Figure 4From: Elevated expressions of survivin and VEGF protein are strong independent predictors of survival in advanced nasopharyngeal carcinomaA, Kaplan-Meier curve showing the patients with survivin over-expression have a lower suvivial rate than those with survivin low-expression (P = 0.0006). B, no significant difference of 5-year survival rate was found between survivin over-expression and low-expression in NPC patients with early stage (stage I/II, P = 0.7136). C, significant difference of 5-year survival rate was found between survivin over-expression and low-expression in NPC patients with advanced stage (stage III/IV, P = 0.0002)Back to article page
