Chemoradiotherapy and SHR-1701 in Patients With Unresectable Gastric Cancer

Gastric Cancer is one of the leading causes of cancer-related death worldwide, and patients with unresectable locally advanced or metastatic disease have a poor prognosis. This study aims to evaluate the safety and efficacy of radiotherapy combined with CAPOX and SHR-1701, a PD-L1/TGF-β bispecific antibody, in patients with unresectable locally advanced or metastatic gastric or gastroesophageal junction adenocarcinoma. By improving local tumor control and enhancing systemic antitumor activity, this study seeks to increase the opportunity for curative-intent resection and improve survival outcomes in patients with advance gastric cancer.

A Noninvasive and Screening miRNA Signature for Gastrointestinal Cancer

Gastrointestinal (GI) cancers remain a major global health burden, largely due to the lack of effective and accessible early screening strategies. Current diagnostic approaches-including endoscopy, computed tomography (CT), and magnetic resonance imaging (MRI)-are either invasive, resource-intensive, or insufficiently sensitive for detecting early-stage disease, and are therefore not suitable for population-wide screening or for simultaneously identifying multiple GI tumor types. As a result, many patients are diagnosed at advanced stages, when therapeutic options are limited and prognosis is poor. Circulating microRNAs (miRNAs) offer a promising alternative, as they are stable in peripheral blood and reflect tumor-related molecular alterations. In this study, the investigators aim to develop and validate a robust, noninvasive miRNA-based signature capable of distinguishing GI cancers from non-malignant controls. By integrating multi-cohort datasets and applying machine learning-based feature selection and predictive modeling, the investigators will construct a screening panel optimized for reproducibility, scalability, and early-stage detection. This noninvasive miRNA signature has the potential to support accessible, cost-effective, and clinically practical population-level screening for GI cancers, ultimately facilitating earlier diagnosis and improving outcomes for participants.

A Phase 1, First-in-human Study of OKN4395 and Pembrolizumab in Patients With Solid Tumors

The purpose of this study is to investigate the study drug, OKN4395, administered alone and in combination with pembrolizumab. The overall objectives of this study are to determine the safety and tolerability (degree to which side effects of a drug can be tolerated) of OKN4395 alone and in combination with pembrolizumab, OKN4395 and metabolites (broken-down substances) of OKN4395 levels in the blood, and antitumor activity of OKN4395 alone and in combination with pembrolizumab. This study will be split into 2 parts. Part 1a will look at multiple doses of OKN4395 either alone (monotherapy) or with pembrolizumab (combination therapy) administered on day 1 of each 21-day cycle in patients with solid tumors until the participant has disease progression or discontinues for any reason. The dose of OKN4395 will be increased, after each group of 3 or more participants completes their first 3 weeks of treatment and their data is evaluated for safety, with a planned dose range from 10 mg twice a day to 450 mg twice a day through 13 dose levels. Part 1a also includes a parallel substudy (Substudy 1) consisting of at least 12 participants, aiming to test the effect of food and stomach acid on the levels of OKN4395 in the blood as well as its tolerability. Part 1b will evaluate OKN4395 alone and in combination with pembrolizumab administered on day 1 of each 21-day cycle in patients with selected cancer types. Part 1b will comprise 4 cohorts: Cohort 1 in sarcoma (OKN4395 alone), Cohort 2 in non-small cell lung cancer (NSCLC), Cohort 3 in colorectal cancer, and Cohort 4 in gastric cancer (GC), with cohorts 2 to 4 in combination with pembrolizumab. The overall study will enrol approximately 146 participants with up to 54 participants to receive OKN4395 alone and 12 participants to receive OKN4395 in combination with pembrolizumab in Part 1a, and 80 participants in Part 1b split: 20 on monotherapy and 60 on combination therapy. The study will be conducted in the US, Australia, UK and in the EU.

AI-Based Risk Prediction Model for Upper Digestive Tract Cancer

Upper digestive tract cancers are often preceded by pre-malignant lesions, but there is limited evidence regarding optimal risk prediction models and screening strategies for disease progression and cancer development. This prospective multicenter cohort study aims to establish a longitudinal database integrating clinical information, endoscopic findings, pathology, genetics, epigenetics, and gastrointestinal microbiota data from subjects undergoing upper digestive tract endoscopy. The study will develop explainable artificial intelligence (AI)-based risk prediction models to identify factors associated with disease progression, treatment response, and cancer development. Participants will be followed longitudinally to evaluate changes in lesion severity and clinical outcomes.

Development and Validation of the Surgical Assessment and Healthcare (SAH) Index for Gastric Cancer Treatment Evaluation

This study develops the Surgical Assessment and Healthcare (SAH) Index, a new tool to fairly evaluate gastric cancer surgery outcomes. Gastric cancer is a serious disease that often requires major surgery, but it can be difficult to compare how well different hospitals or surgeons perform because patients have different levels of risk before surgery. The SAH Index will help solve this problem by creating a standardized way to account for patient risk factors when evaluating surgical results. The study analyzes data from 780 patients who had gastric cancer surgery in 2019, looking at factors like patient age, tumor characteristics, molecular markers, and surgical outcomes. By combining clinical information (like patient health), pathological details (like tumor type), and molecular features (like genetic markers), the SAH Index will create risk categories that allow fair comparison of surgical outcomes. This tool could help hospitals improve their care, help patients and families understand their treatment options, and help doctors make better treatment decisions. The study uses only existing medical records and does not involve any new treatments or procedures. The goal is to create a practical tool that can be used by hospitals and doctors to better evaluate and improve gastric cancer surgery outcomes.

Multimodal AI for Predicting Response to Neoadjuvant Immunotherapy in Gastric Cancer (PRISM-GC)

Gastric cancer is a major global health challenge. Currently, a combination of chemotherapy and immunotherapy (PD-1 inhibitors) is frequently used before surgery to shrink tumors, a strategy known as neoadjuvant therapy. While this approach is effective for many patients, responses vary significantly, and there are currently no reliable tools to predict which patients will benefit the most before treatment begins. The PRISM-GC study aims to develop and validate a novel Artificial Intelligence (AI) system to address this need. This is a prospective, observational study that will collect data from patients diagnosed with locally advanced gastric cancer who are scheduled to receive standard neoadjuvant chemotherapy combined with immunotherapy in a real-world clinical setting. The specific choice of immunotherapy drug is determined by the treating physician and is not dictated by the study. Researchers will analyze standard preoperative CT scans and pathological tissue slides using advanced deep learning algorithms. The goal is to create a "multimodal" AI model that can accurately predict how well a tumor will respond to treatment (specifically, whether the tumor will disappear or shrink significantly). If successful, this AI tool could help doctors personalize treatment plans in the future, ensuring that each patient receives the most effective therapy while avoiding unnecessary side effects.

Prediction of Peritoneal Dissemination of Digestive Tumors Through the Study of Circulating Tumor DNA

The peritoneum is a relatively frequent metastatic site in digestive tumors (colon, stomach, pancreas) and is characterized by a poorer prognosis compared with other metastatic sites such as the lung or liver. Its dissemination pathway is complex and most often involves crossing the hemato-peritoneal barrier. This type of metastasis is difficult to visualize on imaging at an early stage, and surgical exploration may be required. In gastric cancer in particular, exploratory laparoscopy is part of the initial staging work-up for locally advanced tumors to assess the presence or absence of peritoneal metastases. It is therefore important to develop new, less invasive detection or prediction methods. Circulating tumor DNA (ctDNA) is a promising non-invasive blood biomarker that can assist clinicians as a prognostic/predictive biomarker and/or a tool for monitoring response to anti-tumor therapies. This marker is most often assessed in plasma, but recent data suggest that tumor DNA may also be detected in other biological fluids such as peritoneal fluid. A preliminary study conducted by our team showed the ability to detect tumor DNA in peritoneal fluid from patients with peritoneal carcinomatosis of various origins, with a sensitivity of 75%. In gastric cancer, a recent meta-analysis demonstrated an increased risk of peritoneal metastases when peritoneal tumor DNA was positive (RR 13.81 \[95% CI, 8.11-23.53\]), as well as a reduction in 3-year recurrence-free survival (RR 5.37 \[95% CI, 1.39-20.74\]) and overall survival (HR 4.13 \[95% CI, 1.51-11.32\]). The objective of this cohort is to evaluate the prognostic impact of circulating tumor DNA (ctDNA) in plasma and/or peritoneal fluid on the risk of developing peritoneal metastases. The primary endpoint is: Peritoneal recurrence rate according to tumor DNA positivity status (positive vs negative).

Immediate and Functional Results of Different Types of Reconstructions After Proximal Gastrectomy For Gastric and Esophagogastric Junction Cancer

Proximal gastric and esophagogastric junction cancers comprise up to 40% of gastric malignancies. For localized disease, proximal gastrectomy is the main radical procedure, but reconstruction of GI tract often leads to significant functional issues. Rising use of proximal resections and broader indications have increased attention to postoperative quality of life (QoL). Common reconstructions include direct esophagogastrostomy (various types), double-tract reconstruction, jejunal interposition, and newer anti-reflux anastomoses (e.g., double-flap, overlap, tunnel techniques). Each method has unique pros and cons regarding reflux esophagitis, food passage, dumping syndrome, nutritional changes, and long-term QoL. No consensus exists on the optimal technique, leading to variable practices and outcomes. Most research focuses on oncologic radicality and survival, while functional results and QoL remain understudied. Systematic evaluation of functional outcomes across reconstruction types after proximal subtotal gastrectomy is needed in Russian Federation to improve QoL, advance research, and standardize treatment of proximal gastric and EGJ cancers.

Efficacy of Sintilimab Combined With Bevacizumab and XELOX/SOX in Initially Unresectable AFP-positive Gastric/Gastroesophageal Junction Adenocarcinoma

Alpha-fetoprotein-producing gastric cancer (AFP-positive gastric cancer, AFP-GC), a rare and highly aggressive subtype of gastric cancer, accounts for 1.3% to 15% of all gastric cancer cases. Its clinical features are significantly different from those of common gastric cancer. Not only does it show abnormally elevated serum AFP levels, but it also has a stronger angiogenic ability, a higher rate of distant metastasis, and a poorer prognosis even after a upfront R0 surgery, making it a challenging problem in the field of gastric cancer treatment. Notably, patients with AFP-positive gastric cancer have a relatively low sensitivity to the traditional standard regimens. There is an urgent need to explore targeted treatment strategies to break through the efficacy bottleneck. Combination of sintilimab, bevacizumab and XELOX/SOX for initially unresectable AFP-positive gastric/esophagogastric junction adenocarcinoma could be a novel therapeutic strategy to increase response rate and therapeutic efficacy. This study is a multi-center, single-arm phase 2 clinical trial to evaluate efficacy, tolerability and safety of perioperative sintilimab in combination with bevacizumab and XELOX/SOX in initially unresectable AFP-positive gastric/esophagogastric junction adenocarcinoma.

Influence of Age on the Choice of Treatment and Prognosis in Patients With Resectable Gastric Cancer

Next-generation sequencing (NGS) and biomarkers play a key role in the diagnosis and personalized therapy of gastric cancer. These technologies provide a deep understanding of the molecular basis of the disease. NGS allows simultaneous analysis of multiple genes, identifying mutations and changes in their expression. In case of stomach cancer, this makes it possible to identify specific mutations to determine prognosis and treatment choice, study the genomic profiles of patients to find targets for targeted and immunotherapy. The use of NGS and biomarkers allows the development of individualized treatment regimens, increasing effectiveness and reducing side effects. Biomarker analysis also helps to track the progression of the disease and identify patients at high risk of relapse. The study of molecular genetic markers in tumor tissues, as well as the influence of genetic and age-related factors, is an important scientific and clinical task. Solving this problem will create a personalized approach to patient management. This work examines the influence of age on the choice of treatment tactics and prognosis in patients with resectable gastric cancer. The main focus is on the analysis of surgical, chemotherapeutic, topographic, pathomorphological, and molecular genetic correlations in various age groups.
