Combined pulmonary fibrosis and emphysema (CPFE) is a unique disorder. The aim of this study was to compare the surgical outcomes of lung cancer patients with CPFE and those with idiopathic pulmonary fibrosis (IPF) without emphysema.A total of 1548 patients who underwent surgery for primary lung cancer between January 2001 and December 2012 were retrospectively reviewed.Of the 1548 patients, 55 (3.6%) had CPFE on computed tomography (CT), and 45 (2.9%) had IPF without emphysema. The overall and disease-free 5-year survival rates for patients with CPFE were not significantly worse than those for patients with IPF without emphysema (24.9% vs. 36.8%, p = 0.814; 39.8% vs. 39.3%, p = 0.653, respectively). Overall, 21 (38.1%) patients with CPFE and nine patients (20.0%) with IPF without emphysema developed postoperative cardiopulmonary complications. Patients with CPFE had significantly more postoperative cardiopulmonary complications involving pulmonary air leakage for >6 days, hypoxemia, and arrhythmia than patients with IPF without emphysema (p = 0.048).There was no significant difference in survival after surgical treatment between CPFE patients and IPF patients without emphysema, but CPFE patients had significantly higher morbidity than IPF patients without emphysema.
