Active clinical trials for "Neoplasms, Cystic, Mucinous, and Serous"

To assess the effect of RG1068 at a dose of 0.2 mcg/kg intravenously (IV) on the diameter of the pancreatic duct when used during Magnetic Resonance Pancreatography To demonstrate that RG1068-enhanced MRCP improves detection and characterization of intraductal papillary mucinous neoplasms (IPMN) relative to unenhanced MRCP in patients with suspected IPMN To correlate findings on MRCP with histologically confirmed malignancy

Cystic tumors of the pancreas are fluid-filled growths. They are often treated by surgical removal. A safe and effective non-surgical treatment is desirable. Ethanol (alcohol) injection may treat cysts by killing the lining cells of the cyst, and is an accepted treatment for cysts of other organs. In this study, participants with pancreatic cysts underwent endoscopic ultrasound (EUS) guided ethanol injection of pancreatic cysts. This was a pilot study to assess safety and efficacy. The hypotheses of this study were 1) complications of EUS guided ethanol injection requiring hospitalization will occur in <10% of subjects, and 2) EUS guided ethanol injection, with retreatment as necessary, will ablate at least 50% of pancreatic cysts.

The purpose of this study is to track outcomes and complications of patients at IUMC referred by physicians for EUS-guided pancreatic cyst ablation. This information is essential in order to disseminate future published information to physicians about this technique. A database will be created to track these patients undergoing an already scheduled/planned procedure. Phone calls at selected intervals will be made following the procedure to track any complications that occur

To demonstrate the added value of intraoperative pancreatoscopy in patients undergoing partial pancreatic resection for the treatment of Intraductal Papillary Mucinous Neoplasm (IPMN) as it pertains to detection of discontinuous (skip) lesions in the remnant pancreas; to generate a hypothesis for a subsequent randomized control trial.

This phase I trial studies the side effects and best dose of talazoparib and heat shock protein (HSP)90 inhibitor AT13387 when given together in treating patients with solid tumors that have spread to other places in the body (metastatic) or ovarian, fallopian tube, primary peritoneal, or hormone negative breast cancer that have come back after a period of improvement (recurrent). Talazoparib and HSp90 inhibitor AT13387 may stop the growth of tumor cells by blocking some enzymes that are need for cell growth. HSp90 inhibitor AT1338 may also help talazoparib work better by making tumor cells more sensitive to the drug.

The overlap of morphological imaging features results in many incidentally detected pancreatic cystic neoplasms going undiagnosed, including benign serous cystic neoplasms (SCN) and potentially malignant mucinous lesions (nonserous). The diagnostic ambiguity then lead to invasive procedures such as endoscopic ultrasonography (EUS), unwarranted surgical resection on SCN lesions or the need for long term periodic surveillance with delayed diagnosis of potentially malignant nonserous lesions. Therefore, precise differentiation of SCN from nonserous cystic neoplasms is highly desirable. The 18F-fluorodeoxyglucose (FDG) accumulation in tumor cells, which is induced by high expression of glucose transporter proteins (mainly include GLUT-1 and -3), can be used to discriminate malignant and benign pancreatic cystic tumors in positron emission tomography (PET) imaging. GLUT-1 expression has also been documented in benign SCN while no such evidence exists in potentially malignant nonserous cystic neoplasms. Based on this evidence, investigators will conduct a pilot study to evaluate if integrated 18F-FDG PET/MR imaging with simultaneous MR and PET acquisition is helpful in differentiation of SCN from nonserous lesions.

Pancreatic cysts are common, and some pancreas cysts have malignant potential. Usual treatment of these cysts is either observation or surgical removal of part or all of the pancreas. Minimally invasive treatment via endoscopy has been described, using endoscopic ultrasound (EUS) guided ethanol injections. Such studies exclude cysts that communicate with the main pancreatic duct, to avoid burning the main pancreatic duct with ethanol. In this study, pancreas cysts communicating with the main pancreas duct are treated with ethanol via endoscopic retrograde cholangiopancreatography (ERCP) and/or EUS.

Incidental pancreatic solid or cystic lesions are diagnosed with increased frequency due to the widespread use of abdominal cross-sectional imaging to investigate unrelated symptoms. Lesions such as neuroendocrine tumors (NET), mucinous cystadenomas and intraductal papillary mucinous neoplasms (IPMNs) have the potential of malignant transformation. The standard treatment of solid or cystic pancreatic lesions with malignant potential has been surgical resection, with lesions in the pancreatic head requiring a Whipple resection whereas pancreatic tail lesions are treated with distal pancreatectomy. Both types of resection carry significant morbidity and mortality. The study would like to outline the feasibility, safety, adverse events and early results of endoscopic ultrasound (EUS) - radiofrequency ablation (RFA) in pancreatic neoplasms.

A multicentre phase II study to determine the safety and efficacy of EUS-guided nCLE in patients with suspected cystic tumours of the pancreas in whom endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is clinically indicated. Patients will be recruited sequentially to undergo nCLE as part of their routine diagnostic evaluation, followed by standard surveillance. This part of the study will recruit 60 patients.

Study objective: To establish a long-term follow-up cohort of patients with IPMN, study the follow-up, clinical outcomes and prognostic factors of patients with IPMN, and provide a basis for clinical decisions and guidelines. Study design: This is a real world, multicenter, prospective, observational cohort study
