Using FDG PET/CT to Monitor Early Treatment Response in Glioblastoma Patients

Very Early Response Monitoring in Patients With Glioblastoma Undergoing Therapy Using FDG PET/CT

Not applicable Interventional Jonsson Comprehensive Cancer Center · NCT02902757

This study is testing if special scans can help doctors see how well chemotherapy is working for patients with glioblastoma just two days after starting treatment.

What this trial studies

This pilot clinical trial evaluates the use of fluordeoxyglucose (FDG) positron emission tomography (PET) and computed tomography (CT) to monitor very early therapy responses in patients diagnosed with glioblastoma. The study aims to assess changes in tumor glucose consumption within 48 hours of starting chemotherapy, which may indicate how well the treatment is working. Patients will undergo FDG PET/CT scans before and shortly after the initiation of therapy to correlate imaging results with clinical outcomes and survival rates.

Who should consider this trial

Good fit: Ideal candidates include patients with histologically confirmed high-grade glioma who are planning to start chemotherapy.

Not a fit: Patients with severe psychiatric illnesses or those unable to provide informed consent may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enable earlier identification of effective therapies for glioblastoma, potentially improving patient outcomes.

How similar studies have performed: Other studies have shown promise in using imaging techniques to assess early treatment responses, suggesting that this approach may be beneficial.
