Abstract
AIM: To investigate the correlation between Her-2 protein expression and clinicopathological characteristics of gastric carcinoma.
METHODS: Her-2 protein expression was examined by immunohistochemistry (EliVisionTM plus) in 778 gastric adenocarcinoma specimens.
RESULTS: The positive rate of Her-2 protein overexpression (+++) was 11.35% (68/576). Her-2 protein overexpression was associated with tumor histotype, differentiation, TNM stage, and distant metastasis (all P < 0.05), but not with sex, age, tumor site, and lymph node metastasis (all P > 0.05). Multivariate analysis demonstrated that tumor histotype, differentiation, TNM stage, and distant metastasis were significant predictors of Her-2 protein overexpression in gastric carcinoma (all P > 0.05). Moderate Her-2 protein expression (++) was detected in 5.68% of gastric carcinoma specimens.
CONCLUSION: Detection of Her-2 protein expression may be used to assess the malignant biological behavior and prognosis of gastric cancer. Gastric cancer patients exhibiting Her-2 protein overexpression might constitute potential candidates for new adjuvant therapies that involve the use of humanized monoclonal antibodies.
