Filter by:This clinical trial evaluates the usefulness of various risk assessment tests, including Helicobacter pylori (H. pylori) breath testing, questionnaires, and endoscopies for identifying participants at high risk for stomach cancer. H. pylori is a bacteria that causes stomach inflammation and ulcers in the stomach. People with H. pylori infections may be more likely to develop cancer in the stomach. H. pylori breath testing can help identify the presence of H. pylori infection in a participant and help identify if the participant may be at a higher risk of developing stomach cancer. An endoscopy uses a thin, flexible lighted tube that is inserted inside the esophagus, stomach, and first part of the small intestine. This allows the doctor to see and look for abnormal areas that may need to be biopsied. Risk assessment including H. pylori evaluation, questionnaires, and endoscopies may help identify participants at high risk for stomach cancer and may be a useful screening tool for earlier stomach cancer diagnosis.
We plan to initiate a prospective, multicenter, randomized, double-blind, placebo-controlled phase II study, recruiting 198 patients with advanced gastric/gastroesophageal junction adenocarcinoma who have not received prior treatment. Randomly divided into two groups, one group is the group of fecal microbiota transplantation(FMT)+SOX+Sintilimab, and the other group is the group of SOX+Sintilimab. Compare the 2-year OS rates of the two groups to verify whether the addition of FMT to first-line treatment can improve the prognosis of gastric cancer patients.
A complete omentectomy is typically recommended during radical total gastrectomy for gastric cancer, though its impact on survival remains unclear. This study aimed to assess the frequency and risk factors of metastases in the greater omentum in gastric cancer patients undergoing gastrectomy. It will involve a single prospective cohort of consecutive patients who underwent total gastrectomy with complete en bloc omentectomy and modified D2 lymphadenectomy. Post-surgery, the omentum will dissect from the gastrectomy specimen beyond the gastroepiploic vessels and examine separately for pathological assessment. The primary outcome will focus on the detection of omental metastases.
In this study, investigators utilize a radiopathomics integrated Artificial Intelligence (AI) supportive system to predict tumor response to neoadjuvant chemoradiotherapy (nCRT) before its administration for patients with locally advanced gastric cancer (LAGC). By the system, the postoperative tumor regression grade (TRG) of the participants will be identified based on the radiopathomics features extracted from the pre-nCRT Enhanced CT and biopsy images. The ability to predict TRG will be validated in this multicenter, prospective clinical study.
The KOrean QUality of life in Stomach cancer patients Study group (KOQUSS) made a method (KOQUSS-40) for assessing appropriately the quality of life of gastric cancer patients who have undergone gastrectomy, and developed a digital platform (Wecare) based on KOQUSS-40. In this study, we propose a randomized controlled trial to compare quality of life after gastrectomy in patients with and without smartphone app support.
This study aims to develop and validate a Random Survival Forest (RSF) model for predicting long-term survival in elderly patients following curative resection for gastric cancer. The study is a retrospective multi-center analysis involving patients aged 75 and above who underwent gastric resection from January 2009 to December 2018 at nine top-tier hospitals in China. An online prognostic tool is introduced to assist clinicians in predicting patient prognosis and customizing treatment and follow-up strategies.
Background：Gastric cancer is a globally important disease and the fifth most diagnosed malignant cancer in the world. Because it is usually diagnosed at an advanced stage, gastric cancer has a high mortality rate, making it the third most common cause of cancer-related death. Hot spots of gastric cancer incidence and mortality exist in East Asia, Eastern Europe and South America. It is still an urgent problem to find new diagnostic and prognostic markers and better understand the molecular mechanism of gastric cancer. Although radical resection and systemic chemotherapy have shown great improvement, the prognosis of gastric cancer (GC) patients is still depressing due to malignant proliferation and metastasis. Therefore, it is urgent to clarify the potential molecular mechanism of gastric cancer progression, which will contribute to the development of targeted therapy. Effective induction of tumor cell apoptosis is the most important feature of a new chemical agent for cancer treatment. There is increasing evidence that the cell cycle can act in concert with apoptosis to cause cell death under certain cellular stress conditions. A comprehensive understanding of the relationship between apoptosis and cell cycle is essential for developing effective cancer therapies. PWP1 is also known as endonuclein, which contains five WD40 repeated domains and belongs to the WD40-repeated superfamily. It is highly expressed in human pancreatic adenocarcinoma, where it functions as a cell-cycle regulator. However, the normal function of Pwp1 is largely unknown. Previous research data show that PWP1 plays a key role in regulating biological functions such as RNA processing, signal transduction, gene expression, vesicle transport, cytoskeleton assembly and cell cycle progression. Whether the high expression of PWP1 is ubiquitous in tumors, the relationship between the high expression and clinicopathological factors of tumors, and the mechanism of PWP1 in tumors are still unclear. Further exploration of the molecular mechanism of PWP1 in GC may provide new ideas and therapeutic targets for GC treatment in the future, and benefit clinical patients.
To evaluate the diagnostic performance of blood-based SPOT-MAS test in symptomatic individuals, we sought to launch a prospective multicenter study, named K-ACCELERATE. The study aims to recruit 1,000 participants who develop symptoms and signs specific to the top five common cancer types including breast, colorectal, gastric, liver and lung cancer. Primary objective: Evaluate the performance of the SPOT-MAS test in detecting cancer in symptomatic populations. Secondary objectives: Evaluate the feasibility of incorporating SPOT-MAS as a triage test into primary care to increase the detection rates of malignant cancer while minimizing unnecessary referrals to invasive procedures.
This is a prospective multicenter comparative study, aiming to compare probe-based confocal laser endomicroscopy (pCLE) and endoscopic biopsies in the diagnosis of the whole specific gastric lesion especially for distinguishing low grade intraepithelial neoplasia (LGIN) from high grade intraepithelial neoplasia (HGIN) and create an endoscopic image database for the follow-up research.
This study is a prospective, open-label, phase II clinical trial that aims to enroll patients with locally advanced gastric adenocarcinoma who have not received any prior treatment and are candidates for surgery. The study drugs include RC48, Adebrelimab, Apatinib and S-1. The purpose is to evaluate the effectiveness and safety of the combined coordinated treatment of multi-mechanism drugs for perioperative treatment of locally advanced gastric cancer with HER2 overexpression.
