Active clinical trials for "Neuroendocrine Tumors"

Reflexion on the therapeutic strategies to implement in patients at the end of life is advancing rapidly in France. However, beyond the choices presented to patients, sometimes even the decision to carry on, to limit or to stop treatments is also questioned. This decision is subjective; it is influenced by the patient's representation system (emotions, beliefs, values, practices, etc). In addition, even though he or she is the focus of the decision, the patient is not alone; other actors, accompanying the patient, play an important role in the final decision making. These actors, namely the doctors and close relatives, are also influenced in their decision making. This coexistence of representation systems may interfere with objective indicators that help in decision making (functional, clinical and biological) or with the knowledge acquired by doctors in their training and may complicate the decision-making process.

The NET-PACS trial is a Prospective Assessment of patients with neuroendocrine tumors and current or prior history of Carcinoid Syndrome or diarrhea undergoing peptide receptor radionuclide therapy with or without telotristat ethyl. The main goal of the study is to demonstrate the feasibility of serial in-depth assessment of patients with neuroendocrine tumors and current or prior history of carcinoid syndrome or diarrhea undergoing treatment with PRRT using telotristat ethyl compared to placebo. We aim to report and describe from a patient's perspective the multi-faceted impact of carcinoid syndrome in patients with NETs and the changes on treatment while getting PRRT using telotristat ethyl compared to placebo.

This single arm study will evaluate whether Xermelo (telotristat ethyl) associated weight gain is affects lean body mass, dietary intake, and physical and cognitive functioning among neuroendocrine tumor (NET) patients with a history of carcinoid syndrome.

The main aim of this study is to assess the Progression-Free Survival (PFS) at 12 months of Lanreotide Autogel 120 mg use when administered as part of routine GEP-NET treatment and to follow patient treatment pathways, identify prognostic factors of PFS, evaluate patient's QoL, and patient's and clinician's satisfaction with treatment in routine long-term care setting. The study will provide real-world evidence on the use of Lanreotide Autogel 120 mg and will provide information on topics such as optimization of product usage and identification of best practices and will provide evidence on product effectiveness in a realistic setting.

In an individual cancer patient extensive genetic and phenotypic variation exists between and within tumor lesions. Tumour load in NET patients can be measured with fluorine-18-L-dihydroxyphenylalaninepositron emission tomography (18F-DOPA-PET) scan. This aim of the study is to investigate heterogeneity between tumor lesions within patients with intestinal NET by determining the differences in tracer uptake measured on a 18F- DOPA-PET scan retrospectively.

The purpose of this study is to evaluate the utility of the QLQ-GINET21 in making clinical and therapeutic decisions.

Data from this study will contribute additional knowledge regarding patient outcomes and direct somatostatin analogue (SSA) treatment related costs in clinical practice in the Nordic countries. Such knowledge can be of importance in a treatment decision, decision support for development of care, follow up and training of both patients and primary care nurses.

euroendocrine tumors (NETs) are neoplasms that originate from diffuse neuroendocrine system which consist about 17 types of different neuroendocrine cells. These cells combine properties of nerve cells with properties of endocrine cells, that is they receive neuronal signal and produce hormones.The most common locations for NETs are the lungs and organs of the gastroenteropancreatic (GEP) system, however they can be found in any other organ in the body . Clinically, functional NET cells secrete hormones which cause symptoms such as diarrhea or flushing, however non-functional NET cells also exist posing a challenge in the identification and diagnosis of the disease . Besides surgery to remove the tumor, there are numerous of treatment options for systemic handling of the NETs. These treatments include: somatostatin analogues, interferon, chemotherapy, transarterial (chemo) embolisation, radiofrequency ablation, sunitinib, everolimus and radionuclide targeted therapy. The choice of treatment depends on the correct characterization of the NET, primary tumor location, tumor subtype, grade and stage of the disease . Biomarkers for NETs serve a critical role in the diagnosis stage, where it is highly important to identify the NET type and precise location. Furthermore, selecting the correct biomarkers for monitoring the disease is important to predict response for treatment and allow the choice of the right treatment from the large variety of treatment options. NET biomarkers include circulating biomarkers such as Chromogranin A, Ki67, Neuron Specific Enolase (NSE), 5 hydroxyindoleacetic acid (5HIAA) and many others found in blood samples, or in the tumor tissue . Beside the circulating biomarkers, imaging biomarkers plays a central role in diagnosis, staging, treatment selection and follow-up of NETs . Current imaging tools are morphological modalities such as CT, MRI and Ultrasound and molecular imaging. Several types of molecular imaging techniques are performed to characterize NETs: single photon emission computed tomography (SPECT) with 111In-pentetreotide, largely superseded now by positron emission tomography (PET) with 68Ga-labeled somatostatin analogs, is used to identify the somatostatin receptor status.

The Feasibility of Novel 124I-MIBG Tracer in Evaluation of Myocardial Sympathetic Denervation and Assessment of Neuroendocrine tumors. Comparison with 123I-MIBG.

The primary objective of this study is to analyse the concentration dopamine and serotonin in thrombocytes of patients with renal cell carcinoma and neuro-endocrine tumours compared to the concentrations of these catecholamines in healthy volunteers. The concentration dopamine and serotonin in thrombocytes with and without medication will also be evaluated.
