Glutathione S-transferase M1 gene polymorphism is related to COPD in patients with non-small-cell lung cancer

摘要

Oxidative stress contributes to the development of both lung cancer and chronic obstructive pulmonary disease (COPD). Antioxidative enzymes may protect against such damage. We hypothesized that genetic variations in glutathione S-transferase M1 and/or T1 genes (GSTM1 and GSTT1, respectively) may influence susceptibility to COPD in patients with non-small-cell lung cancer.
