NCT06380816
This clinical trial is looking at UCB4594. This is the first time the drug is being tested in humans. UCB4594 is a type of drug called a monoclonal antibody. It has been designed to work by targeting a protein called human leucocyte antigen G (HLA-G) that is found in high levels on some cancer cells. By attaching itself to this protein it may help the immune system to attack and kill the cancer cells. The four main aims of the clinical trial are to find out: 1. The best dose of UCB4594 that can be given safely to participants in the trial. 2. What the side effects of UCB4594 are and how they can be managed. 3. What happens to UCB4594 inside the body and how it affects cancer cells. 4. Whether UCB4594 can cause cancer to shrink.
NCT00213486
The standard non surgical therapy of locally advanced esophageal cancer is based on a definitive concurrent chemoradiotherapy regimen with fluorouracil and cisplatin. One of the alternative regimen which is being studied is the combination of a weekly cisplatin and irinotecan schedule with radiotherapy. This multicentric phase II clinical trial primarily aimed to evaluate the clinical complete response rate and secondary objectives were toxicity profile and survival.
NCT05875870
This study plans to investigate the effectiveness of six-week light exposure combined with an exercise training program on improving sleep-wake rhythm, physical and mental symptoms, quality of life, one-year recurrence rate, and one-year survival rate of patients with lung and esophageal cancer.
NCT06027515
The goal of this research study is to investigate the feasibility of implementing a prehabilitation program that aims to improve a patient's physical, nutritional, and sleep health before surgery in an older, at-risk group with esophageal cancer.
NCT03153280
This study is a phase Ib, open label, multi-centre trial designed to estimate the Maximum Tolerated Dose (MTD) of lithium when combined with a standard chemotherapy regimen of oxaliplatin and capecitabine in patients with advanced, unresectable, oesophago-gastric or colorectal cancer who have received no previous treatment for advanced disease (previous adjuvant or neo-adjuvant treatment is acceptable if completed at least 6 months prior to registration). The study follows a modified Fibonacci, 3+3, dose escalation design. Patients are enrolled in cohorts of 3. All three patients in each cohort must complete at least two cycles of treatment to be evaluable for toxicity. If a patient cannot complete 2 cycles, another patient will be enrolled.
NCT07035587
This is a combined prospective and retrospective observational study aiming to validate a highly sensitive and specific blood-based method for the early diagnosis and post-treatment monitoring of multiple cancers. The study leverages a newly developed sequencing method to improve the detection of circulating tumor DNA (ctDNA) in blood, focusing on enhancing sensitivity and specificity in clinical applications. The study targets patients with ovarian, lung, pancreatic, colorectal, esophageal, breast, kidney, bladder, and gastric cancer, as well as healthy controls with asymptomatic gallstones, benign polyps, or individuals undergoing routine medical screening. Blood samples will be analyzed for cell-free DNA (cfDNA), RNA, and protein profiles. A key objective is to determine how much the newly developed method increases the sensitivity and specificity of ctDNA detection, especially in early-stage cancers and minimal residual disease (MRD) after treatment. The method evaluates the variant allele frequency (VAF) of ctDNA to detect residual disease and track tumor dynamics. Serial blood sampling will be conducted before and after surgery or chemotherapy and during follow-up outpatient visits in cancer patients, while one-time sampling will be done for controls. Additionally, tissue biopsies collected during surgery will be used to analyze concordance between tumor-specific mutations and those found in ctDNA. Primary outcome measures include quantitative differences in ctDNA or RNA levels between cancer and control groups. Secondary outcomes assess the clinical correlation between changes in ctDNA VAF and patient outcomes such as recurrence and survival. Statistical tools including ROC curve analysis, Cox regression, and log-rank tests will be used to quantify performance. This study seeks to establish a clinically robust, non-invasive diagnostic tool that enables earlier detection and more precise treatment decisions, while potentially reducing physical, psychological, and socioeconomic burdens related to cancer care.
NCT06077981
This is a randomized, single-center clinical trial that will compare the efficacy of two substances used in the submucosal cushion formation stage of endoscopic submucosal resections of early esophageal malignant neoplasms. Such substances are hyaluronic acid in the form of TS-905 Blue Eyeₒ and hydroxyethylamide (Voluven®).
NCT06070376
Esophageal cancer is the seventh most common type of cancer in the world, with an estimated global incidence of 604,100 new cases per year. The main symptom of esophageal cancer is dysphagia, associated or not with weight loss. Unfortunately, due to asymptomatic presentation in the early stages, more than half of patients are diagnosed in advanced stages of the disease, becoming ineligible for treatment with curative intent. In this sense, chemotherapy and radiotherapy are the pillars of palliative treatment, often regressing the injury and improving symptoms. However, some patients persist with dysphagia. In this scenario, esophageal prostheses are one of the main tools in the palliative treatment of esophageal cancer dysphagia, obtaining rapid and lasting relief of dysphagia. This study aims to compare fully covered (FC-SEMS) and partially covered (PC-SEMS) esophageal prostheses in this context, evaluating the number of reinterventions in each group, as well as the occurrence of adverse events. However, it is expected that with the data obtained it is possible to develop clearer and more effective protocols in the palliation of malignant dysphagia of esophageal stenosis.

ActivSight™ combines an innovative form factor and proprietary software to deliver precise, objective, real-time visualization of blood flow and tissue perfusion intraoperatively for laparoscope-based surgery. A small adaptor that fits between any existing laparoscope and camera systems and a separate light source placed along any current commercial system will deliver objective real-time tissue perfusion and blood flow information intraoperatively. Primary Objective: To determine the feasibility of ActivSight™ in detecting and displaying tissue perfusion and blood flow in the conduit and foregut anastomoses in esophageal resection/reconstructive surgery. The investigators will compare the precision and accuracy among the naked eye inspection, ICG and LSCI in assessing the vascularity of the conduit.
NCT05680077
The goal of this observational study is to test the clinical efficacy of "KCNA3 and OTOP2 gene methylation combined detection kit (fluorescence PCR method)"in esophageal cancer and high-grade esophageal neoplasia auxiliary diagnosis.The main questions it aims to answer are: 1. How consistent are the test results of the kit with the clinical reference diagnostic criteria? 2. Sanger sequencing can visually show whether each sample contains methylation sites, so in this clinical trial, the kit results were compared with Sanger sequencing results to analyze the reagent's accuracy in detecting KCNA3 and OTOP2 gene methylation. Each participant is required to provide no less than 10 ml of blood to complete the kit test.
NCT02381249
Improvements to treatment strategies for patients with cancers of the upper gastrointestinal tract have produced a large population of people who remain free from cancer recurrence in the long term following treatment. Surgery is the cornerstone of treatment for patients with these cancers, but while surgical removal of the tumour may offer the best chance of cure, these are major operations associated with specific long term complications. Weight loss and poor nutrition are common problems among patients who attain long-term cancer remission and cure after surgery. The mechanisms underlying these problems are not well understood and therefore treatment options are limited. Our research has demonstrated increased levels of chemical messengers (gut hormones) released from the gastrointestinal tract after meals in patients who have previously undergone this type of surgery. These chemical messengers play a role in controlling appetite and interest in food, and increased levels after surgery may reduce interest in eating. Understanding the role of gut hormones in the control of appetite may allow us to use certain medications to block gut hormones and hence increase appetite, allowing patients to eat more and regain weight, preventing nutritional problems after surgery. In this study, the investigators aim to determine whether exaggerated gut hormone secretion causes reduced appetite and interest in food after surgery. The information gained from this study may help us to develop treatments for patients with weight loss and nutritional problems after surgery.
NCT05624099
This is a prospective single-arm exploratory clinical study. The efficacy and safety of camrelizumab combined with chemoradiotherapy and camrelizumab combined with chemotherapy were evaluated in patients with advanced esophageal cancer who had not previously received any systemic antitumor therapy for esophageal cancer.
NCT05688020
Endoscopic resection of gastrointestinal lesions may prevent cancer. However, resection is associated with adverse events such as bleeding. Tranexamic acid (TXA) is a synthetic derivative of lysine that exerts antifibrinolytic effects and may prevent bleeding. The investigators aim to evaluate the effect of local TXA on preventing intraprocedural and postprocedural bleeding in patients undergoing endoscopic mucosal resection (EMR) of upper gastrointestinal lesions.
NCT01807936
This is a clinical trial from Eastern Cooperative Thoracic Oncology Project (ECTOP), numbered as ECTOP-2002. Esophageal carcinoma is an aggressive disease with a poor prognosis. Surgical resection with radical lymphadenectomy remains the basic method of management of this malignancy. Lymph node metastasis is one of the most important factors in predicting the prognosis of patients with esophageal carcinoma, but the extent of lymph node dissection is still in debate, and there is no statistical evidence based on large scale prospective randomized trials with regard to the issue that which is the optimal extent of lymphadenectomy for esophageal cancer. The purpose of this study is to test two different extents of lymphadenectomy (Cervical-thoracic-upper abdominal three-field lymphadenectomy and Thoracic-upper abdominal two -field lymphadenectomy) in middle or lower third intrathoracic esophageal cancer. This research is being done to see whether one extent of lymphadenectomy is superior than the other with better long-term outcome and acceptable postoperative short-term outcome or not.
NCT05619016
The goal of this phase II clinical trial is to improve the selection of patients with solid tumors who would benefit from effective treatment with HER2 targeted drugs. This will be achieved by examining patients with HER2 positive tumors in the esophagus or stomach or patients with advanced breast cancer with low HER2 expression (HER2low) with the HER2 specific positron emission tomography (PET) tracer ABY-025 (HER2-PET) and compare the imaging results with HER2 expression in tumor tissue derived from biopsies (reference standard).
