CD3 + Tim-3 + T cells were also expressed at elevated levels in gastric secondary peritoneal neoplasm patients’ peripheral blood, respectively compared with colon group and gynecology group (2.52% vs. 1.50%; p = 0.048; 2.52% vs. 1.22%; p = 0.021, Fig. 5B). This evidence concerns the gene HAVCR2 and peritoneal neoplasm.
