Active clinical trials for "Pancreatic Neoplasms"

This is a retrospective observational study to determine the proportion of patients with a family history of pancreatic cancer and other malignancies among patients who have intraductal papillary mucinous neoplasm (IPMN). The investigators will be reviewing the demographic, clinical, radiologic, pathologic, and follow-up information from the Pancres Center database. The investigators will also conduct a chart review to collect information recorded by clinicians on each subject's family history of malignancy and personal history of malignancy. Results of this database and chart review will be incorporated into a datasheet in which all patient identifiers have been removed. The primary outcome will be the percentage of IPMN patients with at least one first-degree relative with pancreatic cancer or IPMN, or at least two first or second degree relatives with pancreatic cancer, IPMN, or malignancies related to pancreatic cancer syndromes, including colorectal, gastric, breast, ovarian, and melanoma neoplasms. Secondary outcomes will be the relative risk of IPMN subtypes of higher malignant potential (main duct or mixed type location), more advanced histology (carcinoma in situ or invasive carcinoma), and recurrence following surgical resection amongst subjects with a family history.

Extracapsular lymph node involvement (ECLNI) has been identified as a pathological variable associated with worse outcome in esophageal, gastric and colorectal cancer. No studies so far have studied its prognostic impact in ductal pancreatic adenocarcinoma (DPAC). The goal of the investigators is to determine the prognostic value of ECLNI in a prospective consecutive series of 145 patients with DPAC, who underwent resection of their primary tumor between 1998 and 2005.

The investigators hypothesize that the CXCR2 ligands/CXCR2 biological axis plays an important role in promoting angiogenesis in PC; and that the genetic changes and the microenvironment of the tumor regulate the expression of CXCR2 ligands/CXCR2 in PC in order to potentiate their angiogenic phenotype. A corollary of this hypothesis is that the cell surface receptors (CXCR2) and the intracellular signaling pathways that mediate the angiogenic responses induced by ELR+ CXC-chemokines are potential targets for novel therapeutic interventions in PC.

Chart Review of patients with pancreatic cancer treated with combination of irinotecan, oxaliplatin and cetuximab.

To prospectively collect serum and DNA samples from subjects with pancreatic cancer, pancreatitis, liver disease, and from healthy and at-risk volunteers in order to identify novel biomarkers for early diagnosis, differential diagnosis, stage, natural history of the disease, response to treatment, and to identify novel targets for therapeutic interventions. In particular:

Pancreatic cancer (PC) is recognized as one of the most challenging tumors to deal with and it is still characterized by a poor long-term prognosis. However, treatment of PC in high-volume centers with the support of a multidisciplinary approach has widely demonstrated improvement both in terms of short- and long-term outcomes. The recent worldwide spread of Covid-19 pandemic significantly affected the healthcare systems of most countries in the world, particularly in red areas such as Italy, with more than 100.000 cases in a two-month time lapse. This inevitably reflected in a reorganization of hospital activities, including the diagnostic and therapeutic pathways for PC treatment. With the aim of giving an objective and real representation of the impact of Covid-19 on PC treatment, the investigator here propose a multicenter Italian observational study comparing a 6-month period before and during the Covid-19 pandemic. Only high-volume centers will be involved in the study. A comparison between the general, clinical, endoscopic and surgical outcomes will be performed by means of a global and month-by-month analysis between the two study periods.

An international, multicenter study to identify tumor molecular particularities and neoepitopes among participants with colorectal and pancreatic tumors undergoing surgery.

Vascular pattern of solid pancreatic lesions (SPLs) has been investigated by different abdominal imaging modalities and by contrast-enhanced endoscopic ultrasonography (CE-EUS). Compared with surrounding pancreatic parenchyma three different patterns have been described: hypo-, iso-, and hypervascular. The majority of SPLs are hypovascular, and the diagnostic relevance of hypoenhanced pattern to predict pancreatic adenocarcinoma (PDAC) is well established. Differently, iso- and hypervascular pattern is not specific and can be expressed by several SPLs, with different clinical behavior and management. To date, poor is know about the role of EUS in differential diagnosis of non-hypovascular SPLs and features associated with malignancy.

This is a prospective population based study to examine the relationship of oral and pancreatic microbiome, and their functions, to pancreatic cancer risk. The identification of specific oral bacteria and their functional relationship to pancreatic cancer will advance scientific knowledge on the etiology of pancreatic cancer. This could provide a new microbially-based research paradigm, possibly leading to new drug targets for this disease. Second, the oral bacteria may serve as a readily accessible, non-invasive biomarker for subsequent pancreatic cancer risk, which help to identify people at high risk of this disease. Finally, the identified oral bacteria may lead to microbial prophylactic preventions, with antibiotic therapy aimed at eradicating the specific species associated with increased cancer risk or, alternatively, combined with probiotics to introduce species that are associated with a decreased cancer risk. Thus, the study outcomes will lead to actionable means for pancreatic cancer prevention.

The WhippleBenchmark 2 Collaborative study aims at defining benchmark criteria for best achievable outcomes after pancreaticoduodenectomy with portal vein resection.
