Figure 2.

Change of different blood counts during radiotherapy (RT). The figure shows the dynamics of (A) total white blood cell (WBC), (B) neutrophil, (C) monocyte, (D) lymphocyte, and (E) platelet counts; and (F) hemoglobin before, during, and after radiation (pre-RT, during-RT, immediately post-RT, and 1–3 months after RT). There were significant reductions in the level of peripheral lymphocyte counts (PLC), total white blood cell, neutrophil, platelet, and monocyte counts (P<0.001), while hemoglobin increased. The reduction of PLC was the most obvious among these peripheral blood cells in complete blood counts (CBC) after radiation. The lowest PLC (nadir-PLC) was at the end of radiation (post-RT).
