METHODS: Immunohistochemical avidin-biotin peroxidase complex method was applied to detect the expression of ATP7B in 49 cases of cardiac carcinomas, the corresponding adjacent non-neoplastic epithelium and 55 cases of distal gastric carcinomas. RESULTS: The proportion of ATP7B positive samples in gastric cardiac carcinomas (51.0%, 25 of 49) was significantly higher than that in the corresponding adjacent non-neoplastic epithelium (22.4%, 11 of 49) (P = 0.003). ATP7B expression in poorly differentiated gastric cardiac carcinomas was significantly higher than that in well/moderately differentiated gastric cardiac carcinomas (P = 0.030). ATP7B expression in gastric cardiac carcinomas was independent of age, tumor size, nodal stage and metastasis status. ATP7B protein was detected in 30.9% (17/55 cases) of distal gastric carcinomas, markedly lower than that in gastric cardiac carcinomas (P = 0.037). CONCLUSION: ATP7B protein is frequently overexpressecl in gastric cardiac carcinomas, and correlated with the differentiation of cardiac carcinoma. ATP7B expression in gastric cardiac carcinomas is significantly higher than that in distal gastric carcinomas, which might partially explain the difference of chemotherapy response and prognosis between these two gastric carcinomas.展开更多

Results Among healthy controls, frequencies of the TNF-α 1/1, 1/2 and 2/2 genotypes were 89.4% ,9.2% and 1.4% respectively, while frequencies of the TNF-β B1/B1, B1/B2 and B2/B2 genotypes were 12.6% , 32.3% and 55.1%, respectively. No significant difference was found in the overall genotype and allelotype distribution of the TNF-α-308G/A and TNF-β + 252G/A SNPs among cancer patients and controls. However, both the B1/B1 genotype and B1/B2 genotype significantly increased the risk of developing ESCC [ the age and gender adjusted odds ratio (OR) =2.04 and 1.91, 95% confidence interval (CI) = 1.04 -4.43 and 1.14 - 2.60, respectively] and GCA (the age and gender adjusted OR =2. 68 and 2. 64, 95% CI = 1.14 -6.29 and 1.47 -4.72, respectively) in individuals with negative family history of UGIC, in comparison with the B2/B2 genotype. When the two TNF polymorphisms were combined and analyzed, individuals with the TNF-β B1/B2 and TNF-α1/2 or 2/2 genotypes significantly reduced the risk of developing ESCC and GCA, in comparison with those harboring the TNF-β B2/B2 and TNF-α 1/1 genotypes ( the age and gender adjusted OR = 0.37 and 0. 34, 95% CI =0. 15 -0.92 and 0. 13 -0.90, respectively). Conclusions Therefore, the TNF-α -308G/A and TNF-β + 252G/A genotyping may be used as a stratification markers to predicate the risk of ESCC and GCA development in North China.展开更多
