Answer to yesterday’s quiz: What percentage of patients with a diagnosis of esophageal cancer do not report symptoms of gastroesophageal reflux disease (GERD)? A. Up to 20%. B. Up to 40%. C. Up to 60%. D. Up to 80%. The answer is B. Population-based case–control and cohort studies indicate that GERD, cigarette smoking, and obesity are the main risk factors for esophageal cancer. The odds that esophageal adenocarcinoma will develop increase by a factor of five for persons with weekly GERD symptoms and by a factor of seven for persons with daily GERD symptoms, as compared with those with less frequent episodes. However, up to 40% of all patients with esophageal cancer do not report GERD symptoms. nej.md/1xUmAND
