Also, systemic levels of IL-1β (1.9 (0.6–3.4) vs. 1.9 (1.1–4.8) pg/mL, p = 0.211), IL-4 (11.5 (9.5–26.6) vs. 11.5 (11.5–37.3) pg/mL, p = 0.536), IL-6 (3.8 (1.8–9.8) vs. 3.8 (1.4–8.4) pg/mL, p = 0.719), IL-11 (0 (0–5.9) vs. 0 (0–37.2) pg/mL, p = 0.249), TNF-α (11.7 (6.7–20.9) vs. 11.4 (7.8–17.1) pg/mL, p = 0.540) and VEGF (137.0 (81.7–241.1) vs. 160.8 (81.7–376) pg/mL, p = 0.819), respectively, were not significantly different between tumor grades. The gene discussed is IL6; the disease is neoplasm.
