Since angiogenesis is critical for tumor growth and metastasis, anti-angiogenic treatment is a highly promising therapeutic approach. Thus, for over last couple of decades, there has been a robust activity aimed towards the discovery of angiogenesis inhibitors.

This review discusses agents that have been approved by FDA and are currently in use for treating patients either as single-agents or in combination with other chemotherapeutic agents. © Samant et al.
