Serum hepatocyte growth factor level associate with gastric cancer progression

We have measured serum HGF levels from 80 gastric cancer patients and 51 normal subjects by enzyme-linked immunosorbent assay. The results showed that the mean value of serum HGF level in gastric cancer patients was significantly higher than in normal subjects (0.30 +/- 0.02 vs 0.22 +/- 0.05 ng/ml; p = 0.005). The increase was stage related. Patients with serum HGF < or = 0.30 ng/ml survived longer than those with serum HGF > 0.30 ng/ml (p = 0.02). These data suggest that HGF involve in progression of gastric cancer.
