MKI67 and neoplasm: Expression of Ki67 in neoplastic cells correlated positively with CTL and Treg counts both within tumor and at the invasive margin (CTLs: R = 0.28, p < 0.005 and R = 0.41, p < 0.001; Tregs: R = 0.42 and R = 0.38, p < 0.001, respectively), Treg percentage at invasion front (R = 0.27, p < 0.007), TIL infiltrate (R = 0.46, p < 0.001), and Treg/Th2 cell percentage ratio (R = 0.29, p < 0.004).
