Prognostic and clinicopathological value of CXCL12/SDF1 expression in breast cancer: A meta-analysis

This present meta-analysis suggests that CXCL12/SDF1 protein expression is a good prognostic biomarker in breast cancer. In addition, the over-expression of CXCL12/SDF1 protein was associated with positive ER status, negative HER2 status and small tumor size.
