SU6668 is an antiangiogenic agent that acts as a tyrosine kinase inhibitor for the vascular endothelial growth factor (VEGF) receptor. We treated xenografted A-431, a human squamous cell carcinoma cell line, with SU6668 to investigate the efficacy of tumor dormant therapy using angiogenesis inhibitors for patients with squamous cell carcinoma. A-431 cells were transplanted into severe combined immunodeficient (SCID) mice. The treatment group was given SU6668 at a dose of 200 mg/kg orally twice a day for 3 weeks; the control group was given only the vehicle in the same manner and intervals. SU6668 suppressed tumor growth of A-431 cells in the xenograft model. Furthermore, tumor volume and the number of vessels were significantly reduced in the treatment group compared with those of the control. No significant differences in body weight were found between the treatment and control groups, and no toxic reactions occurred during the experiment. We concluded that this agent was safe, efficient and potentially useful for the treatment of patients with squamous cell carcinoma.
