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.
