Active clinical trials for "Esophageal Neoplasms"

The aim of this study is to demonstrate the influence of peri-operative nutrition on the post-operative complications, preservation of lean body mass and length of stay after gastrectomy or oesophagectomy.

The purpose of this study is to test 2 different methods of surgery to remove cancer in the esophagus. This research is being done to see whether removing more tissue and lymph nodes surrounding the tumor in the esophagus (known as transthoracic en bloc esophagectomy) offers better control of the cancer than removing less tissue and lymph nodes (known as non-en bloc esophagectomy).

Prospective, single-center, nonrandomized, explorative imaging study evaluating the value of PET as a predictor of histopathological response in metabolic non-responders Patients with resectable AEG (adenocarcinoma of the esophagogastric junction) type I and II (cT3/4 and/or cN+ and cM0) Metabolic non-responders, showing a <35% decrease of SUV (standardized uptake value) two weeks after the start of neoadjuvant chemotherapy are eligible for the study and are taken to intensified taxane-based RCT (radiochemotherapy) before surgery. 18FDG-PET scans will be performed before (=Baseline) and after 14 days of standard neoadjuvant therapy as well after the first cycle of Taxotere/Cisplatin chemotherapy (=PET1) and at the end of intensified radiochemotherapy (PET2). Tracer uptake will be assessed semiquantitatively using standardized uptake values (SUV). The percentage difference Delta SUV=100(SUVBaseline-SUVPET1)/ SUVBaseline will be calculated and assessed as an early predictor of histopathological response. In a secondary analysis, the association between the difference SUVPET1 - SUVPET2 and histopathological response will be evaluated.

The purpose of the study was to test a null hypothesis that a combined modality treatment of esophageal cancer with neoadjuvant chemotherapy or chemoradiotherapy is equivalent to surgery alone and what are the benefits from adding irradiation to chemotherapy in neoadjuvant treatment of esophageal cancer.

The purpose of this study is to improve their outcome by either changing the chemotherapy drugs or giving them radiation therapy with concurrent chemotherapy, hoping that this will improve their outcome.

This study is a multicenter cross-sectional survey of esophageal cancer patients who underwent radical chemoradiotherapy/radiotherapy from July 2017 to July 2020 in various medical centers, and who survived without disease progression at the time of the survey. The purpose of this study is to evaluate the current quality of life, as well as the incidence of long-term toxic side effects, nutritional status, and psychological status of esophageal cancer patients cured by radiotherapy.

This is a phase II, open-label, single arm, single-stage study. A total of 23 evaluable patients will be enrolled. If total number of patients free of disease relapse at 1 year is less than or equal to 15, the drug would not be considered for further study in this setting. After six patients are treated with at least one dose of study drug, they will be observed for a minimum of 60 days. During the 60-day observation period, further accrual will be halted to evaluate "unacceptable toxicities warranting early closure of the trial" defined as: Any definitive durvalumab-related death. A durvalumab-related death will be continuously monitored throughout the trial and the trial will be suspended for re-evaluation whenever such an event is confirmed. Any unexpected and previously unreported grade 4 toxicities definitely related to durvalumab.

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.

This is a unicentered phase I/II study to explore the dose of paclitaxel and cisplatin with radiation therapy, and to document the adverse events for further clinical trial.

The main purpose of this study is to evaluate the efficacy of an alternative dose of ramucirumab in combination with paclitaxel in participants with second-line metastatic or locally advanced, unresectable gastric or gastroesophageal junction adenocarcinoma (GEJ).
