Neuroblastoma is the most frequent extracranial childhood tumor, with an annual incidence of approximately 10.2 per million children. Staging of the disease can be done by different imaging strategies (CT, MRI, scintigraphy and PET/CT). Discrepancies may be observed among these different strategies resulting in different treatment strategies. The goal of this study is to assess the feasibility and safety of 68Ga-DOTATATE and to compare it to 123I-MIBG when investigating neuroblastoma.
This clinical trial is a pragmatic study aiming to evaluate the innocuity/safety profile of the PET radiotracer 68Ga-DOTA-TATE, and to establish the procedure as a routine standard-of-care diagnostic tool for all neuro-endocrine cancer patients. It is a single-center study, but with recruitment across all Canada. The trial is prospective, non-randomized, open-label and with no control group. The superiority of this procedure over the former standard-of-care (Octreoscan) was already established in previous and numerous studies across the world. As such, the current trial aims to gather data to further support the implementation of...
The study population consists of patients who undergo resection for somatostatin receptor-positive (SSTR-positive) CNS tumors, focusing on meningioma, and including esthesioneuroblastoma, hemangioblastoma, medulloblastoma, paraganglioma, pituitary adenoma, and SSTR-positive systemic cancers metastatic to the brain, such as small cell carcinoma of the lung. The study indication is to determine the diagnostic utility of 68Ga-DOTATATE PET/MRI in the diagnosis and management of patients with SSTR-positive CNS tumors, specifically whether 68Ga-DOTATATE PET/MRI demonstrates utility distinguishing between tumor recurrence and post-treatment...
Gastroenteropancreatic neuroendocrine tumours (GEP-NETs) are a heterogeneous group of neoplasms that arise from the endocrine cells of the gastroenteropancreatic tract. The diagnostic work-up of these tumours include Computed Tomography (CT), Endoscopic Ultrasound (EUS), Magnetic Resonance Imaging (MRI). The majority of these tumours express somatostatin receptors on their surface. For this reason, in addition to traditional imaging exams, diagnostic work-up of GEP-NETs should include a Positron Emission Tomography/CT with 68Ga labeled somatostatin analogues targeting somatostatin receptors with high sensitivity and specificity....
Somatostatin receptor (SSR) imaging is a critical component of clinical care for many patients being investigated for or with confirmed SSR positive tumors. In the past, 111In-octreotide imaging has been used for this purpose but it has been recently supplanted globally by SSR positron emission tomography (PET) imaging due to better image quality and higher diagnostic accuracy. This study will assess the safety and diagnostic effectiveness of 68Ga-HA-DOTATATE produced a the Edmonton Radiopharmaceutical Centre (ERC).
To determine if 68Ga-HA-DOTATATE PET/CT imaging is effective at diagnosing somatostatin positive tumors compared to conventional imaging [including CT, MRI, 111 In-pentetreotide Scans, 18F-FDG PET/CT, as available]
PSMA is highly expressed on the cell surface of the microvasculature of several solid tumors, including glioma. This makes it a potentially imaging target for the detection and grading of gliomas. This pilot study was designed to evaluate the diagnostic performance of 68Ga-P16-093, a novel radiopharmaceutical targeting PSMA, which was compared with MRI in the same group of glioma patients.
Based on the high expression of specific receptors on the surface of diseased tissues and neovascularization, noninvasive targeted molecular imaging can be used to visualize lesions in vitro by combining specific ligands labeled with short half-life isotopes. In this study, a novel dual-target imaging agent 68Ga-RM26-RGD was used for clinical study of tumor PET/CT imaging to further verify its clinical application value.
This clinical trial studies the use of 7-Tesla (7T) magnetic resonance imaging (MRI) in detecting melanoma that has spread to the brain (melanoma brain metastases). The standard MRI brain imaging is done on 3T or similar MRI machine, but the 7T MRI machine has a larger magnet which has been shown to have superior resolution of the brain and of non-cancerous brain lesions. Diagnostic procedures such as 7T MRI may help find and diagnose melanoma brain metastases earlier than standard 3T MRI.
Bevacizumab can be an effective treatment for individuals with NF2 and improve different nerve functions (like hearing, tinnitus or balance problems) and the quality of life of NF2 patients. However, bevacizumab is not effective in all patients or all tumors, at the cost of moderate toxicity and considerable financial burden. Therefore, this observational study will validate an imaging biomarker method to predict bevacizumab efficacy in order to avoid adverse effects and high costs in non-responders to bevacizumab treatment. Patients will undergo standard-of-care treatment with the sole addition of a pre-treatment 89Zr-Bevacizumab...
