Other cytokines showing a significant increase in serum from GC patients compared to controls were IL-7 (SMD: 1.04, 95% CI [0.45; 1.63], P=0.0006), IL-10 (SMD: 2.17, 95%CI [0.63; 3.70], P=0.0056), IL-12 (SMD: 2.1, 95%CI [0.91; 3.29], P=0.0056), and TNF-α (SMD: 2.34, 95%CI [0.29; 4.38], P=0.0251). Here, TNF is linked to gastric cancer.
