Abstract

Objective: The objective of this study was to examine the occurrence of ovarian endometriosis in epithelial ovarian cancer in Japan. Method: The presence of ovarian endometriosis was determined by reviewing the sections of resected specimens in 172 epithelial ovarian cancers. Results: The incidence of ovarian endometriosis in ovarian cancer (14.5%) was higher than that in Western countries. The rank order of incidence of endometriosis in each histologic type was clear cell (40.6%)>endometrioid (23.1%)>serous (8.7%)>mucinous (2.9%). The incidence in serous type was higher when compared with that reported in Western countries. The higher incidence of endometriosis in Japan can be explained by a greater proportion of clear cell type, comprising 18.6% of all the cases and a higher incidence of endometriosis in the serous type. Conclusion: The association of ovarian endometriosis with epithelial ovarian cancer was more frequently found in Japan.
