Temozolomide provided significant and clinically meaningful benefit in MGMT gene promoter methylation glioblastoma. However, in unmethylated patients, the effect of Temozolomide is limited. The aim of this study is to compare the effect of Cisplatin plus Temozolomide and Temozolomide in patients with MGMT gene promoter unmethylation glioblastoma

60 Patients with glioblastoma were recruited for this study based on the following eligibility criteria: Age between 18 and 70, performance status of 0-1 (Eastern Cooperative Oncology Group performance status), histologically confirmed MGMT gene promoter unmethylation glioblastoma, no cerebrospinal fluid and distant metastatic disease. All patients had adequate hematologic, hepatic, and renal function. Patients younger than 18 years; patients with a prior (i.e. within 5 years) or synchronous malignancy, other than non-melanoma skin cancer; and those with significant comorbidities were excluded.

60 patients were randomly divided into two groups and compared the difference of efficacy between the two groups

Inclusion Criteria:

• Age between 18 and 75, performance status of 0-1 (Eastern Cooperative Oncology Group performance status), histologically confirmed MGMT gene promoter unmethylation glioblastoma no cerebrospinal fluid and distant metastatic disease. adequate hematologic, hepatic, and renal function

Exclusion Criteria:

• younger than 18 years; with a prior (i.e. within 5 years) or synchronous malignancy, other than non-melanoma skin cancer; and those with significant comorbidities
