This study aimed to identify outcomes following NAC plus AC for LARC. Patients and Methods: We reviewed 252 patients who underwent curative resection for LARC. Propensity score matching matched 51 patients in NAC and non-NAC groups. Results: Operative time (443 min vs. 286 min, p<0.001), blood loss (279 ml vs. 124 ml p<0.001), and number of patients who received AC were higher in the NAC group (74.5% vs. 33.3%, p<0.001). The Disease control rate of NAC group was 98.1%. The NAC group showed better 3-year RFS (86.5% vs. 62.1%, p=0.021). Patients who received both NAC and AC displayed better 3-year RFS (90.2%) compared to the non-NAC group both with (63.8%) and without (60.4%) AC (p<0.05). Conclusion: NAC and AC for LARC have the potential to improve oncological outcomes. ER -
