title: Using anti-VEGF McAb and magnetic nanoparticles as double-targeting vector for the radioimmunotherapy of liver cancer.
abstract: To study the biodistribution of a new radioimmunoconjugate-131I-anti-VEGF monoclonal antibody (Sc-7269)-Dextran Magnetic Nanoparticles (DMN) in nude mice bearing human liver cancer where an external magnetic field was focused on, and to evaluate its therapeutic effects and safety. Tumor Growth Delay (TGD) and tumor inhibition rate were observed as antitumor effect. Peripheral white blood cells counts and the loss of body weight were tested as an indicator of systemic toxicity. The results suggests that the radioimmunotherapy of intratumoral injection of 131I-Sc-7269-DMN may be safe and efficient for the treatment of liver cancer. Furthermore, the radioimmunotherapy using DMN as a 'carrier system' may be a highly potential approach in the treatment of other kind of tumors.
