ABSTRACT
Objective To investigate the expression of Smad4 in gastric carcinoma and its relationship with clinicopathological characteristics. Methods Immunohistochemistry method was used to detect the expression of Smad4 in 85 gastric carcinoma tissue and 36 normal gastric mucosa from January 2014 to December 2016. Results (1)The positive expression rate of Smad4 in gastric carcinoma tissues was 35. 29% (30/ 85), which was significantly lower than that in normal gastric mucosa (91. 67% (33/ 36)),and the difference was statistically significant (χ2=32. 201,P<0. 001). (2) The expression of Smad4 was correlated with the depth ofinvasion(χ2=13. 626,P<0. 001),lymph nodes metastasis(χ2=7. 267,P=0. 007),TNM staging(χ2=18. 226,P<0. 001) and tumor differentiation level (χ2 = 9. 134, P= 0. 010) . ( 3) Multivariate unconditional logistic regression analysis showed that depth of invasion(OR=7. 892,95CI 1. 649-37. 790,P=0. 010),TNM staging ( OR=15. 042, 95CI 0. 026-0. 977, P=0. 005 ) and tumor differentiation level ( OR=15. 042, 95CI2. 292-98. 751, P = 0. 005 ) may be independent influencing factors for Smad4 expression in gastric carcinoma. Conclusion Smad4 may performed an important role during the progression of gastric carcinoma and may be a new biological marker of gastric carcinoma.
