Abstract
Objective To investigate the relationship between the expression of decay receptor 3 (DcR3) and the eliniealpathological parameters in human gastric carcinoma. Methods The expression of DcR3 was examined by RT-PCR in a series of 41 human primary gastric carcinomas and 41cases of normal tissue adjacent to tumor. Multiple clinical pathological factors were analyzed according to their relation with the expression of DcR3. Results The positive rate of expression of DcR3 was 56 %(23/41) in human gastric carcinoma. The expression of DcR3 in gastric carcinoma was significantly higher than that in normal tissues adjacent tumor. The expression of DcR3 was significantly correlated with different degrees of differentiation, lymph node metastasis and TNM staging (P 0.10). The multiple linear regression equation was Y=0.432-0.208X1+0.098X2+0,086X3. Conclusion DcR3 expression can be highly found in gastric carcinoma. The abnormal expression of DcR3 may promote tumorigenesis and progression. DcR3 may be important in evaluating the tumor differentiation, infiltration depth, lymph node metastasis and TNM staging of human gastric carcinoma.
