Additional file 2 The Kaplan-Meier curves of stage III patients before and after MPA. Kaplan-Meier analyses of oncologic outcomes (extracted stage III patients). The oncologic outcomes of patients who did (cx+) or did not (cx-) receive neoadjuvant chemotherapy were compared (red curve: cx + group, black curve: cx- group). a–c: outcomes before propensity-score matching (n = 147); d–f: outcomes after propensity-score matching (n = 52). Triangles indicate the censored cases. (a) The overall survival of patients with/without chemotherapy before propensity-score matching. (b) The local control rate of patients with/without chemotherapy before propensity-score matching. (c) The distant progression-free survival of patients with/without chemotherapy before propensity-score matching. (d) The overall survival of patients with/without chemotherapy after propensity-score matching. (e) The local control rate of patients with/without chemotherapy after propensity-score matching. (f) The distant progression-free survival of patients with/without chemotherapy after propensity-score matching.
