Outcome Measures

Primary Outcomes (2)

  • Qualitatively measure the visual appearance of target lesion to cranial blood pool using the maximum SUV ratio to compare results from Ga-68-DOTATATE and -DOTATOC PET.

    Compare visual appearance qualitatively using the maximum SUV ratio of target lesion to cranial blood pool (i.e. superior sagittal sinus reference region) of DOTATATE and DOTATOC PET scans in patients with meningioma. Based on our pilot clinical case series, the following reference regions will be evaluated: 1. Suspected meningioma; 2. Pituitary gland; 3. Superior sagittal sinus; 4. Brain parenchyma. Dynamic PET will be acquired and data will be analyzed including comparison of tissue-activity curves and Patlak analysis, as established by the PI in a pilot cohort. Extent of meningioma based on Ga-68-DOTATATE- and DOTATOC PET/CT will be compared to extent of disease as determined by MRI.

    Over 12 months

  • Quantitatively measure the visual appearance of target lesion to cranial blood pool using the maximum SUV ratio to compare results from Ga-68-DOTATATE and -DOTATOC PET.

    Compare visual appearance quantitatively using the maximum SUV ratio of target lesion to cranial blood pool (i.e. superior sagittal sinus reference region) of DOTATATE and DOTATOC PET scans in patients with meningioma. Qualitative analysis will include evaluation by board certified radiologists with expertise in nuclear medicine/ molecular imaging who will be blinded to the radiotracer injected. Quantitative analysis will include extraction of the ratio of lesion's SUVmax values/reference regions.

    Over 12 months

Secondary Outcomes (4)

  • Compare molecular biomarker (Ki67) analysis to Ga-68-DOTATATE PET and Ga-68-DOTATOC PET by measuring biomarker histopathology (Ki67) results to the maximum SUV ratio of target lesion to cranial blood pool.

    Over 12 months

  • Compare molecular biomarker (EGFR) analysis to Ga-68-DOTATATE PET and Ga-68-DOTATOC PET by measuring biomarker histopathology (EGFR) results to the maximum SUV ratio of target lesion to cranial blood pool.

    Over 12 months

  • Compare molecular biomarker (progesterone receptor) analysis to Ga-68-DOTATATE PET and Ga-68-DOTATOC PET by measuring biomarker histopathology (progesterone receptor) results to the maximum SUV ratio of target lesion to cranial blood pool.

    Over 12 months

  • Compare molecular biomarker (SSTR2 expression) analysis to Ga-68-DOTATATE PET and Ga-68-DOTATOC PET by measuring biomarker histopathology (SSTR2 expression) results to the maximum SUV ratio of target lesion to cranial blood pool.

    Over 12 months

Study Arms (1)

Patients with Meningioma

EXPERIMENTAL

Subjects with suspected meningioma planned for surgery who meet the inclusion and exclusion criteria.

Drug: Ga-68- DOTATATEDrug: Ga-68-DOTATOC

Interventions

The study intervention consists of two PET scans that will be performed using two different radiotracers, 68-Ga-DOTATATE and 68-Ga-DOTATOC. Ga-68-DOTATATE and 68-Ga-DOTATOC are PET radiotracers targeting somatostatin receptors. The study intervention consists of 2 PET scans that will be performed at least 24h apart using 68-Ga-DOTATATE and 68-Ga-DOTATOC radiotracers, in patients with suspected meningioma that are planned for subsequent surgery.

Model Details: The study intervention consists of 2 PET scans that will be performed at least 24h apart using 68-Ga-DOTATATE and 68-Ga-DOTATOC radiotracers, in patients with suspected meningioma that are planned for subsequent surgery. Visit 1 Patients will undergo a 68-Ga-DOTATATE PET/CT or PET/MR scan as standard of care, or as part of a separate research study. Visit 2 At least 24h and up to 4 weeks apart from Visit 1, patients will undergo 68Ga-DOTATOC PET/CT scan. Follow-up Phase Patients enrolled in the study are planned for surgery as part of SOC. After the two scans, patients will undergo surgery and a histopathologic analysis of the resected tumor will be performed. The histopathology results will be used to correlate molecular biomarkers with imaging parameters. During the follow up period a review of clinical and imaging records related to the diagnosis will be conducted by the research team as part of the study during the follow- up period.
