Active clinical trials for "Cholangiocarcinoma"

This study is a biobank of specimens and clinical data for use in current and future research to better understand the cholestatic liver diseases primary biliary cirrhosis/cholangitis (PBC) and primary sclerosing cholangitis (PSC).

The goal of this evaluate short, medium and long term outcome of the different embolization techniques in patients with primary and secondary hepatic tumors. The main aim is to evaluate progression free survival following embolization in this study population or evaluate residual hepatic volume in cases in which these techniques are used to induce liver regeneration. This study is an observational registry - all patients will follow their normal therapeutic and treatment scheme as per clinical practice, without any additional intervention.

The purpose of this research is to create a collection of bile, bile duct brushings and medical information from people with Primary Sclerosing Cholangitis (PSC) and controls to learn more about changes that occur in the liver.

The purpose of this study is to develop and validate a radiological nomogram including radiological characteristics, clinical risk factors, and medical history. And we aim to establish a noninvasive method for the diagnosis of intrahepatic cholangiocarcinoma (ICC), and to construct a differential diagnosis model for ICC and hepatocellular carcinoma (HCC) with higher sensitivity and accuracy.

The Percutaneous Cholangiopancreatoscopy (PCPS) registry is an observational, multicentric, prospective, and retrospective registry of patients undergoing the percutaneous cholangiopancreatoscopy procedure at sites across the United States. In the retrospective component of the study, clinical and procedural data regarding patients who have undergone clinical indicated percutaneous cholangiopancreatoscopy procedure in the past will be collected from all the registry sites and stored in a secure database. The prospective component of the registry will run for three years at each site where patients undergoing the clinically indicated percutaneous cholangiopancreatoscopy procedure will be enrolled in the study, and the patients' data will be collected whenever the patients present to interventional radiology (IR) for a procedure or clinic visit.

This is a single-center, prospective, observational and exploratory clinical study. The object of this study is to evaluate the accuracy of proteomics approaches on resected lymph node samples in evaluating lymph node metastasis status in cholangiocarcinoma patients.

Choledochal cysts are congenital cystic dilatations of the intra and/or extrahepatic bile duct. They have been considered a rare entity of the child population. Globally, they account for 1% of all biliary pathology benign, with a clearly higher incidence in Asian countries (1/5,000 in China, 1/1,000 in Japan, compared to 1/100,000-150,000 in Western countries). However, the number of adults diagnosed in recent years has increased by up to 70% due to improvements in imaging tests. Currently, the common bile duct malformation is considered a premalignant entity: although the data are not very precise, it is estimated that between 2.6% and 26% of patients diagnosed choledochal cyst, will develop cholangiocarcinoma. In this sense, we must bear in mind that most of the published literature is of Asian origin, where the rate of cholangiocarcinoma is 0.1-71/100,000 compared to 0.1-1.8/100,000 in Europe or 0.6-1/100,000 in the USA. The most used classification to differentiate the types of cysts is that of Todani. Following this classification, we would find a higher rate of malignancy on types I and IV. The recommendations found in the literature refer to the need for surgical intervention for choledochal cysts due to their high rate of malignancy. These recommendations are based on studies conducted in a symptomatic Asian population. We do not usually find in therapeutic algorithms the inclusion of various factors that could be involved in the development of malignancy such as episodes of cholangitis, presence of anomaly in the pancreatobiliary junction, presence of lithiasis in cystic dilatation, etc. Some surveys carried out among the scientific population reflect a lack of consensus on its management: in the same clinical situation, different surgery units specialized in hepatobiliary-pancreatic pathology would act in the opposite way (specifically surgical versus conservative treatment). Bile duct resection is not without complications, both short-term and long-term. Therefore, the patient's symptoms, age or comorbidities can play an important role in decision-making in the treatment of this pathology. This nationwide multicenter retrospective observational study aims to determine the clinical situation of this rare pathology in a Western environment. A retrospective analysis of patients diagnosed with choledochal cyst in the period between 2000 and 2020 is proposed. Demographic variables, risk factors for cholangiocarcinoma, symptoms associated with the cyst and its characteristics, diagnostic method, type of treatment, complications will be analyzed. Malignancy, time, and follow-up method will also be discussed. This study will attempt to answer questions about the incidence of choledochal cysts in our environment, their association with cholangiocarcinoma, the associated morbidity and mortality, as well as the therapeutic and follow-up attitudes adopted in the face of this rare pathology.

In this study, the investigators aim to demonstration of relationship between triceps skinfold thickness and overall survival of pancreatic cancer, cholangiocarcinoma and GB cancer.

Background: Primary Liver Cancer is the second most common cause of cancer-related death worldwide. It is the cancer with the fastest rising incidence and mortality in the United States. Researchers want to learn more about liver cancer to help them design better treatments. Objective: To better understand liver cancer. Eligibility: People ages 18 and older who have liver cancer and had or are planning to have immune therapy Design: Participants will be screened with a review of their medical records. They will be asked about their medical history and test results. Participants will come to the NIH Clinical Center. During this visit, their medical records, test results, imaging studies, and tissue samples (if available) will be gathered. Participants will learn the results of a test to see if they have any mutations known to be connected to cancer. They will learn if there are treatment options for them. Participants will give blood, urine, and stool samples or rectal swabs. Participants will not have follow-up visits just for this study. If they join another NIH research study and have visits for this other study, their medical records; test results; and blood, urine, and stool samples may be collected. This will occur about every 3 months. If they have a biopsy or surgery on another study or as part of treatment and there is leftover tissue, researchers would like to collect some of that tissue. Participants will be contacted every 6 months by phone or e-mail. They will be asked about their health. They will provide any medical records, test results, and imaging studies. Participants will be followed on this study for life.

This research will have a significant impact on the overall management of those cancer patients and their family members who are at risk for hereditary cancer due to germline inactivation of BAP1. Our study will ultimately facilitate the development of novel screening, prevention and treatment strategies for these individuals with the syndrome. Because the vast majority of UM develop in pre-existing nevi, characterization of individuals at high risk for development of UM will allow closer screening and earlier intervention which would improve the treatment outcome not only for retaining vision but also for overall survival. Similarly in patients with germline BAP1 mutation CM develops in premalignant atypical melanocytic lesions and careful follow up of these patients will improve the outcome of their disease. In addition this study could have impact on the management of patients with personal and/or family history of several other cancers reported in patients with germline BAP1 mutation such as mesothelioma, renal cell carcinoma, cholangiocarcinoma, hepatocellular carcinoma, meningioma and basal cell carcinoma.
