Filter by:Background • A major increase in incidence of signet ring cell adenocarcinomas (ADCI) of the upper digestive tract in western countries - Discordant results in the literature concerning the prognosis value of the presence of signet ring cells. - Preliminary data suggesting (i) an advanced stage at time of diagnosis, (ii) more often in the form of carcinose, (iii) a more pejorative prognosis, (iv) a recurrence more frequent, more quickly, and more often in the form of peritoneal carcinose, (v) a chemo resistance (vi) the need for a specific therapeutic strategy compared to non-signet ring cell adenocarcinomas. Primary objective To test the hypothesis that 5-year survival rate is significantly lower in the signet ring cells (SRC) adenocarcinoma when compared to non-SRC adenocarcinoma in the upper digestive tract Secondary objectives - Impact of neoadjuvant CT on overall survival - Impact and differential diagnostic value of linitis - R0 resection rates - 3 years recurrence free survival - Overall 3 years survival - Prognostic factors - Prognostic value of the presence of a minority quota of signet ring cell - Objective response rate after medical treatment (chemotherapy, radiochemotherapy) in non-resected patients - Tolerance of (radio) chemotherapy for ADCI Methodology Intention to treat retrospective case-control multicentric study A pairing on demographic criteria (age, sex, ASA score, center) and tumor criteria (TNM stage) will be done to ensure comparability in case control study groups. Inclusion criteria All consecutive patients taken care of, for a proven histologically adenocarcinoma (ADCI and ADNCI) of the esophagus, the esogastric junction, or the stomach, in surgical or medical oncology investigator centers, will be saved in a given database. For whom the first consultation took place between January 1997 and January 2010 Exclusion criteria Histological type other than adenocarcinoma Other localization than esogastric junction, esophagus or stomach Planned study period The data will be collected over a period from January 1997 to January 2010. The objective is to complete the data collection for summer 2010.
The capacity for endoscopical procedures in the Norwegian health system is low in comparison to demands from patients and family practitioners. The studies aim is to evaluate the acceptance of a new concept: an open access gastroscopy clinic where patients can attend without a preceding appointment. The investigators wish to evaluate: 1. Patient´s satisfaction. 2. General practitioner´s satisfaction. 3. Acceptance by the staff of the clinic.
Patients who require gastric endoscopy, including the patient population* excluded from the phase III controlled clinical study of NPO-11, will receive an intragastric single dose of NPO-11 20 mL. The efficacy of NPO-11 as a premedication for endoscopy will be evaluated based on the percentage of patients having no gastric peristalsis at both 2 minutes post-dose and the end of endoscopy (primary outcome measure). The safety of NPO-11 will be evaluated based on adverse events and adverse drug reactions (ADRs) observed between administration and seven days after administration. Patient population excluded from the phase III controlled clinical study of NPO-11 - Patients with reflux esophagitis - Patients with active gastric or duodenal ulcers - Patients who undergo endoscopy under sedation - Patients who undergo endoscopy with a scope of <9 mm in diameter
The purpose of this study is to determine the correlation between gastric residence time of the SmartPill Capsule and the time required for partial emptying of a standard radiolabeled meal as measured by gastric emptying scintigraphy for subjects 65 years of age and older.
Primary objective: To determine the levels of malondialdehyde (MDA) and immunohistochemistry surrogate of inflammation in patients with NSAID-induced gastric mucosal injury treated with Rebamipide 3x a day vs Esomeprazole 40mg once a day. Secondary objective: For patients who become symptomatic during NSAID treatment, to compare the proportion of patients with positive treatment effects using the Likert scale. Third objective: To compare the proportion of patients with positive treatment effects as determined by Modified Lanza scoring between the two groups.
Functional dyspepsia is a common gastrointestinal disorder. Symptoms can include stomach pain or discomfort, bloating, fullness after eating meals, and nausea. These symptoms often interfere with school and work, and weight loss may occur due to dietary restrictions. The hypothesis of this study was that antidepressant therapy is more effective than placebo in relief of the symptoms of functional dyspepsia, adjusting for psychological and psychiatric co-morbidity. The study also examined if antidepressant therapy reduces disability and improves quality of life in functional dyspepsia.
Helicobacter pylori (Hp) is a major cause of chronic-active gastritis and primary duodenal ulcers, and is strongly linked to gastric cancer. Most Hp infections worldwide are acquired in childhood. Why some individuals develop symptomatic disease is unclear and, until recently, no studies critically evaluated the role of pediatric Hp strains and/or host factors in disease outcomes. Over the past 5 years of National Institutes of Health (NIH) funding, 486 children from Atlanta, Cleveland, and Miami were enrolled; 184 (38%) were Hp-infected. Race (African American) and younger age, in conjunction with Hp strains expressing cagA and vacAs1B, were shown to be risk factors for both esophageal and gastric disease, suggesting a different disease paradigm from Hp-infected adults. Using the updated Sydney system, the investigators demonstrated a histopathologic spectrum in children, which included novel observations of atrophic gastritis with intestinal metaplasia. Overall hypothesis for competitive renewal: disease manifestations in Hp-infected children are influenced by specific host factors (i.e., race, immune phenotype), environmental exposures, and specific virulence factors of infecting Hp strains. Specific aims: 1. Using well defined cases and controls, further characterize specific host factors and environmental exposures contributing to symptomatic childhood infection emphasizing targeted enrollment in specific age, gender and demographic strata to facilitate detection of significant differences not attained previously and follow-up of 2 established specific cohorts to ascertain immune response natural history. 2. Utilize gene-array technology for the whole Hp genome assessment and bacterial gene expression of specific virulence determinants associated with pediatric Hp strains. 3. Further characterize the host immunologic and mucosal response in Hp-infected children. Hp-infected symptomatic endoscopy cases at the investigators' established 3 clinical centers of high, moderate and low Hp prevalence will be compared with age-matched Hp-infected asymptomatic and uninfected symptomatic controls. Two geographically and demographically distinct centers have been added to provide additional geographic and subject representativeness to the patient cohort. The updated Sydney system will be employed to assess gastric histopathology severity and phenotype in newly enrolled cases in specific age, gender and demographic strata and follow-up of the two "novel" cohorts established in the past 5 years: a) atrophic gastritis; and b) esophageal and gastric disease groups enabling a comprehensive, multivariate evaluation of the natural history of Hp-infected children in two distinct disease paradigms. Using molecular methods (multiplex [MP]-PCR, RT-PCR) and a micro ELISPOT assay on peripheral blood mononuclear cells (PBMCS), Th1, Th2, Th3 or balanced Th1/Th2 response will be determined to further characterize the Hp-infected child's immune response phenotype. The investigators propose to further their previous work with critically lacking studies from a multivariate approach, leading to a better understanding of the gastroduodenal disease sequelae and overall pathobiology of Hp infection in humans.
