Ernst J Kuipers, Manon C Spaander
Barrett's esophagus (BE) is a very common condition. We have obtained fairly profound knowledge of the natural history of this condition. This results from many cross-sectional and cohort studies, many describing patients undergoing long-term surveillance. Their consent to use their clinical data has improved our knowledge to the benefit of these same and other patients. The prevalence of BE increases with age both in men and in women. This increase starts at a younger age in men than in women. The incidence of high-grade dysplasia and cancer in BE depends on segment length, gender, and age...

BACKGROUND & AIMS: There is limited information on contemporary incidence rates and trends, by race, ethnicity, and age, for major subtypes of esophageal and gastric cancer in the United States. We examined the most recent nationwide incidence data for esophageal squamous cell carcinoma, esophageal adenocarcinoma (EAC), gastric cardia adenocarcinoma (GCA), and gastric non-cardia adenocarcinoma (GNCA) by race, ethnicity, and age in the United States. METHODS: Average contemporary incidence rates (2010-2014) and annual percent changes in rates (from 1997 through 2014) by race, ethnicity, and age were calculated for each cancer subtype using nationwide data compiled by the North American Association of Central Cancer Registries...

BACKGROUND: Endoscopic eradication therapy (EET) is highly effective in treating dysplastic Barrett's esophagus (BE). Current surveillance intervals after complete remission of intestinal metaplasia (CRIM) are based on expert opinion. We performed a meta-analysis to compare BE detection in the first year to the subsequent ones METHODS: We searched MEDLINE, EMBASE, Scopus and Cochrane Central Register of Controlled Trials through 1 August 2017 for studies reporting IM and neoplasia detection after CRIM...

Paclitaxel is a powerful chemotherapeutic drug, used for the treatment of many cancer types, including esophageal adenocarcinomas (EAC). Autophagy is a lysosome-dependent degradation process maintaining cellular homeostasis. Defective autophagy has been implicated in cancer biology and therapy resistance. We aimed to assess the impact of autophagy on chemotherapy response in EAC, with a special focus on paclitaxel. Responsiveness of EAC cell lines, OE19, FLO-1, OE33 and SK-GT-4, to paclitaxel was assessed using Alamar Blue assays...

BACKGROUND: Minimally invasive methods have been described to detect Barrett's esophagus (BE), but are limited by subjectivity and suboptimal accuracy. We identified methylated DNA markers (MDMs) for BE in tissue and assessed their accuracy on whole esophagus brushings and capsule sponge samples. METHODS: Step 1: Unbiased whole methylome sequencing was performed on DNA from BE and normal squamous esophagus (SE) tissue. Discriminant MDM candidates were validated on an independent patient cohort (62 BE cases, 30 controls) by quantitative methylation specific PCR (qMSP)...

Controversy remains regarding the optimal resection approach for Siewert type II adenocarcinoma of the esophagogastric junction (EGJ). Furthermore, an esophageal diverticulum, although rare, can complicate surgical procedures. Herein, we report a case of EGJ adenocarcinoma with an esophageal diverticulum that was treated using the minimally invasive abdominal and left thoracic approach (MALTA). A 72-year-old man, with EGJ adenocarcinoma and an epiphrenic diverticulum on esophagogastroduodenoscopy underwent endoscopic submucosal dissection...

We reported the first case of inoperative thymic adenocarcinoma successfully palliative treated by the double-stent procedure. In a patient who expressed stridor, computed tomography was done and necrotic mediastinal mass, which protrudes into a trachea, was demonstrated. Fiberoptic bronchoscopy showed tracheal infiltration and 70% stenosis; therefore, surgical resection was inapplicable. Recanalization with repeated argon plasma coagulation and debridement of necrotic mass was performed, followed by placement of the endotracheal stent, radiotherapy, and chemotherapy...

BACKGROUND & AIMS: Immune checkpoint inhibition may affect growth or progression of highly aggressive cancers, such as esophageal adenocarcinoma (EAC). We investigated the regulation of expression of major histocompatibility complex, class 1 (MHC-I) proteins (encoded by HLA-A, HLA-B, and HLA-C) and the immune response to EACs in patient samples. METHODS: We performed quantitative PCR array analyses of OE33 cells and OE19 cells, which express different levels of the ATP binding cassette subfamily B member 1 (TAP1) and TAP2, required for antigen presentation by MHC-I, to identify microRNAs that regulate their expression...

OBJECTIVES: Epidemiological studies of Helicobacter pylori infection and risk of Barrett's esophagus (BE) have reported conflicting results. We examined the association between H. pylori infection and BE and sought to determine whether the association is mediated by gastroesophageal reflux disease (GERD) and to identify potential effect modifiers. METHODS: We used individual level data from 1308 patients with BE (cases), 1388 population-based controls, and 1775 GERD controls in the Barrett's and Esophageal Adenocarcinoma Consortium (BEACON)...

Patient selection is suboptimal in most studies focused on identifying biological markers for neoplastic progression in Barrett's esophagus (BE). This study aims to describe a stringently selected community-based case-control cohort of non-dysplastic BE (NDBE) patients who progressed to high-grade dysplasia (HGD) or esophageal adenocarcinoma (EAC) and BE patients who never progressed to be used for future biomarker studies. We identified all patients referred for endoscopic work-up of BE neoplasia at three tertiary referral centers for treatment of BE neoplasia between 2000 and 2013...

Background . The outcome of patients with adenocarcinoma of the esophagogastric junction (AEG) remains poor. The programmed cell-death-protein-1 (PD-1), a co-inhibitory receptor primarily expressed by T-cells, represents a potential new therapeutic target. PD-1, PD-1 ligand 1 (PD-L1), and PD-L2 expression have all been described as prognostic factors in a variety of cancers. Their expression patterns in AEG, however, are poorly understood. We analyzed PD-L1, PD-L2 and PD-1 expression by tumor-infiltrating lymphocytes (TILs) and cancer-cells in tumor-biospecimens in AEG-patients...

Lung and esophageal development and organogenesis involve a complex interplay of signaling pathways and transcriptional factors. Once the lung and esophagus do separate, their epithelial proliferation and differentiation programs share certain common properties that may fuel adaptive responses to injury and subsequent regeneration. Lung and esophageal tissue organogenesis and regeneration provide perspectives on squamous cell cancers and adenocarcinomas in each tissue.

Esophageal adenocarcinoma (EAC) is a molecularly heterogeneous disease that is rising rapidly in incidence and has poor prognosis. We developed a heterobivalent peptide to target detection of early Barrett's neoplasia by combining monomer heptapeptides specific for either EGFR or ErbB2 in a heterodimer configuration. The structure of a triethyleneglycol linker was optimized to maximize binding interactions to the surface receptors on cells. The Cy5.5-labeled heterodimer QRH*-KSP*-E3-Cy5.5 demonstrated specific binding to each target and showed 3-fold greater fluorescence intensity and 2-fold higher affinity compared with either monomer alone...

Due to the ineffectiveness of chemoradiation and targeted therapy in esophageal anticancer care and the subsequent low survival rates, we constructed a high throughput method to discover and investigate new markers with prognostic, diagnostic, and therapeutic clinical utility. This was accomplished by developing a quick, inexpensive, and dependable platform to simultaneously quantify thousands of proteins which subsequently revealed novel markers involved in the pathogenesis of esophageal adenocarcinoma (EAC) via discovery mass spectrometry paired with conservative biostatistics...

Extent of mediastinal lymphadenectomy during esophagectomy is clearly different between two representative countries of the Eastern and Western world, such as Japan and the Netherlands. In Japan, a clear policy is the standard complete two- or three-field type of lymphadenectomy whereas, in the Netherlands, a limited form is usually carried out. Reasons for these differences can be found in the different types of tumor, 80% of adenocarcinomas in the West and almost 95% of squamous cell cancer in Japan. Moreover, location of the tumors, distally located in the Netherlands whereas, in Japan, the majority are located in the middle and proximal thoracic esophagus...

Hereditary spastic paraplegia (HSP), also known as familial spastic paraparesis or Strümpell-Lorrain disease, is a rare group of inherited disorders characterized by progressive spastic weakness in the lower limbs due to axonal degeneration of the corticospinal tracts. We describe the anesthetic management of a 52-year-old man with HSP who underwent an Ivor-Lewis esophagectomy for esophageal adenocarcinoma. This is the first report in the literature describing the anesthetic management of a patient with HSP successfully undergoing complex thoracoabdominal surgery...
