Active clinical trials for "Bile Duct Neoplasms"

The implementation of liquid biopsy in clinical practice has been favored by the rapid development of genome sequencing techniques designed to analyze mutations in ctDNA. Among these, the Next generation sequencing (NGS) is a technique that consists in sequencing several genomes in a short time span, collecting information about a wider range of genomic alterations, using small quantities of genetic material. It is used to identify potential circulating dynamic biomarkers of treatment sensitivity or resistance in a real word multi-pathology evaluation. In this way, defining the mutational status of clinical relevance genes in real world, as a predictive biomarker to identify those patients most likely to benefit from target therapy, offers the potential to optimize access to further therapies. The aim of this study is to evaluate the real-world prevalence of clinically useful mutations in patients who are receiving therapy for advanced and locally advanced solid tumor through liquid biopsy.

This is the prospective observational study to explore whether the SpyGlass DS II system could be used to screen early-stage neoplastic bile duct lesions in selected patients.

The goal of this observational cohort study is to assess the yield of preoperative endoscopic ultrasound focussed on lymph nodes in patients with presumed resectable perihilar (pCCA), intrahepatic (iCCA) or mid-common bile duct (CBD) cholangiocarcinoma. The main questions it aims to answer is: The number of patients precluded from surgical work-up due to positive regional or extraregional lymph nodes identified by endoscopic ultrasound guided tissue acquisition Characteristics during endoscopic ultrasound of lymph nodes associated with malignancy

This pilot clinical trial studies copper Cu 64 anti-carcinoembryonic antigen (CEA) monoclonal antibody M5A positron emission tomography (PET) in diagnosing patients with CEA positive cancer. Diagnostic procedures, such as copper Cu 64 anti-CEA monoclonal antibody M5A PET, may help find and diagnose CEA positive cancer that may not be detected by standard diagnostic methods.

This clinical trial studies positron emission tomography (PET)-computed tomography (CT) in determining the radiation dose delivered with radioactive spheres to patients with liver metastasis or primary liver or biliary cancer. Comparing results of diagnostic procedures dose before and after delivery of radioactive spheres to the liver may help determine radioembolization dose and plan the best treatment for liver metastasis or primary liver or biliary cancer.

The purpose of this study is to evaluate the safety, tolerability, and immune response of different doses of URLC10 peptide emulsified with Montanide ISA51 in combination with gemcitabine. Recommended phase II dose will be also determined.

Digital single-operator cholangioscopy (DSOC) has emerged as a medical advance with an important role in the evaluation of indeterminate biliary lesions. This technique has demonstrated higher sensitivity in the guidance for tissue acquisition when compared with standard endoscopic retrograde cholangiopancreatography (ERCP). DSOC-guided biopsy is considered technically safe and successful for tissue collection. Hand in hand with the development of more precise diagnostic techniques, comes the implementation of artificial intelligence (AI) for diagnostic assessment. For the past decade, the role of artificial intelligence (AI) has been increasing at a rapid pace. In the biliary tract, different models have been proposed for the characterization of malignant features. Nevertheless, to date, the discrepancy between the visual impression of the operator and the histological results obtained by cholangioscopy still present, affecting the accuracy the diagnosis. Based on the above, the investigators aim to assess the diagnostic accuracy of AI for the guidance of tissue acquisition with DSOC compared to DSOC without AI for suspected cholangiocarcinoma. As a secondary aim, the investigators pursue to compare quality of AI-guided biopsies samples vs. DSOC biopsies without AI.

The project aims at analysing prognostic and predictive factors involved in diagnostics and surgical treatment of cysts and tumors in the pancreas and periampullary region using both clinical data and blood and tissue samples for biomarker development and validation.

The iCaRe2 is a multi-institutional resource created and maintained by the Fred & Pamela Buffett Cancer Center to collect and manage standardized, multi-dimensional, longitudinal data and biospecimens on consented adult cancer patients, high-risk individuals, and normal controls. The distinct characteristic of the iCaRe2 is its geographical coverage, with a significant percentage of small and rural hospitals and cancer centers. The iCaRe2 advances comprehensive studies of risk factors of cancer development and progression and enables the design of novel strategies for prevention, screening, early detection and personalized treatment of cancer. Centers with expertise in cancer epidemiology, genetics, biology, early detection, and patient care can collaborate by using the iCaRe2 as a platform for cohort and population studies.

Observational study that will be collecting clinical and molecular health information from cancer patients who have received comprehensive genomic profiling and meet the specific eligibility criteria outlined for each cohort with the goal of conducting research to advance cancer care and create a dataset that furthers cancer research.
