Method for assay on the effect of vascularization inhibitor

摘要

The present invention provides a method of predicting the antitumor effect of an angiogenesis inhibitor. It is possible to predict the antitumor effect of an angiogenesis inhibitor by evaluating the EOF dependency of a tumor cell for proliferation and/or survival and using the EGF dependency as an indicator. Since the antitumor effect of an angiogenesis inhibitor correlates with the EGF dependency of a tumor cell for proliferation and/or survival, the angiogenesis inhibitors is capable of producing excellent antitumor effect when combined with a substance having EGF inhibitory activity.
