摘要

The unique features of tumor vasculature represent an attractive target that can be utilized by vascular targeting therapy (VTT). The Pharmaceuticals applied in VTT are classified into angiogenesis inhibiting agents (AIAs) and vascular disrupting agents (VDAs) according to their mechanisms of action. AIAs inhibit the formation of new vessels, while VDAs selectively destroy the existing tumor vessels. Both reduce the blood supply, cause the tumor necrosis, and delay the tumor growth, but they cannot eradiate tumor. This novel VTT challenges the traditional criteria for therapeutic evaluation based on tumor size. Functional and metabolic studies are thus necessary to monitor the early vascular alterations and to estimate the therapeutic efficacy for prompt justification and adjustment in oncological patients under the VTT regimen, In this article, we review the characteristics of tumor vessels, classification of VTT, and lead drugs in clinical development. We also envision, in addition to the conventional anatomy-based criteria, comprehensive imaging protocols for the assessment of tumor response to VTT combining morphological, functional and metabolic imaging biomarkers, applicable for magnetic resonance imaging, computed tomography, positron emission tomography, and ultrasound.
