Figure 1.

Survival curves for patients with different tumor T stages (A), different vascular invasions (B), and different local recurrence rates (C). The survival rate for the patients with T0 (n = 28), T1 (n = 48), T2 (n = 26), T3 (n = 4) varied significantly (P = 0.022). Patients without vascular invasion (n = 103) had a higher survival rate than those with vascular invasion. (n = 3) (P = 0.01). Patients without local recurrence (n = 88) had a higher survival rate than those with local recurrence (n = 18) (P = 0.005).
