Filter by:A multicenter Italian retrospective study on COVID-19 pandemic condition and advanced Gastro - Intestinal Cancer. Are in Italy increased the new diagnosis of GI cancer in advanced stage in the 2020 compared with 2019, as a consequence of COVID-19?
Prospective observational study comparing calcium and sodium levofolinate in combination with 5FU/or in FOLFIRI regimen on patients affected by gastrointestinal cancer (any site of disease along with gastrointestinal tract) who have been prescribed FOLFIRI in standard clinical practice.
Deep learning technology has an increasing role in medical image applications and, recently, an artificial intelligence device has been developed and commercialized by Medtronic for identification of polyps during colonoscopy (GI-GENIUS). This kind of computer-aided detection (CADe) devices have demonstrated its ability for improving polyp detection rate (PDR) and the adenoma detection rate (ADR). However, this increase in PDR and ADR is mainly made at the expense of small polyps and non advanced adenomas. Colonoscopies after a positive fecal immunochemical test (FIT) could be the scenario with a higher prevalence of advanced lesions which could be the ideal situation for demonstrating if these CADe systems are able also to increase the detection of advanced lesions and which kind of advanced lesions are these systems able to detect. The CADILLAC study will randomize individuals within the population-based Spanish colorectal cancer screening program to receive a colonoscopy where the endoscopist is assisted by the GI-GENIUS device or to receive a standard colonoscopy. If our results are positive, that could suppose a big step forward for CADe devices, in terms of definitive demonstration of being of help for efectively identify also advanced lesions.
This is a pilot study aiming to investigate the ability of a novel Optical Coherence Tomography (OCT) probe in assessing the different layers of the gastrointestinal tract and the depth of invasion of early neoplasia, utilising surgically and endoscopically resected specimens
The purpose of this study is to learn about the impact of the Oncology Nurse Navigation program on the frequency of Emergency Department, urgent care visits and inpatient hospital admissions; and overall survival rate at 6 months. The investigators aim to understand if prompt and effective coordination of care provided by Oncology Nurse Navigation (ONN) service will reduce the number of avoidable, unplanned ED visits and hospitalizations, as well as adding measurable value to cancer care, and improve patient overall survival.
This multicenter, prospective, interventional study aims to include 2000 gastroscopic procedures and investigate the relationship between procedure time and lesion detection rate in tertiary endoscopic centers in China. At the first stage, the researchers observe the actual procedure time of gastroscopies without affecting the natural behavior of endoscopists. At the second stage, a minimal time limit will be set for each procedure based on the observational results of the first stage. The primary study outcome is focal lesion detection rate. Secondary outcomes include detection rate of early upper GI cancer, biopsy rate and adverse event rate.
Colorectal cancers are the third most common cancer in the world. In advanced stages of colorectal cancers, peritoneal carcinomatosis and intraabdominal acid development occur. Although stomach cancer is the 5th most common cancer in the world, it is the third cancer with the highest mortality. Pancreatic cancer is one of the highest mortality cancers worldwide. Likewise, in advanced stages of stomach and pancreatic cancer, peritoneal carcinomatosis and intra- abdominal acid development occur. It is known that the immune system plays an important role in tumor development or destruction of tumor. Recent studies have shown that tumor cells develop escape mechanisms in the tumor microenvironment to escape from host immunity. It has been reported that differentiation of T cells towards Th2 and regulatory T cells is also effective in tumor progression(6). Changes in the tumor microenvironment and immune checkpoints are important mechanisms that lead to escape from the immune system. Immune checkpoints are on the agenda especially after 2018 Nobel Prize and they are important molecules in revealing the relationship.In our study, it is aimed to evaluate whether there is a difference in immune control points in patients with end-stage colorectal cancer, gastric cancer and pancreatic cancer compared to patients without malignancy, and the relationship of these parameters with patient survival and tumor spread mechanisms.
A prospective, multi-center, open label, study to evaluate safety and performance of Seal-G and Seal-G MIST in reinforcing colonic anastomosis, in subjects undergoing Colon Resection surgery
This phase I trial collects blood samples to investigate the prevalence of changes in genes (genetic mutations) in solid tumor patient populations seeking care at Mayo Clinic Embedded Cancer Center at St. Vincent's Riverside. This may help doctors better understand and/or treat others who have genetic mutations.
This study is a prospective study where the investigators will make a database of all the patients who have received this procedure and will document various outcomes (i.e. number of sutures used, number of clips (if used), time required to close, complications/ issues). No changes will be done to the participant's procedure and the participants are asked to consent for the use of the participant's data in our database. The participants are being asked to be in this research study because the participants have been scheduled to undergo an ESD procedure at Baylor St. Luke Medical Center and will most likely require clipping and/or suturing following intervention. This study is important because this is a relatively new procedure; although it is a part of the participant's standard of care, it is not done in many hospitals. The investigators would like to document the outcomes and results of such procedures to continuously improve our standard of care.
