简要总结
This is a research study to collect information regarding usefulness of positron emission tomography (PET) scans using a special dye called 68Ga-DOTATATE for patients with neuroendocrine tumours by determining the number of of patients whose clinical management was changed as a result of the scans.
详细描述
When patients are suspected of having neuroendocrine tumours, they will usually undergo various imaging scans such as computed tomography (CT) scan and magnetic resonance imaging (MRI), and octreotide scintigraphy (octreoscan) to try to identify the primary tumour. During the patients' course of disease, they will continue to have various CT, MRI, and/or octreoscans. Sometimes, despite using scans, laboratory tests, and examination, it is still difficult to properly diagnose neuroendocrine tumours.
Doctors have found that most neuroendocrine tumours make too much of a hormone called somatostatin on their cell surface. Because of this doctors have been using positron emission tomography (PET) scans using a special contrast dye called 68Ga-DOTATATE in hopes of better diagnosing and managing neuroendocrine tumours. 68Ga-DOTATATE can label the cells that have somatostatin (such as neuroendocrine tumour cells) so that the PET scan can take better pictures and doctors can better diagnose and manage the disease.
However, despite 68Ga-DOTATATE PET scans showing promise, it is still not widely accessible. Because of this, researchers are creating a registry for patients who may need 68Ga-DOTATATE PET scans to:
- Identify their primary tumour where the doctor suspects is a neuroendocrine tumour
- Staging of the neuroendocrine tumour
- Restage the tumour prior to surgery/radiotherapy or help to assess the tumour where standard scans such as CTs, MRIs, or octreoscans are not properly showing your tumours despite other clinical or laboratory tests showing that your disease has progressed
- For other issues when confirmation of site of disease and/or disease extent may impact clinical management of the neuroendocrine tumour.
This registry help the participant's treating physician to obtain approval for the participant to undergo 68Ga-DOTATATE PET scans for their neuroendocrine tumour.

入选标准
- •Able to undergo PET/CT without sedation
- •Any of the following indications:
- •Group A. Identification of primary tumor: For the initial diagnosis of patients with clinical (e.g., signs, symptoms) and/or biochemical (e.g., tumor markers) suspicion of neuroendocrine tumours (NETs) but for whom conventional imaging is negative or equivocal or for whom biopsy is not easily obtained.
- •Group B. Staging: For the staging of patients with localized primary NETs and/or limited metastasis where definitive surgery is planned.
- •Group C. Restaging: Restaging of patients with NET where surgery or peptide-receptor radiotherapy (PRRT) is being considered; OR, where conventional imaging is negative or equivocal at time of clinical and/or biochemical progression.
- •Group D. As a problem-solving tool: As a problem-solving tool in patient with NET when confirmation of site of disease and/or disease extent may impact clinical management.
- •Approved by a review panel if Group D.
