Mark _'s general knowledge of tumour of gastric carcinoma patient serum
The relevant antigen of tumour, are mostly glycolipid or glycoprotein of the macromolecule quantities. The relevant antigen of these tumours can be measured in serum out, a lot of are marked and used as serum tumour by the clinician.
Serum tumour of gastric carcinoma marks to include:
1 CEA
CEA stores in to leather cell and surface of some malignant tumour cells at embryo's mucous membrane of intestines and stomach, it is a kind of glycoprotein. It is not the cancer that CEA raises and can be seen at cancer of colon, gastric carcinoma, pancreas cancer, breast cancer, lung cancer, marrow one kind of cancers and some of thyroid gland. So, the specific difference that CEA diagnoses. Begin to check regularly in 2 to 4 weeks after the operation, contribute to analyzing curative effect, judge that recurs and shifts.
2 CA19 9
9 CA19 one the intersection of form and the intersection of saliva and sour the intersection of ganglion and the intersection of glucoside and ester, the intersection of macromolecule and the intersection of quantity and glycoprotein. Serum CA19 9 levels rise in many kinds of gland cancers. In charge of high cancer sensitiveness to pancreas cancer, stomach intestinal cancer and liver and gall. Jointly determine serum CA19 9 and CEA, can improve sensitiveness and specificity of screening gastric carcinoma.
3 CA50
CA50 is similar to CA19 9, can be used for monitoring progress stomach intestinal cancer and pancreas cancer of period, but the specificity is relatively CAl9 9 difference.
4 CA72 4
CA72 4 is one kind of mucinous molecules of the macromolecule quantity. Can be used for diagnosing and monitoring gastric carcinoma.
5 CAl95
CAl95 is a kind of glycoprotein or mucoprotein. Rise at intestinal cancer of stomach and the pancreas cancer patient's serum China CAl95 level, so can be regarded as the serum tumour sign of gastric carcinoma.
6 CA242
CA242 is a kind of mucoprotein. CA242 exists in normal pancreas, colon mucous membrane, but express low competence; Express in pancreas cancer, cancer of colon, rectal cancer and gastric carcinoma competently. CA242 assists diagnosing the sensitiveness of gastric carcinoma is similar to CEA and CAl9 9.
7 CYFRA2H
CYFRA2H one the intersection of cell and keratin, normal cell and malignant upper leather the intersection of support and albumen of cell. Take place as gastric carcinoma abdominal cavity shift and liver shift at the situation, serum CYFRA2H level rises. So, CYFRA2H is the reliable serum tumour mark that gastric carcinoma develops or recurs.
