Filter by: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.
Ultrasonic coagulating shears are made for performing for cutting and hemostasis at once during operation. It was proved that a laparoscopic gastric resection showed significantly shorter operative time and less work load distribution, and more stability of bleeding than before an introduction of ultrasonic coagulating shears . In an open gastric cancer surgery, ultrasonic coagulating shears have been often used for lymph node dissection or cutting of small vessels in some hospitals in Korea. However its usefulness or effectiveness has not been fully proved. There was only one report about using ultrasonic coagulating shears in open gastrectomy. The report contained small number of subjects and surgical procedures were different from the investigators. The investigators expect to reduce operative time and blood loss with ultrasonic coagulating shears. Ultrasonic coagulating shears will also enable us to dissect lymph node with closure of lymphatics. This may reduce the amount of drainage fluid from peritoneal cavity and shorten the removal time of a drain, which will also shorten the hospital stay. The objective of this study is to evaluate the safety and benefit of ultrasonic coagulating shears in open gastrectomy including usefulness and effectiveness by a randomized controlled, prospective study.
Our research of the biology of upper gastrointestinal cancers involves the study of tissue samples and cells from biopsies of persons with gastric or esophageal cancer or blood samples from upper gastrointestinal cancer patients and persons at high inherited risk for these cancers. We hope to learn the role genes and proteins play in the development of gastric and esophageal cancer.
The survival of esophageal cancer and stomach cancer (EGC) at 5 years is less than 30%. Pravastatin is a potent inhibitor of HMG-CoA reductase inhibitor that has shown increased survival in patients with advanced hepatocellular carcinoma. The objective is to evaluate the efficacy of treatment (increase in survival and recurrence-free period of the disease) with pravastatin in patients with advanced EGC. The investigators have designed a randomized, controlled and open. Advanced stage was considered for patients with T4 or N1 or M1 according to the TNM classification. It has been estimated sample size per treatment arm of 73 patients (146 patients in total). Randomization was done on a stratified by location (CE or CG). All patients receive hatitual treatment (surgery and / or chemotherapy and / or radiotherapy and / or palliative) for each of their clinical conditions. The experimental group will receive one tablet of 40 mg of pravastatin orally every 24 hours (breakfast) for 2 years. There will be a monthly monitoring of these patients for at least 2 years which includes an analytics. Every 2 months there will be an abdominal-pelvic CT scan to assess progression and treatment response.
The purpose with this study is to evaluate treatment with radio chemotherapy (oxaliplatin and capecitabine) given concommitant with radiotherapy in patients with gastrointestinal tumors. The trial consists ot two separate studies; CORGI-U in patients with stomach- bile ducts- gallbladder and pancreas cancer, and CORGI-L in patients with colorectal cancer. CORGI-U will be designed as a phase-I-II-study,in which the first part will be a chemotherapy dose finding study, followed by a phase II part to establish response rates. All subjects receives radiotherapy concommitant. CORGI-L is a phase II trial, in which patients are treated with chemotherapy at fixed doses with radiotherapy concommitant.
Patient will choose to either receive the standard of care according to National Comprehensive Cancer Network (NCCN) or approved guidelines for their condition or to be treated according to one arm of the protocol that they could not be enrolled on. The selection of the arm will be at physician discretion.
The purpose of this study is to provide educational material to promote screening for second primary cancer for the intervention group, or educational material to instruct appropriate use of dietary supplement for the control group.
There is no clear standard of care for metastatic stomach or esophageal cancer in the United States. The purpose of this research study is to determine the differences between two regimens of chemotherapy; Arm A: PCA (Cisplatin, Irinotecan and Bevacizumab) and Arm B: TPCA (Docetaxel, Cisplatin, Irinotecan and Bevacizumab). Docetaxel, Cisplatin, and Irinotecan are traditional chemotherapy drugs. Bevacizumab is an antibody (a protein that attacks a foreign substance in the body). Bevacizumab is believed to stop the formation of new blood vessels that carry nutrients to tumors. Both of the chemotherapy regimens (PCA and TPCA) have been studied in patients with esophageal and gastric cancer, and we are trying to determine if one regimen will keep your cancer from growing and improve how long you can live.
This study is to evaluate the efficacy and safety of addition of intraperitoneal (ip) Floxuridine to adjuvant chemoradiation therapy for patients under-going potentially curative stomach resection.
This study intends to evaluate the feasibility and treatment efficacy of adding an antibody blocking the epidermal growth factor (EGF) pathway to a neoadjuvant approach with proven efficacy developed at New York University.
