The specific aim is of this study is to gain a better understanding of the patient characteristics, treatment responses, survival outcomes, and adverse events associated with PRRT in patients with gastroenteropancreatic primary NETs.
Neuroendocrine tumors (NETs) make up a large range of malignancies that arise from neuroendocrine cells in multiple organs of the body. Hallet et al conducted a large population-based study that demonstrated that 21% of NET patients presented with metastatic disease and another 38% developed metastases after resection of the primary tumor (Hallet et al., 2015). This burden demonstrates the need for effective systemic therapy for advanced NETs. Options for systemic therapy include peptide receptor radionuclide therapy (PRRT).
A need for more prospective series are needed on treatment responses and survival outcomes related to gastroenteropancreatic primary NETs treated with PRRT was identified. Thus the purpose of this study is to collect clinical data related to treatment of gastroenteropancreatic primary NETs s with PRRT. Clinical data related to patient characteristics, treatment responses and survival outcomes related to the treatment of gastroenteropancreatic primary NETs with PRRT and on adverse events and complications related to PRRT treatment will be collected.

Tumors whose cells possess secretory granules and originate from the neuroectoderm, i.e., the cells of the ectoblast or epiblast that program the neuroendocrine system. Common properties across most neuroendocrine tumors include ectopic hormone production (often via APUD CELLS), the presence of tumor-associated antigens, and isozyme composition.
A group of carcinomas which share a characteristic morphology, often being composed of clusters and trabecular sheets of round "blue cells", granular chromatin, and an attenuated rim of poorly demarcated cytoplasm. Neuroendocrine tumors include carcinoids, small ("oat") cell carcinomas, medullary carcinoma of the thyroid, Merkel cell tumor, cutaneous neuroendocrine carcinoma, pancreatic islet cell tumors, and pheochromocytoma. Neurosecretory granules are found within the tumor cells. (Segen, Dictionary of Modern Medicine, 1992)
A G-protein-coupled, proteinase-activated receptor that is expressed in a variety of tissues including ENDOTHELIUM; LEUKOCYTES; and the GASTROINTESTINAL TRACT. The receptor is activated by TRYPSIN, which cleaves off the N-terminal peptide from the receptor. The new N-terminal peptide is a cryptic ligand for the receptor. The uncleaved receptor can also be activated by the N-terminal peptide present on the activated THROMBIN RECEPTOR and by small synthetic peptides that contain the unmasked N-terminal sequence.
A 38-kDa integral membrane glycoprotein of the presynaptic vesicles in neuron and neuroendocrine cells. It is expressed by a variety of normal and neoplastic neuroendocrine cells and is therefore used as an immunocytochemical marker for neuroendocrine differentiation in various tumors. In ALZHEIMER DISEASE and other dementing disorders, there is an important synapse loss due in part to a decrease of synaptophysin in the presynaptic vesicles.
An analog of GLUCAGON-LIKE PEPTIDE 1 and agonist of the GLUCAGON-LIKE PEPTIDE 1 RECEPTOR that is used as a HYPOGLYCEMIC AGENT and supplemental therapy in the treatment of DIABETES MELLITUS by patients who do not respond to METFORMIN.
