Trefoil factor family (TFF) proteins as potential serum biomarkers in patients with metastatic colorectal cancer.

Rok, strany: 2015, 470 - 477

Trefoil factor family (TFF) is composed of three secretory proteins (TFF1, TFF2 and TFF3) that play an important role in mucosal protection of gastrointestinal tract. Their overexpression in colorectal tumors seems to be associated with more aggressive disease. We collected serum samples from 79 healthy controls and 97 patients with metastatic colorectal cancer at the time of diagnosis or at progression. Serum levels of TTF1-3, CEA and CA19-9 were measured by ELISA. Serum TFF1 and TFF3 levels were significantly higher in patients with colorectal cancer compared to healthy controls (p < 0.0001). Moreover, serum levels of TFF3 correlated with extent of liver involvement in patient without pulmonary metastases and patients with higher TFF3 levels had significantly worse outcome (p < 0.0001). Compared to CEA and CA19-9, TFF3 had higher sensitivity and the same specificity. Our results indicate that TFF3 is an effective biomarker in patients with metastatic colorectal cancer with higher sensitivity than CEA a CA19-9. TFF3 levels strongly correlate with extension of liver disease and seem to have prognostic value. Keywords: colorectal cancer, TFF, TFF3, biomarker, survival
