Antitumor activity of bevacizumab as a single agent in human gastric cancer xenograft models. (A) Mice bearing MKN-45 tumors were randomly divided into groups and HuIgG or bevacizumab (1.25, 5, 20 mg/kg) was administered intraperitoneally, once a week for 3 weeks. □: human IgG 20 mg/kg, : bevacizumab1.25 mg/kg, ■: bevacizumab 5 mg/kg, ▲: bevacizumab 20 mg/kg. (B) Differentiation degree of each tumor was determined by hematoxylin-eosin staining. (C) Antitumor activity of bevacizumab (5 mg/kg) was evaluated in various types of gastric cancer xenograft models: GXF97, MKN-28, NCI-N87, 4-1ST, SCH, SC-08-JCK, SC-09-JCK, SC-10-JCK. □: human IgG 20 mg/kg, ■: bevacizumab 5 mg/kg. (D) Antitumor activity of bevacizumab (5 mg/kg) was evaluated in two colorectal cancer xenograft models, COL-16-JCK and CXF280. □: human IgG 20 mg/kg, ■: bevacizumab 5 mg/kg. Data points are mean + SD of tumor volume (mm3). Statistically significant differences were shown as *: P < 0.05 vs. control group by Wilcoxon test. (n = 5-7/group).
