Metastases are involved in most cancer deaths. Evidence has suggested that cancer cell detachment from primary tumors might occur largely via the mechanism of epithelial-mesenchymal transition (EMT) activated by epigenetic events, but data addressing other possible triggers of detachment, particularly genetic mutations, have been limited. Using the Profile study of cancer genomics at Dana-Farber Cancer Institute, we examined somatic mutations in the EMT genes CDH1 in 5,106 primary carcinomas and CTNNB1 in 7,578 primary carcinomas across 13 anatomic sites: urinary bladder, breast, colon/rectum, endometrium, esophagus, kidney, lung, ovary, pancreas, prostate, skin (non-melanoma), stomach, and thyroid...

REVIEW
Mei Xu, Jia Luo
Heavy alcohol consumption has been associated with increased risk of several cancers, including cancer of the colon, rectum, female breast, oral cavity, pharynx, larynx, liver, and esophagus. It appears that alcohol exposure not only promotes carcinogenesis but also enhances the progression and aggressiveness of existing cancers. The molecular mechanisms underlying alcohol tumor promotion, however, remain unclear. Cancer stem cells (CSC), a subpopulation of cancer cells with self-renewal and differentiation capacity, play an important role in tumor initiation, progression, metastasis, recurrence, and therapy resistance...

The incidence of esophageal adenocarcinoma (EAC) is rising rapidly, and early detection within the precursor state of Barrett's esophagus (BE) is challenged by flat premalignant lesions that are difficult detect with conventional endoscopic surveillance. Overexpression of cell surface fibroblast growth factor receptor 2 (FGFR2) is an early event in progression of BE to EAC, and is a promising imaging target. We used phage display to identify the peptide SRRPASFRTARE that binds specifically to the extracellular domain of FGFR2...

BACKGROUND: Malignant dysphagia can result in poor nutritional status with severe weight loss. Rapid relief from dysphagia can be achieved with esophageal self-expanding metal stents (SEMSs), a minimally invasive method. In this study, we evaluated the usefulness of SEMSs for malignant dysphagia. METHODS: Between 2012 and 2015, 119 patients with malignant dysphagia underwent esophageal SEMS insertion with endoscopic assistance. Their demographics and clinical outcomes were collected...

Background: Obesity and diabetes mellitus are associated with lifestyle-related carcinogenesis. They are also risk factors of esophageal adenocarcinoma, but there are only a few reports on association between obesity/diabetes and development of squamous cell carcinoma in the oral cavity and esophagus. In this study, we therefore aimed to determine whether obesity and diabetes affect oral and esophageal carcinogenesis using model mice of obesity and diabetes, the Tsumura Suzuki obese diabetes (TSOD) and Tsumura Suzuki non-obesity (TSNO) control mice, which were treated with 4-nitroquinoline 1-oxide (4-NQO) to produce tongue and esophageal carcinomas...

The aim was to defect the exhaled nitric oxide (eNO) prediction value of symptomatic radioactive pneumonia (SRP). 64 cases of lung cancer or esophagus cancer, who had the primary radiotherapy (intensity-modulated radiation therapy), were included from 2015 June to 2016 January. During the following, the patients were divided: the symptomatic radiation pneumonia group (SRP, with the CTCAE v4.0 score > 2) and the asymptomatic radiation pneumonia group (ASRP, with CTCAE v4.0 score ≤ 1). All the patients were measured eNO before and at the end of thoracic radiotherapy and gain the posttherapy eNO value and the eNO ratio (posttherapy eNO value/pretherapy eNO value), then the predictive values of eNO toward SRP were measured using the receiver-operating characteristic (ROC)...

We report a 72-year-old woman who was initially diagnosed with locally advanced gastric cancer with involvement of the esophagus and pancreas. She received 3 courses of neoadjuvant chemotherapy(NAC)with docetaxel, cisplatin, and 5- fluorouracil(the DCF regimen)and achieved an excellent response. She underwent total gastrectomy with distal pancreatectomy, splenectomy, and D2 lymphadenectomy. Histological examination confirmed a pathological complete response. NAC chemotherapy can down stage/down size the disease and allow some patients to undergo curative radical surgery...

Esophageal squamous cell carcinoma (ESCC) in humans is a deadly disease associated with dietary zinc (Zn)-deficiency. In the rat esophagus, Zn-deficiency induces cell proliferation, alters mRNA and microRNA gene expression, and promotes ESCC. We investigated whether Zn-deficiency alters cell metabolism by evaluating metabolomic profiles of esophageal epithelia from Zn-deficient and replenished rats vs sufficient rats, using untargeted gas chromatography time-of-flight mass spectrometry (n = 8/group). The Zn-deficient proliferative esophagus exhibits a distinct metabolic profile with glucose down 153-fold and lactic acid up 1...

Orbital metastasis is an uncommon and atypical presentation of recurrent esophageal cancer that has been only seldom reported in literature. F-FDG PET/CT is routinely performed for staging and response assessment in patients with esophageal carcinoma. This case demonstrates use of follow-up FDG PET/CT scans in characterizing solitary metastatic disease in orbit and in evaluating response to therapy. It also highlights a key teaching point that postradiation-related inflammatory/infective changes may interfere in accurate assessment of PET/CT scan; however, frequently used clinical and radiological correlation may not be entirely sufficient to rule out pathological involvement...

The vast majority of esophageal adenocarcinoma cases are sporadic and caused by somatic mutations. However, over the last decades several families have been identified with clustering of Barrett's esophagus and esophageal adenocarcinoma. This observation suggests that one or more hereditary factors may play a role in the initiation of Barrett's esophagus and esophageal adenocarcinoma in these families. A Dutch family with clustering of Barrett's esophagus and esophageal adenocarcinoma was identified. Normal DNA obtained from the proband diagnosed with Barrett's esophagus was analyzed with SNP array and exome sequencing...

INTRODUCTION: Despite improvements in surgical techniques and treatments introduced into clinical practice, the overall survival of patients with esophageal squamous cell carcinoma remains low. Several epidermal growth factor receptor inhibitors are being evaluated in the context of clinical trials, but there is little evidence of effectiveness in real-world conditions. This study aimed at assessing the effectiveness of nimotuzumab combined with onco-specific treatment in Cuban real-life patients with locally advanced or metastatic esophageal squamous cell carcinoma...

BACKGROUND & AIMS: Esophageal atresia is rare, but improved surgical and intensive care techniques have increased rates of survival in children, so there are now many adults with this disorder. Many patients with esophageal atresia develop gastroesophageal reflux (GER), raising concerns about increased risk of Barrett's esophagus (BE; prevalence of 1.3%-1.6% in general population) and esophageal carcinoma. We assessed the prevalence of BE and esophageal carcinoma in this population. METHODS: We performed a prospective study of 289 patients with esophageal atresia at the Department of Gastroenterology and Hepatology at Erasmus MC University Medical Center in The Netherlands, from May 2012 through March 2017...

BACKGROUND: This study explored how to improve the surgical technique to reduce or avoid anastomotic leakage. METHODS: From January 2012 to December 2016, 101 consecutive patients with cancer of the esophagus or gastroesophageal junction underwent stapled gastroesophageal anastomosis. The procedure included creating a tube-type stomach, fixing an inserted anvil, inspecting mucosa-to-mucosa alignment in the lumen under direct vision after firing the stapler, and, if found, manually repairing a rupture of the mucous membrane of the anastomosis...

Esophageal cancer, the sixth most common cause of cancer globally, is characterized by the development of early systemic metastatic disease. Adenocarcinoma of the esophagus and gastroesophageal junction (GEJ) is more common in the West. Preoperative chemotherapy or chemoradiotherapy is employed for locally advanced disease with contemporary studies suggesting higher rates of curative resection and reduced rates of local recurrence with the combination of chemotherapy and radiation therapy given prior to surgery...

Esophageal cancer is the 8th most common cancer worldwide and the 6th most common cause of cancer-related death. Its two main subtypes, esophageal adenocarcinoma (EAC) and esophageal squamous cell carcinoma (ESCC), have varying incidences globally, but recent decades have seen a demonstrated rise of EAC in Western countries whereas ESCC remains highly prevalent in Eastern Africa, Central Asia, and China. Screening interventions have focused on using endoscopy to identify Barrett's esophagus (BE) as a precursor to EAC, and squamous cell dysplasia prior to onset of ESCC...

Radiotherapy plays a crucial role in the curative management of localized esophageal cancer, both as definitive and preoperative therapy. For definitive therapy, the standard radiation dose is 50.4 Gy in 28 fractions and should be delivered with concurrent chemotherapy. Chemoradiotherapy also has a wellestablished benefit in the preoperative setting, as established in the CROSS randomized trial. Radiation fields are typically generous, to account for subclinical extension of disease along the esophagus and to regional nodes...

Purpose: The efficiency of radiation delivery via volumetric modulated arc therapy (VMAT) is indisputable, but outcomes after VMAT for thoracic esophageal carcinoma are largely unknown. Methods and materials: We retrospectively analyzed 65 patients with thoracic esophageal cancer who received VMAT to 50.4 Gy (range, 45-50.4 Gy) with concurrent chemotherapy from November 2012 to March 2016 at a single tertiary cancer center. We then used propensity score matching to match these 65 patients with 130 other patients treated with step-and-shoot intensity modulated radiation therapy (ssIMRT) and concurrent chemotherapy...

Traditionally, reflux esophagitis was assumed to develop as a caustic, chemical injury inflicted by refluxed acid. Recently, however, studies in rats and humans suggest that reflux esophagitis develops as a cytokine-mediated inflammatory injury, with hypoxia inducible factor (HIF)-2α playing a major role. In response to the reflux of acid and bile, HIF-2α in esophageal epithelial cells becomes stabilized, thereby increasing production of pro-inflammatory cytokines that attract T lymphocytes and other inflammatory cells to damage the esophagus...
