Filter by:Patients diagnosed with locally advanced esophageal squamous cell carcinoma (ESCC) that is deemed unresectable face a bleak prognosis. Recent phase 1/2 studies have demonstrated the efficacy and safety of augmenting neoadjuvant concurrent chemoradiotherapy with immunotherapy in treating resectable ESCC. The present study is a prospective, 3-arm, randomized trial that seeks to evaluate the efficacy of diverse conversion therapy modalities in patients with unresectable ESCC. The study objectives include R0 resection rate, treatment-related adverse events, morbidity and mortality, 1-year progression-free survival (PFS), and 1-year overall survival (OS) rates. Tislelizumab is a humanized IgG4 monoclonal antibody with high affinity/specificity for programmed cell death protein 1 (PD-1). Tislelizumab was specifically engineered to minimize binding to FcɤR on macrophages, thereby abrogating antibody-dependent phagocytosis, a potential mechanism of T-cell clearance and resistance to anti-PD-1 therapy. This trial will provide valuable insights into the effectiveness of the three conversion therapy modalities and help to inform clinical decision-making for patients with unresectable locally advanced ESCC.
This multicenter, prospective observational cohort study has the potential to optimize individualized chemoradiotherapy regimen for early-stage esophageal cancer patients who have received endoscopic submucosal dissection.
This study aims to develop a highly sensitive, specific, and cost-effective blood assay for the early detection of esophageal adenocarcinoma and its precursor lesions, using advanced machine learning and state-of-the-art biological analyses.
This study constitutes a case-control investigation employing a retrospective approach. Plasma samples from individuals with esophageal cancer, benign esophageal diseases, gastric cancer, benign gastric diseases, and a healthy control group were systematically collected. Advanced Data-Independent Acquisition (DIA) proteomics and single-vesicle membrane protein detection techniques were employed to quantify protein content within exosomes. Specific protein biomarkers indicative of early-stage upper gastrointestinal tumors were identified. External validation of these protein markers was conducted using Parallel Reaction Monitoring (PRM) technology on an independent validation cohort. The objective is to establish protein marker predictions for early diagnosis of upper gastrointestinal tumors and prognostication of therapeutic efficacy.
This trial on biomarker validation investigates the use of innovative re-staging FDG-PET parameters to detect highly chemoradiation (CRT) sensitive squamous cell carcinomas of the esophagus (SCEC) at the end of preoperative or definitive CRT.
The goal of observational study is to learn about the outcomes of the participants. The main questions it aims to answer are: 1. ESD additional postoperative radiotherapy in patients with non healing SESCC overall survival (OS) and disease-free survival (DFS) 2. The adverse events (AE) of additional radiotherapy after ESD for non-curative SESCC patients were counted, and its safety was evaluated. Participants will receive radiation therapy as necessary.
To analyze and compare the long-term recurrence-free survival rate, overall survival rate and quality of survival after minimally invasive esophagectomy and open esophagectomy, and to conduct subgroup analysis according to the type of esophageal cancer and pathological stage, etc., and to explore more deeply the differences between minimally invasive esophagectomy and open esophagectomy in terms of the benefits for different types of patients, so as to provide reference for the selection of the clinical surgical methods. We will also use the available data to analyze the influence of other factors on patients' long-term survival after surgery.
Definitive chemoradiotherapy (CRT) is the standard treatment option for unresectable locally advanced esophageal cancer. However, as high as more than 40% of patients with esophageal cancer experienced locoregional recurrence after definitive CRT. Immune checkpoint inhibitors targeting PD-1/PD-L1 and/or CTLA-4 have shown substantial clinical benefits in advanced esophageal cancer. Recently, the combination of immunotherapy with CRT has emerged as a promising strategy to improve clinical outcomes in esophageal cancer. The aim of this study was to evaluate the efficacy and safety of cadonilimab (a bispecific PD-1/CTLA-4 antibody) combined with induction chemotherapy followed by definitive radiotherapy in patients with locally advanced esophageal squamous cell carcinoma.
This study is a open-label, dose-escalating + dose-expansion clinical study, aiming to evaluate the safety and efficacy of CEA-targeted CART cell preparations, and to reliminarily observe the study drug in CEA-positive advanced malignant tumors. The pharmacokinetic characteristics of CART cell preparations for the treatment of patients with CEA-positive advanced malignancies were obtained and the recommended dose and infusion schedule.
A prospective, multi-centre, exploratory and observational one-arm study to evaluate preventive Endoluminal Vacuum Therapy(pEVT) to prevent anastomotic leakage after esophagectomy due to esophageal cancer. The main objective is to evaluate the potential protective effect of prophylactic preemptive endoluminal vacuum therapy on esophageal-gastric anastomosis dehiscence after esophagectomy.
