title: Influence of obesity and bariatric surgery on gastric cancer.
abstract: Esophageal and gastric cancer (GC) are related to obesity and bariatric surgery. Risk factors, such as gastroesophageal reflux and Helicobacter pylori, must be investigated and treated in obese population. After surgery, GC reports are anecdotal and treatment is not standardized. This review aims to discuss GC related to obesity before and after bariatric surgery.
