Filter by:This study aims to develop and validate a Nomogram (mCNS) model for predicting long-term survival in elderly patients following curative resection for advanced gastric cancer. The study is a retrospective multi-center analysis involving 924 gastric cancer patients treated at the Department of Gastrointestinal Surgery of the Affiliated Union Hospital of Fujian Medical University between 2009 and 2013, and 512 patients aged 65 and above who underwent gastric resection at the Affiliated Zhongshan Hospital of Dalian University between 2011 and 2018. An online prognostic tool is introduced to assist clinicians in predicting patient prognosis and customizing treatment and follow-up strategies.
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.
Extensive research employing diverse omics methodologies has unveiled a varied landscape of gastric cancer (GC). Recent progress in next-generation sequencing and other genomic technologies has facilitated a more intricate exploration of GC at the molecular level. This study aimed to identify the most effective drug therapeutics for patients with the mesenchymal subtype of gastric cancer.Based on RNA-seq transcriptome, 234 patients were divided into four molecular subtypes: mesenchymal, immunogenic, metabolic, and classic.Our analysis has revealed that, for neoadjuvant therapy in advanced gastric cancer (AGC), the mesenchymal subtype stands out as the ideal patient population benefiting from Apatinib, without a concurrent increase in postoperative complications.
Background: Gastric cancer patients receiving neoadjuvant chemotherapy (NACT) are more vulnerable to perioperative stress. Enhanced recovery after surgery (ERAS) is widely used in surgical patients aiming at reducing stress responses. However, whether this approach is safe and feasible for gastric cancer patients received minimally invasive radical gastrectomy after NACT remained determined. So, the objective of this study is to investigate the effects of ERAS for this special group of gastric cancer patients. Materials and Methods: The data of gastric cancer patients who underwent minimally invasive radical gastrectomy after NACT were collected in this retrospective cohort study. Patients were divided into an ERAS group and a conventional group based on whether they received perioperative ERAS management. Propensity score matching was conducted to eliminate bias. Pre- and postoperative inflammatory and nutritional marker levels, postoperative complications, recovery indices and 3-year OS and RFS were observed.
The Systemic Oxidative Stress Score (SOSS) , a comprehensive score reflecting the oxidative stress conditions in the microenvironment, can independently and effectively predict tumor burden and long-term prognosis in GC patients. Nomograms based on SOSS provide a potential and promising model for risk stratification and guiding the implementation of treatment decisions.
The purpose of this clinical trial is to prove that the prediction capability of 'WAYMED endo' is superior to that of the endoscopists in classifying EGC based on the depth of invasion categories in gastro-endoscopic images. The computer-aided detection·diagnosis software is an Artificial Intelligence (AI) software used to assist medical specialists in diagnostic decisions by automatically classifying EGC based on the depth of invasion categories in gastro-endoscopic images and displaying the results and possibilities on the User Interface (UI).
To explore the effects of gastric xanthoma on gastric cancer and its precancerous lesions, so as to better prevent the occurrence and development of gastric cancer.
Objective: To define complete mesogastric excision and compare our short term results for the first time in a different population. Study design:Randomised-controlled study Place and duration of the study: Gastroenterological Surgery Clinic,Health Sciences University,Basaksehir City Hospital,Istanbul,Turkey,from April to December 2023. Methodology: We compared short term results of open total gastrectomy+ mesogastrectomy with standard total gastrectomy + D2 lymph node dissection at a tertiary center in terms of peroperative results, histopathological findings and postoperative short- term outcomes with review of the literature. Conclusion: Our aim is to show that mesogastric excision is safe and has advantages over conventional D2 gastrectomy in means of not only peroperative and short-term outcomes, but also disease free survival.Our work is the first study from a different population of the world and our initial results can contribute to the literature for universalization.
The objective of this randomized controlled, prospective clinical study, composed of 5 groups, G1, G2, G3, G4 and G5 is [Evaluate the intestinal microbiota profile, nutritional, immunological status and inflammatory profile, before and after total or partial removal surgery (gastrectomies) for gastric cancer, in a patient using probiotic supplements.] The main questions it aims to answer are: - probiotics are capable of modulating the immune response and microbiota in cancer patients who will undergo surgery - surgery itself alters the immunological pattern and microbiota of cancer patients Participants will be divided into groups for evaluation and the G1 intervention group will take probiotic capsules. The researchers will compare groups G1, G2 with G3 (negative control group) to see if there are differences between using probiotics or not, in controlling the immune response and if there are significant changes in their intestinal microbiota. Groups G4 and G5 will also be compared, where in these we will only measure the power of the use of probiotics in reducing surgical complications in the postoperative period.
