According to the World Health Organization (2016), chronic obstructive pulmonary disease (COPD) and lung cancer (along with trachea and bronchial cancers) are third and sixth among 10 top causes of death globally. The association between lung cancer and COPD has been widely established owing to their common endogenous and exogenous risk factors. Mechanistically, lung cancer and COPD are interlinked diseases in many ways such as oxidative stress-associated DNA damage, inflammation, and telomere shortening. An increase in lung cancer has been well correlated with smoking, which is likely to occur up to five folds higher in smokers with COPD than normal lung function subjects. In majority of cases, lung cancer development, especially in COPD patients, is asymptomatic and only diagnosed at advanced stages with poor prognosis. The development of biomarkers for early prediction of lung cancer in both high- and low-risk COPD patients will help clinicians for their better follow-up, early diagnosis, and improved therapeutic management.
