Filter by:Study the correlation between in vitro drug sensitivity screening of digestive tract tumor organoids and their clinical efficacy in anti-tumor treatment, evaluate the use of digestive tract tumor organoid drug sensitivity to predict the therapeutic effect of anti-tumor drugs, and explore new methods for personalized and precise treatment of esophageal cancer, gastric cancer, colorectal cancer, and gastrointestinal stromal tumors.
This will be a longitudinal, prospective, observational multicenter study where the role of EUS-E will be examined in differentiating subepithelial gastrointestinal tumors in 138 patients
This is a single-arm, prospective, exploratory clinical study to evaluate the efficacy and safety of endostar combined with stereotactic body radiation therapy (SBRT) and Envafolimab in patients with advanced gastrointestinal cancer after multi-line treatment.
This is a multicenter, open-label, prospective Phase 1/2a study to assess safety and tolerability, establish dosimetry and to identify an optimal imaging dose (radioactivity and mass dose) and imaging time window of 64Cu-LNTH-1363S (64Cu Radiolabeled FAPi PET/CT Imaging Agent) and to compare its imaging biodistribution with FAP expression by immunohistochemistry (IHC) in patients with sarcomas or GIT cancers. The study will be conducted in 2 parts (Part 1 and Part 2).
The goal of this observational study is to examine genetic changes that may contribute to immunotherapy resistance in gastroesophageal cancer. This information can potentially lead to the identification of new immunotherapeutic targets as well as improve the ability to identify those patients more likely to respond to immunotherapy. This study does not include any treatment or investigational drugs. Participants will be asked: - to enroll before beginning standard care of treatment for their cancer - for blood, archived tumor tissue, and fresh tumor tissue Researchers will compare participants who are not getting immunotherapy to identify potential differences in expression levels of a gene.
Recent studies show an increase in neuroendocrine neoplasms, especially for the digestive tract. Previous studies suggest various risk factors that were observed for various tumor sites, e.g. a family history of cancer, tobacco and alcohol consumption as well as metabolic disorders including diabetes and obesity. A risk factor that has been little studied to date is depressive disorders, which could increase the risk of neuroendocrine neoplasms either independently or through associated risk behaviors and/or antidepressant medication. The aim of this study is to identify risk factors for neuroendocrine neoplasms based on a case-control study in order to better understand the increase of neuroendocrine neoplasms in recent decades. The study is based on a record linkage of data from the Bavarian Cancer Registry and data from the Bavarian Association of Statutory Health Insurance Accredited Physicians. While the data from the Bavarian Cancer Registry enables the identification of neuroendocrine neoplasms on the basis of histopathological findings and thus is the basis for selecting cases, the claims data from the Bavarian Association of Statutory Health Insurance Accredited Physicians provides the source population as well data on diagnoses and thus enables the investigation of risk factors.
This study constitutes a case-control investigation employing a retrospective approach. Plasma samples from individuals with esophageal cancer, benign esophageal diseases, gastric cancer, benign gastric diseases, and a healthy control group were systematically collected. Advanced Data-Independent Acquisition (DIA) proteomics and single-vesicle membrane protein detection techniques were employed to quantify protein content within exosomes. Specific protein biomarkers indicative of early-stage upper gastrointestinal tumors were identified. External validation of these protein markers was conducted using Parallel Reaction Monitoring (PRM) technology on an independent validation cohort. The objective is to establish protein marker predictions for early diagnosis of upper gastrointestinal tumors and prognostication of therapeutic efficacy.
The goal of this clinical trial is to assess the effectiveness and safety of non-dressing (exposed wound) versus dressing techniques in postoperative wound management for patients with gastrointestinal tumors. The main questions it aims to answer are: 1. Does non-dressing of postoperative wounds in gastrointestinal tumor surgery provide equivalent or better wound healing compared to traditional dressing techniques? 2. Can non-dressing of postoperative wounds reduce patient pain and healthcare costs? Participants in this study, who are diagnosed with gastrointestinal tumors and undergoing surgery, will be randomly assigned to either the non-dressing group or the dressing group. The non-dressing group will have their surgical wounds left exposed after initial postoperative care, while the dressing group will receive regular wound dressing changes every 48-72 hours. Researchers will compare these two groups to see if there are differences in the rate of wound complications, pain levels, and overall healthcare costs. This study aims to provide evidence-based recommendations for postoperative wound care in gastrointestinal tumor surgeries, potentially improving patient outcomes and reducing medical expenses.
This research study is being conducted to improve the quality of care of participants who have a diagnosis of gastrointestinal cancer (anal, colon, rectal, esophageal, stomach, small bowel, appendix, pancreas, gall bladder, liver, neuroendocrine tumor of gastrointestinal origin). This study has 3 components as follows- 1. Ensuring appropriate biomarker testing and evidence-based care: Biomarkers are molecules in the tumor or blood that indicate normal or abnormal processes in participant's body and may indicate an underlying condition or disease. Various molecules, such as DNA (genes), proteins, or hormones, can serve as biomarkers since they all indicate something about participant's health. Biomarker testing can also help choose participant's treatment. Additionally, a tumor board will be conducted periodically to provide treatment recommendations to participant's treating physician. Participants will receive standard-of-care treatment if participant enroll in this study. Participant will not receive any experimental treatment. 2. Assistance with clinical trial enrollment. The study team will help participants enroll in a clinical trial appropriate for participant's condition. However, enrolling in a clinical trial is totally up to the participant. 3. Health literacy: The study team will provide information relevant to participant's diagnosis to enrich participant's understanding of participant's condition and treatment. Investigator will provide questionnaires to assess participant's understanding before and after participant's have been provided with educational/informational material appropriate for participant's diagnosis.
The goal of this clinical trial is to evaluate the effectiveness of intraoperative intermittent pneumatic compression (IPC) device usage in preventing lower extremity deep vein thrombosis (DVT) in patients undergoing gastrointestinal surgery.The main question it aims to answer is provide a reference basis for determining the efficacy of IPC application during gastrointestinal surgery for preventing lower extremity DVT in patients. Participants are patients who require gastrointestinal surgery, specifically for the resection of gastrointestinal tumors. They will be divided into a control group and an experimental group. The experimental group will use an Intermittent Pneumatic Compression (IPC) device during surgery, while the control group will receive standard treatment. The objective is to observe whether the use of IPC during surgery can prevent the formation of Deep Vein Thrombosis (DVT) or lower the Risk of DVT.
