Filter by:Nutritional status in patients with neuroendocrine tumours (NETs), especially of gastroenteropancreatic origin, can be deeply affected by excessive production of gastrointestinal hormones, peptides, and amines, which can lead to malabsorption, diarrhoea, steatorrhea, and altered gastrointestinal motility. Besides, the surgical and/or medical management of NETs can lead to alteration of gastrointestinal secretory, motor, and absorptive functions, with both dietary and nutritional consequences. Indeed, disease-related malnutrition is a frequently encountered yet both underrecognized and understudied clinical phenomenon in patients with NETs, with substantial prognostic and socioeconomic consequences. Most of these conditions can be alleviated by a tailored nutritional approach, also with the aim of improving the efficacy of cancer treatments. In this setting, skilled nutritionists can play a fundamental role in the multidisciplinary health care team in NETs management and their presence should be recommended.
Neuroendocrine tumors of the lung include the small cell carcinoma (SCLC), and large cell neuroendocrine carcinoma (LCNEC) and represent 20% of lung cancer. One of the only studies reported to date is reporting on a progression-free survival (PFS) and overall survival (OS) of 5.2 months and 7.7 months, respectively. Poorly differentiated gastroentero-pancreatic neuroendocrine carcinomas (GEP-NEC) represent a small sub-group of digestive NENs, according to the studies, 7 to 21% of patients. However, their prognosis is more negative, with the 5-year survival at less than 20%. Many Phase III trials showed superiority in terms of efficacy and tolerance of nivolumab+/-ipilimumab versus standard chemotherapy in second-line treatment in metastatic solid tumors. Neuroendocrine tumors are considered as rare disease without therapeutic guidelines in this setting. The French academic oncology groups (IFCT, FFCD and GERCOR) have the opportunity to recruit a sufficient number of patients, in a reasonable period of time, to provide a proof-of-concept of the safety and efficacy of nivolumab+/-ipilimumab in this population.
The objective is to investigate the impact of intra-arterial administration of 177Lu-dotatate on the intrahepatic biodistribution in patients with NET liver metastases. Our primary objective is to evaluate if there is a difference in post-treatment tumor-to-non-tumor (T/N) activity concentration ratio on SPECT/CT between the intra-arterial treated liver lobe and the intravenous treated liver lobe.
Neuroendocrine tumours (NETs) are generally slow growing, but some can be aggressive and resistant to treatment. Compared to healthy cells, the surface of these tumor cells has a greater number of special molecules called somatostatin receptors (SSTR). Somatostatin receptor scintigraphy and conventional imaging are used to detect NETs. This study proposes 68Gallium(68Ga)-DOTATOC positron emission tomography/computed tomography (PET/CT) is superior to current imaging techniques. The goal is to evaluate the safety and sensitivity of 68Ga-DOTATOC PET/CT at detecting NETs and other tumors with over-expression of somatostatin receptors.
This phase Ib trial studies how well pembrolizumab works with combination chemotherapy in treating participants with small cell/neuroendocrine cancers of the urothelium or prostate that has spread to nearby tissue or lymph nodes or that has spread to other places in the body. Monoclonal antibodies, such as pembrolizumab, may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as etoposide, docetaxel, cisplatin, and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving pembrolizumab with platinum-based chemotherapy may work better in treating participants with small cell/neuroendocrine cancers of the urothelium or prostate.
Neuroendocrine tumors (NET) are a network of rare tumors with common embryological origin. Functional imaging plays a major role in the extension assessment and tumor characterization of NETs. SPECT/CT with 111In-pentetreotide is the recommended test when tumors are well differentiated (grade G1 or G2). It has a real interest in diagnosis, in therapeutic decision-making (in particular by cold somatostatin analogues or in PRRT) and in the systematic follow-up of patients. Nevertheless, SPECT/CT procedure makes for a relatively long review. In addition, scintigraphy has a lower spatial resolution than PET technology and remains of limited interest for signal quantification. However, the ability to locate and quantitatively measure the absorption of radiopharmaceuticals in the target tissues is a major challenge in oncology for the characterization of the disease. Recent developments in radiopharmacy have made it possible to target NETs in PET imaging through the use of somatostatin analogues coupled with positron emitters, called 68Ga-DOTA peptides. The diagnostic performance of 68Ga-DOTApeptide PET/CT appears to be superior to SPECT/CT with 111In-pentetreotide. A marketing authorization has thus recently been issued in France for the use of 68Ga-DOTATOC. Historically, the recommended quantification method in PET was based on the instantaneous measurement in static acquisition (3D) of the maximum of the standardized uptake value (SUVmax). This approach has the disadvantage to measure the signal at a time "t" for a single voxel of the image. Dynamic acquisition methods (4D) have been proposed to extract a radiotracer absorption coefficient (Ki) for a lesion. Several studies have demonstrated the superiority of Ki versus SUVmax in 18FDG PET/CT for the diagnostic management, therapeutic evaluation and prognosis of various solid cancers. However, no work has validated this approach in PET / CT at 68Ga-DOTATOC as part of the prognostic evaluation of NETs. The objective of the study is to evaluate the prognostic value of the tumor absorption coefficient Ki resulting from a 4D whole-body dynamic acquisition in PET / CT at 68Ga-DOTATOC in patients with well-differentiated NETs grade I or II according to the WHO classification
The purpose of the study is to evaluate, in standard practice, the change in information received and perceived by the patient, extension of the disease and its treatment. These parameters will be evaluated by means of validated self-administered questionnaires that can be used in standard practice.
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).
Carcinoid Heart Disease (CHD) is a rare form of heart disease, occurring in over 50% of the patients with carcinoid syndrome. Pathophysiology, prognostic factors of development of Carcinoid Heart Disease and progression of disease remain unclear. This observational multicenter cohort study is designed to study the occurrence of Carcinoid Heart Disease in patients with differentiated carcinoid tumors, to describe numerous factors influencing the occurrence, severity, progression and long-term survival of patients with Carcinoid Heart Disease. Basic informations and detailed diagnosis informations (oncological and cardiac parameters), are collected by professional doctors. Clinical outcomes (onset of Carcinoid Heart Disease, cardiac surgery, related death) will be followed up every year or every six/three months if clinically indicated.
This is a prospective study to investigate the long-lasting radiolabeled somatostatin analogue based peptide receptor radionuclide therapy and evaluate response to 177Lu-DOTA-EB-TATE in patients with advanced metastatic neuroendocrine tumors. Different groups with doses of 0.37GBq-0.74GBq (10-20 mCi) and 1.85GBq (50 mCi)of 177Lu-DOTA-EB-TATE, 3.7GBq (100 mCi)of 177Lu-DOTA-TATE will be injected intravenously. Besides, we evaluated the safety and dosimetry of 3.7GBq (100 mCi) of 177Lu-DOTA-EB-TATE with and without amino acid infusion. All patients will undergo 68Ga-DOTATATE PET/CT scans before and after the treatment.
