It is already known that patients with
chronic obstructive pulmonary disease
(COPD) face a greater risk of dying of lung cancer than age and gender matched controls. According to new research, a
concurrent asthma diagnosis
and the use of inhaled corticosteroids may be associated with a decreased risk of lung cancer in patients with COPD, while the use of acetylsalicylic acid may be linked to an increased risk.
aimed to analyze whether age, gender, socioeconomic factors, comorbidity, and medication may affect the risk of lung cancer in patients with COPD. Data was collected from primary care medical records and national patient registries in Sweden.
“Both COPD and lung cancer are closely related to the chronic inflammation and oxidative stress induced by smoking,” the study explained. “However, it has been shown that patients with emphysema who have never smoked also have an increased risk of developing lung cancer. Hence, it is likely that the inflammatory process driving the formation of emphysema contributes as a risk factor for lung cancer.”
