Filter by:The purpose of this study was to demonstrate superiority of treatment with avelumab plus best supportive care (BSC) versus physician's choice (chosen from a pre-specified list of therapeutic options) plus BSC.
This study aims to first apply near-infrared fluorescence imaging technology in thoracic surgery with indocyanine green in China. To evaluate the feasibility usage of the investigators' fluorescence imaging systems and the safety applications in intraoperative sentinel lymph node mapping of lung and esophageal cancer, lung nodule imaging, lung segment resection boundary determination, esophagus - tubular anastomosis, thoracic duct imaging and chylothorax repairing thoracic surgery. Aim to achieve precise boundaries definition during thoracic surgery and realize accurate, minimally invasive thoracic surgery with fluorescence imaging technology.
To investigate the feasibility of evaluation of prevalence and clinical significance and relevance of circulating tumor cells (CTC) in the blood of patients with resectable adenocarcinoma of the esophagus (EAC) treated with multimodal therapy in a pilot study. The primary hypothesis is that the number of CTC correlates with tumor burden and response to treatment. One established and one experimental CTC detection platform will be investigated. Investigators will evaluate the prevalence and enumeration of CTC before neoadjuvant treatment (time point 1), after neoadjuvant treatment & before operation (time point 2) and after the operation (time point 3). Results will be compared with healthy controls (one time point) and correlated with conventional response to treatment evaluation. The persistent presence of CTC could be a marker for worse response to treatment and predict early recurrence.
This study aimed at assessing the efficiency and safety of concurrent chemoradiotherapy (CCRT) using paclitaxel (PTX) plus oxaliplatin (OHP) in unresectable locally advanced esophageal cancer patients.
Nimotuzumab (hR3) is an IgG1 humanized monoclonal antibody that recognized an epitope located in the extra cellular domain of the human epidermal growth factor receptor (EGFR). Clinical efficacy has been shown in adult with head and neck cancer. The phase II study assessed the efficacy and safety of the combination of Nimotuzumab administered concomitantly with radiotherapy in patients with esophageal cancer tumours.
This is a single-arm, single-center, open-label trial of pembrolizumab (MK-3475) in subjects with advanced gastric or gastroesophageal junction (GEJ) adenocarcinoma who have progressed after failure of any combination chemotherapy containing a platinum and a fluoropyrimidine agent. Approximately 60 subjects will be enrollment to evaluate the efficacy and safety of pembrolizumab. Enrollment will begin with all subjects without regard for PD-L1 expression status. An evaluable specimen for PD-L1 status must be available and confirmed prior to enrollment. All study subjects will be evaluated every 6 weeks (+/- 7 days) following the date of IP drug adminstration for the first six months and every 12 weeks (+/- 7 days) thereafter until progression of disease is documented with radiologic imaging (computed tomography or magnetic resonance imaging). In the expansion cohort (cohort B), it was expanded on the original cohort based on response analysis and will be opened separately. Of the 5 MSI-high patients who were enrolled on to original cohort, all 5 MSI high GC patients (100% response rate) demonstrated dramatic response rate. Based on this finding, in order to proven Pembrolizumab's efficacy to specific MSI-H GC population, we would like enroll 20 more patients in cohort B. Based on our screening protocol, the prevalence of MSI-high in GC is about 15 %. Only MSI-high GC patients will be included. All the eligibility will be the same.
The purpose of study is to evaluate the efficacy and safety of Nivolumab in unresectable advanced or recurrent esophageal cancer patients who have failed in standard chemotherapies.
In this study, participants with advanced or metastatic adenocarcinoma or squamous cell carcinoma of the esophagus or Siewert type I adenocarcinoma of the esophagogastric junction (EGJ) that had progressed after first-line standard therapy were randomized to receive either pembrolizumab (MK-3475) OR the Investigator's choice of standard chemotherapy with paclitaxel, docetaxel, or irinotecan. The primary study hypothesis was that treatment with pembrolizumab would prolong overall survival (OS) as compared to treatment with standard chemotherapy.
In this study participants with advanced/metastatic adenocarcinoma of the esophagus (EAC), squamous cell carcinoma of the esophagus (ESCC), or advanced/metastatic Siewert type I adenocarcinoma of the esophagogastric junction (EGJ), who had been previously treated with two standard therapies, will be treated with pembrolizumab.
First intent treatment for superficial circular esophageal neoplasm is surgical resection. Endoscopic mucosal resection is not recommended due to the high rate of subsequent esophageal stenosis (higher than 80%). Surgical limits are related to a high level of morbidity due, in particular, to respiratory complications or infections that require prolonged hospitalisations, and by significant rate of mortality (from 2 to 5 %). As an alternative to the surgical treatment, an innovative technique to remove esophageal circular preneoplastic and neoplastic lesions has been developed: it consists to ablate the mucosa by means of a balloon of a fixed diameter which incorporates approximately 100 electrodes on its surface that emit radiofrequency waves (HALO® Radiofrequency Ablation Technology System). By varying the strength and the duration of the electrical impulses, it is possible to obtain a homogenous and controlled destruction of the tissue of the whole mucosa, leaving no remaining pre-neoplastic or neoplastic elements underneath. The technique will be used for high grade glandular epithelial neoplasia, Vienna 4-1 or 4-2, developed on a mucosa at risk, i.e. the Barrett's oesophagus, occupying more than half of the circumference of the esophagus and that requires surgical treatment. The expected benefit for the patient is linked to the reduced invasiveness of the technique in comparison to the surgery
