Background: Syndecan-1 binds to various extracellular matrix components via its heparan sulfate glycosaminoglycans. The aim of this study was to investigate syndecan-1 expression in endometrial cancers. Patients and methods: We investigated the expression of the syndecan-1 core protein by immunohistochemistry in 109 endometrial cancers, and analyzed correlation with various clinicopathological features, including patient outcome. Results: Epithelial syndecan-1 expression was significantly lower in advanced stage, high grade, deep myometrial invasion, cervical involvement, lymph node metastasis, lymph vascular space involvement and positive peritoneal cytology. Stromal syndecan-1 expression was significantly higher in high-grade tumors. The disease-free and overall survival rates of patients exhibiting both low epithelial and high stromal syndecan-1 expression was poor. Multivariate analysis showed that high stromal syndecan-1 expression was an independent prognostic factor for both disease-free and overall survival. Low epithelial syndecan-1 expression was a prognostic factor only in the univariate analysis. Conclusions: Loss of epithelial syndecan-1 and induction of stromal syndecan-1 expression may be associated with tumor progression. Stromal syndecan-1 expression can serve as an indicator of poor prognosis in patients with endometrial cancer.
