Abstract
Cytomegalovirus (CMV) sometimes causes gastritis, especially in immunocompromised patients, but whether CMV gastritis promotes the development of gastric cancer is unknown. Here, we report a case of gastric cancer that developed in the presence of CMV gastritis, which had been present for at least 4 years and was refractory to treatment. An 80-year-old woman had noted epigastric discomfort and appetite loss. Esophagogastroduodenoscopy revealed a shallow geographical ulcer extending from the upper body to the pylorus. Histological findings of the biopsy and serology were suggestive of CMV gastritis. Serum anti-Helicobacter pylori antibody test was positive, suggesting co-infection with CMV and H. pylori. Her gastritis was unimproved with repeated antiviral therapy and eradication of H. pylori. Thirty months later, wide-spread gastric cancer had developed. We suggest the possibility that the addition of chronic inflammation of CMV infection to H. pylori-induced gastritis facilitated the development of gastric cancer.
