Active clinical trials for "Pancreatic Neoplasms"

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 purpose of this study is to find the best and most sensitive screening modality (CT, MRI, EUS)for very small pre-cancerous pancreatic lesions and to treat these small lesions before they turn into cancer. Another purpose of this study is to search for common markers on DNA that would increase the chance of someone developing pancreatic cancer, and locate proteins in pancreatic juice that indicate tumor development.

Pancreas cancer and precancerous cysts can be difficult to diagnose. Sometimes biopsies do not show cancer when cancer is actually present. We hypothesize that genetic differences exist in tissue that is malignant compared to nonmalignant. When patients present with a pancreas mass or cyst, we biopsy it by fine-needle aspiration during upper endoscopy with ultrasound guidance. We would like to use tissue obtained via endoscopic ultrasound guided fine needle aspiration to perform DNA microarray analysis, and compare the differences in gene expression level in the benign tissue compared to cancerous tissue in order to improve our diagnostic capabilities. DNA microarray measures gene expression level rather than germline mutations. The true diagnosis will be based on cytology, surgical pathology, or clinical followup. The performance of the microarray test as a diagnostic test will be compared to the performance of cytology.

This is a multicenter, international, prospective, observational study of patients who are receiving systemic chemotherapy for solid tumour cancers (breast, colorectal, ovarian, prostate, lung, bladder, endometrial, renal, pancreatic, esophageal or gastric) and who are receiving darbepoetin alfa (Aranesp®) or other erythropoiesis-stimulating agent (ESA) to treat symptomatic anaemia. Quality of Life will be assessed electronically with the aim of estimating improvement in quality of life for those patients receiving darbepoetin alfa (Aranesp®) who also have an increase in haemoglobin (Hb) of ≥1 g/dL

This observational study compared quality of histological sampling of pancreatic EUS-FNB with the 20-gauge Procore® and 22-gauge Acquire® needles. In total, 68 patients were recruited. Histological diagnosis was achieved and a histological core biopsy was obtained in 82% of patients (28/34) in the 20-gauge Procore® group and 97% of patients (33/34) in the 22-gauge Acquire® group (P=0.1). Core biopsy specimens obtained were significantly longer with the 22-gauge Acquire® needle with a mean cumulative length of tissue core biopsies per needle pass of 4,33±3,46mm vs. 7,9±4,35mm for the 20-gauge Procore® (P<0,01). Reproducibility of this simple histological criterion was validated in intra and inter-observer.

The purpose of this study is to compare the diagnosis accuracy of 22G EUS Procore fine needle biopsy （FNB）device and 20G EUS Procore fine needle biopsy device for solid pancreatic lesions.

The aim of this study is to identify new prognostic factors in patients affected by advanced pancreatic carcinoma treated with first line chemotherapy with FOLFIRINOX regimen. Primary objective is the identification of clinical, laboratory and pathologic factors affecting overall survival of these patients.

Today the Whipple procedure is the preferred operation for malignancy in the pancreas. In abdominal surgery this procedure is known for its high surgical stress-response in the patient, which has been attempted to be resolved with the introduction of preoperative high-dose steroids and goal-directed fluid therapy (GDT). Despite this effort, complications still occur regularly (30%) in the first weeks after the operation here at Rigshospitalet. Therefore there is still a challenge in the patients who have undergone the Whipple procedure in the acute postoperative phase. This shows in for example at Rigshospitalet, where 50% of the patients continue to be in the need of vasoactive medication the morning after the operation. Nevertheless, no studies have in detail described the acute (<24h) postoperative phase. There is also an importance in the fact that there is often no description or control over other important factors, for example medicine with influence on the circulatory system, fluid treatment and response to this etc.. The purpose of this study is to investigate what issues or complications, in particular those of circulatory matter that occurs in this particular group of patients 24 hours after the operation. Furthermore there is lacking a description of which cause-response- link there can be between early and later (30 days) complications, as well as when each of these complications occur. Therefore, there will also be collected data on complications within the first 30 days after the operation for the purpose of a later secondary publication with the same authors.

The 18F-FDG-PET scan is currently being used for cancer diagnosis, staging, identifying hidden metastasis, and assessment of treatment responses in clinical oncology. Although there are important studies suggesting potential associations between PET-based parameters and oncologic outcomes, the calculation and official documentation of individual PET-based parameters might not be routine in clinical practice because these processes usually require time- and labor-consuming processes for the radiologists. In this study, the investigators prospectively determined clinical 18F-FDG-PET type according to degree of FDG-uptake in pancreatic cancer and compare oncologic outcomes between the types.

The objective of the study is to evaluate the characteristics of the patients and the results of morbidity and mortality after distal pancreatectomy isolated or accompanied by multivisceral resection including cholecystectomy.
