Purpose : Hepatocyte growth factor(HGF) is a modulator of epithelial cell proliferation
and motility. In this study, we measured the level of HGF in sera and tumor extracts of
gastric adenocarcinoma using an enzyme-linked immunoassay and evaluated its
association with tumor progression.
Materials and Methods : The level of HGF in the sera of seventy-five patients with
gastric adenocarcinoma and in the tumor extracts of forty-two tumors were examined in
this study. The level of HGF was determined by an Immunis HGF EIA kit(Institute of
Immunology).
Results : The mean level of HGF in the sera of patients was 0.26¡¾0.19ng/ml, which
was significantly higher than in those of healthy controls(0.14¡¾0.07ng/ml, p< 0.05); The
levels of HGF in the sera of patients increased according to the progression of the stage
of cancer(p<0.05). The mean level of HGF in tumor extracts was 8.22¡¾9.27§¶/g protein,
which was significantly higher than in those of healthy controls(1.95¡¾1.45§¶/g protein, p
<0.05); the levels of HGF in the tumor extracts were correlated significantly with the
progression of the tumor stage(p< 0.05). The mean level of HGF in the tumors of
diffuse type was 11.28¡¾11.74§¶/g Protein, which was significantly higher than in those
of intestinal type(5.16¡¾4.31 §¶/g Protein, p<0.05).
Conclusion : HGF may play an important role in the progression and differentiation of
gastric adenocarcinoma.
