BCL6 and neoplasm: Univariate analysis showed that compared with the high expression group of BCL6, the low expression group of BCL6 exhibited advanced pN stage (P = 0.013), increased lymph node (LN) metastasis (9.89 ± 9.12 vs. 7.16 ± 11.83, P = 0.001; Fig. 1D), and long tumor diameter (6.81 ± 3.51 vs. 5.38 ± 2.22, P = 0.012; Fig. 1E).
