Filter by:The purpose of this study is to see if a combination of paclitaxel protein bound (also known as nab-paclitaxel), gemcitabine, and cisplatin when given with high dose Ascorbic Acid will be safe and effective in individuals with untreated metastatic pancreatic cancer. Vitamin C is a nutrient found in food and dietary supplements. It protects cells and also plays a key role in making collagen (which provides strength and structure to skin, bones, tissues and tendons). High-dose vitamin C may be given by intravenous (IV) infusion (through a vein into the bloodstream) or orally (taken by mouth). When taken by intravenous infusion, vitamin C can reach much higher levels in the blood than when the same amount is taken by mouth. Some human studies of high-dose IV vitamin C in patients with cancer have shown improved quality of life, as well as improvements in physical, mental, and emotional functions, symptoms of fatigue, nausea and vomiting, pain, and appetite loss. Intravenous high-dose ascorbic acid has caused very few side effects in clinical trials.
This is an open-label, dose-escalation, phase I trial of the safety and efficacy of anti-CEA intraperitoneal CAR-T infusions for treatment in patients with CEA-expressing adenocarcinoma peritoneal metastases or malignant ascites.
The relationship between myopenia, nutritional status, and long-term oncologic outcomes remains poorly characterized in patients with anatomically resectable pancreatic cancer (PC). The investigators want to look at muscle properties in pancreatic cancer patients to determine possible therapeutic options toward better nutritional status. Patients with benign right upper quadrant pathology will be utilized as controls for the study. The researchers hypothesize that improving cancer cachexia in PC will improve the quality of life and ultimately increase overall survival. The long term goal of is to identify areas of intervention to prevent and/or improve cachectic events in PC in order to significantly improve clinical outcomes. The first step in this long term goal is to fully characterize cachexia in the condition of PC. This research is to understand and modify the local response within skeletal muscle leading to a clinically relevant persistent wasting and to understand and interrupt the systemic stimulus produced by the tumor local environment resulting in these muscle specific mechanisms.
The main purpose of this study is to evaluate the acceptance by patients with metastatic pancreas cancer of integrating palliative care with usual cancer treatment. Palliative care intervention will involve use of pancreas cancer-specific decision aides (iPC3)about prognosis, treatment choices, and advance care planning for patients facing a treatment decision as well as symptom assessments. We hypothesize that palliative care consultations with iPC3 will be accepted, symptoms can be diminished, information can be received in a way that improves choices, and that the quality of care can be improved.
Accurate preoperative tumor detection and staging are fundamental for treating patients with pancreatic adenocarcinoma. Patients with unresectable tumors can benefit from being spared an extensive operation associated with substantial morbidity and mortality, cost, and pain. On the other hand, patients with localized disease, which is amenable to surgical removal, have the option of operation. Therefore, accurate staging of pancreatic cancer requires the detection of the tumor, and evaluation of its size, its relationship to major peri-pancreatic vascular structures and portal venous system, locoregional lymph nodes, and distant metastases. Multiple imaging techniques have been used to evaluate the pancreas. Although, at this point, no consensus exists as to the best staging algorithm, multidetector (MD) computed tomogrophy (CT) and Magnetic resonance imaging (MRI) provide sufficient information for the management of most patients. Patients with a tumor larger than 3 cm are characterized as non-surgical. CT sensitivity in detecting small pancreatic tumors of less than 2 cm is low. Multiple methods have been suggested to increase the sensitivity of CT. The sensitivity of CT increases with using multidetector CT which now has an accuracy rate of about 95-97% for initial detection and approximating that of 100% for staging. Secretin (a natural hormone produced by the duodenal mucosal cells) is known to increase blood flow to the pancreas. The principal use of secretin in imaging today is in exocrine function of the pancreas or morphological evaluation of the pancreatic duct under ultrasound or MRI. Theoretically, pancreatic contrast enhancement should also increase after secretin administration. This would imply that tumor conspicuity might also be increased if contrast enhancement of the normal pancreas increases. Secretin CT has been advocated by other centers to improve depiction of the ampulla and periampullary/duodenal diseases and to improve contrast enhancement. O'Connell et al, used secretin in patients suspected or with known pancreatic mass and concluded that administration of intravenous secretin leads to greater enhancement of the pancreas with greater tumor conspicuity, than imaging without secretin. MRI of the pancreas has undergone a major change because it can provide noninvasive images of the pancreatic ducts and the parenchyma. MR cholangiopancreatography (MRCP) enables detection of anatomic variants such as pancreas divisum. Although contrast material-enhanced CT is still considered the gold standard in acute pancreatitis and for the detection of calcifications in chronic pancreatitis, MR imaging and secretin-enhanced MRCP are useful in evaluating pseudocysts and pancreatic disruption. The role of MR is still debated in pancreatic neoplasms except the cystic lesions where MR imaging provides critical information regarding the lesion's content and a possible communication with the pancreatic ducts. Although some articles have shown that MRI was equivalent to CT in diagnosis and staging, others have shown the opposite. Nishiharu et al. found comparable tumor detection but a benefit with CT, notably for peripancreatic and vascular invasion. Comparing CT, echoendoscopy, and MRI, Soriano et al. demonstrated that CT showed the highest level of precision in primary tumor staging, local-regional staging, vascular invasion, distant metastases, Tumor, node, metastasis (TNM) staging, and tumor resectability. MRI retains its originality in imaging the parenchyma, the pancreatic and biliary ducts, and vascular structures; however, in many institutions, CT remains the reference imaging choice for diagnosing and staging pancreatic cancer. Other than CT's advantages for the tumor, its excellent spatial resolution also provides detailed reconstructions in all planes and arterial mapping and therefore makes it possible to search for surgical contraindications such as celiac trunk stenosis. MRI is still used today as a second-intention tool when there is doubt or when CT and echoendoscopy are not sufficiently conclusive; it is not currently recommended to use MRI in first-intention diagnosis of pancreatic cancer. The aim of this pilot study is to determine whether the administration of intravenous secretin before contrast-enhanced CT and MRI improves pancreatic enhancement and pancreatic tumor conspicuity and to evaluate which technique is more appropriate for pancreatic tumor detection, staging and evaluation of resectability.
We propose to recruit subjects scheduled for pancreatectomy as a treatment for pancreatic cancer. These subjects will ingest a very low dose of radiolabeled PhIP, a meat-derived carcinogen, and a small amount of resected tissue (waste) will be analyzed with highly sensitive technology to determine if this carcinogen binds to DNA in the pancreas.
