Rationale: We performed this retrospective study to clarify the clinical characteristics, survival and mortality predictors in patients with combined pulmonary fibrosis and emphysema (CPFE) and lung cancer. Methods: We retrospectively reviewed the medical records of a total of 123 patients with lung cancer, as confirmed according to histological or cytological examinations. Based on the findings of chest CT, the patients were categorized into four groups: LC+normal (n=70); LC+emphysema (n=26); LC+fibrosis (n=10); LC+CPFE (n=17). The clinical characteristics and survival of the LC+CPFE group were compared with those of the other groups. In addition, mortality predictors were evaluated in the LC+CPFE group. Results: The proportion of females was significantly higher in the LC+normal group than in the LC+CPFE and LC+emphysema groups. Significantly more patients were diagnosed with squamous cell carcinoma in the LC+CPFE group than in the LC+normal group. The proportion of patients whose primary mass was located in “nonsubpleural” areas was significantly higher in patients with CPFE who also had lung cancer in the upper lobe than in those with CPFE who also had lung cancer in the other sites. There were significant differences in survival between the LC+normal group and the other groups, whereas there were no significant differences in survival among the LC+emphysema, LC+fibrosis and LC+CPFE groups. In the LC+CPFE group, the patients with a high level of serum KL-6 at diagnosis and upper lobe lung cancer demonstrated a high risk of death. A high level of serum KL-6 at diagnosis was also independently associated with a high risk of death. Conclusions: Patients with CPFE and lung cancer may have distinct clinical characteristics. Strict follow-up is required in patients with CPFE and lung cancer whose serum KL-6 level at diagnosis is higher than the normal range and/or the primary mass of lung cancer is located in the upper lobe.
