Active clinical trials for "Neuroendocrine Tumors"

This is a safety study to determine the phase 1 starting dose of [90]Yttrium-DOTATOC when it is administered intravenously for patients with neuroendocrine tumors that have spread to the liver.

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.

With so many therapeutic options available (i.e.: biologic therapy, liver directed therapy, radiotherapy and chemotherapy), the purpose of this project is to partner with patients on comparative effectiveness research (CER) to achieve the goal of alleviating undue toxicity, and optimizing effectiveness and sequencing of therapy for neuroendocrine tumors (NET) patients. We will conduct a study of all newly occurring GEP-NET and lung NET cases aged 18 years and older diagnosed between 01/01/2018 through 12/31/2023 across 14 sites participating in the National Patient-Centered Clinical Research Network (PCORnet), enrolling an average of 215 patients per site over the 3 year study period (~3,000 patients total), allowing up to 60 months of follow-up for medical record outcomes. Participants will complete four online or paper surveys over 18 months; these surveys will focus on patient-reported outcomes, including questions on quality of life, treatment decisions, and experiences with cancer care. Survey data will be linked to participant medical record data to achieve study aims.

This study is a multicenter observational study with a central registration system and all-case surveillance system without a control group.

Digestive NETs are the second most common malignant digestive tumor after adenocarcinoma. The most common gastrointestinal NETs arise from the small intestine. These tumors have a high lymph node and distant metastatic potential (hepatic, pulmonary, etc.). Their management is essentially surgical and the extent of the resection essentially depends on preoperative data from conventional and isotopic imaging. The goal of surgical resection is to remove the portion of the small intestine carrying the tumour(s) with healthy margins (so-called R0 resection) and affected lymph nodes in the mesentery (lymph node dissection). The extent of lymph node dissection, sometimes significant, exposes you to the risk of short hail with its own complications (malnutrition, diarrhoea, etc.). Consequently, an analysis of the benefits and risks between the interest of an extensive and oncological resection (R0) and the risks of short bowel must be carried out for each patient. The reference examination to define lymph node involvement is determined by the histological examination of the resected surgical specimen (reference examination). The preoperative evaluation of lymph node extension is done by preoperative abdominal CT scan. However, the preoperative CT scan is not always consistent (sensitivity and specificity) with the pathology data (reference examination). For about 5 years, isotopic imaging (DOPA-PET and DOTATOC) has become feasible and could improve the quality of preoperative evaluation of lymph node extension. Consequently, the aim of this study is to determine the contribution of isotopic imaging (DOPA-PET and DOTATOC) in the preoperative evaluation of lymph node extension.

Objectives: The aim of the present study is to assess the significance of metabolomics and genetics in diagnosing and survival evaluation for pNET in the periodic follow-up of MEN1 patients. Aim 1: To evaluate the relationship of serum global metabolic profiles with subsequent development of aggressive PNET and evaluate patients survival in a nested case-control study of MEN1 patients who have developed aggressive PNETs (cases) and MEN1 patients who have developed non-aggressive PNETs (controls). Aim 2: Validate the top serum metabolites identified from Aim 1 in MEN1 patients who have developed aggressive PNETs and MEN1 patients who have developed non-aggressive PNETs, using a targeted metabolomics approach. Aim 3: Prospectively identify the potential miRNA biomarkers of serum with miRNA sequencing in MEN1 patients who have developed aggressive PNETs (cases) and MEN1 patients who have developed non-aggressive PNETs (controls). Aim 4: Validate the potential miRNA biomarkers identified from Aim 1 in MEN1 patients who have developed aggressive PNETs and in MEN1 patients who have developed non-aggressive PNETs, using a targeted qRT-PCR approach (in serums), as well as to see the relationship of potential miRNA biomarkers with patients survival.

Quantitative parameters obtained with dynamic whole body imaging using positron emission tomography (PET) can provide additional and complementary information to standard PET. Dynamic imaging allows for better understanding of the behavior of the radio-pharmaceutical because it can be followed over time. Thought to be difficult to perform with currently available clinical equipment that can affect the clinical workflow, it has recently shown to be feasible. We want to test the feasibility of this imaging technique and evaluate its utility in identifying lesions with three different radio-pharmaceuticals as compared to standard static PET. This study will also determine the clinical impact of DWB PET on participant management by comparing the overall qualitative assessment performed by nuclear medicine physicians between the standard PET images and the DWB ones.

It is well known that the prevalence of malnutrition or risk of malnutrition in cancer patients is high, as well as its impact on different parameters such as hospitalization, survival or response to certain treatments. In patients with gastroenteropancreatic (GEP) neuroendocrine tumors (NET), due to their heterogeneity and longer survival, it is expected that the prevalence of malnutrition is probably underdiagnosed, as well as the existence of a negative impact on different parameters (quality of life, survival). So far, the studies carried out on nutrition and NET are very scarce and none has been carried out so far in Spain. Before being able to carry out nutritional intervention studies on these patients, it is necessary to know the reality of the nutritional status of patients with NETs in Spain. The main motivation for the NUTRIGETNE study is to evaluate the epidemiological status of nutrition in NETs in the spanish population. In addition to know the epidemiological picture, it is intended to study the nutritional status from different points of view: analytical, clinical, anthropometric, etc. Besides, the study of nutritional status will allow us to closely monitor the patients who have a higher risk of malnutrition and to propose early interventions for those, as well as the impact of their nutritional status on different parameters: survival, hospitalization, quality of life or responses to the treatments. NUTRIGETNE is a cross-sectional, open and multicenter study in which the nutritional status of patients with GEP NET in Spain will be evaluated.

Observational trial to assess the feasibility of monitoring patient reporting symptoms via mobile devices

The indications for synchronous liver resection for metastatic neuroendocrine tumors of pancreatic origin remain debated and poorly described in the literature. The reported mortality of this type of simultaneous resection remains very high, especially when a cephalic duodenopancreatectomy is associated with a hepatic resection (up to 40%). The benefit in terms of survival remains to be evaluated. The ReSiPaTNE study proposes to create a retrospective cohort of simultaneous pancreatic and hepatic resections for metastatic neuroendocrine tumors in order to evaluate the short and long term results of this type of resection. The evaluation of the results of this type of resection may be useful for the selection of patients for treatment.
