چکیده انگلیسی
SDF-1/CXCR4 axis is involved in various steps of breast tumorigenesis such as tumor growth, angiogenesis and metastasis. The goal of the present study is to demonstrate in detail the immunohistochemical distribution of SDF-1 and CXCR4 in invasive breast carcinomas and identify possible correlation of their expression patterns with clinicopathological parameters and patients survival. We investigated the immunoexpression of CXCR4 and SDF1 in 76 invasive breast carcinomas. Both SDF-1 and CXCR4 had statistically significant higher expression in carcinomas compared with adjacent normal breast tissue. Furthermore the expression of CXCR4 in intratumoral fibroblasts had a positive correlation with overall and disease-free survival, while SDF1 membranous immunopositivity in normal breast epithelial cells was a risk factor for relapse. In addition, expression of SDF1 in fibroblasts of normal breast tissue was positively associated with tumor grade. Overall, our results suggest that the differential expression of CXCR4 in intratumoral stroma and SDF1 in adjacent normal mammary cells may predict clinical outcome in breast cancer patients.
