Abstract

Purpose: While adherence to the World Cancer Research Fund (WCRF) guidelines on lifestyle and cancer was recently proven to be associated with an increased risk of esophageal cancer, no investigation has yet been carried out on its role on Barrett’s esophagus (BE) development and its progression to esophageal adenocarcinoma (EAC). The primary aim of this study was to evaluate the role of adherence to WCRF lifestyle recommendations in BE onset and progression. The secondary aim was to investigate the association between disease progression and specific aspects of diet and lifestyle. Methods: Established risk factors for BE and EAC development and adherence to WCRF guidelines were assessed in 107 consecutive patients undergoing an upper gastrointestinal endoscopy for symptoms suggesting gastroesophageal reflux (GERD) and a suspected diagnosis of BE/dysplasia on BE. Patients were divided according to histology: those with GERD without metaplasia, with non-dysplastic BE, with low-grade dysplasia, with high-grade dysplasia or with early EAC. The four groups were expressed as an ordered categorical variable of disease progression. An ordered logit model was estimated to identify the independent predictors of disease progression. Results: Adherence to WCRF guidelines was identified as independent protective factor (OR 0.51, 95 % CI 0.37–0.67) of disease progression. Disease progression was associated with reduced adherence to guidelines on physical activity (from 48.2 to 5.3 %, p = 0.001), sedentary habits (from 33.3 to 0 %, p = 0.03), fruit consumption (from 37.0 to 5.6 %, p = 0.02) and processed meat consumption (from 51.9 to 10.5 %, p = 0.002). Conclusion: Adherence to WCRF guidelines has a protective factor in BE onset and its evolution to EAC.
