Abstract:
Background:Gastric cancer is the second most frequently diagnosed cancer and the third cause of cancer death in China. Selection of candidates in high risk of gastric cancer by a simple and non-invasive marker with high sensitivity and then undergoing endoscopy is an optimal approach for large scale gastric cancer screening. Aims:To evaluate the clinical value of using trefoil factor 3(TFF3)as a serum biomarker for gastric cancer screening. Methods:Serum samples of 49 gastric cancer patients and 29 healthy subjects were collected for measurements of serum TFFs by ELISA from Jul. 2013 to Jan. 2014 at Ningbo Medical Treatment Center Lihuili Hospital. ROC curve and the area under curve(AUC)were used to verify the diagnostic performance of serum TFF1,TFF2 and TFF3 for gastric cancer. Correlations between TFFs and clinicopathological characteristics of gastric cancer were further analyzed. Results:Serum concentration of TFF3 in gastric cancer group was significantly higher than that in healthy controls[(43. 57 ± 19. 49)ng/ mL vs.(29. 97 ± 14. 20)ng/ mL, P < 0. 01],but no significant differences were found in serum concentrations of TFF1 and TFF2 between the two groups (P > 0. 05). AUC of serum TFF1,TFF2 and TFF3 for diagnosis of gastric cancer were 0. 56,0. 56 and 0. 83, respectively,which indicated that the performance of TFF3 was the best. Taken 33. 0 ng/ mL as the cut off value of TFF3, the sensitivity and specificity were 63. 3% and 82. 8% ,respectively,and the odds ratio for predicting gastric cancer was 8. 27. Significant correlations were existed between serum concentration of TFF3 and TNM stage,differentiation and lymph node metastasis of gastric cancer(P < 0. 05). Conclusions:Serum TFF3 is a promising non-invasive biomarker for gastric cancer screening.
