ABSTRACT
INTRODUCTION:
Syndecan-1 is heparan sulfate proteoglycans (HSPGs) that is used as coreceptors for signaling of growth factors. The comprehensive effect of syndecan-1 is to augment receptor stimulation at little ligand concentrations. THE GOAL OF THIS RESEARCH is to study syndecan-1 expression in breast carcinoma and its value in predicting the prognosis in comparison to other clinicopathological parameters. MATERIAL &METHODS:
immunohistochemistry study for syndecan-1 is done on 103 cases of invasive breast carcinoma. Its expression is assessed and correlated to other clinicopathological parameters and prognosis.RESULTS:
overexpression was significantly related to high histologic grade (p = 0.001), large tumor size (p = 0.043), HER2-positive status (p = 0.001), and ER&PR-negative status (p = 0.001). It was also have a negative impact on the overall survival (p=0.012) and disease free survival (p = 0.009). Syndecan-1 expression showed weak positive correlation with Her 2 expression (Correlation Coefficient (co) 0.332, p = 0.001).CONCLUSION:
syndecan-1 is a good predictor of poor overall survival and recurrence/ metastasis free survival. It is associated with aggressive phenotype as HER2 enriched and Triple negative rather than luminal subtypes of breast carcinoma. So it can be added to the hormonal receptors and HER 2 assay in the routine management of invasive breast cancer after confirmation on a more larger study.Palavras-chave
