The Value of TFF3 in Diagnosis of Gastric Cancer

Gastric cancer (GC), is a cancer developing from the inner lining of the stomach .The most common cause is infection by the bacterium Helicobacter pylori,which accounts for 60% of cases. Human pepsinogens (HP) are proenzymes for pepsin; digestive enzymes produced by gastric chief cells, classified into two groups: pepsinogen I (PGI) and pepsinogen II (PGII), humen pepsinogens considered promising serological biomarkers for the screening of atrophic gastritis and gastric cancer. The trefoil factor family (TFF) of peptides comprises small (12-22kDa) molecules that are secreted by the mammalian gastro-intestinal tract.Trefoil factor family 3 (TFF3) is a more stable non invasive biomarker of gastric cancer risk even in early gastric cancer.
