Statistical analyses of CXCL12high and CXCL12low/moderate immunostaining and classical clinical parameters, such as histotype, HER2 status, FIGO stage, ascites and size of residual tumor after first laparotomy, revealed no significant correlation of CXCL12 status with any of the parameters tested (Table 1). This evidence concerns the gene CXCL12 and neoplasm.
