This type of tumor, also called acoustic neuroma, causes hearing loss and can press on the brain stem, leading to serious neurologic symptoms and the risk of death. Currently, these tumors are treated with surgery or radiation. This study found that treatment with the angiogenesis inhibitor bevacizumab (Avastin) shrank vestibular schwannomas, improved hearing and eased other symptoms in NF2 patients. Bevacizumab is an anti-cancer drug designed to reduce blood flow to tumors in order to shrink them. But the drug wasn't used on acoustic neuromas because it was believed that ... Read more
