Filter by:The aim of this study is to analyze whether COVID-19 causes a delay in the diagnosis of gastric cancer patients particularly in the TNM staging of the tumor, or not and to compare the number of newly diagnosed patients with gastric cancer before and during the COVID-19 pandemic period.
Gastric cancer is the fifth most common cancer worldwide. Gastrectomy with lymphadenectomy is still the most effective treatment modality, depending on the stage and location. Despite many radiological, surgical and anesthetic innovations, serious complications such as anastomotic leakage, intra-abdominal abscesses, wound complications are seen secondary to gastrectomy. Many clinical studies have been conducted to prevent and predict these complications. The Model for End-Stage Liver Disease (MELD) score, in which bilirubin, international normalized ratio (INR) and serum creatinine values were used to determine surgical risks in patients scheduled for liver transplantation. Latter developed by adding serum sodium (Na) to the formula. The MELD-Na score is used to predict postoperative complications in non-cirrhotic patients because of its simple and easy calculation.Moreover, The Meld-Na score was later used to predict complications for surgical procedures other than liver surgery such as colorectal surgery. In this study, we aimed to investigate the importance of the Meld-Na score in predicting the perioperative and postoperative outcomes in patients with gastric cancer.
To assess the role of docetaxel and irinotecan combination in second line gastric cancer. The primary end point is response rate. Secondary end points are toxicity, PFS and OS.
This clinical study is a Phase 2, open-label study to assess the efficacy, safety profile of FLX475 combined with pembrolizumab in patients with advanced or metastatic gastric cancer. This study is designed to assess the potential anti-tumor activity when administered at the 100mg QD of FLX475 with pembrolizumab and will be conducted (2) cohorts as detailed below. - Cohort 1: EBV negative / CPI naïve gastric cancer subjects who have progressed on at least 2 prior systemic treatments for advanced or metastatic gastric cancer - Cohort 2: EBV positive / CPI naïve gastric cancer subjects who had at least 1 prior systemic treatment for advanced or metastatic gastric cancer Approximately 90 subjects may be enrolled across two cohorts to examine the safety and efficacy.
Introduction: Traditionally, White Light Endoscopy (WLE), enhanced by biopsies following the updated Sydney system guidelines, has been the benchmark for diagnosing and classifying gastric preneoplastic conditions. Nevertheless, the pronounced interobserver variability and the often weak correlation between endoscopic observations and histopathological results have driven the increasing adoption of virtual chromoendoscopy (VCE). VCE technologies have demonstrated greater effectiveness in identifying these conditions compared to WLE, with Narrow Band Imaging (NBI) being particularly notable. Significantly, NBI has played a key role in validating the Endoscopic Grading of Gastric Intestinal Metaplasia (EGGIM) system. However, data on the effectiveness of other VCE technologies in this domain is relatively sparse in Europe, specifically with Blue Light Imaging (BLI), despite the promising diagnostic performance demonstrated with this technology. Primary aim: to assess the diagnostic accuracy of BLI and to externally validate the applicability of EGGIM classification for staging GIM. Material and methods: a multicentric cohort study will be performed involving centres from two European countries (Portugal, Italy). Consecutive patients performing upper gastrointestinal endoscopy will be evaluated by WLE and BLI. Random biopsies or targeted plus random biopsies will be performed in order to determine de accuracy of BLI system to detect and stage GIM. Expected results: We anticipate that BLI would enable us to assess the extension of GIM without the need for biopsies. If observed, this would overall improve the upper GI endoscopy accuracy.
Gastric cancer is one of the most common malignant tumors of the digestive tract. Gastric cancer patients diagnosed for the first time in China have a higher proportion of advanced stages and a higher postoperative metastasis rate.Studies have shown that patients with good pathological response after preoperative neoadjuvant therapy (such as tumor regression grade, TRG0 or 1) have a better prognosis.The purpose of this study is to treat patients with advanced gastric cancer who are difficult to perform R0 surgery with chemotherapy combined with immunotherapy. At the same time as the primary cancerous lesions are reduced, the distant metastatic lesions are effectively controlled in order to perform R0 surgery and to improve the survival rate of patients with advanced gastric cancer.
To observe the eradication rate of H. pylori infection, symptom improvement and the incidence of adverse effects in patients using a bismuth colloidal pectin granules quadruple therapy.
To explore the associations among bile acid profile, bile acid-microbiota cross-talk and the development of gastric cancer, so as to better prevent the occurrence and development of gastric cancer
This project aims to establish the safety and efficacy of treating patients with inoperable oesophageal cancer or gastric cancer, using an endoscopic electroporation system (EndoVE) to facilitate direct chemotherapy tumour absorption.
