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 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.
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.
The objective is to investigate the safety and effectiveness of rhomboid intercostal and subserratum plane (RISS) block for postoperative analgesia after minimally invasive McKeown esophagectomy (MIE-McKeown).
This is a single-arm, open, dose-increasing phase I clinical study to explore the safety, tolerability and pharmacokinetic characteristics of the drug C-13-60 cells, and preliminarily observe the efficacy of the drug in CEA positive late malignant solid tumors, and explore the applicable dose regimen for phase II clinical trials.
The goal of this observational study is to screen and differentiate common cancers in participants with or without suspicious lesions. The main question the investigators aim to answer is: Can the developed model, using peripheral blood cell-free DNA sequencing, work well in screening and classifying common cancers especially in the early stages? Participants will undergo the collection of 15~20ml of blood and 1~2 telephone follow-up calls.
This is a phase I clinical study to evaluate the safety and tolerability of CAR-T in patients with CEA-positive advanced/metastatic solid tumors, and to obtain the maximum tolerated dose of CAR-T and phase II Recommended dose.
