Abstract

Prophylactically removed ovaries from 64 women were compared with those from 30 women with no known family history of ovarian cancer for expression of the p53 tumor suppressor protein, the c-erbB-2 oncoprotein, and for the proliferation antigen Ki-67. All analyses were performed without knowledge of the family history. Ki-67 was expressed in rare nuclei in both the surface and cyst epithelial cells, whereas p53 was expressed in rare nuclei only in cyst epithelial cells. Neither the proportion of positive cases nor the intensity of staining differed between groups, c-erbB2 was not expressed in surface or cyst epithelium in any case from either group. Nuclei of granulosa and granulosa lutein cells expressed both Ki-67 and p53. In conclusion, increased expression of p53, c-erbB2, and Ki-67 was not found in the epithelium of prophylactically removed ovaries, suggesting that increased expression occurs later in the development of carcinoma or invasive tumor evolves too quickly to identify expression of these proteins in preinvasive epithelium.
