Comparative Analysis of Ovarian Surface Epithelial Lesions with Corresponding Tubal Epithelial Changes with Reference to Ki67 and p53 Immunostains
Abstract: Ovarian surface epithelial cancers have high mortality due to late presentation. The ovarian surface epithelial tumours originate from fallopian tubal epithelium. Hence, ovarian surface epithelial tumours have good correlation with respect to genetic and immunohistological changes of fallopian tubes, especially fimbrial end epithelium. These changes are evident long before significant morphological changes in the ovaries appear. p53 and Ki67 are two important proliferative markers, and useful to evaluate ovarian surface …
