New imaging combo could outsmart aggressive brain cancer
NCT ID NCT06466031
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether adding a special PET scan (FET-PET) to standard MRI can better guide surgery and radiation for glioblastoma, the most aggressive brain tumor. About 189 adults with a single tumor will be randomly assigned to have treatment planning based on MRI alone or MRI plus FET-PET. The goal is to see if the combined imaging helps remove more active tumor tissue and delays regrowth, potentially improving survival.

Inclusion Criteria: * Single macroscopic tumor focus with the appearance of glioblastoma multiforme on MRI with contrast - contrast-enhancing lesion, completely or with central necrosis, with surrounding edema. * No history of cancer in other organs. No suspicious lesions on X-ray of the chest and abdomen (CT with contrast). * No clinical suspicion of brain abscess - no meningeal symptoms, signs of neuroinfection, fever, elevated inflammatory parameters. * Primary tumor, without neurosurgical, radiotherapy or oncology intervention. Prior tumor biopsy is allowed. * Tumor eligible for surgical treatment - craniotomy and tumor resection. * Age ≥ 18 years but \< 70 years old. * Quality of life assessment: KPS ≥ 70. * Informed patient consent to the study and proposed treatment. * No allergy to contrast agents used in PET and MRI. * No medical contraindications to neurosurgery - craniotomy and resection. Exclusion Criteria: * Multifocal brain tumor. * Recurrence of glioblastoma multiforme. * Clinical or radiological suspicion of brain metastasis or brain abscess. * Postoperative histopathological diagnosis other than WHO grade IV glioblastoma. * Medical contraindications to any surgery under general anesthesia. * Pregnancy, breastfeeding. * Known allergy to gadolinium contrast or radiopharmaceutical tracing agent.
