Brief Summary

MRI is used in clinical routine for diagnosing brain tumors, but has limitations in identifying tumor grade, true tumor extension and differentiate viable tumor tissue from treatment induced changes and recurrences. Amino acid PET has demonstrated a great potential for defining true tumor volume, differentiate viable tumor tissue from postoperative changes or radiation necrosis, selection of biopsy site, non-invasive grading of gliomas and for treatment planning and therapy response assessment. By combining PET with MRI, the diagnostic accuracy can improve significantly for these patients. More research is however needed to compare the most promising amino acid PET tracers in patients with glioma, but also to assess the diagnostic value of amino acid PET in patients with different brain metastases, where the knowledge concerning the uptake characteristics is limited. Three of the most promising amino acid tracers (\[11C\]-methyl-methionine (11C-MET), \[18F\] fluoro-ethyl-tyrosin (18F-FET) and anti-1-amino-3-\[18F\]fluorocyclobutane-1-carboxylic acid (18F-FACBC)) will be evaluated in 3 substudies in this project; WP1 Aminoacid PET/MRI in low and high grade glioma; WP2 Role of 11C-MET in high-grade glioma Gamma Knife® radiosurgery; and WP3 Amino acid PET in brain metastasis. The main aim of the study is to improve diagnostic accuracy, histopathological tissue sampling, delineation of tumor extent and therapy response assessment in gliomas and brain metastases with amino acid PET/MRI.

Outcome Measures

Primary Outcomes (1)

  • Diagnostic accuracy in detecting brain tumor tissue at baseline

    Diagnostic accuracy, sensitivity, specificity, positive-and negative predictive values of PET, contrast-enhanced MRI (MRICE) and combined PET/MRI will be calculated by comparing images to histopathological results for the large non-localized biopsies as well as to the image-localized biopsies taken prior to resection.

    Baseline

Secondary Outcomes (2)

  • Diagnostic accuracy using dynamic PET

    Baseline

  • Differentiation between recurrence and treatment related changes using PET/MRI

    4-6 months

Study Arms (2)

Glioma

20 low-grade (LGG) and 40 high-grade glioma (HGG) patients will be included from the Department of Neurosurgery at St. Olavs Hospital and the Department of Neurosurgery at the University hospital of North Norway and examined with 18F-FACBC PET/MRI at baseline and 4-6 months after surgery. Furthermore, 10 of the LGG patients and 10 of the HGG patients will be examined with an additional 18F-FET PET/MRI at baseline for comparison with 18F-FACBC. 30 recurrent HGG patients will be recruited from the Department of Neurosurgery and the Department of Oncology at the Haukeland University Hospital. These patients will be examined with 11C-MET PET/MRI at treatment/baseline and 1 month after radiosurgery.

Other: Diagnostic Amino acid PET/MRI examination

Brain Metastases

Patients with brain metastases (18F-FACBC: n=20, 18F-FET: n=20 and 11C-MET: n=30) will be included from the Department of Neurosurgery at St. Olavs Hospital, the Department of Neurosurgery at Haukeland University Hospital and the Department of Neurosurgery at the University hospital of North Norway, and examined with amino acid PET/MRI at baseline, 1 month after surgery/stereotactic radiosurgery (St. Olavs Hospital/UNN: Linac, Haukeland University Hospital: Gamma Knife® radiosurgery) and at suspicion of recurrence.

Other: Diagnostic Amino acid PET/MRI examination
