Temozolomide (Temodar)

Salvage temozolomide for prior temozolomide responders.

BACKGROUND Temozolomide (TMZ) often is used as adjuvant or first-line therapy for patients with glioma. Because of potential hematologic complications, it usually is discontinued after 12-18 cycles, even in responders. Subsequent salvage therapies are reported to have limited efficacy at the time of disease recurrence. In the current study, the authors assessed the outcome and complications of ...

Treatment Advances for Glioblastoma: Tumor Markers and Targeted Treatments

Although malignant brain tumors affect thousands of persons each year, treatment has not significantly advanced. For 3 decades, the standard of care was palliative surgery, radiation, and chemotherapy. Of these, radiotherapy was the only proven way to lengthen survival time. However, since 2005 the standard of treatment has changed thanks to studies showing positive results from daily temozolom...

Temozolomide and MGMT forever?

Temozolomide-Induced Myelodysplasia

A patient who had received temozolomide (TMZ) as a single agent in treatment of malignant glioma developed therapy-induced myelodysplasia (T-MDS). TMZ is an orally active imidazotetrazine which methylates guanine residues in DNA, ultimately causing single and double-strand DNA breaks leading to apoptotic cell death. TMZ does not chemically cross-link DNA and is considered a nonclassical alkylat...

Temozolomide in malignant glioma

Glioblastoma multiforme WHO grade IV (GBM) is the most aggressive malignant glioma and the most frequent primary tumor of the central nervous system. The median survival of newly diagnosed GBM patients was between 9 to 12 months prior to treatment with temozolomide being introduced. Primary resection that is as complete as possible is recommended for malignant glioma. Conventional fractionated ...
