Fig. 4: Kaplan–Meier curves showing the survival probability for the different tumor groups.

From: T3 versus T4a staging challenges in deeply invasive colonic adenocarcinomas and correlation with clinical outcomes

(a) Kaplan-Meier curve for the entire cohort of patients; (b) Kaplan-Meier curve for the lymph node-negative subset of the three groups; (c) Kaplan-Meier curve for the entire cohort of patients with Group 2 further divided into Groups 2a and 2b. (Group 1—pT4a colonic adenocarcinoma at the serosal surface; Group 2—Deeply invasive colonic adenocarcinoma ≤1 mm from the serosal surface {2a—separated by fibrosis; 2b—separated by contiguous inflammation}; Group 3—pT3 colonic adenocarcinoma >1 mm from the serosal surface).
