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.
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.

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.
NCT05624099

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).

NCT03474341
Rationale: For locally advanced esophageal cancer the standard treatment consists of 5 weeks of neoadjuvant chemoradiotherapy (nCRT) followed by surgery. Surgery is currently performed independent of the response to nCRT and is associated with substantial morbidity. Prior knowledge of the eventual response to nCRT would greatly impact on the optimal care for many esophageal cancer patients for two imperative reasons: Firstly, it is argued that patients who achieved a pathologic complete response (pCR, 29%) may not have benefitted from surgery. Consequently, proper identification of pathological complete responders prior to surgery could yield an organ-preserving regimen avoiding unnecessary toxicity. Secondly, non-responders are exposed to the side effects of nCRT without showing any tumor regression. Early identification of the non-responders during nCRT would be beneficial for this group as ineffective therapy could be stopped, and for who altered treatment strategies could be explored. Objective: To develop a multimodal model that predicts the probability of pathologic complete response to nCRT in esophageal cancer, by integrating diffusion weighted magnetic resonance imaging (DW-MRI) and dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) in conjunction with combined 18F-fluorodeoxyglucose positron emission tomography and computed tomography (18F-FDG PET-CT) scans acquired prior to, during and after administration of nCRT. Study design: Multi-center observational study Study population: Patients (\>18 years) with potentially resectable locally advanced squamous cell- or adenocarcinoma of the esophagus or gastroesophageal junction, receiving nCRT prior to surgery. Intervention: In addition to the standard diagnostic work-up for esophageal cancer that includes a 18F-FDG PET-CT scan at diagnosis and after nCRT, one 18F-FDG PET-CT scans will be performed during nCRT, as well as three MRI scans (before, during and after nCRT) within fixed time intervals. Furthermore, after response imaging after nCRT has been performed, but prior to surgery, patients will undergo (on an opt-out basis) an endoscopy and/or endoscopic ultrasonography (EUS) with biopsies of the primary tumor site, other suspected lesions and suspected lymph nodes. Furthermore, blood samples will be collected at three time points. Main study parameters/endpoints: An accurate multimodal prediction model for the patients' individual probability of pathologic complete response after nCRT, based on the quantitative parameters derived from a longitudinal series of DW-MRI, DCE-MRI and 18F-FDG PET-CT datasets.

NCT02911363
The main purpose of this study will be to two-fold; firstly to determine whether the use of a Captivator tissue cassette has an effect on the preservation of tissue histology (minimizing artifactual curling) , and secondly to determine whether the use of a intraprocedural cassette is practical. The investigators believe that this will greatly aid in elucidating the best technique for optimizing performance of EMR for esophageal lesions.
NCT03223662
Background: The number of patients with esophageal cancer keeps rising. For many patients, a combination of surgery, chemotherapy, and radiation is necessary to completely treat the disease. Usually, patients receive chemotherapy and radiation at the same time followed by surgery to remove the part of the esophagus with the tumor (Neoadjuvant chemoradiotherapy (nCRT)). Researchers want to learn how to make this treatment more effective. Objective: To see if biopsies before treatment can show which patients will do the best with a combination of chemotherapy, radiation, and surgery. Eligibility: Adults at least 18 years old with esophageal adenocarcinoma or squamous cell carcinoma who should be treated with chemotherapy, radiation, and surgery. Design: Patients will undergo standard testing that is routine for all patients with this disease. These tests include: Medical history Physical exam with activity and nutritional assessment Standard lab tests Imaging studies including a computerized axial tomography (CAT) scan and positron-emission tomography (PET) scan Breathing test into a machine to measure size and function of lungs. Biopsy for a small sample of tumor is removed by esophagogastroduodenoscopy (EGD): A tube inserted into the mouth under anesthesia Endoscopic ultrasound is performed in some but not all patients. Patients will have nCRT at the clinic or with their local doctor. In 6 -12 weeks after nCRT, patients will undergo surgery with: 1. A robotically-assisted, minimally-invasive esophagectomy 2. Or, a traditional, open approach. After surgery, patients are usually in the hospital for 2 weeks and have a feeding tube for at least 2 weeks and potentially longer until they are eating enough to not lose weight. Patients will return for follow-up visits with labs and CAT scans every 6 months for the first two years then every year afterwards.
NCT03254511
This is a randomized, single blind, multi-center, phase two clinical trial. Inclusion criteria are consist of non-metastatic esophageal cancer who are going to receive chemo-radiotherapy. Sample size is 100 people (50 people in each group). In the intervention group, patients are going to inject an enoxaparin (40 mg) daily concurrent by chemo-radiation. Therefore patients with esophageal cancer are going to assign randomly to control group (only chemo-radiotherapy) and intervention group (chemo-radiotherapy+enoxaparin) using 1:1 allocation. Four to 6 weeks after treatment, all patients undergo upper GI endoscopy and then esophagectomy. Endoscopic and pathological findings (after esophagectomy) are considered as clinical and pathological response, respectively.
