Survival curve analysis showed that patients undergoing AC had similar OS (a. p = 0.052) and better DFS (b. p = 0.046) than those who did not undergo AC. For the patients with PNI, the patients who underwent AC had better OS (c. p = 0.022) and DFS (d. p = 0.027) than those who did not undergo AC. For the patients without PNI, the OS (e. p = 0.564) and DFS (f. p = 0.47) of patients with PNI and who did not undergo AC were similar
