Introduction: Galectin-1 is over-expressed in human breast cancer cells, compared to none or limited expression in benign hyperplasia or normal cells. It is secreted in the extracellular space of cancer cells and tumour-associated endothelial cells. Aim: We aim to investigate the diagnostic and prognostic value of serum Gal-1 in breast cancer patients. Subjects & Methods: 100 newly diagnosed patients with different stages of breast cancer, who were not subjected to chemotherapy or radiotherapy and 100 healthy females as control were included. Serum Gal-1and CA15-3 was assayed by ELISA, and micro particle enzyme immunoassay respectively. The association of galectin-1 with CA15-3 and clinic pathological variables was evaluated. Results: Gal-1 and CA15-3 levels were significantly higher in patients than controls. Gal-1 was significantly increased in breast cancer patients who have advanced TNM stage and positively correlated with tumour size and grade. Significant positive correlations between Gal-1 and CA15-3 levels in breast cancer patients were found. The combination of the two markers resulted in improved sensitivity (85.2 % instead of 83.3 %) and specificity (61 % to 64 %) than using Gal-1 alone and improvement of CA15-3 sensitivity from 33 % to 85.2 %. Conclusion: Our results suggest that Gal-1 can be used as a screening and prognosis biomarker for breast cancer.
