We examined the expression of the steroid and xenobiotic receptor (SXR) and evaluated its clinical significance in human epithelial ovarian carcinoma. One hundred forty-one cases were examined using immunohistochemistry for SXR with archival specimens. All cases were scored using a semi-quantitative histological scoring (HSCORE) method. Specimens with an HSCORE > 60 were regarded as SXR-positive. Various clinicopathologic variables were examined. SXR showed significant differences in age, histology, grade, ERα and PR. SXR was detected in 35 of 141 (24.8%) ovarian cancer tissues. There was a statistically significant negative correlation between SXR-positive status and both disease-free survival and overall survival (P = 0.0415 and 0.0316, respectively), independent of stage (P = 0.0167 and 0.021, respectively). In multivariate analysis, SXR was a statistically independent risk factor for both disease-free survival and overall survival (P = 0.049 and 0.0354). Our results support an association of SXR between ERα and PR in epithelial ovarian cancers. Our data suggest that SXR is a prognostic factor in epithelial ovarian cancer and may represent a useful marker to identify patients at risk of recurrence or death.
