Advances in the prevention and treatment of lung cancer

Abstract

Lung cancer remains the most common fatal malignancy in the Western world. Survival rates have only improved modestly over the past three decades and new approaches are urgently required. It is clear that a concerted effort to reduce cigarette smoking is required. However, about 10% of patients with lung cancer are never smokers, indicating genetic or other predisposition. Lung cancer screening programmes are being trialled to target high-risk populations. Genetic strategies will provide new methods for screening and predicting response to treatment. Current therapy for lung cancer has reached a plateau and novel agents have shown modest clinical efficacy. Understanding the mechanisms by which chronic inflammatory disorders such as chronic obstructive pulmonary disease contribute to lung cancer development will help to identify new biological targets and biomarkers of early disease. This review focuses on recent advances in lung cancer prevention and treatment. © 2011 Royal College of Physicians of Edinburgh.
