Kaplan-Meier OS and PFS. (A) OS in the pCR and pRT groups; (B) PFS in the pCR and pRT groups; (C) PFS of patients with different Japanese residual tumor patterns; (D) PFS of patients with different degrees of tumor differentiation; (E) OS of patients with and without lymph node metastasis; (F) PFS of patients with and without lymph node metastasis. Type 1: shallow remnant; type 2: central remnant; type 3: deep remnant; type 4: diffuse remnant. OS, overall survival; PFS, progression-free survival; pCR, pathological complete response; pRT, pathological residual tumor.
