Abstract Background Chronic obstructive pulmonary disease (COPD) and lung cancer are associated diseases. COPD is underdiagnosed and thus undertreated, but there is limited data on COPD diagnosis in the setting of lung cancer. We assessed the diagnosis of COPD with lung cancer in a large public healthcare system. Methods Anonymous administrative data was acquired from ICES, which links demographics, hospital records, physician billing, and cancer registry data in Ontario, Canada. Individuals age 35 or older with COPD were identified through a validated, ICES-derived cohort and spirometry use was derived from physician billings. Statistical comparisons were made using Wilcoxon rank sum, Cochran-Armitage, and chi-square tests. Results From 2002 to 2014, 756,786 individuals were diagnosed with COPD, with a 2014 prevalence of 9.3%. Of these, 51.9% never underwent spirometry. During the same period, 105,304 individuals were diagnosed with lung cancer, among whom COPD was previously diagnosed in 34.9%. Having COPD prior to lung cancer was associated with lower income, a rural dwelling, a lower Charlson morbidity score, and less frequent stage IV disease (48 vs 54%, p < 0.001). Spirometry was more commonly undertaken in early stage disease (90.6% in stage I-II vs. 54.4% in stage III-IV). Conclusion Over a third of individuals with lung cancer had a prior diagnosis of COPD. Among individuals with advanced lung cancer, greater use of spirometry and diagnosis of COPD may help to mitigate respiratory symptoms.

Objective. The aim of this study was to establish C-reactive protein (CRP) levels in serum of patients with lung cancer and chronic obstructive pulmonary disease (COPD) and evaluate the associations of CRP levels with clinicopathological characteristics. Materials and Methods. In total, 140 persons were included in the study: 43 patients with lung cancer, 34 patients with lung cancer and COPD, 42 patients with COPD, and 21 healthy subjects. CRP analysis was performed with a serum protein analyzer using commercially available highsensitivity reagent kits. Results. The C-reactive protein levels were significantly higher in the lung cancer patients with or without COPD compared with the COPD patients or the control group (20.42±1.95 and 22.49±2.31 vs. 8.37±0.91 and 2.49±0.47 mg/L, respectively; P<0.01). The patients with advanced lung cancer had higher CRP levels compared with the patients suffering from early stage lung cancer (23.11±1.72 vs. 14.59±2.23 mg/L, P<0.01). The CRP levels were significantly higher in the patients with early stage lung cancer compared with the COPD patients (14.59±2.23 mg/L vs. 8.37±0.91 mg/L, P<0.05). No association was found between CRP and histology, lung function, and smoking status in the patients with lung cancer. Conclusions. Chronic inflammation plays an important role in both diseases: lung cancer and COPD. However, it seems that inflammation is more pronounced in patients with lung cancer, as the CRP levels were significantly higher in these patients than other groups.

Disease Epidemiology

Chronic obstructive pulmonary disease (COPD), the frequently fatal pathology of the respiratory tract, accounts for half a billion cases globally. COPD manifests via chronic inflammatory response to irritants, frequently to tobacco smoke. The progression of COPD from early onset to advanced disease leads to the loss of the alveolar wall, pulmonary hypertension, and fibrosis of the respiratory epithelium. Here, we focus on the epidemiology, progression, and biomarkers of COPD with a particular connection to lung cancer. Dissecting the cellular and molecular players in the progression of the disease, we aim to shed light on the role of smoking, which is responsible for the disease, or at least for the more severe symptoms and worse patient outcomes. We summarize the inflammatory conditions, as well as the role of EMT and fibroblasts in establishing a cancer-prone microenvironment, i.e., the soil for ‘COPD-derived’ lung cancer. We highlight that the major health problem of COPD can be alleviated via smoking cessation, early diagnosis, and abandonment of the usage of biomass fuels on a global basis.
