A case of esophageal carcinoma exclusively composed of adenocarcinoma simulating an esophageal gland duct in a 61-year-old man is presented. The tumor arose as a slightly elevated lesion in the middle intrathoracic esophagus. It was almost completely overlaid with non-neoplastic stratified squamous epithelial cells. Beneath the overlying surface epithelium, an adenocarcinoma that was bilayered in structure diffusely invaded both the mucosal and submucosal layers. Although the tumor consisted exclusively of adenocarcinomatous cells, a keratinizing squamous cell carcinoma component was focally observed...

Esophagitis, whether caused by acid reflux, allergic responses, graft-versus-host disease, drugs, or infections, is a common condition of the gastrointestinal tract affecting nearly 20% of the US population. The instigating agent typically triggers an inflammatory response. The resulting inflammation is a risk factor for the development of esophageal strictures, Barrett esophagus, and esophageal adenocarcinoma. Research into the pathophysiology of these conditions has been limited by the availability of animal and human model systems...

Esophageal metastasis from colorectal carcinoma is uncommon, and diagnosis of esophageal metastasis is difficult. We report a case of a 54-year-old woman with postoperative recurrence of rectal cancer metastasizing to the esophagus. She underwent rectectomy and adjuvant chemotherapy with fluorouracil, leucovorin plus oxaliplatin for stage IIIB rectal cancer. Three years later, she presented with dysphagia and cough. Computed tomography showed thickening of the esophagus wall, enlargement of the lymph nodes in the mediastinum and abdomen, and ground-glass opacities in the right lung...

BACKGROUND: Adenocarcinoma with enteroblastic differentiation is a subtype of alpha-fetoprotein (AFP) producing adenocarcinoma. This type of tumor is associated with a poor prognosis and is prone to metastasize. Esophageal adenocarcinoma with enteroblastic differentiation is extremely rare. CASE PRESENTATION: The patient was a 65-year-old woman who was referred to our hospital with dysphagia. Endoscopic examination revealed an elevated lesion 20mm in diameter at 17cm from the upper incisors...

The incidence of esophageal adenocarcinoma (EAC) has increased over the last few decades. With a known precursor lesion, Barrett's esophagus, this remains a target for screening and surveillance with the goal of detecting and providing curative treatment for early neoplasia. Areas covered: Current surveillance techniques rely on white light endoscopy and random tissue sampling which is time consuming, costly and prone to sampling error. Volumetric laser endomicroscopy (VLE), a second-generation optical coherence technology, has emerged as an advanced imaging modality with the potential to improve dysplasia detection, surveillance and subsequently prevent esophageal adenocarcinoma...

Although metaplasias have always attracted because of their strangeness, it is now clear they represent precursors for some of the most intractable human cancers. Despite this notoriety, they remain curiously understudied, and even their origins have been the subject of acrimonious debate stretching back to Virchow in the 19th century. Barrett's esophagus, with its high incidence, easy endoscopic access, and strong link to esophageal adenocarcinoma, would seem an ideal opportunity to address the origin problem...

Barrett's esophagus is the metaplastic change of the squamous epithelium lining the distal esophagus into an intestinalized columnar epithelium that predisposes to esophageal adenocarcinoma development. The cell that gives rise to Barrett's esophagus has not been identified definitively, although several sources for the Barrett's esophagus cell of origin have been postulated. One possible source is a fully differentiated squamous epithelial cell or a squamous epithelial progenitor or stem cell native to the esophagus that, through molecular reprogramming, either transdifferentiation or transcommitment, could give rise to an intestinalized columnar cell...

The origin of the progenitor cell for Barrett's esophagus remains a major unsolved mystery. Understanding the source of this progenitor may improve strategies to prevent the development of esophageal adenocarcinoma. Esophageal submucosal glands (ESMGs) and ducts may serve as a potential source of progenitor cells that respond to esophageal injury. Through the use of human histologic and molecular analysis, ESMGs and ducts have been described in physical continuity with areas of columnar esophagus, and shared mutations have been described between ESMG ducts and Barrett's esophagus...

BACKGROUND AND AIMS: Esophageal adenocarcinoma develops in the setting of gastroesophageal reflux and columnar metaplasia in distal esophagus. Columnar metaplasia arising in gastroesophageal reflux models has developed in rat; however, gastroesophageal reflux models in mice have not been well-characterized. METHODS: One hundred thirty-five C57Bl/6J mice aged 8 weeks old were divided into the following operations: esophagogastrojejunostomy (side-to-side) (EGJ), esophageal separation and esophagojejunostomy (end-to-side) (EJ), and EJ and gastrectomy (end-to-side) (EJ/TG)...

Thomas J Watson
Endoscopic therapies have become the standard of care for most cases of Barrett's esophagus with high-grade dysplasia or intramucosal adenocarcinoma. Despite a rapid and dramatic evolution in treatment paradigms, esophagectomy continues to occupy a place in the therapeutic armamentarium for superficial esophageal neoplasia. The managing physician must remain cognizant of the limitations of endoscopic approaches and consider surgical resection when they are exceeded. Esophagectomy, performed at experienced centers for appropriately selected patients with early-stage disease can be undertaken with the expectation of cure as well as low mortality, acceptable morbidity, and good long-term quality of life...

Cryotherapy or cryoablation involves the freezing of tissues to destroy unwanted tissue or to control bleeding. Endoscopic cryotherapy has been developed for gastrointestinal application by through-the-scope noncontact delivery of compressed carbon dioxide gas or liquid nitrogen (cryospray) or contact balloon cryoablation. The mechanism of cryotherapy ablative effects includes immediate injury as well as coagulation necrosis occurring over several hours and days, unlike heat-based thermal ablation. This article reviews the basis, technique, safety, efficacy, and durability for the use of endoscopic cryotherapy in Barrett's esophagus and esophageal adenocarcinoma...

In the last decade, radiofrequency ablation in combination with endoscopic mucosal resection has simplified and improved the treatment of Barrett's esophagus. These treatments not only reduced the progression of dysplastic Barrett's esophagus to esophageal adenocarcinoma but also decreased treatment-related complications. More recent data from larger series with extended follow-up periods are emerging to refine expectations in patients treated with radiofrequency ablation. Although most patients achieve eradication of neoplasia and intestinal metaplasia, in the long-term a substantial portion of patients develop recurrent disease...

Gastroenterology society guidelines recommend endoscopic surveillance as a means to detect early stage cancer in Barrett's esophagus. However, the incidence of esophageal adenocarcinoma in Western countries continues to increase, suggesting that this strategy may be inadequate. Current surveillance methods rely on the endoscopist's ability to identify suspicious areas of Barrett's esophagus to biopsy, random biopsies, and on the histopathologic diagnosis of dysplasia. This review highlights the challenges of using dysplasia to stratify cancer risk and addresses the development and use of molecular biomarkers and in vivo molecular imaging to detect early neoplasia in Barrett's esophagus...

Guidelines for the screening and surveillance of Barrett's esophagus continue to evolve as the incidence of esophageal adenocarcinoma increases, identification of individuals at highest risk for cancer improves, and management of dysplasia evolves. This article reviews related studies and economic analyses. Advances in diagnosis offer promising strategies to help focus screening efforts on those individuals who are most likely to develop esophageal adenocarcinoma.

Barrett's esophagus (BE) predisposes patients to esophageal adenocarcinoma. 3 to 6% of individuals with gastro-esophageal reflux disease are estimated to have BE but only 20 to 25% of BE patients are currently diagnosed. The current gold standard for diagnosis of BE is per-oral upper GI endoscopy. As this is not suitable for large-scale screening, a number of alternative methods are currently being investigated: transnasal and video capsule endoscopy, endomicroscopy, cell collection devices like the cytosponge and biomarkers...

Despite the availability of safe and effective endoscopic treatment of Barrett's esophagus (BE)-related dysplasia and neoplasia, the incidence and mortality from esophageal adenocarcinoma (EAC) have continued to increase. This likely stems from the large population of patients that develop EAC outside of a BE screening and surveillance program. Identification of BE with screening followed by enrollment in an appropriate surveillance/risk stratification program could be a strategy to address both the incidence of and mortality from EAC...

Barrett's esophagus and esophageal adenocarcinoma diagnoses have increased markedly in recent decades. Recent research with patients diagnosed with Barrett's esophagus (the only known precursor for esophageal adenocarcinoma) and esophageal adenocarcinoma has identified several modifiable and nonmodifiable potential risk factors. Consistent risk factors for both disorders include increasing age, male sex, white non-Hispanic race/ethnicity, gastroesophageal reflux disease, lack of infection with Helicobacter pylori, smoking, abdominal obesity, and a Western diet...

The rarity of primary small cell carcinoma of the esophagus (PSCE) has limited the clinical feature and survival analysis with large sample size. Tissue chromogranin A (CgA) protein expression has been reported to be a useful biomarker for diagnosing PSCE. Interestingly, recent studies have indicated tissue CgA as a significant prognostic marker in multiple human cancers, but without PSCE. The present study, thus, was undertaken to characterize the clinicopathological changes and to evaluate the associations of tissue CgA expression with clinical response on Chinese PSCE patients...

Esophageal injury is a risk factor for diseases such as Barrett's Esophagus (BE) and Esophageal Adenocarcinoma. In order to improve understanding of signaling pathways associated with both normal and abnormal repair, animal models are needed. Traditional rodent models of esophageal repair are limited by the absence of esophageal submucosal glands (ESMGs), which are present in human esophagus. Previously, we identified acinar ductal metaplasia in human ESMGs in association with both esophageal injury and cancer...
