Neurofibromatosis type 2 is characterized by bilateral vestibular schwannomas, which are benign tumors that originate from the nerve sheath and damage the nerve as they grow, causing neurological dysfunction such as hearing loss. Current standard radiation therapy can further augment hearing loss by inducing local damage to mature nerve tissue. Treatment with bevacizumab, a Vascular Endothelial Growth Factor (VEGF)-specific antibody, is associated with tumor control and hearing improvement in NF2 patients; however, its effect is not durable and its mechanism of action on improving nerve function is unknown. Anti-VEGF treatment can normalize the tumor vasculature, improving vessel perfusion and delivery of oxygen. It is known that oxygen is a potent radiosensitizer; therefore, combining anti-VEGF treatment with radiation therapy can achieve better tumor control and allow for the use of lower radiation doses, thus minimizing treatment-related neurological toxicity.Other Sources
