Patient Knowledge, Risk Perception, and Barriers to Barrett's Esophagus Screening.

ABSTRACT:

Introduction

Most patients with esophageal adenocarcinoma (EAC) do not have a previous diagnosis of Barrett's esophagus (BE), demonstrating a failure of current screening practices. An understanding of patient attitudes and barriers is essential to develop and implement interventions to improve BE screening adherence.

Methods

We conducted a Web-based survey of patients aged >50 years with chronic gastroesophageal reflux disease at 3 academic medical centers and 1 affiliated safety net health systems. Survey domains included patient characteristics, endoscopy history, familiarity with screening practices, perceived BE/EAC risk, and barriers to screening.

Results

We obtained a response rate of 22.6% (472/2,084) (74% men, mean age 67.9 years). Self-identified race and ethnicity of participants was 66.5% non-Hispanic White, 20.0% non-Hispanic Black, 13.4% other race, and 7.1% Hispanic. Screening for BE was recommended in only 13.2%, and only 5.3% reported previous screening. Respondents had notable gaps in knowledge about screening indications; only two-thirds correctly identified BE risk factors and only 19.5% believed BE screening was needed for gastroesophageal reflux disease. More than 1 in 5 respondents believed they would get BE (31.9%) or EAC (20.2%) but reported barriers to screening. Compared with White respondents, more Black respondents were concerned about getting BE/EAC and interested in screening but report higher barriers to screening.

Discussion

Patients at risk for BE, particularly racial and ethnic minorities, are worried about developing EAC but rarely undergo screening and have poor understanding of screening recommendations.

Project description:Background & aimsNonsteroidal anti-inflammatory drugs (NSAIDs) have been suggested to protect against esophageal adenocarcinoma (EAC). This study examined the effect of NSAIDs on the risk of developing Barrett's esophagus (BE), the precursor lesion to EAC.MethodsWe conducted a case-control study among eligible patients scheduled for either elective esophagogastroduodenoscopy (EGD) or recruited from primary care clinics to undergo a study EGD. We compared 323 patients with BE (296 nondysplastic and 27 dysplastic) with 2 separate control groups: 1347 patients from the elective EGD group (endoscopy controls) and 502 patients from the primary care group (primary care controls) with no endoscopic or histopathologic BE. Use of aspirin products and 23 nonaspirin NSAIDs was ascertained from detailed, self-reported questionnaires. We calculated odds ratios (ORs) and 95% confidence intervals (CIs) using multivariable logistic regression models.ResultsThere were no significant differences in self-reported NSAID use between all BE cases and all controls (58.2% vs 54.6%; P = .33); this was seen for aspirin products (43.0% vs 37.4%; P = .08) and nonaspirin NSAIDs (7.7% vs 8.9%; P = .46). These findings persisted in the multivariable model for any NSAIDs (adjusted OR, 0.89; 95% CI, 0.75-1.28), aspirin (adjusted OR, 1.16; 95% CI, 0.90-1.51), and nonaspirin NSAIDs (adjusted OR, 0.88; 95% CI, 0.55-1.39). Use of a combination of aspirin and nonaspirin NSAIDs was reported in 7.4% of cases and 8.3% of controls, and a nonsignificant inverse association with BE was seen (adjusted OR, 0.70; 95% CI, 0.44-1.11). There was no significant association between BE and daily NSAID use (adjusted OR, 1.03; 95% CI, 0.78-1.37). Similar findings were observed for comparisons involving nondysplastic or dysplastic BE cases, and endoscopy or primary care control groups separately or combined.ConclusionsThe use of NSAIDs was not associated with a reduced risk of BE. It is likely that the protective mechanism of NSAIDs on EAC occurs subsequent to the development of BE.

Project description:As the premalignant lesion of human esophageal adenocarcinoma (EAC), Barrett's esophagus (BE) is characterized by intestinal metaplasia in the normal esophagus (NE). Gene expression profiling with microarray and serial analysis of gene expression (SAGE) may help us understand the potential molecular mechanism of human BE.We analyzed three microarray datasets (two cDNA arrays and one oligonucleotide array) and one SAGE dataset with statistical tools, significance analysis of microarrays (SAM) and SAGE(Poisson), to identify individual genes differentially expressed in BE. Gene set enrichment analysis (GSEA) was used to identify a priori defined sets of genes that were differentially expressed. These gene sets were grouped according to either certain signaling pathways (GSEA curated), or the presence of consensus binding sequences of known transcription factors (GSEA motif). Immunohistochemical staining (IHC) was used to validate differential gene expression.Both SAM and SAGE(Poisson) identified 68 differentially expressed genes (55 BE genes and 13 NE genes) with an arbitrary cutoff ratio (> or =4-fold). With IHC on matched pairs of NE and BE tissues from 6 patients, these genes were grouped into 6 categories: category I (25 genes only expressed in BE), category II (5 genes only expressed in NE), category III (8 genes expressed more in BE than in NE), and category IV (2 genes expressed more in NE than in BE). Differential expression of the remaining genes was not confirmed by IHC either due to false discovery (category V), or lack of proper antibodies (category VI). Besides individual genes, the TGFbeta pathway and several transcription factors (CDX2, HNF1, and HNF4) were identified by GSEA as enriched pathways and motifs in BE. Apart from 9 target genes known to be up-regulated in BE, IHC staining confirmed up-regulation of 19 additional CDX1 and CDX2 target genes in BE.Our data suggested an important role of CDX1 and CDX2 in the development of BE. The IHC-confirmed gene list will lead to future studies on the molecular mechanism of BE.
