Invasive adenocarcinoma is a malignant epithelial tumor showing glandular differentiation, mucin production, or “pneumocyte marker” expression determined by immunohistochemistry (IHC). Patterns of glandular differentiation which are associated with adenocarcinoma subtypes are lepidic, acinar, papillary, micropapillary, and solid.
Incidence and Etiology
Lung cancer in general is the commonest cause of lung cancer globally, and adenocarcinoma is the most common form of lung cancer in global terms. In the USA, the lung cancer incidence rate is approximately 35 cases per 100,000 person-years, but such figures are of questionable value given the considerable variations, largely due to regional variance in tobacco consumption. In several European countries, this figure can...
