Overview
It has been reported that radiation therapy followed by PCV chemotherapy (procarbazine, lomustine and vincristine) could improve progression-free survival (PFS) and overall survival (OS) in patients with high-risk WHO grade 2 gliomas after surgery. However, procarbazine is not available in China. In clinical practice, Chinese doctors often use radiotherapy combined with temozolomide to treat these patients, though large-scale prospective studies are lacking. This trial aims to confirm whether RT combined with temozolomide can improve PFS and OS in patients with high-risk low-grade gliomas.
Interventions
- Drug Temozolomide
Concurrent chemotherapy is to receive oral temozolomide, 75 mg/m2 per day, during radiation therapy. Adjuvant chemotherapy will be treated with six cycles of temozolomide, 150 to 200 mg/m2 per day for five consecutive days, repeated every 4 weeks. There is a 28-day break during radiotherapy and adjuvant temozolomide. - Radiation intensity modulated radiation therapy
The radiation dose is 50-54 Gy given in 25-30 fractions (1.8-2.0 Gy once daily, 5 days per week).
Primary outcome measures
- Progression-free survival [Time frame: up to 120 months]
