Temozolomide plus radiotherapy improves survival in brain tumour
Temozolomide dose
Temozolomide was given as 75mg/m2 orally daily
for 42 days followed by 150–200mg/m2 daily on days 1 to
5 every 28 days for six cycles. The primary endpoint of the trial
was survival. |
Patients with glioblastoma, a form of brain cancer that is difficult to treat, show a survival benefit if temozolomide (Temodal) is given along with the standard treatment of radiation therapy following surgery, according to data presented at the American Society of Clinical Oncology annual meeting this week.
In this phase III trial, 573 patients with glioblastoma were randomised
to receive radiotherapy plus or minus concomitant temozolomide. The results
showed an improvement in overall survival at two years with 26 per cent
of patients alive in the temozolomide group and 10 per cent alive in
the radiation alone group (hazard ratio 0.63, 95 per cent confidence
interval 0.52–0.75, P<0.0001). Side effects of the therapy were
mild to moderate, including fatigue and occasional nausea.
Roger Stupp, University Hospital, Lausanne, Switzerland, and lead author,
said that temozolomide is usually used at the time of recurrence of glioblastoma
rather than during radiation therapy. “These data will probably
change the standard of care,” he said. Dr Stupp added that collaborative
research needs to continue to further improve outcome in these patients. |
