Somatostatin receptor imaging with PET is the standard of care for patients with a neuroendocrine tumour (NET). Since therapy and imaging with somatostatin analogues utilize the same receptor, current guidelines recommend withdrawing long-acting somatostatin analogues for 3-4 weeks prior to somatostatin receptor PET imaging. The aim of this study is to prospectively assess the effect of lanreotide use on the uptake of Ga-DOTATATE intra-individually 1 day prior to and 1 day post injection of lanreotide.

[Lu]Lu-DOTATATE peptide receptor radionuclide therapy is used for treatment of neuroendocrine tumours. We investigated whether prolonging blood residence time of [Lu]Lu-DOTATATE with albumin binders c...
Prostate large cell neuroendocrine tumor is a rare disease. In this case, metastatic areas showing FDG uptake, somatostatin receptor positivity, and PSMA expression are shown in F-FDG PET/CT, Ga-DOTAT...
Lanreotide autogel is a synthetic somatostatin analogue which has been FDA and EMA approved for unresectable, well to moderately differentiated, locally advanced or metastatic gastroenteropancreatic ...
Objectives of the study are to analyze the correlation between [Ga]DOTATATE positron emission tomography (PET)/X-ray computed tomography (CT) measurements and various biological characteristics of gas...
Primary hepatic neuroendocrine tumours (PHNET) were first described by Edmondson et al. in 1958 and are rare, accounting for only 0.3% of all neuroendocrine tumours. Only several hundred cases have be...
A Ga-HA-DOTATATE PET/CT scan is a nuclear medicine test used to create pictures of the whole body that will show where somatostatin receptors are found, including on tumours. Somatosta...
The objective of the PRELUDE study is to describe the use of lanreotide Autogel® (LAN ATG) combined with Peptide Receptor Radionuclide Therapy (PRRT) in the treatment of progressive neuro...
To evaluate, in patients with progressive neuroendocrine tumours who are not eligible to be treated with either surgery or chemotherapy at the moment of study inclusion, the efficacy of la...
This study aims to explore the efficacy and safety of lanreotide Autogel® 120 mg administered every 14 days in subjects with grade 1 or 2, metastatic or locally advanced, unresectable pan...
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 t...
A furancarbonitrile that is one of the SEROTONIN UPTAKE INHIBITORS used as an antidepressant. The drug is also effective in reducing ethanol uptake in alcoholics and is used in depressed patients who also suffer from tardive dyskinesia in preference to tricyclic antidepressants, which aggravate this condition.
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.
Drugs that inhibit the transport of neurotransmitters into axon terminals or into storage vesicles within terminals. For many transmitters, uptake determines the time course of transmitter action so inhibiting uptake prolongs the activity of the transmitter. Blocking uptake may also deplete available transmitter stores. Many clinically important drugs are uptake inhibitors although the indirect reactions of the brain rather than the acute block of uptake itself is often responsible for the therapeutic effects.
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 acidic protein found in the NEUROENDOCRINE SYSTEM that functions as a molecular chaperone for PROPROTEIN CONVERTASE 2.
