18F-FDOPA PET in Neuroendocrine Tumours

Thyroid CancerMedullary5 more

Neuroendocrine tumours (NETs) are a group of neoplasms generally arising from the gastroenteropancreatic tract. They are usually slow growing, have low malignant potential, and often go unnoticed until they become metastatic. The correct treatment approach is dependent on the extent of the disease, however surgical approaches and systemic therapy can be curative. Combined positron emission tomography/computed tomography (PET/CT) using the radiotracer 18F-6-L-fluorodihydroxyphenylalanine (18F-FDOPA) has been shown to be a promising non-invasive technique to help localizing NETs and guide their treatment.

A Study of 18F-AlF-NOTA-octreotide PET/CT for Imaging Neuroendocrine Neoplasms

Neuroendocrine Neoplasm

The aim of this study is to investigate the clinical value of [18F]aluminum fluoride-1,4,7-triazacyclononane-1,4,7-triacetic acid-octreotide(18F-AlF-NOTA-octreotide ) positron emission tomography / computed tomography (PET/CT) in patients with neuroendocrine neoplasms (NENs).

Potential Molecular Predictors of Response to Novel Therapies in Metastatic Pancreatic Neuroendocrine...

Pancreatic Neuroendocrine Cancer

Sunitinib and everolimus are two new treatments approved in 2011 for patients with pancreatic neuroendocrine tumors (NETs). In addition, some traditional chemotherapies are often used to treat pancreatic NETs. Traditional chemotherapy is also known as "cytotoxic therapy" and works by killing cells that are actively dividing. There have been no studies to compare the different types of treatment. Since the patient is eligible for treatment with either sunitinib, everolimus or traditional chemotherapy it can help us identify factors that may help future patients benefit from these therapies.

The Reproducibility Of Diffusion Weighted Magnetic Resonance Imaging For Neuroendocrine Tumor Liver...

Gastro-enteropancreatic Neuroendocrine TumorSecondary Malignant Neoplasm of Liver

Imaging with CT (Computed Tomography) or MRI (Magnetic Resonance Imaging) is normally used to see how tumors respond to treatment. If tumors shrink after therapy, doctors continue with the same treatment. On the other hand, growing tumors in a patient can bring about a change in therapy. Unfortunately, it often takes three to six months, or even longer before the investigators see tumors shrink or grow on scans. Doctors are looking for new imaging tools that can look at how tumors respond early on during treatment. This study will help us decide if such an MRI technology called DWI (Diffusion Weighted Imaging) can be used as a helpful imaging tool.

PET-CT Imaging of Neuro-endocrine Tumors and Preliminary Clinical Evaluation

Neuroendocrine Tumors

Through the investigators involvement in an international consortium, the investigators had the opportunity to acquire a new type of synthetizer for the radiolabelling of such tracers. The investigators propose in this project to develop on their site, the radiosynthesis of 68Ga-DOTATOC and to evaluate prospectively the diagnosis of neuroendocrine tumors, compared with the current imaging OctreoScan®. The objectives of this project are: - to validate the radiosynthesis of 68Ga-DOTATOC on their site with a new synthetizer - and clinically evaluate, through a prospective preliminary study, the diagnostic accuracy of PET-CT with 68Ga-DOTATOC in comparison with other standard imaging examinations.

GLUT1: A Novel Tool re fl Ecting Proliferative Activity of Lung Neuroendocrine Tumors

Lung Tumor

Lung neuroendocrine tumor (LNT) represents approximately 20% of all lung cancers. The classification of LNT relies upon morphology. Recently, in the World Health Organization (WHO) classification, Ki-67 rate has been proposed for classi fication. It is, however, known that Ki-67 count has a poor interlaboratory reproducibly. For that reason, our team has looked for a new biomarker. GLUT1 protein a facilitative glucose transporter protein which has ubiquitous expression in mammalian. GLUT1 is overexpressed in many human cancers. But, no study has evaluated the GLUT1 staining as an aid diagnosis in LNT. The team have assessed the GLUT1 immunohistochemical staining in 36 LNT and to assess its diagnostic value.

Impact of Peptides and Chelators on Somatostatin Receptor Antagonists

Neuroendocrine Tumors

Somatostatin receptor antagonists are emerging agents in molecular imaging of neuroendocrine tumors. There're two main antagonist peptides, namely JR11 and LM3, which can be coupled with different chelators, DOTA and NODAGA. Previous studies by our and other groups have revealed the different diagnostic performances of these tracers. However, head-to-head comparison data is still missing. In this study, we aim to evaluate the diagnostic performance of four different antagonists, that is, NODAGA-LM3, DOTA-LM3, and NODAGA-JR11, all labeled with gallium-68.
