Filter by:This is a single center, case-control, diagnostic study.The aim of this study is to use deep learning methods to retrospectively analyze the imaging data of gastrointestinal endoscopy in Qilu Hospital, and construct an artificial intelligence model based on endoscopic images for detecting and determining the depth of invasion of esophagogastric junctional adenocarcinoma.This study will also compare the established AI model with the diagnostic results of endoscopists to evaluate the clinical auxiliary value of the model for endoscopists.The research includes stages such as data collection and preprocessing, artificial intelligence model development, model testing and evaluation. The gastroscopy image dataset constructed by this research institute mainly includes three modes of endoscopic imaging: white light endoscopy, optical enhancement endoscopy (OE), and narrowband imaging endoscopy (NBI).
This is an observational study with a case control design. This study included patients with gastric cancer confirmed by pathological diagnosis of gastric tissue, and matched the control population according to age, gender, etc. In this study, researchers collected clinical information and multiple biological samples such as saliva, serum, and feces from the study subjects. We combined 16S rRNA sequencing and metabolomics to explore the differences in microbial and metabolic characteristics between gastric cardia cancer and non-cardia gastric cancer for early screening of gastric cancer.
The goal of this cross-sectional study is to evaluate epigenetic modifications in gastric carcinogenesis, mainly in H. pylori gastritis vs gastric carcinoma. The main question[s] it aims to answer are: - How does H. pylori infection cause gastric cancer? - Can DNA methylation and other epigenetic changes predict and affect the development of gastric cancer? Formalin-fixed-paraffin-embedded tissue specimens will be obtained and reviewed for comparison between epigenetic changes in H. pylori gastritis and gastric adenocarcinoma.
This trial is an open-label, multicenter, first-in-human dose-escalation and cohort expansion Phase I/II clinical study to evaluate the safety, tolerability and preliminary efficacy of IMM2902 in the treatment of HER2-expressing advanced solid tumors
To determine the long term outcomes of Endoscopic Submucosal Dissection (ESD), Endoscopic Full Thickness Resection (EFTR) and Submucosal-Tunnelling Endoscopic Resection (STER) for upper gastrointestinal neoplastic lesions
This phase Ib trial test effects of aldesleukin in combination with nivolumab and standard chemotherapy in treating patients with gastric cancer that has spread to the tissue lining of the abdomen (peritoneal metastasis). Aldesleukin is similar to a protein that naturally exists in the body that stimulates the immune system to fight infections. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as leucovorin calcium, fluorouracil, and oxaliplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving aldesleukin in combination with nivolumab and standard chemotherapy may work better in treating patients with gastric cancer with peritoneal metastasis.
- 1. Main objective: to evaluate the pathological complete response (pCR) of gastric cancer after local advanced COVID-19 infection by two kinds of immunotherapy combined with Anlotinib Hydrochloride Capsules and neoadjuvant chemotherapy. - 2. Secondary objective: to evaluate the major pathological response (MPR), disease-free survival (DFS), objective response rate (ORR), R0 resection rate (R0 resection rate) and safety of two kinds of immunotherapy combined with Anlotinib Hydrochloride Capsules and neoadjuvant chemotherapy for gastric cancer after local advanced COVID-19 infection。
The goal of this clinical trial is to explore the efficacy and safety in patients with gastric adenocarcinoma or adenocarcinoma of esophagogastric junction. The main questions it aims to answer are: - Does this therapy have a promising efficacy? - Does this therapy have a manageable toxicity? Participants will receive fruquintinib plus sintilimab as first-line therapy for gastric cancer.
In this study, the investigators evaluate the effect of total intravenous anesthesia using sufentanil-remimazolam and remifentanil-remimazolam on postoperative pain in patients undergoing laparoscopic gastrectomy.
This study is carried out to find out if a customized molecular test can identify a subgroup of patients with very-high-risk of developing stomach cancer within patients with intestinal metaplasia (IM). The investigators hypothesise that the incidence of dysplasia and GC cases in the molecular-test-positive group will be significantly higher than that in the molecular-test-negative group. Such a test has the potential to guide clinicians to better manage patients with IM by allowing endoscopic surveillance to be focused on individuals at very-high-risk of developing stomach cancer, at the same time avoiding or reducing endoscopies for those at lower risk.
