Laurén classification
Oncology, staging and radiology
Also known as: Laurén-Klassifikation (Magenkarzinom) · Laurén sınıflaması · Laurén classification of gastric adenocarcinoma
What it is for
Histological classification of gastric adenocarcinoma into two main types by gland formation and cell cohesion.
Classification
| Category | Description |
|---|---|
| Intestinal type | cohesive tumour cells forming glands, resembling intestinal (colorectal-type) adenocarcinoma. |
| Diffuse type | poorly cohesive cells infiltrating the wall singly or in small groups with little or no gland formation. |
| Indeterminate | a minor group fitting neither type (Laurén's original unclassified group). |
| Mixed | later subdivision of the indeterminate group: both intestinal and diffuse components present. |
