FIGURE 1.
Kaplan-Meier curves comparing survival for LN+TD−, LN−TD+, and TD+LN+. Overall and 5-year survival was similar for LN+TD− (0.598; 95% CI: 0.593-0.604) and LN−TD+ (0.582; 95% CI: 0.556-0.609), but significantly worse for LN+TD+ (0.415; 95% CI: 0.403-0427) compared with each of the other 2 groups (P<0.001). CI indicates confidence interval; LN, lymph node; TD, tumor deposit.
