As shown in Table 5, PD-L1 expression of CPS≥10 was significantly related to age (CPS≥10 vs. CPS<10: 60.3 ± 11.3 vs. 56.1 ± 12.8, p<0.001), tumor size≥5 cm (CPS≥10 vs. CPS<10: 37.7% vs. 26.0%, p<0.001), Lauren classification (CPS≥10 vs. CPS<10: intestinal/diffuse/mix: 25.6%/56.1%/18.3% vs. 29.9%/58.2%/11.9%, p=0.049), CD-31 positivity (CPS≥10 vs. CPS<10: 28.0% vs. 19.7%, p=0.010), EBV positivity (CPS≥10 vs. CPS<10: 10.7% vs. 1.2%, p<0.001), dMMR status (CPS≥10 vs. CPS<10: 8.8% vs. 4.8%, p=0.015), and the Ki-67 index (CPS≥10 vs. CPS<10: 64.7% ± 22.9% vs. 53.7% ± 23.9%, p<0.001). This evidence concerns the gene PECAM1 and neoplasm.
