Figure 4From: Huachansu injection inhibits metastasis of pancreatic cancer in mice model of human tumor xenograft ELISA analysis for the concentration of CEA and CA19-9 in serum after HCS treatment. (A) The CA19-9 concentrations in serum in HCS-treated groups differed significantly from that of the Control (P = 0.038); (B) The CEA concentrations were not different statistically among the Control and HCS groups (P>0.05), Data analyzed by Kruskal-Wallis test. (C) The linear regression analysis indicated that after HCS treatment, CA19-9 in serum decreased with the number of liver metastases reduced (R2 = 0.442, P = 0.0026), but which was independent of CEA in serum (R2 = 0.001, P = 0.8899).Back to article page
