Temozolomide for treatment-resistant recurrent meningioma.

A prospective Phase II study of temozolomide (TMZ) was conducted in 16 patients with refractory meningioma. All patients had previously been treated with surgery and involved-field radiotherapy; however, no patient had prior chemotherapy. TMZ was administered orally for 42 consecutive days every 10 weeks. Grade 3 or greater TMZ-related toxicity included anemia (25%), fatigue (18.7%), neutropenia (37.5%), seizures (6.3%), and thrombocytopenia (18.7%). No patient demonstrated a neuroradiographic complete or partial response. Time to tumor progression ranged from 2.5 to 5.0 months (median 5.0 months); survival ranged from 4 to 9 months (median 7.5 months).
