A Novel Target Delineation Scheme in High-grade Glioma Patients: a Randomized Single-blind Clinical Trial

Study Purpose

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.

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT06215495
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Arms & Interventions

Arms

Experimental: reduced CTV (clinical target volume) and PTV (planning target volume)

Active Comparator: EORTC CTV (clinical target volume) and PTV (planning target volume)

Interventions

Radiation: - reduced target volume

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

Radiation: - EORTC (European organisation for research and treatment of cancer) target volume

delineate according to EORTC guideline
