Background: Missed oesophageal cancer (MEC) at upper gastrointestinal endoscopy (UGE) is poorly documented. Objective: The objectives of this study were: (1) to assess the rate, predictors and survival of MEC; (2) to compare MEC and non-MEC tumours. Methods: This was a retrospective cohort study conducted at four tertiary centres. Oesophageal cancers (ECs) diagnosed between 2008 and 2015 were included. Patients with a premalignant condition (Barrett, achalasia), prior diagnosis of EC or oesophagogastric junction tumour of gastric origin were excluded. MEC was defined as EC detected within 36 months after negative UGE. Results: 123,395 UGEs were performed during the study period, with 502 ECs being diagnosed (0.4%). A total of 391 ECs were finally included. Overall MEC rate was 6.4% (95% confidence intervals (CI): 4.4-9.3%). The interval between negative and diagnostic UGE was less than 2 years in 84% of the cases. Multivariate analysis showed that a negative endoscopy was associated with proton pump inhibitor (PPI) therapy and less experienced endoscopists. MEC was smaller than non-MEC at diagnosis (25 versus 40 mm, p ¼ 0.021), more often flat or depressed (p ¼ 0.013) and less frequently diagnosed as metastatic disease (p ¼ 0.013). Overall 2-year survival rate was similar for MEC (20%) and non-MEC (24.1%) (p ¼ 0.95). Conclusions: MEC accounted for 6.4% of all ECs and was associated with poor survival. High-quality UGE and awareness of MEC may help to reduce its incidence.

In an area of high antibiotic resistance to H. pylori, 10-day Pylera plus double-dose PPI emerged as an alternative as third-line therapy, although not achieving optimal eradication rates. TRAEs were common but were neither severe nor did they condition compliance.
