Input (English): Question: Is preoperative Helicobacter pylori Infection Associated with Increased Survival After Resection of Gastric Adenocarcinoma?
Answer: Patients with and without preoperative H. pylori infection had few differences in adverse pathologic features at the time of gastric adenocarcinoma resection. Despite similar disease presentations, preoperative H. pylori infection was independently associated with improved OS. Further studies examining the interaction between H. pylori and tumor immunology and genetics are merited.
