RT Journal Article SR Electronic T1 Lung cancer for the non-respiratory physician JF Clinical Medicine JO Clin Med FD Royal College of Physicians SP e578 OP e583 DO 10.7861/clinmed.2021-0657 VO 21 IS 6 A1 Emma O'Dowd A1 Joe Mackenzie A1 Haval Balata YR 2021 UL http://www.rcpjournals.org/content/21/6/e578.abstract AB Lung cancer continues to be the leading cause of cancer death globally. Delayed diagnosis is a major contributing factor to poor outcomes and remains a key challenge to overcome. While debate around the implementation of lung cancer screening for asymptomatic high-risk individuals continues, rapid access to relevant diagnostic tests is essential. The new National Optimal Lung Cancer Pathway describes ‘diagnostic standards of care’ in an effort to implement best practice, reduce variation and improve delays in diagnosis, staging and treatment of lung cancer. Lung cancer treatment continues to develop with new surgical techniques, radiotherapy options and more drugs being licensed as part of standard treatment. We provide an overview of the core lung cancer diagnostic steps, recognition and management of acute presentations as well as the latest treatment options.
