ABSTRACT
Objective:The study aims to investigate the expression of integrin ?V?3 and its relationship in gastric cancers.Methods:The tumoral and normal tissues were collected from 65 cases of gastric cancer patients and 40 controls.The clinical phasing and pathological staging of the patients were recorded,and immunohistochemical analysis was used to detect the expression of integrin ?V?3 and microvessel density(MVD)in gastric cancers.Results:The positive rate of integrin ?V?3 expression was significantly higher in gastric cancer tissues than normal mucosal tissues(72.38% vs 22.86%,?2=8.35,P=0.032).There was a significant difference in integrin ?V?3 expression or MVD between tumors of infiltrating and expanding growth patterns(?2=14.97,P=0.002;t=10.150,P=0.001,respectively),cancers in T3～T4 and T1～T2 stages(?2=15.21,P=0.015;t=5.961,P=0.001,respectively).The positive rate of integrin ?V?3 expression and MVD also showed corelationship with lymph node invasion and metastases.Conclusion:Tumoral expression of integrin?V?3 was closely related with biological behavior of gastric cancers,suggesting that detection of integrin ?V?3 expression may present a potential tool to evaluate the clinical and pathological staging,lymph node status and metastases.
