From: Prognosis of non-small-cell lung cancer in patients with idiopathic pulmonary fibrosis
Subgroup analysis for survival according to the primary treatment after classifying the patient as GAP ((gender [G], age [A]), and two physiology variables (P) (FVC and DLCO)) stage system) stage and the lung cancer (LC) stage. (a) GAP stage I and LC stages I and II, (b) GAP stage I and LC stage III and IV, (c) GAP stage II and III and LC stage I and II, and (d) GAP stages II and III and LC stage III and IV. In GAP stage I, surgery significantly improved the survival in both early and advanced LC stages (p = 0.023 and p = 0.019). In GAP stages II and III, any treatment modalities failed to significantly improve survival in early or advanced LC stages.
