minimally invasive adenocarcinoma of the lung; pulmonary MIA

Definition: The International Association for the Study of Lung Cancer/American Thoracic Society/European Respiratory Society and 2015 WHO classifications of lung adenocarcinoma recommend designating tumors showing entirely lepidic growth as adenocarcinoma in situ (AIS) and lepidic tumors with invasion less than or equal to 5 mm as minimally invasive adenocarcinoma (MIA), both of which have superior outcome to conventional invasive adenocarcinoma (IA).
