The dynamic changes of ALCs from baseline (before dCCRT) through week 1–7 during dCCRT and 6 months after the end of dCCRT represented by Tukey box-and-whisker plots. The red dashed line represented the lower limit of normal lymphocyte counts (1.1 × 109/L). ALC absolute lymphocyte count, dCCRT definitive concurrent chemoradiotherapy
