Abstract:

Angiogenesis refers to the process of forming a new network of blood vessels from existing ones through the migration, proliferation, and differentiation of endothelial cells. This process is crucial for the growth and spread of solid tumors, particularly once the tumor volume exceeds 2 mm3, as the newly formed vascular network provides essential oxygen, nutrients, and growth factors to the tumor. Anti-angiogenesis therapy has become one of the commonly used targeted treatments for cancer in clinical practice. Bevacizumab, the first anti-angiogenesis drug, has been widely applied in the treatment of various solid tumors. However, due to acquired resistance, its efficacy is typically sustained for only 1 to 2 years. Despite the relative genomic stability of endothelial cells, which makes resistance less likely, various types of resistance phenomena have been observed in clinical practice, indicating that resistance to anti-angiogenic therapy remains a challenging research area. This review focuses on the latest advances in the mechanisms of resistance to anti-angiogenic therapy in tumors and explores new prospects for anti-tumor angiogenesis treatment, in order to provide strong theoretical support and guidance for clinical practice.
