Update on Lung Cancer

Investigation and treatment of lung cancer has changed dramatically since the last articles in this journal in 2008. These changes include a new study on lung cancer staging, a new tumour, node, metastasis (TNM) classification, linear endoscopic ultrasound as a first-line test for mediastinal staging, investigation and follow-up of ground glass and mixed-lung nodules, radiosurgery for inoperable patients with localized lung tumours, and molecular tests and targeted therapies for advanced non-small cell lung cancer.
