摘要:
Although Epstein-Barr virus (EBV) has been reported to be present in some 7% of gastric carcinomas, the nature of the background gastric mucosa of carcinoma has not been elucidated. The authors evaluated the degree of gastritis in the background gastric mucosa of EBV-associated gastric carcinoma. EBV was detected using in situ hybridization for EBV-encoded small ribonucleic acid 1 (EBER-1) in carcinoma cells. The authors compared gastritis in surgically resected stomachs with 8 EBER-1-positive and 16 EBER-1-negative gastric carcinomas of a similar histologic type using histologic variables of the Updated Sydney System. All eight lesions of EBER-1-positive gastric carcinomas had intestinal metaplasia in the background. Mild to moderate glandular atrophy was common in both groups. Many of the tested lesions, 87.5% of EBER-1-positive and 62.5% of EBER-1-negative lesions, were located near the mucosal atrophic border. The background gastric mucosa for EBV-associated gastric carcinomas is rich in atrophic changes. EBV-associated gastric carcinomas are located near the mucosal atrophic border.
