinoma (EAC) is typically diagnosed in elderly with a median age of 68 years. The incidence of EAC has been rising over the last decades, also among young adults. The aim of the study was to investigate whether early onset EAC is a distinct molecular entity. To identify early onset EACs, the nationwide network and registry of histo- and cytopathology in the Netherlands (PALGA) was searched. Twenty-eight tumors of patients aged ≤40 years were selected and matched with 27 tumors of patients aged ≥68 years. DNA was isolated from surgically resected specimen and sequenced on the Ion Torrent Personal Genome Machine with the Ion AmpliSeq Cancer Panel. No differences in mutational load between early onset and conventional EACs were observed (P=0.196). The most frequently mutated genes were TP53 (73%) and P16 (16%). Additional mutations in early onset EACs occurred exclusively in: APC, CDH1, CTNNB1, FGFR2, and STK11. In the conventional EACs additional mutations were exclusively identified in: ABL1, FBXW7, GNA11, GNAS, KRAS, MET, SMAD4, and VHL. Additional mutations besides TP53 and P16 seem to occur in different genes related to cell fate pathways for early onset EACs, while the additional mutations in conventional EACs are related to survival pathways.

Abstract
BACKGROUND & AIMS Up to 7% of cases of Barrett's esophagus (BE) or esophageal adenocarcinoma (EAC) in the United States occur in family clusters. We identified first-degree and second-degree relatives of patients with BE and EAC to determine the extent of familial clustering in a European cohort and studied differences between familial and nonfamilial cases. METHODS A questionnaire was sent to all patients diagnosed with BE or EAC from 2000-2011 at 3 hospitals in the Netherlands (n = 838). Diagnoses of affected relatives were confirmed by using the Dutch Pathology Registry. Familial statuses of BE were defined as definitive (≥1 first-degree or second-degree relative with BE or EAC), possible (≥1 reported relative with BE or esophageal cancer without histologic confirmation), unlikely (no family history), or unknown. RESULTS A total of 603 patients with BE or EAC (71%) responded and were included in the analysis. Familial BE was definitive for 7% of cases (n = 39, 10% of first-degree relatives affected), possible for 6% (n = 36), unlikely for 49% (n = 297), and unknown for 38% (n = 231). Definitive cases of familial BE were younger at onset of heartburn and EAC diagnosis; their first-degree relatives more frequently had reflux symptoms and a prior upper endoscopy, compared with unlikely cases of familial BE. CONCLUSIONS In a database analysis of patients diagnosed with BE or EAC in the Netherlands, 7% of cases of BE and EAC were familial. These cases have a younger average age of onset of reflux symptoms and diagnosis of EAC than unlikely familial cases. These findings may indicate that genetic factors contribute to BE susceptibility, with a possible central role of gastroesophageal reflux.

Abstract
BACKGROUND The vast majority of Barrett's esophagus (BE) and esophageal adenocarcinoma (EAC) cases are sporadic and caused by somatic mutations. However, over the last decades several families have been identified with clustering of EAC. Here, we review data from the published literature in order to address the current knowledge on familial EAC. SUMMARY Although familial EAC comprises a relatively small group of patients, it is a clinically relevant category due to the poor prognosis of this type of cancer. Efforts should be made to identify specific genetic risk factors for familial EAC to enable identification of relatives at risk, since endoscopic surveillance can diagnose preneoplastic or early neoplastic lesions leading to early treatment, with improved outcome. KEY MESSAGE Although familial EAC comprises a relatively small group of patients, this is a clinically relevant category due to the poor prognosis. Efforts should be made to identify specific genetic risk factors for familial EAC in order to facilitate the identification of other family members with a predisposition for this type of cancer. PRACTICAL IMPLICATIONS Approximately 7% of BE and EAC cases are considered familial. Age at diagnosis is generally lower for patients with familial EAC as compared to sporadic cases, while other known risk factors for EAC, such as male gender and Caucasian ethnicity, do not differ between the two groups. In several described families with clustering of EAC the pattern of inheritance seems to be consistent with a rare autosomal dominant genetic trait. However, some association has been found with (attenuated) familial adenomatous polyposis, mismatch repair deficiency and recently with the genes MSR1, ASCC1 and CTHRC1. Nevertheless, no specific genetic predisposition has yet been identified.

Abstract
Barrett's esophagus (BE) is a well-established pre-malignant lesion for esophageal adenocarcinoma, a condition that carries a dismal five-year overall survival rate of less than 15%. Among several available methods to eliminate BE, radiofrequency ablation (RFA) provides the most efficient modality, since it has been demonstrated to successfully eradicate BE with or without dysplasia with acceptable safety, efficacy and durability profiles. In conjunction with proton pump therapy, this new technology has quickly become the standard care for patients with dysplastic BE. However, several technical questions remain about how to deploy RFA therapy for maximum effectiveness and long-term favorable outcomes for all stages of the disease. These include how to select patient for therapy, what the best protocol for RFA is, when to use other modalities, such as endoscopic mucosal resection, and what should be considered for refractory BE. This review addresses these questions with the perspective of the best available evidence matched with the authors' experience with the technology.
