There are many common classification of gastric cancer can be classified according to different standards of conduct related to the classification of gastric cancer.
A common classification of gastric cancer, pathological classification and classification: general classification can be divided into bacteria umbrella, ulcer type, infiltrating type.
1, early gastric cancer : protruding, superficial type (superficial protruding, superficial flat and superficial depressed), depressed, mixed with advanced gastric cancer: Borrman I type (polypoid), Borrman II type (limited ulceration), Borrman type (infiltration ulceration), Borrman type (diffuse infiltrating type)
2, advanced gastric cancer: cancer invasion of muscularis or serosa layers.
Categories of common cancer, histological type of gastric cancer sub-type National Collaborative Group World Health Organisation (WHO) and the Japanese classification of gastric cancer will be the situation in our country, the histological type of early gastric cancer classified as: the Ministry of papillary adeno , tubular adenocarcinoma (well differentiated and moderately differentiated), poorly differentiated adenocarcinoma, signet ring cell carcinoma, adenocarcinoma, mucosa, hard carcinoma, unclassified carcinoma and mixed carcinoma.
1. Common types of papillary adenocarcinoma, tubular adenocarcinoma, poorly differentiated adenocarcinoma, mucinous adenocarcinoma, signet-ring cell carcinoma.
2. Special type of adenosquamous carcinoma, squamous cell carcinoma, carcinoid, undifferentiated carcinoma, gastric cancer.
3. Lauren's classification based on morphology and histochemistry, the histological type into intestinal type and diffuse type of two types. The results show that: a higher degree of intestinal differentiation, more common in the elderly, the low degree of malignancy, prognosis good; and diffuse the opposite.
