This is a feasibility study testing the use of the Cytosponge™ device in patients with known oesophageal cancer treated with pre-operative or definitive chemoradiation. All participants will receive one Cytosponge™ procedure at one time-point within 4-16 weeks after completion of chemoradiotherapy.
The hypotheses are: 1) the intestinal stem cell marker, DCLK1, which is increased in both the epithelium and stroma in colon cancer is also increased in BE (Barrett's esophagus) with HGD (high grade dysplasia) and in EAC (esophageal adenocarcinoma), 2) this expression correlates with disease progression towards EAC and 3) eradication of cells expressing stem cell markers occurs after therapy of EMR (endoscopic mucosal resection) or RFA (radiofrequency ablation) to eradicate BE with HGD and intramucosal adenocarcinoma and esophagectomy for EAC. We will test our hypotheses with the following aims: 1) To characterize the cell specific expression patterns of intestinal stem cell biomarkers in BE patients and correlate them with serum expression and disease progression, 2) To examine prospectively the effects of EMR, RFA or esophagectomy on the expression of stem cell biomarkers and the progression to EAC.
New tools are needed to 1) diagnose and 2) stage early esophageal squamous cell carcinoma (SCC) in order to improve outcomes of this frequent and lethal cancer. Optical coherence tomography (OCT) is an optical technique, which can image human tissue ex vivo and in vivo with a resolution around 30µm and with a depth of 1mm. Full-field optical coherence tomography (FFOCT) is a new modality, which allows to image an ex vivo specimen with a cellular resolution and to perform 3D reconstruction. This device has never been tested on esophageal specimens. Therefore, the aim of this non-interventional research is 1) to determine FFOCT diagnostic criteria for SCC and 2) to figure if FFOCT allows the staging of the depth of invasion in SCC. To achieve these goals, we will image ex vivo 10 specimens of endoscopic resection of SCC (endoscopic mucosal resection (EMR) and submucosal dissection (ESD)) using an FFOCT device and we will compare the results with histological analysis of these specimens.
Although recent global trends indicate reduced postoperative mortality after esophagectomy, major morbidity, in particular pulmonary, remains high, with considerable health and economic costs. In a recent modern international collaborative series of 2704 patients from high-volume centers, with an approximate equal mix of open and minimally invasive approaches, respiratory complications were evident in 28% of patients, pneumonia in 15%, and respiratory failure in 7%.1 In other series, respiratory failure is reported in up to 15% of patients and is the most common cause of mortality. Prediction of risk and prevention of respiratory morbidity is therefore of considerable importance, and in this context baseline assessment of respiratory physiology compliments clinical assessment, history and enhanced recovery pathways representing key elements of current patient management. In this study, which will include all prospective patients with locally advanced esophageal cancer treated at a National Center, pulmonary function will be systematically measured before and after neoadjuvant therapy. The investigators seek to evaluate the incidence of radiation induced lung injury (RILI), as well as subclinical changes in pulmonary physiology that may be linked to postoperative complications, and quality-of-life in survivorship, and to compare cohorts who received radiation therapy or chemotherapy alone, preoperatively.
The ENSURE study will comprise two phases. Phase 1: European multicenter survey of surveillance protocols after esophageal cancer surgery ENSURE questionnaire will be circulated to representatives from participating European countries. Phase 2: European multicenter retrospective observational study of the impact of postoperative surveillance protocols on oncologic outcome and HR-QL Phase 2 will constitute a retrospective observational study of patients undergoing treatment with curative intent for esophageal cancer at participating Centers from June 2009 to June 2015.
The study was designed to compare effectiveness and safety of the surgeries of Ivor-Lewis and Mckeown in patients with esophageal cancer
Cancer - including esophageal squamous cell cancer (ESCC) - is a disease of the elderly but little is known about the biology and progression of cancers in these patients. While most patients receive chemotherapy and/or chemo-radiation as first treatment, no treatment standard for following treatments has been established so far and there is a clear unmet medical need, especially for elderly patients. Hence, this study assesses the efficacy and safety of two experimental immunotherapy regimens (Nivolumab monotherapy or Nivolumab/Ipilimumab combination) in elderly patients with advanced esophageal squamous cell cancer.
In Siewert type II adenocarcinoma, the relationship between adenocarcinoma sub types and survival, histologic/biologic patterns related to the presence/absence of gastric greater curvature metastases, were investigated.
The multicenter real-world and propensity score matching comparative study was designed to explore the toxicity and effectiveness of Lobaplation or Cisplatin based adjuvant chemotherapy in esophageal carcinoma
