Overview
Adenocarcinoma of the lung may be classified according to WHO into many subtypes. Adenocarcinoma of the lung may be classified according to IASLC/ATS/ERS into pre-invasive lesions, atypical adenomatous hyperplasia, adenocarcinoma in situ, minimally invasive adenocarcinoma, invasive adenocarcinoma, and variants of invasive adenocarcinoma.
Classification
- Adenocarcinomas are highly heterogeneous tumors.
- Several major histological subtypes are currently recognized by the WHO and IASLC/ATS/ERS classification systems.[1][2][3]
- The IASLC/ATS/ERS lung adenocarcinoma histological classification system was proposed in 2011.[4]
- According to this new classification, tumor size ≤3 cm with pure lepidic pattern, but without lymphatic, vascular, pleural invasion or tumor necrosis was defined as adenocarcinoma in situ (AIS).
- If tumor size ≤3 cm with a lepidic predominant pattern and contained ≤5 mm stromal invasion it was defined as minimally invasive adenocarcinoma (MIA).
- If tumor had >5 mm stromal invasion it was defined as an invasive adenocarcinoma.
- The WHO histological classification of adenocarcinoma is following:[5][6]
| WHO Classification of Lung Tumors | |
|---|---|
| Histological type | Subtype |
| Epithelial tumors | |
| Adenocarcinoma |
