Though Barrett’s esophagus is rare in pediatric gastroenterology, concerns about esophageal cancer are fairly frequent. In addition, some conditions that increase the risk of esophageal adenocarcinoma start in childhood.
One way to lessen the risk of Barrett’s esophagus in adults is through the use of medications (Gastroenterology 2012; 142: 442-52). This study was a pooled analysis of six population-based trials with a total of 1226 esophageal adenocarcinoma (EAC) patients and 1140 esophagogastric junctional adenocarcinoma (EGJA) patients. NSAIDs (aspirin and nonaspirin) lowered the risk of both EAC and EGJA, with OR of 0.68 and 0.83 respectively.
Although this study suggests a possible role for NSAIDs in preventing cancer in patients with Barrett’s esophagus, the risks and benefits for this intervention need to be individualized.
