Filter by:Upper gastrointestinal (GI) cancers are one of the most common cancers worldwide. Except for cardia cancers, the incidence of gastric cancer has decreased consistently since 1980, but remains at a high level. In France, gastric cancers are the 6th most common cause of cancer-related mortality. The risk factors of upper GI cancers are well known and their control could prevent the development of cancers: smoking cessation, reduction of obesity, alcohol, eradication of Helicobacter pylori. But late presentation with upper GI cancer results in a poorer prognosis. Patients with advanced (Stage IV) gastric cancer have a five-year survival rate of 3.7% whereas patients whose gastric cancer is discovered in its early stage (Stage I) have a significantly higher five-year survival rate of 88.4%. Therefore, endoscopic detection of upper GI lesions at an earlier stage is the single most effective measure for reducing cancer mortality. But upper GI cancer is also often missed during examinations, and some studies demonstrated a missed cancer rate of 2.3-13.9% in Western populations. In the past decade, accurate diagnosis during endoscopy has become particularly important as dysplastic lesions and early gastric cancers can be treated effectively with both endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD), avoiding the morbidity and mortality associated with gastrectomy. However, these early neoplastic lesions can be sometimes difficult to distinguish from background mucosa, even with advanced imaging techniques (high definition, chromoendoscopy). In recent years, image recognition using artificial intelligence (AI) with deep learning has dramatically improved and opened the door to more detailed image analysis and real time application in various medical field, including endoscopy. For example, in the colorectal cancer screening area, real time computer-aided detection systems (CADe) can lead to significant increases in both polyp and adenoma detection rates. CADe has also shown good performance in detection of Barrett's neoplasia during live endoscopic procedures in order to more accurately locate the area to be biopsied. Recently, a Chinese study showed that CADe achieved high diagnostic accuracy in detecting upper GI cancers, with sensitivity similar to that of expert endoscopists and superior to that of non-experts. This system could support non-experts by improving their diagnostic accuracy to a level similar to that of experts and provide assistance for improving the effectiveness of upper GI cancer diagnosis and screening. Although encouraging results have been published regarding the use of AI in the diagnosis of upper GI cancers, the clinical applicability of such systems in a European population has yet to be investigated. Therefore, we want to evaluate the diagnostic capability of a recent CADx compared to endoscopists in order to improve the real-time detection of early gastric cancers in our European center Edouard Herriot Hospital, Lyon, France, as well as 3 other tertiary centers in France (Limoges, Rennes and Nancy University Hospitals). With a high prevalence of stomach cancer, Japan is a world leader in high-quality diagnostic upper GI endoscopy, and the clinical routine in this country differs substantially from Western practice, with population-based screening programs. We will use for our study a CADx developed by AI medical service Inc. (1-18-1, Higashiikebukuro, Toshima-ku, Tokyo 170-0013, Japan), a Japanese company developing AI systems that supports endoscopist's diagnosis for the digestive tract. A recent study involving AI medical service system showed good results in the diagnosis of early gastric cancer compared to endoscopists, with a significantly higher sensitivity.
Currently, there is no Brazilian or Latin American epidemiological data, such as clinical-pathological characteristics, standard treatments and outcomes of gastric cancer and pancreatic cancer in the region. The study aims to create a Latin American multicenter database to analyze epidemiological, clinical, and pathological data, treatments, outcomes, and biological information from patients with gastric and pancreatic cancer.
The goal of this clinical trial is to determine if FOG-001 is safe and effective in participants with locally advanced or metastatic cancer.
This is a randomized, controlled, multicenter phase Ⅲ study to evaluate the therapeutic efficacy of modified XELOX plus sintilimab versus standard XELOX plus sintilimab in subjects with advanced HER2-negative gastric or gastroesophageal adenocarcinoma in the first-line treatment. The primary outcome is the progression-free survival (PFS), with a planned enrollment of 540 subjects.
To investigate the clinical efficacy and safety of envollizumab combined with fruquintinib and SOX versus SOX in conversion therapy for patients with Her-2 negative, unresectable locally advanced gastric cancer.
Background: Surgery can significantly improve the prognosis of patients with gastric cancer. However, some patients are at a later stage at diagnosis and need to receive neoadjuvant chemotherapy (NACT). Previous studies have shown that NACT may lead to more postoperative complications. Probiotics have the potential to reduce postoperative complications and infections, but no large sample, multicentre, randomized clinical trials have been conducted in patients with gastric cancer receiving NACT. The aim of this multicentre randomized controlled trial was to investigate the effect of probiotics on postoperative infections and other short-term outcomes in patients with gastric cancer receiving NACT. Methods/design: This study is a prospective, multicentre RCT. This experiment will consist of two groups - an experimental group and a control group - randomly divided in a 1:1 ratio. The experimental group will receive perioperative probiotic supplement and that of the control group will receive blank control management. An estimated 318 patients will be enrolled. The main endpoint for comparison is postoperative infections between the two groups.The experimental group patients received probiotic capsules containing Bifidobacterium longum, Lactobacillus acidophilus, and Enterococcus faecalis.
The goal of this observational study is to compare specific microRNA levels from the plasma of gastric cancer patients and healthy volunteers to see if there is an upregulated expression in gastric cancer patients. The main question it aims to answer is: - Can microRNAs be effectively used as diagnostic biomarkers for gastric cancer? Participants will be asked for their consent to obtain 5 cc of blood.
This is a multi-centre, partially blinded, side-by-side comparator study to assess the safety and tolerability, feasibility, and potential added diagnostic and clinical value of using the FerroTrace® and FerroMag Sentinel Lymph Node Mapping (SLNM) System for mapping sentinel lymph nodes (SLNs) in subjects with gastric, gastric-oesophageal junction, and oesophageal cancers, consisting of a safety lead-in phase and an expansion phase.
Twenty (n=20) patients with gastric cancer or gastro-esophageal junctional cancer will undergo FAPI PET/CTs in addition to routing diagnostic workup (including FDG PET/CT) at primary staging and restaging. The FAPI PET/CT results will be compared to conventional imaging (including FDG PET/CT) using histopathology as reference standard, and the diagnostic accuracy will be determined. FAP-immunohistochemistry will be conducted in surgical specimens. FAPI PET/CT's impact on patient management and the prognostic value of FAPI PET/CT will be evaluated.
This is a Phase Ib/II study to identify the RP2D of T-DXd combination with Ram and to assess the safety and clinical efficacy of this combined treatment in advanced gastric cancer after first-line treatment. The study will be conducted in two parts: Phase Ib dose escalation study to determine the MTD and RP2D of T-DXd combination and Ram, and Phase II to further evaluate the safety and tolerability of T-DXd combinations with Ram at the RP2D and determine anti-tumor activity.
