In multivariable models adjusted for common prognostic factors, high serum TNF levels were associated with worse overall survival [adjusted HR for high (vs. low) 1.49; 95% Cl, 1.01–2.20; PTrend = 0.045], high serum IL5 levels were associated with better cancer-specific survival [adjusted HR for high (vs. low) 0.61; 95% Cl, 0.38–0.99; PTrend = 0.045], and a higher Th1:Th2 produced cytokine index was associated with worse cancer-specific survival [adjusted HR for high (vs. low) 1.71; 95% Cl, 1.04–2.81; PTrend = 0.036]. Here, TNF is linked to cancer.
