Filter by:The purpose of this study is to collect and evaluate real-world data to enhance understanding of the effectiveness, and treatment patterns of first-line nivolumab treatment in patients with unresectable advanced or metastatic gastric cancer/gastroesophageal junction cancer (GC/GEJC) in China
The aim of this study to validate the role of pepsinogens in gastric cancer screening.
To explore the effect of adjuvant chemotherapy cycles on the prognosis of this specific patient with lymph node-negative gastric cancer following neoadjuvant chemotherapy.
The overall aim is to utilize multi-omics approach to identify novel etiopathogenesis and early detection biomarkers for stomach cancer precursor lesions. To achieve this aim, first the investigators will use stored serum samples to perform metabolomics profiling among 12,599 twin subjects, among whom 1034 were deemed to have chronic atrophic gastritis based on measured pepsinogen I and II levels. Logistic regression will be used to search for metabolites related to the risk of chronic atrophic gastritis. Second, the investigators will further measure serum proteome by using two quantitatively precise proteomics assays, among the above-mentioned twin subjects. Identified protein biomarkers will be combined with metabolomics biomarkers to create a prediction model for chronic atrophic gastritis. The results will hopefully improve our understanding of the etiological factors and provide promising early detection biomarkers for stomach cancer precursor lesions.
Medical advancements are enhancing the survival rates of individuals with gastric cancer. The growing population of gastric cancer survivors underscores the importance of managing treatment-related after-effects and side effects. Diminished physical function in cancer patients, particularly following gastric cancer surgery, is linked to increased mortality. The substantial decline in physical activity post-surgery contributes to a notable reduction in cardiorespiratory fitness and lower extremity muscle strength. Early postoperative exercise has demonstrated positive outcomes in colorectal cancer patients, facilitating early hospital discharge and supporting long-term recovery. However, there is a paucity of research on the efficacy of early postoperative exercise in the context of gastric cancer. Therefore, this study aims to evaluate the impact of early postoperative exercise on physical function following gastric cancer surgery.
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.
To evaluate the safety and effectiveness of laparoscopic gastrectomy (LG) following neoadjuvant immunochemotherapy (nICT)
The investigators aimed to clarify the clinical relevance of the ERAS protocol by evaluating the perioperative course in patients undergoing laparoscopic gastric cancer surgery.
We envisioned a scenario where the interaction between the ATM-Chk2/ATR-Chk1 pathways and Hippo enables GC cells to overcome chemotherapy-induced death stimuli. First, ATM-Chk2 and ATR-Chk1 were found to be activated across all the GC molecular subtypes. Moreover, a number of genes associated with their basal activation are recurrently mutated or amplified. Thus, we retrospectively characterized a cohort of GC patients treated with first-line therapy for DDR- and Hippo-related markers, identifying a signature predicting inferior PFS and OS. This exploratory analysis provided the necessary information (frequency of candidate biomarkers and effect difference between groups) for a prospective study with validation purposes, which is the main goal of this trial.
In the study, the investigators obtained gastric cancer tissues from 480 gastric cancer patients who had undergone surgery at the Zhejiang Cancer Hospital's biospecimen bank between 2012-2019, and obtained relevant clinical information. The gastric cancer tissues were subjected to transcriptomic, metabolomic and other multi-omics testing, and analyzed for the metabolic changes of gastric cancer, and proposed to discover relevant therapeutic targets.
