Background: Steocalcin (OCN) is a bone tissue-specific protein overexpressed in several human cancers. However, the physiological roles of OCN in endometrial cancer (EC) are unclear. This study aimed to investigate its prognostic impact on OCN expression in EC patients and their associations with clinicopathologic features. Methods: Between July 2010 and December 2013 at the Department of Obstetrics and Gynecology, Shanghai Pudong Hospital, we performed immunohistochemistry to detect OCN expression in 134 EC patients and 35 normal endometria (non-EC) specimens and analyze its correlation with clinicopathologic features. The enzyme-linked immunosorbent assay (ELISA) analyzed the OCN expression in serum. OCN expression was also detected in fresh tissues using real-time polymerase chain reaction (PCR) and western blotting. Results: OCN mRNA and protein expressions were significantly lower in EC tissues than adjacent normal tissues (p < 0.001). Low OCN expression was significantly associated with the International Federation of Gynecology and Obstetrics (FIGO) stage, lymph node metastasis, and depth of myometrial invasion (p < 0.01). Kaplan-Meier analysis exposed a significant difference in overall survival (OS) and disease-free survival (DFS) between EC patients with low and high OCN expression levels (log-rank, both p < 0.001). Moreover, multivariate Cox regression analysis showed that OCN expression was an independent predictive factor for overall survival (OS) (p = 0.043) and disease-free survival (DFS) (p = 0.027) in EC patients. Spearman’s rank correlation analysis stated a positive correlation between serum OCN level and adiponectin (r = 0.455, p < 0.001) and a negative correlation between serum OCN level and leptin (r = −0.307, p < 0.001). Conclusions: The results speculate that the low OCN expression is associated with the progression and recurrence of endometrial cancer.
