摘要
目的:探讨原癌基因c-erbK-2基因蛋白和表皮生长因子受体在泌尿系移行细胞癌发生发展中作用。方法;应用免疫组织化学方法研究c-erbB-2和表皮生长因子受体(EGFR)在65例泌尿系移行细胞癌(包括47例膀胱癌和18例肾盂癌)的表达。结果:c-erbH-2蛋白在膀胱癌和肾盂癌的表达率分别为40.4%和38.9%;EGFR的表达率分别为膀胱癌46.8%。肾盂癌44.4%;c-erbB-2和EGFR表达均与膀胱癌和肾盂癌的分级和分期有关,c-erbW-2和EGFR有显著相关关系。结论:c-erbB-2和EGFR表达反应了癌细胞增殖状态,可作为膀胱癌和肾盂癌生物学行为和预后评估的一项重要指标。
Purpose: To investigate the role of oncogene c-erbB-2 and epidermal growth factor receptor (EGFR) in carcinogenesis of transitional cell carcinoma of urinary system. Method: Expression of c-erbB2 and EGFR were studied in 65 transitional cell carcinoma (include 47 bladder carcinoma and 18 renal pelvis carcinoma) with immunohistochemical technique. Results: Positive rates of cerbB-2 were 40. 4% and 38. 9% and of EGFR were 46. 8% and 44. 4 % in bladder carcinoma and renal pelvis carcinoma respectively.Significant relationship was observed between c-erbB-2,EGFR and the grade or stage of the tumor. Conclusion: c-erbB-2 and EGFR involved in cell proliferation state and might be served as markers for the eva1uation of biological behavior and prognosis in bladder carcnoma and renal pelvis carcinoma.
