Compared to healthy volunteers, the levels of IP-10, MIP-1α, MIP-1β, MIP-2, and TNF-α were significantly higher in lung cancer patients (45.5 (37.1–56.7): 57.2 (43.0–76.5), 34.4 (21.8–75.2): 115.4 (96.6–191.2), 49.3 (25.6–78.7): 160.5 (124.9–218.6), 22.6 (17.8–31.2): 77.9 (50.1–186.5), 3.80 (2.3–6.2): 10.3 (5.7–16.6)), but the level of IFN-γ was decreased in lung cancer patients (12.38 (9.1–27.8): 5.9 (3.5–9.7)). The gene discussed is CCL4; the disease is lung cancer.
