Comparison of the recurrence-free survival curves.
Notes: (A) Patients with MVI positivity combined with high KI-67 show shorter RFS compared with patients with MVI positivity combined with low KI-67. (B) Patients with MVI negativity combined with high KI-67 show no difference compared with patients with MVI negativity combined with low KI-67 in terms of RFS. (C) Patients with MVI positivity combined with high KI-67 show shorter RFS compared with patients with MVI negativity combined with high KI-67. (D) Patients with MVI positivity combined with high KI-67 show shorter RFS compared with patients with MVI negativity combined with low KI-67. (E) Patients with MVI positivity combined with low KI-67 show no difference compared with patients with MVI negativity combined with high KI-67 in terms of RFS. (F) Patients with MVI positivity combined with low KI-67 show no difference compared with patients with MVI negativity combined with low KI-67 in terms of RFS. MVI positivity/high KI-67: MVI positivity and high KI-67 positive cellular index; MVI positivity/low KI-67: MVI positivity and low KI-67 positive cellular index; MVI negativity/high KI-67: MVI negativity and high KI-67 positive cellular index; MVI negativity/low KI-67: MVI negativity and low KI-67 positive cellular index. Results are from Kaplan–Meier analysis. P<0.05 was considered to be statistically significant.
