Maintenance therapy with 13-cis retinoid acid in high-grade glioma at complete response after first-line multimodal therapy--a phase-II study.

Background: Approximately 5% of patients with malignant glioma achieve complete response (CR) after first-line combined modality treatment. Although these patients will invariably suffer from tumor recurrence, they usually do not receive any further treatment to maintain remission. According to in vitro and in vivo clinical studies, 13-cis retinoic acid (cRA) may be a promising agent for maintenance therapy in these patients.

Pegylated liposomal doxorubicin-efficacy in patients with recurrent high-grade glioma.

Background: Doxorubicin exhibits high efficacy in malignant glioma cell cultures. Nonetheless, as a standard formulation, doxorubicin has not been used clinically, due to poor penetration of the blood-brain barrier. Furthermore, doxorubicin is known to induce tumor resistance genes.

Salvage therapy in patients with glioblastoma: is there any benefit?

Background: Survival after first-line therapy is poor for patients with glioblastoma. The role of second-line treatment for recurrent disease is controversial. The authors studied the outcome in a subset of patients with glioblastoma who were selected for an aggressive reintervention strategy at the time of progression.
