Abstract
Epstein-Barr virus-associated gastric carcinoma (EBVaGC) frequently harbors dense lymphocytic infiltration, suggesting a specific microenvironment allowing coexistence with tumor immunity. CD47, which mediates the “do not eat me” signal in innate immunity, is also important in adaptive anti-tumor immunity. We investigated the significance of CD47 in EBVaGC compared with EBV-negative gastric cancer and the correlation with various immune cells. By immunohistochemistry of CD47, high, low, and negative expression was observed in 24, 63, and 12% of EBVaGC (n = 41), while 11, 49, and 39% of EBV-negative gastric cancer (n = 262), respectively, indicating that high expression of CD47 in cancer cells was significantly frequent and increased in EBVaGC (P = 0.043). In contrast to EBV-negative gastric carcinoma in which no significant correlation was observed between CD47 and survival, high expression of CD47 correlated significantly with worse disease-specific survival (P = 0.011) and overall survival (P = 0.013) in EBVaGC. To further clarify the role of CD47 expression in EBVaGC, digital image analysis of immune cell infiltration revealed that high CD47 expression was correlated with a lower ratio of CD8+/Foxp3+ T cells (P = 0.021), a sensitive indicator of tumor immunity. Thus, CD47 lowers anti-tumor immunity in EBVaGC by finely tuning profile of infiltrating T cells, suggesting that CD47 is an additional target for cancer immunotherapy against this virus-driven gastric cancer.
