Annexin A10 Expression Is Associated With Poor Prognosis in Small Bowel Adenocarcinoma

Background/aim Small bowel adenocarcinoma (SBA) is a relatively rare malignant epithelial neoplasm. Thus, little is known about prognostic biomarkers of SBA. Annexin A10 (ANXA10) is a member of the annexin family. The significance of ANXA10 expression in SBA is unclear. This is the first study to examine the expression of ANXA10 in SBA. Materials and methods We immunohistochemically evaluated ANXA10 expression of SBA and studied the relationship between ANXA10 expression and clinicopathological factors. Results ANXA10 expression was detected in 17 (56.7%) of 30 SBA cases and was significantly associated with poor overall survival. Univariate predictors for poor prognosis were tumour size (p=0.017) and ANXA10 expression (p=0.026). In multivariate analysis, ANXA10 expression (p=0.038) and tumour size (p=0.024) were found to be independent predictors of poor prognosis. Conclusion ANXA10 could be a new prognostic biomarker for SBA.
