[Expression and clinical significance of epidermal growth factor receptor and protein kinase B in gastric carcinoma].
To evaluate the association between survival and expressions of epidermal growth factor receptor(EGFR) and protein kinase B(AKT) in gastric carcinoma specimens.EGFR and AKT were detected by immunohistochemistry in 84 patients with gastric cancer and 15 controls. Association between their expressions and clinical characteristics as well as prognosis were analyzed.In patients with gastric cancer,expression rates were significantly higher than those in 15 normal gastric tissues for EGFR(55.9% vs. 20%, P<0.05) and AKT(64.3% vs. 6.7%, P<0.01). Expression of EGFR was associated with late staging(P<0.01), while expression of AKT was associated with lymph node metastasis(P<0.01). Overall 5-year survival rate was significantly higher in patients with EGFR negative expression (49.0% vs. 22.0%, P<0.05). Overall 5-year survival rate was significantly higher in patients with AKT expression(45.7% vs. 30.2%, P<0.05).Expression of EGFR and AKT negative may be used to evaluate the degree of differentiation and prognosis in patients with gastric carcinoma.
