A Novel Target Delineation Scheme in High-grade Glioma Patients: a Randomized Single-blind Clinical Trial
A Novel Target Delineation Scheme Based on RTOG(Radiation Therapy Oncology Group) and EORTC(European Organisation for Research and Treatment of Cancer) Guidelines Impact on Survival Time and Radiotherapy Complications in High-grade Glioma Patients: a Single-center Randomized Single-blind Clinical Trial
Zhujiang Hospital
88 participants
Feb 18, 2024
INTERVENTIONAL
Conditions
Summary
The main question it aims to answer are: 1. whether the new target delineation scheme can improve Progression-free Survival 2. whether it can reduce the incidence of radiation complications in high-grade glioma patients. Participants in trial group will be performed radiotherapy of new target delineation method after the completion of the operation within 4-6 weeks., while participants in the control group be performed radiotherapy of EORTC(European organisation for research and treatment of cancer) target delineation method.Temozolomide 75 mg / ( m² · d ) will be given to both groups of patients during radiotherapy. After radiotherapy, its dose changes to 150 \~ 200 mg / ( m² · d ) for 5 days and stopped for 23 days as a cycle. There are 6 cycles in total.

Interventions
Delineate residual tumor(GTVp) and tumor bed(GTVtb) on enhanced contrast CT-MRI(T2 fluid attenuated inversion recovery, T2 FLAIR) fusion images. GTVtb and GTVp are expanded by 1cm to CTV\_6000. The clinical target volume\_6000 cGy (CTV\_6000) is partially reduced beyond the skull and midline. According to the CT-MRI(T2 FLAIR) fusion images, the edema area that cannot be seen on contrast-enhanced CT and only can be seen on MRI should be included. If CTV\_6000 includes thalamus, basal ganglia, brainstem or motor cortex, dose of these areas will be limited no more than 54Gy
delineate according to EORTC guideline
