The predictive ability of VEGF and the inflammatory biomarkers were compared by ROC curves. (a) The AUCs of VEGF before, during and end of radiotherapy were 0.690 (p < 0.0001), 0.645 (p = 0.003), 0.758 (p < 0.0001) respectively. (b) The AUCs of GPS before, during and the end of radiotherapy were 0.561 (p = 0.212), 0.604 (p = 0.031), 0.571 (p = 0.144) respectively. (c) The AUCs of CAR before, during and the end of radiotherapy were 0.612 (p = 0.021), 0.606 (p = 0.029), 0.578 (p = 0.106) respectively. (d) The AUCs of CLR before, during and the end of radiotherapy were 0.629 (p = 0.008), 0.592 (p = 0.057), 0.655 (p = 0.001) respectively. The red entries represent statistically significant.
