Active clinical trials for "Esophageal Neoplasms"

The purpose of this study is to find out more about differences of the quality of life in patients undergoing total gastrectomy or proximal gastrectomy for adenocarcinoma of esophagogastric junction. To find a better reconstruction for patients who received total gastrectomy.

The purpose of this study is to show if the adoptive cellular therapy with autologous dendritic cells and cytokine-induced killer cells (CIK) combined with concurrent chemoradiation could improve the quality of life of the patients with locally advanced esophageal cancer, compared with concurrent chemoradiation only.

This prospective study was designed to assess the outcomes (survival and failure patterns) of therapy for localized esophageal cancer with conventional dose radiation (RT; 50.4 Gy) with concurrent continuous infusion 5-fluorouracil (5-FU) and weekly carboplatin/paclitaxel. Patients with less than complete response (CR) or partial response (PR) received dose escalation of radiation to 59.4 Gy with the same chemotherapy.

The fluorescent laparoscopic technique would be applied to the radical resection of gastric cancer at the junction of esophagus and stomach, and compared with the traditional laparoscopic radical resection of gastric cancer to find a better surgical method for patients

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.

The purpose of this multi-center prospective cohort study is to study the health-related quality of life (HRQL) together with other outcomes of patients with esophageal cancer after surgery in China.

The main question of this study is if and when VEGF (vascular endothelial growth factor) expression in the tumor is upregulated during chemoradiation and if bevacizumab inhibits subsequent vessel growth in the tumor. Therefore the first aim of this study is to identify the time point of induction of VEGF in the tumor tissue of esophagus carcinoma during chemoradiation (after 1,2,3 or 4 weeks of chemoradiation). If we identify increased expression of VEGF at a certain time point, our second aim is to determine if we can inhibit the subsequent tumor vessel growth by administration of bevacizumab.

Radiation therapy plus concurrent chemotherapy is now the standard therapy for patients with localized carcinoma of the esophagus selected for nonsurgical treatment. The standard radiation dose is 50-50.4Gy/1.8-2.0Gy/F.All of this were based on 2D radiation technology. Entering new century, 3D-CRT or IMRT has used on esophageal cancer. In China,the recommend radiation dose of concurrent chemoradiation was 60Gy. The study is a clinical phase III, randomized trial to compare the different radiation dose(60Gy vs 50Gy) of concurrent chemoradiation using 3D-CRT or IMRT in patients with unresectable esophageal carcinoma.

The purpose of this study is to evaluate overall survival and immunological monitoring for peptide vaccination therapy using novel cancer testis antigens (STF-II) for locally advanced, recurrent, or metastatic esophageal squamous cell carcinoma

This is an open label, non-randomised, multicentre phase 1-2 study with a fixed dose of Taxotere in combination with Xeloda which is dose escalated during the first phase of the study (modified Fibonacci design) and fixed during the second phase. The primary objective of the phase 1 part is to define the dose recommended for the Phase II part of the study. The primary objective is to determine the response rate.
