Pancreatic cancer patients receive chimeric antigen receptor (CAR) T cells against mesothelin (CARTmeso) or CD19 (CART19) cells administered at 3 days via pancreatic artery infusion or i.v. after preconditioning of cyclophosphamide. Both CART cells are autologous. CARTmeso cells target pancreatic cells which highly express mesothelin, while CART19 cells target tumor-associated B cells expressing cluster of differentiation antigen 19 (CD19) which are mostly immunosuppressive. The investigators hypothesize that this combination therapy may enhance the efficacy of CARTmeso cells in the body. Additionally, a medium dose of cyclophosphamide is used to enhance the engraftment of CART cells.
Pancreaticoduodenectomy is associated with a high incidence of postoperative complications. These postoperative complications could delay postoperative resumption of adequate oral intake. Clinical study on postoperative feeding after pancreaticoduodenectomy is very limited. Method of Nutritional support (Enteral feeding or total parenteral support)after pancreaticoduodenectomy is controversial.
1. To evaluate whether early enteral nutrition may be a suitable alternative to total parenteral nutrition
2. To evaluate whether enteral feeding improve nutritional status after pancreaticoduodenectomy
Patients with tumors in liver or pancreas are randomized to ultrasound (UL)-guided FNAC biopsies with guidance method or UL-guided FNAC biopsies with free-hand method.
This study aims to develop XGBoost machine learning model to predict pancreatic neoplasms in CP patients with focal pancreatic lesions.
Endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) is a valid and recommended technique for tissue diagnosis of pancreatic masses. However, the diagnostic yield is with a sensitivity of 64%-95% and an accuracy of 78%-94% still very low. The EUS-FNB of pancreatic masses is usually performed with a 22-gauge biopsy needle. The small diameter of the needle is usually responsible for the low yield of tissue samples for histopathological examination. The 19-gauge needles help to overcome the limitations of a 22-gauge needle by acquiring a larger amount of cellular material. Thus, performing EUS-FNB with a 19-gauge needle can maximize tissue acquisition and sample adequacy, which is important for appropriate diagnosis. Contrariwise, the technical success rate for sample retrieval in patients with pancreatic head lesions is significantly lower using the 19-gauge compared to the 22-gauge needle. This is attributable to the technical difficulty to push the needle out of the endoscope in the duodenum. Since about 60% of pancreatic cancers are located in the head region, it is therefore particularly important to improve technical success in these cases. The new 19-gauge biopsy needle "Olympus EZ Shot3 Plus" is more flexible than common biopsy needles such as ȮZ Shot2" and should therefore provide improved access to regions like pancreatic head. The aim of this multicenter prospective randomized crossover study is to compare those two needles during EUS-FNB of solid pancreatic masses.
Therefore this study will enroll 40 patients in five German centers with solid pancreatic masses and consecutive indication for EUS-FNB. Both needles will be used in each patient following a predetermined random order.
Primary endpoint is the correct histological diagnosis of the mass assessed by each needle. Technical failure is regarded as a negative histological diagnosis.
Secondary endpoints include a comparison of technical failure using each needle, histological quality, duration of procedure and rate of adverse events.
The purpose of this study is for researchers to find ways of detecting pancreatic ductal adenocarcinoma/PDAC early to avoid the invasive procedure of surgery. The study researchers think a combination of imaging and a series of blood tests may be an effective way to detect PDAC early. In this study, researchers will look at whether a combination of the following types of imaging with blood tests can detect PDAC in pancreatic cysts:
* The ImmunoPET scan (immune-positron emission tomography scan) with the imaging agent 89Zr-DFO-HuMab-5B1
* The HP MRI scan (hyperpolarized pyruvate magnetic resonance imaging scan)
The purpose of this study is to evaluate the safety of TAK-164 and to determine the maximum tolerated dose (MTD) and/or recommended phase 2 dose (RP2D) and schedule.
This study is being done to determine whether it is possible to use an investigational vaccine that consists of dendritic cells in patients with pancreas cancer. Dendritic cells are immune cells that are obtained from your blood that are important in the body's immune response to foreign substances. The vaccine would be injected directly into a tumor that has spread to the liver after a short course of radiation therapy has been given to that tumor. The study will try to determine if this treatment would be safe and effective in treating this cancer.
This is a phase 1 pilot study of this treatment. Phase 1 trials test the best way to give a treatment where little is known about its possible risks or benefits. Phase 2 studies then test the possible benefits of a treatment and may show the specific situations where they are seen. Promising treatments are then tested in Phase 3 trials which compare the new treatment to standard treatment in a larger group of patients. Phase 4 trials are those conducted on a treatment after it has been approved for general use outside of research. A pilot study tests a treatment in a small number of patients to learn if and how the treatment could be tested in a larger group. Pilot studies can be performed at any phase but are commonly performed in the earliest phases of research on a treatment.
This study aims to quantify the malignant potential of non-functional neuroendocrine tumors of the pancreatic body and tail ≤ 3 cm by collecting real-world data from large pancreatic centers across the country, and to evaluate the appropriateness of parenchyma-sparing resection and oncologic resection.
This is an open label, multi-center, multi-arm, dose-escalation study of BBI608 administered in combination with Gemcitabine and nab-Paclitaxel, mFOLFIRINOX, FOLFIRI, or MM-398 with 5-FU and leucovorin.
