Primary lung cancer is the leading cause of cancer-related deaths in industrialized countries. Despite advances in treatment, the overall 5-year survival remains poor due to the advanced stage of disease at presentation. Smoking remains the main risk factor being responsible for around 85% of all cases. The most important distinction is that between non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). Surgeons primarily deal with NSCLC (SCLC is an aggressive tumour that usually presents with systemic disease). NSCLC has a number of histological subtypes.Patient evaluation aims to establish the cell type of the tumour, determine the stage of the disease, and to determine fitness for surgery. Staging of NSCLC is based on the tumour/node/metastasis (TNM) classification. Procedures used to diagnose or stage lung cancer can include chest X-ray, chest computed tomography (CT) scan, combined positron emission tomography/CT, CT or transbronchial guided needle biopsy, and mediastinoscopy amongst others. Surgery is the only established method for ‘curing’ NSCLC. However, only a quarter of patients have resectable disease at presentation. Surgical resection can be performed using a variety of procedures including lobectomy, pneumonectomy or wedge resections. The 5-year survival of patients with stage I lung cancer following surgical resection is 51–60%.
