| Outline of Final Research Achievements |
We focused on CD3+ tumor-infiltrating lymphocytes (CD3+ TILs), neutrophil-lymphocyte ratio (NLR), and fibrinogen in this study. The numbers of CD3+ TILs in patients with gastric cancer were lower than those in gastric adenoma. Moreover, CD3+ TILs was inversely correlated with tumor progression and prognosis in patients with gastric cancer. On the other hand, the values of NLR and fibrinogen were significantly correlated with advanced disease. Patients with high NLR and fibrinogen status had poorer prognosis than those with low status. Consequently, our findings suggest that the systemic inflammatory response induced by tumor cells suppress host immune response and its escape mechanism from host immune surveillance produces tumor invasion and metastases.
