Temozolomide is a novel oral alkylating agent, which has been reported to be effective in treating patients with recurrent malignant gliomas. This study report an analysis of the activity and toxicity of temozolomide as second-line therapy for patients with recurrent and progressive malignant gliomas after surgery and standard radiation therapy with or without chemotherapy. METHODS: Twenty patients with malignant gliomas of which thirteen(65%) had glioblastoma multiforme(GBM), five(25%) with anaplastic astrocytoma(AA), and two(10%) with anaplastic oligodendroglioma(AO) were enrolled in this study. They had been treated in our institution since July, 2000 and had been previously irradiated with or without chemotherapy. For the patients with recurrent and progressive disease, temozolomide(150-200mg/m2/d x5 days) was administered every 28 days until the progression of the tumor or toxicity developed. RESULTS: The median number of treatment cycles was 3(total 86). Of the 20 patients, 2(10%) achieved a complete response(CR), 5(25%) achieved a partial response(PR), 5(25%) had stable disease(SD), and 8(40%) had progressive disease(PD). One patient achieved a CR, 3 patients achieved a PR, 2 patients had SD and 7 patients had PD in GBM, and 1 patient achieved a CR, 2 patients achieved a PR, 3 patients had SD, 1 patient had PD in the non-GBM patients. Median progression free survival(PFS) was 8 weeks in GBM and 22 weeks in the non-GBM patients. No hematological toxicity greater than grade 2 was observed, and hepatotoxicity of grade 2 was encountered in 1(5%) patient. CONCLUSION: Temozolomide demonstrate moderate activity in recurrent and progressive malignant brain tumors, and the response rate and PFS were better in the non-GBM tumors than in the GBM tumors. The treatment is well tolerated without any serious toxicity.
