IL6 and neoplasm: Correlation analysis by the Spearman test showed a significant association between objective tumor response and NLR (R = 0.554; 95% CI: 0.437 to 0.653, p < 0.0001), CRP (R = 0.4549; 95% CI: 0.3163 to 0.5745; p < 0.0001), IL-6 (R = 0.254; 95% CI: 0.0554 to 0.3646; p = 0.0088), ferritin (R = 0.210; 95% CI: 0.0498 to 0.3597; p = 0.0107), and mGPS (R = 0.229; 95% CI: 0.0765 to 0.370, p = 0.0036) after three NACT cycles.
