	abstract = {OBJECTIVE: Previous studies have shown that visfatin is significantly elevated in patients with gastric carcinoma and postmenopausal breast cancer (PBC). We thus explored whether serum visfatin could be used as a potential diagnostic and prognostic tool for PBC, taking into account clinicopathological features, serum tumor markers, anthropometric and metabolic parameters.

METHODS: Serum visfatin, tumor marker CA 15-3, carcinoembryonic antigen, metabolic and anthropometric parameters were determined in 103 postmenopausal women with pathologically confirmed, incident invasive breast cancer, 103 controls matched on age and time of diagnosis, and 51 patients with benign breast lesions (BBL).

RESULTS: Mean serum visfatin was significantly higher in cases than in controls and patients with BBL (p<0.001). In cases, visfatin was significantly associated with CA 15-3 (p=0.03), hormone-receptor status (p<0.001), lymph node invasion (p=0.06) but not with metabolic and anthropometric variables (p>0.05). Multivariable regression analysis revealed that absence of estrogen and progesterone receptors (ER-PR-) was the strongest significant determinant of serum visfatin (p<0.001) in cases adjusting for demographic, metabolic and clinicopathological features. Based upon receiver operator characteristic analysis, serum visfatin outperformed CA 15-3 only in discriminating between PBC cases with early cancer stage than those with late stage, and in differentiating particularly patients with ER-PR- breast tumors.

CONCLUSION: Further prospective and longitudinal studies are needed to determine whether serum visfatin could be used as a prognostic tool in the armamentarium of PBC monitoring and management in conjunction with other biomarkers.},
