Data are presented as mean ± standard deviation
§ P < 0.05: data show statistical difference between time point 3 and 2; # P < 0.05: data show statistical difference between time point 4 and 3
Time point 1: before CCRT; Time point 2: at the end of 2nd week of CCRT; Time point 3: at the end of 4th week of CCRT; Time point 4: immediately after CCRT completion
