Filter by:Copy number variation(CNV) refers to ongoing chromosome segregation errors throughout consecutive cell divisions. CNV is a hallmark of human cancer, and it is associated with poor prognosis, metastasis, and therapeutic resistance. Analyzing CNV of the DNA extracted from bile samples in gallbladder seems a promising method for diagnosing, monitoring, and predicting the prognosis of patients with gallbladder cancer. CNV 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 CNV thus helping diagnose gallbladder cancer and assessing follow-up.
Cholecystectomy is amongst the most common surgical operations performed worldwide. Surgical candidates are treated for biliary pathologies, such as biliary colic, cholecystitis and gallstone pancreatitis. In patients who are deemed fit for surgery, cholecystectomy can be performed under three main settings: (1) emergency setting at index admission; (2) elective setting with no previous admissions; or (3) delayed setting with one or more previous gallbladder-related admissions. The advent of laparoscopy fundamentally evolved biliary surgery and quickly became the "gold standard" approach. Recent multicentre collaborative studies have elucidated that the burden imposed on healthcare systems by laparoscopic cholecystectomies is primarily due to patient readmissions and complications arising from the operation, rather than perioperative mortality burden that was more commonly seen in open surgery. As a result, national and international societies have shifted their focus towards creating a culture of safety around this procedure, with the overarching goal of improving patient satisfaction and reducing hospital costs. The universal establishment of safe cholecystectomy is a complex process that relies not only on the operation itself, but also on various other factors such as promoting adequate training, improving hospital infrastructure, and enhancing perioperative patient care. There remains a paucity of evidence around the variations of safe provision of laparoscopic surgery for gallbladder disease internationally, including low- and middle-income countries. To bridge this knowledge gap, the Global Evaluation of Cholecystectomy Knowledge and Outcomes (GECKO) study (GlobalSurg 4) will be an international collaborative effort, delivered by the GlobalSurg network, that will allow contemporaneous data collection on the quality of cholecystectomies using measures covering infrastructure, care processes and outcomes. It will be disseminated via contacts from the National Institute for Health and Care Research (NIHR) Global Surgery unit, leading emergency general surgeons and specialist organisations.
Multicenter German- Registry of Incidental Gallbladder Carcinoma combining clinical real-world data and comprehensive genomic profiling. The registry collects medical data from clinical observation and molecular data derived from archival tumor tissue samples but does not define any medical intervention nor does it evaluate the efficacy or safety of the treatment decision made by the investigator.
This phase II trial investigates the effect of combining two immune therapies, atezolizumab and CDX-1127 (varlilumab), with or without cobimetinib, in treating patients with biliary tract cancer that cannot be removed by surgery (unresectable). Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Varlilumab is an immune agonist antibody that may further strengthen the immune system's attack on the cancer. Cobimetinib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps slow or stop the spread of cancer cells. Giving atezolizumab in combination with varlilumab and cobimetinib may work better than atezolizumab and varlilumab alone in treating patients with unresectable biliary tract cancer.
This study is an open-label, international, multi-center, Phase 2 study in adult patients with recurrent, locally-advanced or metastatic solid tumors, which harbor the NRG1 gene fusion.
The study is a multicenter phase II randomized controlled trial. The purpose is to investigate the efficacy and safety of adjuvant immunotherapy combined with chemoradiation for patients with high-risk resectable extrahepatic cholangiocarcinoma and gallbladder cancer.
Considering that the poor prognosis of resected biliary tract cancer and negative impact on the survival outcomes of R1/R2 resection, neoadjuvant chemotherapy may improve R0 resection rates and the survival outcomes of patients with resectable biliary tract cancer. The addition of durvalumab to gemcitabine/cisplatin as neoadjuvant chemotherapy may improve the R0 resection rates compared to gemcitabine/cisplatin in patients with localized biliary tract cancer. In this phase 2 trial, a total of 45 patients with localized biliary tract cancer will be 2:1 randomized to durvalumab plus gemcitabine/cisplatin or gemcitabine/cisplatin.
This phase Ib trial studies side effects and best dose of dasatinib in preventing oxaliplatin-induced peripheral neuropathy in patients with gastrointestinal cancers who are receiving FOLFOX regimen with or without bevacizumab. Drugs used in chemotherapy, such as leucovorin, fluorouracil, and oxaliplatin (FOLFOX regimen), work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. However, the buildup of oxaliplatin in the cranial nerves can result in damage or the nerves. Dasatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Blocking these enzymes may reduce oxaliplatin-induced peripheral neuropathy.
This phase III trial studies how well gemcitabine hydrochloride and cisplatin given with or without nab-paclitaxel work in treating patients with newly diagnosed biliary tract cancers that have spread to other places in the body. Drugs used in chemotherapy, such as gemcitabine hydrochloride, cisplatin, and nab-paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not known if giving gemcitabine hydrochloride and cisplatin with or without nab-paclitaxel may work better at treating biliary tract cancers.
The FANCY study will investigate whether a selective policy of histopathological examination of appendices and gallbladders based on the intraoperative findings of the surgeon is safe and cost-effective.
