Rb pathway alteration and E2F-1 expression in epithelial ovarian cancer / 부인종양

ABSTRACT

OBJECTIVE: To evaluate the clinicopathological implications of Rb pathway alteration and E2F-1 expression in Epithelial ovarian cancer using immunohistochemical staining. METHODS: Tissue samples (n=72) were collected after staging operation between 1998 and 2004. RESULTS: In 72 cases, the overall expression of pRb, and E2F-1 were 59.7% (43/72), and 58.3% (42/72), respectively. pRb expression was inversely correlated with stage, histologic grade and mitotic index. E2F-1 expression was correlated with advanced stages, high grade, mitotic index, Ki-67 labeling index (LI). CONCLUSION: We suggest that Rb pathway alteration and E2F-1 expression could play roles as a new prognostic factors in Epithelial ovarian cancer.
