TC-510 is a novel cell therapy that consists of autologous genetically engineered T cells expressing two synthetic constructs: first, a single-domain antibody that recognizes human Mesothelin, fused to the CD3-epsilon subunit which, upon expression, is incorporated into the endogenous T cell receptor (TCR) complex and second, a PD-1:CD28 switch receptor, which is expressed on the surface of the T cell, independently from the TCR. The PD-1:CD28 switch receptor comprises the PD-1 extracellular domain fused to the CD28 intracellular domain via a transmembrane domain. Thus, the switch is designed to produce a costimulatory signal upon engagement with PD-L1 on cancer cells.
This is an open-label positron emission tomography/computed tomography (PET/CT) study to investigate the diagnostic performance and evaluation efficacy of 68Ga-NOTA-exendin-4 in insulinoma and nesidioblastosis patients. A single dose of 55.5-111 Mega-Becquerel (MBq) 68Ga-NOTA-exendin-4 will be injected intravenously. Visual and semiquantitative method will be used to assess the PET/CT images.
Lymph node metastases are a strong prognostic predictor for pancreatic cancer. Para-aortic lymph nodes (PALN) are the final nodes for periampullary cancers before the cancer cells enter the systemic lymphatic circulation. Some consider these nodes to be regional lymph nodes and dissect them as a part of a routine lymphadenectomy for pancreatic cancer. Others argue that metastases to these nodes represent systemic disease and recommend that radical surgery including extended lymphadenectomy should be abandoned.
The aim of this study is to define the incidence and clinical consequences of PALN metastasis in patients submitted to a tentative curative resection for carcinoma of the head of the pancreas by systematically resecting paraaortic lymph nodes.
Primary outcome
1) To determine incidence of PALN metastasis in patients submitted to a tentative curative resection
Secondary outcomes
1. To determine prognosis of patients with PALN metastasis after a curative resection
2. To determine incidence of metastasis in reginal lymph nodes in patients submitted to a tentative curative resection.
3. To determine prognosis of patients with metastasis in regional lymph nodes in patients submitted to a tentative curative resection.
4. To address the question of how to optimize the frozen section analyses of PALN as related to the final pathology report.
300 patients are planned to be included in the trial.
Malignant bile duct obstruction is a common sequela of pancreatic cancers or distal bile duct cancers, and its development can hinder the use of chemotherapy, decrease patient quality of life, and decrease survival. To relieve obstructive jaundice as a result of the obstruction, endoscopic stent placement is usually required. The use self-expandable metal stents (SEMSs) have been shown to result in a longer patency times as compared with plastic stents. However, despite improvements in materials and stent design, stent obstruction still occurs in 13% to 44% of the patients. Tumor in-growth is the most common mechanism of stent obstruction.
Recently, the use of endoscopic biliary radiofrequency ablation (EBRFA) have been described in patients suffering from inoperable malignant distal common bile duct (CBD) obstruction. The procedure uses heat energy to cause local tumour tissue death, resulting in re-opening of the bile duct lumen. The procedure has the potential of reducing the rate of stent obstruction after SEMS and also prolonging survival. The safety profile appears to be comparable that of placement of SEMS alone without added complications (<10%). The aim of the current study is to compare the efficacy of EBRFA with the addition of SEMS to SEMS alone in a randomized controlled trial.We hypothesize that the application of EBRFA can reduce recurrent biliary obstruction after SEMS.
RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in peptides and proteins and identify biomarkers related to cancer.
PURPOSE: This research study is looking at blood samples from patients with malignant melanoma, metastatic breast cancer, advanced lung cancer, pancreatic cancer, or colorectal cancer.
The Precision-Panc Master Protocol is a "portal" protocol for patients with known or suspected pancreatic cancer to be accrued through multiple centres in the UK, with the option of being subsequently enrolled into PRIMUS (Pancreatic canceR Individualised Multi-arm Umbrella Studies) examining different treatment regimens and/or biomarker development. Eligible patients will undergo tumour biopsy and blood collection prospectively for molecular profiling at a central laboratory and the results may be used to inform enrolment to PRIMUS studies.
Currently, there are no standard treatment and relevant exploration for solid tumors patients with NED. The study aims to explore the efficacy and safety of surufatinib combined with serplulimab and standard chemotherapy in the treatment ofadvanced solid tumors with NED, in order to provide a new treatment option for advanced solid tumors patients with NED.
A phase II trial to assess the activity and safety of PD0332991 in patients with well- and moderately-differentiated metastatic pancreatic neuroendocrine tumors (pNET) with overexpression of cell cycle markers (Cdk4 and/or phospho-Rb1 and/or cyclin D1)
Study to assess the safety and tolerability of repeated doses of an investigational new drug in patients with cancer and cachexia.
This phase II trial studies how well liposomal irinotecan, leucovorin, and fluorouracil work in treating patients with high grade neuroendocrine cancer of gastrointestinal, unknown, or pancreatic origin that does not respond to treatment and has spread to other places in the body. Lliposomal irinotecan may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as fluorouracil and leucovorin, 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 liposomal irinotecan, leucovorin and fluorouracil may work better in treating patients with neuroendocrine cancer.
