Higher grade tumors have been shown to correspond with higher recurrences. Depending on the grade and extent of resection, from less than 1 in 10 to over two-thirds of tumors will recur after surgical excision. Follow-up clinical exams, as well as neuroimaging, can aid in detecting recurrences. As many<unk> s have receptors for progesterone, progesterone blockers are being investigated. Two other drugs that are being studied for use are hydroxyurea and interferon alpha-2b.
