IL-8 remained a significant predictor of OS in multivariable analysis adjusting for age, cancer group, gender, and race for OS (HR: 0.19 (95% CI: 0.05 to 0.70), p=0.01), as well as when adding obesity to the analysis (HR: 0.25 (95% CI: 0.07 to 0.94), p=0.04), though it showed a trend toward significance in multivariable analysis for PFS (HR: 0.55 (0.30–1.00), p=0.05).
