| Research Abstract |
The anti-tumor effect of the angiogenesis inhibitors increased in the following order; bevacizumab, sorafenib, and thalidomide. The anti-tumor effects of the dual therapies except sorafenib and thalidomide were lower than those of the single therapies. However, the numbers of the dual therapies were not enough to consider them, therefore, more studies about the dual therapies were necessary. When the anti-tumor effect of the angiogenesis inhibitor was determined, the best and simple way was to measure the change of the tumor sizes before and after the therapy using CT. To measure the change of enhancement ratio using CT / DSA and to evaluate the necrosis ratio and the numbers of tumor vessels pathologically were unfitted for the response evaluation of the angiogenesis inhibitors.
