JRCT ID: jRCTs032230489

Registered date:04/12/2023

Basic Information

• Recruitment status: Recruiting
• Health condition(s) or Problem(s) studied: Diffuse midline glioma,Deep seated glioma
• Date of first enrollment: 21/08/2024
• Target sample size: 10
• Study type: Interventional

Intervention(s)

The properties of 18F-BPA PET about the prediction of progression of DMG or DSG lesions at pretreatment status
Multi-institutional joint research

Outcome(s)

• Primary Outcome: Prediction rate of progression of DMG or DSG using 18F-BPA PET high uptake lesion

Secondary Outcome

Overall Survival
Progression free survival
The status of H3K27-altered in Immunohistochemical staining of the surgical specimens
RIng-like enhancement or T2WI high intensity lesions
The maximal diameter of the tumor on the pretreatment MRI
The tumor volume showing 18F-BPA PET hot uptake lesions at pretreatment state
18F-BPA PET uptake avidity
The relationship between H3K27-altered status and prognosis
The prediction rate of progression of DMG or DSG using 11C-MET-PET hot uptake lesions or 18F-BPA PET hot uptake lesions
The differences between tumor volume showing 18F-BPA PET hot uptake lesions and the progressive lesions on MRI
The evaluation of the property between 18F-BPA PET and 11C-MET PET
