How long do patients usually stay on chemotherapy for brain cancer like glioma?

Temozolamide: Is used in lower doses as a daily oral drug during 6 weeks of radiotherapy, and then for 6 cycles afterward in a higher dose schedule.

Temodar (temozolomide): The best recommended treatment at this time is concurrent radiation and temodar (temozolomide) for 6 weeks followed by a five day cycle of temodar (temozolomide) each month for 6 months. There are many that continue the monthly cycles of temodar (temozolomide) until there is evidence for recurrence. At the time of recurrence, there is an option to try another chemotherapeutic agent.
