The transcription factor Sox11 is a prognostic factor for improved recurrence-free survival in epithelial ovarian cancer

• Abstract Background: Current prognostic molecular markers for epithelial ovarian cancer (EOC) are insufficient. The aim of the current study was to investigate the role of Sox11 in EOC Methods: Using an in silico transcriptomic screen Sox11 was identified as a potential EOC biomarker. Sox11 protein expression was evaluated using immunohistochemistry (IHC) in 76 EOC cases, which were analyzed using automated algorithms to develop a quantitative scoring model. Results: Sox11 mRNA expression was up-regulated in EOC compared to normal tissues. Automated analysis of Sox11 in the EOC cohort revealed high expression of Sox11, in 40% of tumours, who had an improved recurrence free survival (RFS) (p= 0.002). Multivariate analysis confirmed Sox11 was an independent predictor of improved RFS after controlling for stage and grade. Conclusions: These data suggest that Sox11 is a new prognostic marker in EOC. Loss of SOX 11 is associated with a decreased RFS and a more aggressive phenotype.
