Filter by:This is a Phase II , Open-label , Investigator-initiated Trail of Sequential GEMOX/NS Chemotherapy in Patients With untreated Pancreatic cancer. This study aims to evaluate the safety and efficacy of Sequential GEMOX/NS Chemotherapy as a first-line treatment of untreated Pancreatic cancer.
This phase I trial studies the sides effects and best dose of hydroxychloroquine when given together with trametinib in treating patients with pancreatic cancer that has spread to nearby tissue, lymph nodes or other places in the body and cannot be removed by surgery. Trametinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as hydroxychloroquine, 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. Giving trametinib together with hydroxychloroquine may work better in treating patients with pancreatic cancer.
This study will investigate the tumor-associated vasculature of patients with solid tumors. The investigators will use a technology known as intravital microscopy (IVM) in order to visualize in real-time the vessels associated with solid tumors. The IVM observations may determine if an individual patient's tumor vessels would be amenable to receiving systemic therapy, based on the functionality of the vessels.
Relapses free survival will be evaluated as efficacy of carbon ions radiation therapy released before surgery.
The investigators are going to explore the diagnostic and prognostic value of circulating tumor cells and exosomes extracted from the portal venous blood obtained with endoscopic ultrasound in pancreatic cancer patients.
It will be investigated whether it is possible to predict the effect or lack of effect of first-line treatment by analysing cancer cells from the individual patient receiving standard first line treatment. Also, the feasibility of selecting second-line therapy based on pre-treatment biopsies will be investigated. Cells from pancreatic cancer will be grown in the laboratory to form small, circulating tumors and adjacent tissue, so called tumoroids. The tumoroids will then be exposed to different pre-specified anticancer drugs to hopefully reveal sensitivity or lack of sensitivity in the specific patient.
A randomised clinical trial to compare the clinical efficacy of multiple plastic stents to fully covered self expanding metal stents in the palliation of distal malignant biliary obstruction in patients with irresectable tumours.
Pancreatic ductal adenocarcinoma (PDAC) has a suboptimal response to standard therapies that modestly impact survival due to its ability to evade host immune surveillance. Emerging evidence has shown that the co-inhibitory receptors, such as programmed death 1 (PD-1), play a critical role in cancer immune-editing. Programmed death-ligand 1 (PD-L1) is an immune checkpoint that is often activated in cancer and plays a pivotal role in the initiation and progression of cancer. The advent of immunotherapy, with checkpoint inhibitors, which block PD-L1 interaction between tumor cells and activated T cells, has significantly altered the treatment algorithm for several solid tumors. However, the clinicopathologic significance and prognostic value of PD-L1 in PDAC remains controversial. The main technical ground may be that PDAC PD-L1 expression quantification is limited to surgical resection specimens and dependent on specific immunohistochemistry (IHC) tests. In addition, PD-L1 expression has not been extensively assessed before surgery in treatment-naive PDAC patients, due to the current IHC test requirement for a histologic rather than a cytologic evaluation. However, a recent study showed that EUS-fine needle biopsy (FNB) can successfully determine primary pancreas malignancy PD-L1 status. One recently identified subtype within the genomic landscape of PDAC is the mismatch repair-deficient (dMMR) tumor. Evaluation of dMMR status is particularly important following the FDA approval of the PD-1 inhibitor, pembrolizumab, for the treatment of unresectable or metastatic, microsatellite instability-high (MSI-H) or dMMR PDAC that have progressed following prior treatment, and have no satisfactory alternative treatment options. The objectives of the project will include the assessment of tumor PD-L1/dMMR expression in patients with PDAC using EUS-FNB samples and the prospective correlation of MMR status and PD-L1 expression with overall survival and progression-free survival of PDAC patients.
This trial studies the side effects of self expanding metal stent (SEMS) placement before surgery in unblocking the bile duct in patients with periampullary pancreatic cancer with severe obstructive jaundice. SEMS placement unblocks the bile duct and may help in improving bile drainage prior to surgery in patients with periampullary pancreatic cancer with severe obstructive jaundice.
Diagnostic tools are needed to identify mucinous cysts for further evaluation or follow-up respectively to identify cysts with HGD or invasive cancer at an early stage for surgical resection. Molecular genetic analysis of pancreatic cyst fluid is a new but rapidly evolving method to identify KRAS/GNAS oncogenic driver mutations in mucinous cysts and to identify tumour suppressor gene mutations which are involved in advanced cysts with HGD or carcinoma. The ongoing ZYSTEUS-study tries to implement DNA mutation analysis by Next Generation Sequencing in the diagnostic algorithm of pancreas cyst evaluation. The first aim is to distinguish mucinous from non-mucinous cysts. The second aim is to define relevant tumour suppressor gene mutations which are relevant to distinguish between LGD and HGD/carcinoma in mucinous cysts.
