Safety and feasibility of long-term temozolomide treatment in patients with high-grade glioma

We surveyed neuro-oncologists regarding patients treated with temozolomide for at least 12 cycles or 12 months. Patients receiving first-line temozolomide for a median 13 cycles had a median progression-free survival (PFS) of 14 months. Patients with recurrent disease receiving a median 14 cycles had a median PFS of 15.5 months. A small percentage of patients experienced grade III to IV toxicity. These results suggest that long-term treatment with temozolomide is feasible and well tolerated.
