Survival analysis based on histologic features and pathologic stage. (A) Survival comparisons based on histology in bilateral multiple primary lung cancer patients without N2 metastasis (n = 99), indicating that patients with bilateral adenocarcinoma (Ad-Ad) had a significantly better overall survival than patients with bilateral squamous cell carcinoma (Sq-Sq), but not between the Ad-Ad and different histologic types (DH) subgroups or between Sq-Sq and different histologic types subgroups. (B) Survival comparison according to the largest postoperative T (pT) stage (n = 101), showing that patients with largest T1 stage had significantly better overall survival than those with T2, and that there were no significant differences between those with T1 and T3 and those with T2 and T3. (C) Survival comparisons based on the highest postoperative N (pN) stage (n = 101), suggesting that patients with N0 had a significantly better overall survival than patients with N1 or N2, but there was not a significant difference between those with N1 and pN2. (D) Survival comparison according to the most advanced pTNM stage (n = 101), demonstrating that the more advanced the stage, the poorer the prognosis.
