NCT02020720

Brief Summary

This pilot clinical trial studies fluorine F 18 fluorodopa (18F-DOPA)-positron emission tomography (PET) in planning surgery in patients with gliomas. New imaging procedures, such as 18F-DOPA-PET scan, may help find gliomas and may help in planning surgery.

Outcome Measures

Primary Outcomes (1)

  • Ratios of maximum tumor standardized uptake value (SUVmax) normalized to mean SUV (SUVmean) of T/N

    To determine the optimal PET threshold for distinguishing HGG from LGG brain tissue, receiver operating characteristic (ROC) analysis and the Youden's index (sum of the sensitivity and specificity - 1) will be used. The Youden's index will be calculated for each possible T/N threshold. The final ROC area under the curve (AUC) value and confidence intervals will be estimated using ROC analysis methods for clustered continuous data as described by Obychowski.

    Up to 1 year

Secondary Outcomes (5)

  • Differences in volumes generated from biopsy-validated thresholds evaluated by 18F-DOPA-PET, pMRI, and DTI

    Up to 5 years

  • Histologic grade of the specimen defined as HGG, LGG, or non-malignant brain tissue

    Up to 5 years

  • MRI contrast enhancement values

    Up to 5 years

  • Progression free survival

    The time from study entry to progression, assessed up to 5 years

  • Proportion of patients whose maximum 18F-DOPA uptake samples are in agreement with the final diagnostic grade

    Up to 5 years

Other Outcomes (3)

  • Accurate identification of the highest grade/highest density disease

    Up to 5 years

  • Accurate identification of tumor extent

    Up to 5 years

  • Role of metabolic imaging in neurosurgical resection planning

    Up to 5 years

Study Arms (1)

Diagnostic (18F-DOPA-PET)

EXPERIMENTAL

Within 1 week of biopsy or resection, patients undergo 18F-DOPA PET/CT scan and pMRI and DTI at baseline. Patients then undergo stereotactic craniotomy or image-guided biopsy.
