IDH mutation and MGMT gene changes in glioblastoma: findings from a forward-looking patient registry

Abstract

Tumors with both isocitrate dehydrogenase mutations and O6-methylguanine-DNA methyltransferase promoter methylation showed a median overall survival of 35.8 months for glioblastoma patients treated with Temozolomide and Radiation Therapy.

  • Glioblastoma patients with both isocitrate dehydrogenase mutations and MGMT promoter methylation had the most favorable progression-free survival and overall survival.
  • Patients with either isocitrate dehydrogenase mutations or MGMT promoter methylation exhibited intermediate outcomes.
  • Wild type IDH1 glioblastomas with unmethylated MGMT promoter had the poorest survival outcomes.
  • Treatment with Temozolomide plus Radiation Therapy improved overall survival and progression-free survival for wild type IDH glioblastomas compared to Radiation Therapy alone.
  • Isocitrate dehydrogenase mutations appeared to confer resistance to Temozolomide, as shown by increased resistance in laboratory models.
