Introduction: Breast cancer is the most frequent solid malignancy in women. Omentin-1 is synthesized by visceral adipose tissue, placenta, and ovary and its production is altered in some cancers. The aim of this study was to assess omentin-1 as a diagnostic marker in patients with breast cancer.

Methods: The participants of the study included 90 women (45 patients with breast cancer and 45 healthy women as control group). In addition to anthropometric and blood parameters analysis, omentin-1 serum levels were measured by enzyme-linked immunosorbent assays method. Receiver operator characteristic curve and positive and negative predictive values (PPV and NPV) were calculated to define diagnostic accuracy.

Results: Serum omentin-1 level in breast cancer patients (157 ng/L ± 66 ng/L, mean ± SD) was significantly lower than that of the control group (217 ng/L±75 ng/L, mean ± SD). There was no significant correlation between omentin-1 levels and anthropometric and blood parameters. The best cut-off point for the diagnosis of breast cancer was at 146 ng/L. The sensitivity and specificity for omentin-1 with 95% CI (0.611 to 0.837) were 60% and 85%, respectively. Calculated PPV and NPV at the 146 ng/L cut-off point were 88.8% and 51.5%, respectively.

Conclusion: Breast cancer patients had significantly lower serum level of omentin-1 than healthy women. Omentin-1 may be beneficial as a screening test along with the early-approved methods in the diagnosis of patients with breast cancer.
