Filter by:Pancreaticoduodenectomy (whipple procedure) is the standard operation for tumors of the pancreatic head, uncinate process, distal common bile duct as well as the papilla of vater. For reconstruction, pylorus-preservation (PPPD) has been shown to be technically and oncologically equivalent to the traditional whipple operation. One issue with this technique is delayed gastric emptying (DGE), which occurs in 25-70% of patients, usually emerging between day 4 and 14 after surgery. Patients with severe DGE can not only experience prolonged length of hospital stay, but are also at increased risk for other complications like aspiration or other issues related to the inability to ingest nutrition. There is vast retrospective evidence and one prospective study indicating that antecolic reconstruction of the duodenojejunostomy can improve the rate and severity of delayed gastric emptying. The investigators have conducted a prospective randomized trial in order to test this hypothesis. Patients were randomized to either undergo antecolic or retrocolic reconstruction after PPPD. On day 10 after surgery, DGE was assessed by clinical criteria. In addition, a test meal including 1g paracetamol was administered to check for clinically inapparent DGE. Of these serum samples, kinetics of intestinal peptides like GLP-1, PYY and glucagon was alos measured.
This study involves the administration of a hypoxia marker, pimonidazole hydrochloride, taken orally approximately 24 hours before surgical resection of a pancreatic tumor in order to identify areas of lower oxygen content on tumor samples.
High doses of gabapentin are associated with pancreatic acinar cell tumors in rats, but there has been no post marketing pancreatic carcinogenicity signal with gabapentin as reported by spontaneous reports in AERS or in the published literature. In a published case-control screening study of the association of gabapentin with 55 cancers, the only cancer that met the screening criteria for possibly increased cancer risk with gabapentin exposure was renal (including renal pelvis) cancer. This association was judged to be likely due to or substantially accentuated by confounding by cigarette smoking, hypertension, and lifestyle (Cancer Causes Control 2009;20:1821-1835). The relationship between gabapentin exposure and pancreatic cancer and renal cancer is studied in NCT01138124, and supplemental analyses for these cancers are performed in the current study. The FDA recommended GSK also study the relationship between gabapentin and all-cancer sites, as well as cancer at the following specific sites: 1) stomach, 2) anus, anal canal, and anorectum, 3) lung and bronchus, 4) bones and joints, 5) breast, 6) penis, 7) urinary bladder, and 8) other nervous system. The primary objective of this study is to determine whether exposure to gabapentin is associated with an increased risk of developing all-cancer, and these specific cancers in the United Kingdom (UK) General Practice Research Database (GPRD). Each member of the UK population is registered with a General Practice, which centralizes the medical information not only from the general practitioners themselves but also from specialist referrals and hospital attendances. Over 487 General Practices contribute data to the GPRD. The study cohort from which cases and controls are drawn is all subjects in the GPRD 1993-2008. Gabapentin was approved in the UK in May 1993. Entry into the study cohort begins Jan 1, 1993 for all those who are registered in GPRD before that time, and at the time of registration if later than Jan 1, 1993. Subjects are excluded from the GPRD cohort if they have a cancer diagnosis or a history of cancer prior to the cohort entry date. Patients with a first diagnosis of the respective cancer 1995-2008 are risk set matched with up to 10 controls within the same General Practice for age at cohort entry (within two years), sex, and year of entry into the study cohort (within one year). For cases, the index date is the date of first diagnosis of the respective cancer. The index date for controls is set as the date at which the follow-up time from cohort entry is the same as the case. The index date is chosen so as to give the control equal follow-up time to that of the case for ascertainment of use of gabapentin. Cases and controls will be required to have at least 2 years of follow-up in the study cohort before their index date. Cases must have no history of any other cancer diagnosis prior to the index date. Controls are required to be free of cancer diagnosis in the database up to the control's index date. Data on gabapentin prescriptions are obtained for cases and controls from study cohort entry to the index date. Gabapentin exposure will be assessed as ever/never, number of prescriptions, cumulative dose, and cumulative duration, with a 2 year lag period incorporated to control for protopathic bias (gabapentin prescription for initial pain symptoms of undiagnosed cancer) and latency (time between cancer onset and specific GPRD cancer diagnosis). Crude and adjusted odds ratios and 95% confidence intervals (CI) will be produced from conditional logistic regression models, with additional analyses evaluating for dose-response. Covariates include indications for gabapentin use and risk factors for each cancer.
The research purpose of this project is to create a registry, and blood and tissue bank for individuals at high-risk for pancreatic cancer. We plan to conduct histopathological and molecular analysis of resected pancreatic tissue prospectively collected from a cohort of pancreatic cancer patients.
This study will evaluate efficacy, safety and tolerability of Avastin versus placebo added to a chemotherapeutic regimen in patients with metastatic pancreatic cancer. The anticipated time of study treatment is until confirmed evidence of disease progression, and the target sample size is 500+ individuals.
Patients with pancreatic cancer are treated with combinations of surgery, radiation therapy and chemotherapy, depending on the location of the cancer and other individual patient health factors. The goals of therapy are to reduce or eliminate the cancer cells, but without serious damage to normal cells. Investigators at The University of Michigan are conducting a research project, to see if treatment effects on an individual patient's cancer cells can be detected early by new imaging tests in patients with resectable pancreatic cancer undergoing neoadjuvant chemoradiotherapy.
The aim is to propose and prospectively validate a diagnostic approach and model for prediction of mucinous versus non-mucinous, and malignant versus non-malignant pancreatic cysts using a combination of clinical, radiologic, and biomarker characteristics.
The purpose of this study is to: Find out the largest dose of sodium bicarbonate that can be given with gemcitabine. Determine if the combination of sodium bicarbonate and gemcitabine produces better control of pancreatic cancer than gemcitabine alone.
Covered self expandable metal stents (CSEMS) are three times larger in diameter than 10 Fr plastic stents. When compared to plastic stents, randomized trials have shown longer patency and fewer stent-related complications for CSEMS. The investigators hypothesize that placement of CSEMS would be a better treatment option for preoperative biliary decompression in patients with pancreatic cancer.
The purpose of this study is to test the safety and determine the optimal dose of a new experimental drug, demcizumab (OMP-21M18), when given in combination with gemcitabine with or without (+/-) Abraxane®. Historically, single agent gemcitabine has been the standard treatment for pancreatic cancer. However, recent data suggests that gemcitabine plus Abraxane® may be superior to gemcitabine alone, thus this combination is emerging as the new standard therapy for pancreatic cancer. However, Abraxane® has not been approved for the treatment of pancreatic cancer at this time. Demcizumab is a humanized monoclonal antibody and was developed to target cancer stem cells. This study is sponsored by OncoMed Pharmaceuticals, which is referred to as OncoMed or the Sponsor in this consent form. The study is designed to test the safety of demcizumab at different dose levels when given with gemcitabine +/- Abraxane® and the effects, both good and bad, that it has on participants. Demcizumab may block the growth of cancer stem cells, the remaining tumor cells, and it may also prevent the growth of new blood vessels that tumors need to grow and spread. Although demcizumab has been administered with gemcitabine to cancer patients, it has not been given in combination with gemcitabine and Abraxane®; thus, it is not known if it will provide any benefit to participants and may cause harmful side effects.
