Active clinical trials for "Gallbladder Neoplasms"

Biliary tract cancer is a rare gastrointestinal malignant neoplasm and includes intrahepatic cholangiocarcinoma, extrahepatic cholangiocarcinoma, and gall bladder cancer. Curative surgical resection offers the only chance for cure. However, most patients with BTC are diagnosed at an unresectable stage. Therefore, the survival outcomes of patients with advanced biliary tract cancer remain dismal. The combination of gemcitabine and cisplatin has become the current standard for advanced BTCs since the landmark ABC-02 trial in 2010. However, the median overall survival of Gem/Cis chemotherapy is less than 1 year. Recently, a triplet regimen of gemcitabine, cisplatin, and nab-paclitaxel showed promising results in a single-arm phase II multicenter study. However, biliary tract cancer is a group of heterogenous diseases by site and genetic alteration, and this diversity may lead differences in response to systemic chemotherapy. Transcriptome analysis through RNA-sequencing has rarely been performed in advanced biliary tract cancer, and even if it has performed, only small number of patients were included. Further research on multi-omics data is needed on the necessity and clinical significance in treatment of biliary tract cancer.

Hepatobiliary tumors have a poor prognosis and high individual heterogeneity, so it is of great significance to find important prognostic markers and then screen out specific subgroups of people; meanwhile, chronic hepatitis, cirrhosis, and healthy control participants also need to show the evolution of tumors and discover specific diagnostic markers as a control group. Moreover, targeted therapy and immunotherapy make cancer treatment enter a new field, but only part of patients achieve response rates and reach clinical benefit. However, these drugs are expensive and can cause treatment-related adverse events. Therefore, reliable biomarkers identification is needed to help predict the response to these treatment options in order to screen patients with better responsiveness and avoid wasting money. Multi-omics research can reveal the characteristics of hepatobiliary tumors more deeply and find meaningful therapeutic targets. Therefore, 450 patients at least 18 years of age with hepatobiliary tumors were included in this study.

The PLATON Network study is designed to elevate personalized therapy based on genomic tumor profiles in gastrointestinal cancer patients. Hereby, PLATON's study-design focuses on the patient's tumor molecular profiling. Within the network a web application will be developed to link clinical investigators and information on study sites, cancer patients and genetic alteration data, as well as available clinical trials at PLATON's study sites.

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.

Hepatobiliary tumors have a poor prognosis and high individual heterogeneity, the patient with hepatobiliary tumors even accepted radical surgery, the postoperative recurrence rate is still high. Therefore, it is of great significance to find important prognostic markers to improve patient prognosis and formulate new treatment plans. In recent years, targeted therapy and immunotherapy make cancer treatment enter a new field, However, tumor heterogeneity is the greatest challenge in cancer therapeutics and biomarkers discovery. In this study, we collected a wide rang of patients' information, including photos of patients' face, physical strength and nutrition indicators, blood ,stool and pathological tissue specimens from tumor patients, then Multi-omics testing were applied to Looking for novel therapeutic targets and prognostic markers to predict patient response to treatment. Clinicians choose the best treatment plan for the patient based on the test results to improve the patient's survival time and quality of life.

The gallbladder is the most common primary cancer site among the biliary tracts and its incidence is increasing. Its prognosis is still poor with a 5-year survival of almost 20%. Cholecystectomy is curative in patients with Tis and T1a. For patients with resectable T1b and above disease, radical cholecystectomy is advocated consisting of en bloc resection of the gallbladder, wedge resection of the liver or segment 4b, extrahepatic bile duct, and the regional lymph nodes. The aim of this study is to compare patients who have undergone Robotic, Laparoscopic and Open liver resection with lymphadenectomy for >T1b gallbladder cancers in a case-matched analysis using propensity scores. The primary endpoints are intra- and postoperative outcomes, and the secondary endpoints long-term oncologic outcomes and feasibility and adequacy of minimally invasive versus traditional open approach.

Based on the cell free nucleic acid analysis information of blood samples, the results of microbiome and metabolite analysis of stool and urine samples of pancreatic cancer and bile duct cancer patients, the clinical correlations of them with primary cancer are evaluated. And based on these information, biomarkers for diagnosis, treatment, and prognosis of pancreatic and bile duct cancer are explored.

Chromosomal instability (CIN) refers to ongoing chromosome segregation errors throughout consecutive cell divisions. CIN is a hallmark of human cancer, and it is associated with poor prognosis, metastasis, and therapeutic resistance. Analyzing CIN of the DNA extracted from bile tract exfoliated cells in bile samples seems a promising method for diagnosing, monitoring, and predicting the prognosis of patients with malignant biliary obstruction, including biliary tract cancer (BTC), pancreatic head carcinoma. CIN can be assessed using experimental techniques such as bulk DNA sequencing, fluorescence in situ hybridization (FISH), or conventional karyotyping. However, these techniques are either time-consuming or non-specific. The investigators here intend to study whether a new method named Ultrasensitive Chromosomal Aneuploidy Detection (UCAD), which is based on low-coverage whole-genome sequencing, can be used to analyze CIN thus helping diagnose malignant biliary obstruction and assessing follow-up.

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.

The goal of this observational study is to learn about deep learning radiogenomics for individualized therapy in unresectable gallbladder cancer. The main questions it aims to answer are: (i) whether a deep learning radiomics (DLR) model can be used for identification of HER2status and prediction of response to anti-HER2 directed therapy in unresectable GBC. (ii) validation of the deep learning radiomics (DLR) model for identification of HER2 status and prediction of response to anti-HER2 directed therapy in unresectable GBC. Participants will be asked to Undergo biopsy of the gallbladder mass after a baseline CT scan Based on the results of the biopsy, patients will be given chemotherapy either targeted (if Her2 positive) or non-targeted Response to treatment will be assessed with a CT scan at 12 weeks of chemotherapy
