Active clinical trials for "Esophageal Neoplasms"

This descriptive cross sectional study aims to directly compare the diagnostic capability of the probed-based confocal laser endomicroscopy (pCLE) and the magnifying narrow band imaging (M-NBI) in the Lugol's voiding lesions.

The purpose of this study is to determine whether narrowband imaging (NBI) makes it easier for a surgeon to see cancer. NBI is a kind of light. Normally, white light is used during surgery. White light uses many wavelengths of light. NBI only uses two wavelengths which highlight the blood vessels. This makes it easier for the surgeon to see blood vessels. Tumors often have more blood vessels than normal tissue. As a result, NBI may make it easier for the surgeon to see small tumors. In this study the surgeon will look with both normal white light and NBI. This way a comparison can be made to determine which is superior. Improved identification of tumors allows doctors and patients to make informed decisions about whether treatment is needed after surgery. It also provides additional information to determine which treatments may be best.

FDG PET-CT image acquisition in the abdominal and thoracic region is influenced by organ motion. Respiratory movement blurs the metabolic signal of the esophageal tumor and lymph nodes. The investigators hypothesize that the metabolic signal obtained with motion compensation results in higher SUV-max values and clearer demarcation of the esophageal tumor and lymph nodes.

The purpose of this study is to evaluate the investigators ability to obtain reliable and meaningful 11C-Choline PET-CT images of esophageal cancer.

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

We hypothesize that one-cycle induction chemotherapy may also help to identify chemo-responsive esophageal cancer patients who are highly treatable by definitive CCRT.

Nasogastric decompression is standard practice after esophageal resection in most centers because it is expected to reduce the incidence of esophagogastric anastomotic leakage by preventing overdistension of the gastric conduit. Most esophageal surgeons have been reluctant to move away from this tradition because of the considerable morbidity of anastomotic leaks after esophagectomy. However, a contrarian view is that the use of prolonged NGD may increase the incidence of postoperative pulmonary complications by promoting aspiration. Considering the numerous complications caused by using the tube and the uncertainty about its usefulness and the scarcity of studies conducted on the subject, particularly in patients with esophageal cancer, the necessity of using the tube in these types of cases is investigated in the present study.

The LOCARE-Trial is an investigator initiated, randomized-controlled trial with two parallel arms (n=60 each) and investigates the influence of esophageal washout on long-term outcomes in patients undergoing elective esophageal resection for carcinoma. The primary endpoint is defined as local carcinoma recurrence. Secondary endpoints will be locoregional and distant recurrence, disease-specific survival and esophageal cancer specific survival.

This study evaluates the role of narrow band imaging (NBI) endoscopy compared with Lugol chromoendoscopy in the early detection of esophageal cancer in patients with prior head and neck cancers.

Importance: There are no global screening recommendations for esophageal squamous cell carcinoma (ESCC). Endoscopic screening has been investigated in high incidence areas of China since 1970's. But up until now there no apparent evidence that would lead to a reduction in disease morbidity and mortality. Objective: To evaluate whether endoscopic screening and early intervention program could reduce the incidence or mortality of ESCC. Design: Community-based, controlled cohort study among 45 386 residents, Endoscopy screening was completed from November 1999 to May of 2000. Subjects in intervention group were examined once during intervention period. The study follow-up concluded in December 2009. Setting: High risk area of ESCC in China Participants:Cluster sampling from communities with high rates of esophageal cancer. A set of villages with was selected as the study intervention community. Age 40 to 69 years residents were selected as an eligible population. Another set of villages was select as the control population. Buffer villages were set up between intervention and control group. Intervention: Endoscopy with Lugol's iodine staining and early treatment on precancerous lesions was undergone for the intervention group. Main Outcome(s) and Measure(s): Incidence and mortality ESCC
