Active clinical trials for "Biliary Tract 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.

Define the circRNA expression profile in PDAC and identify dysregulated circRNA candidates. These will be validated in further tissue samples. Evaluate candidate circRNA Expression in blood (plasma samples) as a clinically relevant diagnostic biomarker; expanding on the primary objective to include other diagnostic features such as specificity, area under the receiver operator curve, positive predictive value and negative predictive value. Explore the expression of candidate circRNAs and related molecules in patient biomaterials (including tissue, blood, bile and biopsy samples) as biomarkers for diagnosis; prognostication; association with clinico-pathologic features and survival outcomes; and their ability to predict/monitor treatment response e.g. surgery and/or chemotherapy. Utilise computer-based analyses to describe the theoretical interactions of candidate circRNAs within the full complement of RNA and related molecules produced by the tumour cells, called the 'transcriptome', in human PDAC.

The objective of this study is to identify prognosis and predictive markers of response to treatments (surgery, chemotherapy, targeted therapy,loco-regional treatments ) in patients with bile duct cancer. The effectiveness and tolerance of these treatments in current practice will also be evaluated.

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.

To evaluate the efficacy and safety of Cadonilimab in combination with Regorafenib and Gem-Cis chemotherapy in advanced biliary tract Cancer

To investigate onset of adverse drug reactions in patients with curatively unresectable biliary tract cancer who receive IMFINZI in combination with gemcitabine hydrochloride and cisplatin under actual use in the post-marketing setting.

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.

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.

Background: Malignant mesothelioma is a malignancy arising from the mesothelial cells of the pleura, peritoneum, pericardium, or tunica vaginalis. Mesothelioma accounts for 0.10% of deaths annually in the United States. Malignant pleural mesothelioma is the most common of these, comprising of 80% of the cases with an annual incidence of about 2,500 in the United States. The median survival from diagnosis of pleural mesothelioma is approximately 12 months. The majority of patients present with stage III or IV disease with 85-90% of patients considered unresectable at diagnosis. Peritoneal mesothelioma has a better prognosis than pleural mesothelioma; nevertheless, patients undergoing therapy for peritoneal mesothelioma have few well-studied treatment options due in large part to the rarity of the disease. Objectives: -To allow sample acquisition for use in the study of mesothelioma. Eligibility: All patients age greater than or equal to 2 years with malignant mesothelioma Must be able and willing to provide informed consent if 18 or over; parent or guardian must be able and willing to provide consent for patients under the age of 18 Design: Up to 1000 subjects will be enrolled. Patients will be followed to determine the course of disease and to record any treatment received for mesothelioma. Patients will undergo sampling of blood, urine, tumor and abnormal body fluids for tissue banking. Studies which may be performed on banked material include genetic and genomic studies, establishment of cell cultures and immunologic studies.
