Temozolomide (TMZ) has demonstrated activity and acceptable toxicity for the treatment of recurrent malignant gliomas in carious prospective phase II studies. No information is, however, available on TMZ treatment for recurrent malignant glioma in Japanese patients. We report Hokkaido University Hospital experience on 35 adult patients with a recurrent malignant glioma, including 13 glioblastomas, 9 anaplastic astrocytomas, and 13 anaplastic oligondendroglial tumors. ⋯ Although hematological toxicity was the most frequent adverse event (CTC grade 3 or 4 in 6 patients), overall toxicity was generally mild. Four patients required hospitalization due to the toxicity, but 28 patients had been treated with TMZ at our outpatient clinic. These results suggested that the reported efficacy and toxicity profile of TMZ for the treatment of Japanese patients with recurrent malignant glioma is reproducible from the setting of clinical trials in the western countries.
