Active clinical trials for "Stomach Neoplasms"

This pilot clinical trial studies an educational brochure in preparing patients with gastric cancer and their caregivers for recovery after surgery. Giving an educational brochure may help prepare patients and their caregivers by improving knowledge about symptoms after surgery. It may also improve quality of life and reduce worry after surgery.

Early-onset gastric cancer (EOGC) is a lethal malignancy with a poor prognosis. It differs from late-onset gastric cancer (LOGC) in clinical and molecular characteristics. The current strategies for EOGC detection have certain limitations in diagnostic performance due to the rising trend in EOGC. Hence, identifying novel EOGC bioindicators is crucial.

This is a population-based case-control study in all 5 Nordic countries from 1994 onwards. All cases with an esophageal or gastric tumor will be compared with 10 times as many population controls, frequency-matched by age, sex, and calendar year, country. This design offers excellent statistical power, length and completeness of follow-up, quality of data on exposures, outcomes and confounders, and control for confounding. The project will include a specific study entitled "Long-term medication with proton pump inhibitors and risk of gastric cancer", which is summarized here: Research question: Medication with proton pump inhibitors (PPI) (e.g., omeprazole and esomeprazole) is one of the most common long-term therapies globally, prompted by its high anti-acidic efficacy and good short-term safety profile. Gastric cancer is the 3rd leading cause of cancer-related mortality globally, responsible for 770,000 deaths each year. There are clear biological mechanisms linking long-term PPI-use with an increased risk of gastric cancer. However, existing research has not been able to provide a definite answer to whether long-term PPI-use is associated with an increased risk of gastric cancer. The reasons are that the literature is hampered by too short follow-up time to assess cancer development, and also insufficient statistical power, lack of population-based design and confounding. With the availability of nationwide complete medication registries in the Nordic countries, the firsts two starting already in 1994 (Denmark and Finland), we can now, by adding registry data from all Nordic countries together, conduct the first study providing a robust and valid answer to this research question. Overarching aim This project aims to clarify if (and if so to what extent) long-term PPI-therapy influences the risk of developing gastric adenocarcinoma. For validation reasons, we will also examine how long-term use of histamine-2-receptor blockers (H2RB) influences the risk of developing gastric adenocarcinoma. These analyses will validate that the findings are specific for PPIs. H2RB are used for the same indications as PPIs, but with a different biological mechanism. Hypothesis We plan to test the hypothesis that long-term use of PPI (but not H2RB) increases the risk of gastric adenocarcinoma. Prerequisites This will be the first project with all prerequisites to provide conclusive answers to the hypotheses above, i.e.: Long follow-up (up to 28 years) Complete follow-up (by virtue of the nationwide complete Nordic registries) Population-based design (which rules out biased selection of cases or controls) Superior statistical power (all five Nordic countries participate with nationwide data) High-quality data on exposures, outcomes and confounders (thanks to well-maintained and complete nationwide Nordic health data registries) Control for confounding factors (available for all participants, both cases and controls)

Immunonutrition (IN) appears to reduce infective complications and in-hospital length of stay (LOS) after gastrointestinal surgery. More specifically, it seems to be beneficial also in gastric cancer surgery. Potential benefits of combining preoperative IN (PIN) with protocols of enhanced recovery after surgery (ERAS) in reducing LOS in laparoscopic total gastrectomy are yet to be determined.

The aim of this study is to evaluate the efficacy of a neoadjuvant approach in patients with locally advanced gastric cancer and the identification of prognostic factors.

The purpose of this study is to determine whether Electrical Impedance Tomography can be used as sensitive and specific predictor in the detection of postoperative pulmonary complications (e.g. pneumonia, bronchitis, acute respiratory distress syndrome, pleural effusion, pneumothorax, pulmonary edema, atelectasis, pulmonary embolism, hypoxemia, hypercapnia, spasms and obstructions of the airway) in patients undergoing epigastric surgery.

Researchers already did studies in low-dose Aspirin for the prevention of heart and blood vessels disease and for the prevention of cancer of the colorectum. In this study, they want to learn whether an effect for the prevention of oesophagus cancer and stomach cancer goes along with the use of low-dose ASA on patients taking this medicine for the prevention of heart and blood vessels disease compared to non-use. To find this out electronic medical records stored in primary care database in the UK, The Health Improvement Network (THIN), will be used.

Gastric GISTs are rare neoplasms that require excision for cure. Although the feasibility of laparoscopic resection of gastric GIST less than 2cms has been established, the feasibility, safety and long-term efficacy of these techniques for larger lesions are unclear. Investigators hypothesized that laparoscopic resection of gastric GISTs even for larger lesions is feasible & results in low perioperative morbidity and an effective long-term control of the disease.

Objective. The objective of the study is to verify and validate the data collected in the Spanish EURECCA (EUropean REgistry of Cancer CAre) Esophagogastric Cancer Registry between January 2014 and December 2017 through an audit process. It is also intended to describe the initiation and implementation of this Registry as well as its early outcomes. Methods. An audit of registered cases (esophageal, esophagogastric junction and gastric cancer resectable patients undergoing surgery) from 01/01/2014 to 12/31/2017 and a descriptive analysis of these data will be performed. Expected results. The study could show that the Spanish EURECCA Esophagogastric Cancer Registry is a reliable source of information, valid for carrying out specific and exhaustive analysis that may lead to high quality publications in indexed journals. It is also expected to generate a high impact based on the large number of cases included in the Registry, favoring new research projects. Relevance. The standardization of the data collection is essential to compare outcomes between different centers, regions and countries. This study will allows us to verify the integrity of the collected data as well as its accuracy, a critical aspect to gain credibility for future studies using the Registry data.

Gastric cancer (GC) is a leading global health problem and is the third most common cause of cancer related death. Neoadjuvant chemoradiotherapy (nCRT) followed by surgery is the mainstay treatment for locally advanced gastric cancer, and variable degrees of tumor regression are observed after nCRT. Treatment strategies, including close surveillance without immediate surgery, have been investigated to spare patients with complete tumor regression from potentially adverse outcomes of radical surgery. However, clinical and radiological assessment of treatment response does not deliver an ideal accuracy of patients identification with complete response. In the present study, we focused on the clinical courses of patients who have developed locally advanced gastric cancer, and investigated the potential clinical utility of the detection of deficient MMR(dMMR), microsatellite instability(MSI) status and the decreasing level of circulating tumor cells (CTCs) and circulating tumor DNA (ctDNA) as promising biomarkers for the diagnosis and prediction of GC during treatment progress. Twenty milliliters of plasma were collected at 3 time points: before nCRT; after 2 cycles of nCRT; and after surgery. Firefly ctDNA NGS assays were used to track ctDNA mutations previously characterized in paired tumor tissue by massively parallel sequencing (MPS). We investigated whether circulating tumor DNA (ctDNA) detection can reflect tumor response to nCRT and detect minimal residual disease(MRD) after surgery. We compared CTC and ctDNA levels to clinical, radiological and pathological assessment modalities for nCRT response. The results will provide lots of information which may contribute to promote the treatment of GC patients. We want to introduce these strategies into clinical practice if possible.
