Active clinical trials for "Pancreatic Neoplasms"

Bio-repository to collect bio-specimens from patients with 1) pancreatic cysts and 2) patients at high risk, defined by family history and/or genetic mutations, for pancreatic cancer.

The NFPTR was established in 1994 to find the causes of pancreatic cancer. In brief, the investigators are interested in both the genetic and non-genetic causes of pancreatic cancer. The investigators are particularly interested in finding the genes that cause pancreatic cancer to cluster in some families. Up to 10% of pancreatic cancer patients have another close relative who has also developed pancreatic cancer. This clustering of pancreatic cancers in families has yet to be explained; however, the investigators continue to identify new familial pancreatic cancer genes that explain this clustering in subsets of families. For example, in 2009 and 2012 the investigators discovered that mutations in the PALB2 and ATM genes jointly account up to 5% of the clustering of pancreatic cancer in families.

The purpose of this study is to isolate and analyze exosomes, which are tiny carriers of important proteins and nucleic acids that serve as messenger systems in the blood and tissue. Blood and tissue from patients with pancreatic cancer will be compared with blood and tissue from patients with noncancerous pancreatic disease. Including patients without cancer will allow the investigators to establish "normal" values, which currently do not exist. The investigators will then look to see whether exosome activity has a connection to disease recurrence and outcomes in patients. The results of this study will be the basis for future studies exploring this area.

Identifying biomarkers of early pancreatic ductal adenocarcinoma (PDAC) could facilitate screening for individuals at higher than average risk and expedite the diagnosis in individuals with symptoms and substantially improve an individual's chance of surviving the disease. The investigators propose a longitudinal study of subjects at higher than average risk of PDAC in order to generate clinical data and bank serial blood specimens.

This is an observational, biospecimen collection protocol to develop a bank of pancreatic cancer tissue and normal tissue.

IRFARPC is a multicenter national registry designed to study the diagnosis and predisposing factors of subjects with an inherited increased risk for pancreatic cancer.

Microbiome in patients affected by pancreatic ductal adenocarcinoma may present specific and identifiable patterns. These variations could affect the surgical outcome and increase the risk of life-threatening infections supported by multidrug-resistant bacteria. The identification of microbial signatures with tumor specificity may have a potential role in postoperative risk stratification. Variation of pancreatic, intestinal or bile microbiome and their relationship can be investigated and measured as promising tools in order to predict and overcome the clinical and infectious burden imposed by MDR infections. The prospect of a potential role for probiotics to promote competition against the pathogens and to improve the gastrointestinal barrier integrity has also been raised. Moreover, if the bacterial composition in human PDAC was confirmed to be distinct from that of the normal pancreas, microbiome variation could be used as a potential biomarker, to assess the potential for malignancy in precursor neoplastic lesions. However, we believe that a preliminary and explorative study is necessary. The study aims to outline the pancreatic microbiome of patients who undergo upfront PD for resectable PDAC and to characterize the possible association between bacterial composition and the occurrence of post-operative complications, particularly POPF and IC.

Multi-centre Retrospective Observational Cohort study of patients who underwent pancreaticoduodenectomy from 01/01/2005 to 01/02/2022 with histologically confirmed pancreatic head malignancy

Pancreatic cancer is one of the most fatal malignancies with a 5-year survival rate of only ~6%[1]. The reasons for this high mortality rate can be attributed to several factors, of which perhaps the most important is delayed diagnosis due to vague symptoms and consequently missed opportunities for surgical resection. Therefore, the ability to detect pancreatic cancer at an early, more curable stage is urgently needed. Identifying risk factors and biomarkers of early pancreatic cancer could facilitate screening for individuals at higher than average risk and expedite the diagnosis in individuals with symptoms and substantially improve an individual's chance of surviving the disease. Thus, the investigators propose this longitudinal study entitled, "Artificial Intelligence-based Early Screening of Pancreatic Cancer and High Risk Tracing (ESPRIT-AI)" in order to generate clinical data sets and bank serial blood specimens of high risk individuals.

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.
