| Abstract |
OBJECTIVE
The relationship was studied between expression of c-erbB-2 oncoprotein and topoisomerase II-alpha as proliferating marker in precancerous lesions and invasive squamous carcinomas of the uterine cervix. METHODS: Total 81 formalin-fixed, paraffin-embedded sections of low-grade intrasquamous lesion (22 cases), high-grade intraepithelial lesions (42 cases) and invasive squamous cell carcinomas (17 cases) in the uterine cervix were stained by immunohistochemistry for expression of the c-erbB-2 oncoprotein and topoisomerase II-alpha. RESULTS: The expression of c-erbB-2 oncoprotein and staining index (mean+/-S.D) of topoisomerase II-alpha were statistically significant between precancerous lesions and invasive carcinoma. The expression of c-erbB-2 oncoprotein has correlation with staining index (mean+/-S.D) of topoisomerase II-alpha. CONCLUSION: There results suggest that the expression of c-erbB-2 protein has relationship with progression of squamous lesions and topoisomerase II-alpha is an useful proliferating marker in the uterine cervix. And, the expression of c-erbB-2 protein has correlation with expression of topoisomerase II-alpha. |
