Figure 1. — Average ratios of Foxp3⁺ cells/CD4⁺ cells in the PBLs, RLNLs and TILs in patients with non-small cell lung cancer. The average ratios of Foxp3⁺ cells/CD4⁺ cells in the PBLs, RLNLs and TILs were 2.8, 4.4 and 10.4%, respectively. The number of Tregs in the RLNLs was significantly higher than that in the PBLs, and the number of Tregs in the TILs was significantly higher than that in the RLNLs. PBL, peripheral blood lymphocyte; RLNL, regional lymph node lymphocyte; TIL, tumor-infiltrating lymphocyte.
