    Abstract:
    PURPOSE: Screening for esophageal adenocarcinoma (EAC) has not become policy in part over concerns in identifying the high-risk group. It is often claimed that a significant proportion of patients developing EAC do not report preexisting reflux symptoms or prior treatment for gastroesophageal reflux disease (GERD). As such, our aim was to assess the prevalence of GERD symptoms, proton pump inhibitor (PPI) use and Barrett's esophagus (BE) and their impact on survival in patients undergoing esophagectomy for EAC. METHODS: The study population consisted of 345 consecutive patients who underwent esophagectomy for EAC between 2000 and 2011 at a university-based medical center. Patients with a diagnosis of esophageal squamous cell carcinoma and those who underwent esophagectomy for benign disease were excluded. The prevalence of preoperative GERD symptoms, defined as presence of heartburn, regurgitation or epigastric pain, PPI use (>6 months) and BE, defined by the phrases "Barrett's esophagus," "intestinal epithelium," "specialized epithelium," or "goblet cell metaplasia" in the patients' preoperative clinical notes were retrospectively collected. Overall long-term and stage-specific survival was compared in patients with and without the presence of preoperative GERD symptoms, PPI use, or BE. RESULTS: The majority of patients (64%; 221/345) had preoperative GERD symptoms and a history of PPI use (52%; 179/345). A preoperative diagnosis of BE was present in 34% (118/345) of patients. Kaplan-Meier survival analysis revealed a marked survival advantage in patients undergoing esophagectomy who had preoperative GERD symptoms, PPI use or BE diagnosis (P ≤ .001). The survival advantage remained when stratified for American Joint Committee on Cancer stage in patients with preoperative PPI use (P = .015) but was less pronounced in patients with GERD symptoms or BE (P = .136 and P = .225, respectively). CONCLUSION: These data show that the oft-quoted statistic that the majority of patients with EAC do not report preexisting GERD or PPI use is false. Furthermore, a diagnosis of BE is present in a surprisingly high proportion of patients (34%). There is a distinct survival advantage in patients with preoperative GERD symptoms, PPI use, and BE diagnosis, which may not be simply owing to earlier stage at diagnosis. Screening may affect survival outcomes in more patients with EAC than previously anticipated.
