Figure 1 Results for Epstein-Barr virus infection by in situ hybridization and for microsatellite instability, E-cadherin, and p53 expression by immunohistochemistry in remnant gastric cancer and primary gastric cancer patients. A: Remnant gastric cancer; B: Primary gastric cancer. EBV: Epstein-Barr virus; MSI: Microsatellite instability; NA: No alteration.
