Adding Chemotherapy to Radiotherapy Does Not Appear to Affect Cognitive Function in Patients With Low-Grade Glioma

The addition of PCV (procarbazine [Matulane], lomustine [CeeNu], vincristine) chemotherapy to radiotherapy improves progression-free survival in patients with grade 2 glioma, but the potential effect of treatment intensification on cognitive function is a concern in this group of patients with good ...

Imaging Studies May Predict Tumor Response to Antiangiogenic Drugs

Advanced imaging techniques may be able to distinguish which patients' tumors will respond to treatment with antiangiogenic drugs and which will not. In a report published online in PNAS, researchers studied patients with newly diagnosed glioblastoma who were treated with the antiangiogenic agent...

RTOG 0525 Subanalysis Finds Worse Outcomes With Dose-Dense vs Standard Adjuvant Temozolomide in Glioblastoma

A phase III trial (Radiation Therapy Oncology Group [RTOG] 0525; N = 833) comparing dose-dense vs standard-dose temozolomide maintenance in newly diagnosed glioblastoma showed no differences in overall survival or progression-free survival between treatments. A substudy of the trial, reported in...

No Benefit of Dose-Dense vs Standard Temozolomide in Newly Diagnosed Glioblastoma, MGMT Methylation Associated With Better Survival

Dose-dense temozolomide results in depletion of O6-methylguanine-DNA methyltransferase (MGMT)—a potential determinant of treatment response—in blood mononuclear cells and possibly in tumors. In a phase III trial (Radiation Therapy Oncology Group [RTOG] 0525) reported in the Journal ...

Survival Advantage Seen in Glioblastoma Patients Taking Valganciclovir

Valganciclovir (Valcyte), a drug used to treat cytomegalovirus (CMV) eye infections in people with HIV/AIDS, may lengthen survival in patients with glioblastoma, a Swedish study has found. The researchers evaluated 50 patients with glioblastoma who received valganciclovir as an add-on to standard...

New Laser-Based Tool Could Dramatically Improve the Accuracy of Brain Tumor Surgery

A new laser-based technology may make brain tumor surgery much more accurate, allowing surgeons to tell cancer tissue from normal brain at the microscopic level while they are operating, and avoid leaving behind cells that could spawn a new tumor. In a new paper published in Science Translational...

Brain Cancer Survival Improved Following FDA Approval of Bevacizumab, Mayo Study Finds

A new population-based study has found that patients with glioblastoma who died in 2010, after the FDA approval of bevacizumab (Avastin), had lived significantly longer than patients who died of the disease in 2008, prior to the conditional approval of the drug for the treatment of  brain...

Study Suggests Neural Stem Cells May Regenerate After Radiation Therapy

Scientists have long believed that healthy brain cells, once damaged by radiation designed to kill brain tumors, cannot regenerate. But new research in mice suggests that neural stem cells, the body's source of new brain cells, are resistant to radiation, and can be roused from a hibernation-like...
