Preoperative Chemoradiation in Locally Advanced Rectal Cancer: Efficacy and Safety

Figures

Figure 1. Kaplan-Meier estimates for the study population (n = 40): (A) local control (LC); (B) disease-free survival (DFS); (C) distant metastases-free survival (DMFS); (D) overall survival (OS).

Figure 2. Kaplan-Meier estimates for the study population (n = 40); (A) disease-free survival (DFS) stratified by the response to neoadjuvant CRT; (B) overall survival (OS) stratified by the response to neoadjuvant CRT.

Figure 3. Kaplan-Meier estimates for the study population (n = 40): disease-free survival (DFS) stratified by the total mesorectal excision (TME).
