Figure 2 Kaplan-Maier survival curve. A: Overall survival for patients with pCR or without (pPD) (P = 0.523; χ2 = 3.767); B: Disease-free survival (P = 0.897; χ2 = 2.879). The disease-free survival represented from both local regional recurrences at anastomotic site, mediastinum, celiac trunk, or supraclavicular lymph nodes and distant metastases. OS: Overall survival; DFS: Disease free survival; pCR: Pathological completion response; pPD: Pathological persistent disease.
