This study was conducted to investigate the serum levels of membrane-bound mucin 2 (MUC2) in breast cancer (BC) patients and the relationship with tumour progression and known prognostic parameters. We enrolled 127 female patients with histopathologically diagnosed BC who did not receive chemotherapy (CT) or radiotherapy. Serum MUC2 levels were measured by the enzyme-linked immunosorbent assay (ELISA) method and compared with those of 40 age and sex-matched healthy controls. Median age of diagnosis was 50 (range: 26-78). Twenty-eight (22%) patients were metastatic and the most frequent site of metastasis was bone (n = 17, 61%). The median serum MUC2 level of BC patients was significantly higher than that of the controls (198 vs. 54 ng/mL, p < 0.001). There was no significant difference between patients and controls according to known disease-related clinicopathological or laboratory parameters (p > 0.05). Serum MUC2 levels were not associated with survival (p = 0.65). Although serum MUC2 levels might have a diagnostic role, their predictive and prognostic role in survival in BC patients was not detected. Serum levels of MUC2 should be investigated for diagnostic or screening purposes on a larger scale.
