자궁경부의 전암성 병변과 침윤성 편평상피암종에서 p63과 p53 단백 발현

초록

Objective : p63 is a member of the p53 gene family. The main aim of this study was to compare p63 and p53 expression in precancerous lesions and invasive squamous cell carcinoma of the uterine cervix. Methods : Total 81 formalin-fixed, paraffin-embedded sections of low-grade squamous intraepithelial lesion (22 cases), high-grade squamous intraepithelial lesion (42 cases) and invasive squamous cell carcinomas (17 cases) in the uterine cervix were stained by immunohistochemistry for expression of p63, p53 and topoisomerase II- . Results : p63 was statistically significant higher immunoreactivity according to progression of uterine cervical squamous lesions, but p53 was not significant. No statistical correlation was found between p63 and p53. Topoisomerase II- index was statistically significant higher according to increase of p63 expression. Conclusion : These findings suggest that the expression of p63 protein may play a roles in progression and proliferative activities of the uterine cervical squamous lesions.
