Active clinical trials for "Esophageal Neoplasms"

The aim of our study was to demonstrate the efficacy and feasibility of the medical consortium for screening upper gastrointestinal cancers with magnetically controlled capsule gastroscopy.

The role of preoperative chemotherapy as standard therapy is well-established for advanced esophageal cancer. Immunotherapeutic agents such as Immune checkpoint inhibitors has been shown to improve objective response rate in solid tumors. However, there is a paucity of data regarding the efficacy and safety of preoperative immunotherapy plus chemotherapy in esophageal cancer patients in real-world practice. This study set out to investigate whether the combination of preoperative chemotherapy and immune checkpoint inhibitors is beneficial to improve the objective response rate as well as the pathological complete response rate in a real-world scenario.

The aim of this study is to investigate urokinase Plasminogen Activator Receptor (uPAR) microexpression in gastroesophageal cancer (adenocarcinomas) both qualitatively and semi-quantitatively and to evaluate if it offers a possibility for future imagining purposes.

By using a novel technique of extraesophageal saline injection (ESI),the esophagus is to be separate from the adjacent organs.The space between esophagus and adjacent organs can be detected by endoscopic ultrasonography enhanced with ESI.Therefore, ESI plus with EUS is to be differentiate between T3 and T4 stage esophageal squamous cell carcinoma (ESCC). The objective of this Phase Ⅰstudy is to confirm the safety and efficacy of ESI.

To create an esophageal cancer biospecimen repository that will collect, annotate, store and distribute human esophageal cancer biospecimens in a manner that embraces the highest ethical standards of human subject's research, that conforms to the best practices of biorepository science and that furthers basic, translational and clinical research in the understanding diagnosis and treatment of this disease.

To collect efficacy and outcomes data related to the use of trūFreeze® spray cryotherapy for the treatment of unwanted tissue in the pulmonary and gastrointestinal settings.

Primary Objectives: To determine the feasibility of a study that would describe changes of certain circulating inflammatory cytokines (interleukin-1, 6, 8, 10, 12, and tumor necrosis factor-alpha [TNF] and symptoms related to chemoradiation therapy (pre-therapy, during therapy and up to 3 months post-therapy) among patients with lung, esophageal, gastric, colorectal and anal cancer. To determine the feasibility of studying neurocognitive function in patients with non-small cell lung cancer (NSCLC) at presentation and during chemoradiation therapy to determine the prevalence, severity, and pattern of cognitive symptoms.

The purpose of this study is to create a patient registry to collect and analyze post-510K approval information on subjects treated endoscopically with the CryoSpray Ablation™ System.

Study Hypothesis: PANCHO is a prospective randomized, predictive marker study, evaluating the interaction between the potential predictive marker 'p53 genotype' and response to induction chemotherapy in patients with esophageal cancer considered resectable. 170 patients with measurable disease will be enrolled in this study. After testing the marker genotype (two genotypes: p53 normal or p53 mutant) patients will be stratified according to histological subtype only (adeno- or squamous cell carcinoma) and will be randomly assigned to receive 3 cycles of either 5-fluorouracil (5FU)/cisplatin or docetaxel monotherapy as neoadjuvant therapy. All patients will be rendered to subsequent surgery in order to assess both clinical and pathohistological response.

The overall goal of this project is to determine whether polycyclic aromatic hydrocarbons (PAHs) are contributing to the high rate of esophageal cancer in Linxian, China. Esophageal cancer is one of the most fatal cancers worldwide with Linxian, China having one of the highest rates in the world. In the United States esophageal cancer causes approximately 10,000 deaths each year. It is the fourth most common cause of cancer death in black males and the eighth leading cause of cancer death in men of all races. Although several recent studies have identified some of the molecular changes associated with esophageal cancer, its prevention and treatment within high risk groups continues to be limited by our inability to identify specific etiologic agents. Human exposure to PAHs, including benzo [a]pyrene (B[a]P), is associated with an increased rate of skin, lung, and upper GI tumors and also with an increased mortality from causes related to atherosclerosis. Evidence, including the preliminary results from histologic and food analysis pilot studies, supports the idea that this region's high rate of esophageal cancer may be related to long-term, high-level exposure to PAHs via inhalation of air-borne pollution and ingestion of food cooked with soft coal. Thus, to assess the association of PAHs with the high rate of esophageal cancer in Linxian, China, we plan to analyze samples of food for the presence of PAHs, samples of blood for Hb adducts (a marker of long-term PAH exposure), samples of urine for 1-OH-Pyrene glucuronide (a maker of short-term PAH exposure), and samples of coal for characteristics that may be associated with increased carcinogenesis. We will also administer environmental questionnaires that will include questions about the type of fuel used for cooking and heating, the location and type of stove and/or heating unit (i.e., vented versus unvented), and time spent cooking.
