Prognostic utility of lymph node involvement by N stage in patients with resected LS SCLC. (a) The DFS curves of resected SCLC patients with stage pN1 (n = 23) and pN2 (n = 36) by the number of involved lymph nodes. (b) The survival curves of resected SCLC patients with stage pN1 (n = 23) and pN2 (n = 36) by the number of involved lymph nodes. (c) The DFS curves of resected SCLC patients with stage pN1 (n = 23) and pN2 (n = 36) by the numbers of involved lymph node stations. (d) The survival curves of resected SCLC patients with stage pN1 (n = 23) and pN2 (n = 36) by the number of involved lymph node stations.
