Figure 2.
Kaplan-Meier curves for overall survival rate by clinical stage and surgical margin.
(A)The survival rate for those with clinical stage IV tumors was significantly lower than those with clinical stage I and II, p<0.001 and p = 0.013 respectively. (B) The survival rate for those with a positive surgical margin was significantly lower than those with negative surgical margin, p<0.001.

Kaplan-Meier curves for disease progression-free rate by clinical stage and surgical margin.
(A)The disease progression-free rate for those with clinical stage IV was significantly lower than those with clinical stage I and II disease, p = 0.003 and p = 0.014 respectively. (B)The disease progression-free rate for those with positive surgical margin was significantly lower than those with negative surgical margin, p<0.001.
