Fig. 3From: CXCR4 and its ligand CXCL12 display opposite expression profiles in feline mammary metastatic disease, with the exception of HER2-overexpressing tumorsCXCL12 status has prognostic value in cats with HER2-overexpressing mammary carcinoma. a Kaplan-Meier analysis showing the overall survival (OS) of cats with HER2-overexpressing mammary carcinoma, presenting CXCL12 positive and negative expression in primary tumors (PT). b Kaplan-Meier curve illustrating the disease-free survival (DFS) of cats with HER2-overexpressing mammary carcinoma, stratified according to CXCL12 expression in PT. Comparison between the two groups was performed by the log-rank (Mantel Cox) testBack to article page
