Overview
Gastric cancer classifications are Padova classification that classified gastric cancer into five types according tot degree of dysplasia. Japanese classification subdivided gastric cancer according to the atypia degree to five types also.
Classification
Padova classification[1]
| 1. Negative for dysplasia
1.0 Normal 1.1 Reactive foveolar hyperplasia 1.2 Intestinal metaplasia (IM) 1.2.1 IM Complete type 1.2.2 IM Incomplete type |
| 2. Indefinite for dysplasia
2.1 Foveolar hyperproliferation 2.2 Hyperproliferative IM |
| 3. Non-invasive neoplasia (flat or elevated [synonym adenoma])
3.1 Low-grade 3.2 High-grade 3.2.1 Including suspicious for carcinoma without invasion (intreglandular) 3.2.2 Including carcinoma without invasion (intraglandular) |
| 4. Suspicious for invasive carcinoma |
| 5. Invasive adenocarcinoma |
Japanese classification[2]
| Category | Definition |
|---|---|
| Group I | Normal mucosa and benign lesions with no atypia |
| Group II | Lesions showing atypia but diagnosed as benign (non-neoplastic) |
| Group III | Borderline lesions between benign and malignant |
| Group V | Lesions strongly suspected of carcinoma |
| Group V | Carcinoma |
