Figure 4 Kaplan-Meier overall survival estimates stratified for pathological T classification in 47 patients who underwent an no residual tumor resection. The median overall survival (OS) was not reached with a 5-year OS rate of 100% in patients with pathological T1 (pT1) disease. The median OS was not reached with a 5-year OS rate of 83% in pT2 patients, whereas it was 10 mo with a 5-year OS rate of 22% in pT3-4 patients. OS differed significantly among the groups (P < 0.001).
