Inhibiteurs de l'angiogenèse et radiothérapie : du concept à la clinique

Angiogenesis is central to cancer research. Recent progresses in understanding its mechanisms have enabled the development of therapies that inhibit this process. Many molecules have shown a synergistic effect in combination with irradiation in preclinical studies, and several are being tested in phase I or II. This effect could be explained by a transient normalization of tumor vasculature, leading to improve tumor oxygenation and thus greater radiosensitivity. Although promising, many questions remain about the dose, optimal sequences of the association.
