OBJECTIVE: The aim of this study was to assess the impact of chemoradiation on the immune microenvironment to influence and optimally design future neoadjuvant clinical trials. SUMMARY BACKGROUND DATA: Programmed death (PD)-1 inhibitors in metastatic gastroesophageal cancer have demonstrated response rates of approximately 25% in programmed death ligand-1 (PD-L1+) tumors. Unfortunately, the majority of patients do not respond. Therefore, a rationale strategy of combining immunotherapeutic agents with chemoradiation in earlier stage esophageal cancer may prevent metastatic disease in patients...

High levels of angiogenesis are associated with poor prognosis and a highly invasive phenotype in esophageal squamous carcinoma. C-C chemokine receptor type 7 (CCR7) is overexpressed in multiple tumor types and has been suggested to act as an oncogene and pro-angiogenic factor. This study aimed to elucidate the effect of CCR7 on the angiogenic capacity of esophageal squamous carcinoma cells in vitro. Expression of CCR7 in esophageal squamous carcinoma cell lines and normal human esophageal epithelial cell line was examined by western blotting and quantitative real-time PCR...

<br>Introduction: 18FDG PET-scanner positivity correlates with poor prognosis in neuroendocrine neoplasms (NEN). Glucose transporter 1 (GLUT1) and carbonic anhydrase 9 (CA9) are markers of agressivity in tumors. Together with pVHL, they are involved in tumor cell metabolism via the hypoxia-inducible factor (HIF) signaling pathway. The aim of this study was to compare, in a series of well-differentiated neuroendocrine tumors (NET), the 18-FDG uptake and expression of proliferation marker Ki-67, GLUT-1, CA9 and pVHL...

Progestin and adipoQ receptor family member 3 (PAQR3) has exhibited anticancer activity in multiple malignancies. However, its expression and function in esophageal squamous cell carcinoma (ESCC) is still elusive. In this work, we examined the expression of PAQR3 in 40 surgically resected ESCC specimens and their adjacent normal tissues. The expression of PAQR3 in ESCC cell lines was measured after treatment with the demethylating agent 5-aza-2'-deoxycytidine (5-Aza-CdR). The effects of overexpression of PAQR3 on cell proliferation, colony formation, invasion, and tumorigenesis were investigated...

Effective treatments for esophageal squamous cell carcinoma (ESCC), one of the most common cancers in China, are lacking. Longikaurin A (LK-A), an ent-kauranoid diterpenoid isolated from Isodon ternifolius, has been shown to have potent cytotoxic effects on ESCC cells both in vivo and in vitro, mainly by inducing apoptosis. In this study, LK-A inhibited ESCC cells viability and induced G2/M cell cycle arrest. Moreover, LK-A was also highly effective in a KYSE-30 xenograft nude mouse model. Treatment with Z-VAD(OMe)-FMK partially attenuated LK-A-induced apoptosis...

An endoscopic examination revealed a mass in the distal esophagus of a 9-year-old intact male bulldog. Histopathologically, the mass was composed of cuboidal to columnar neoplastic epithelial cells and extended from the squamous epithelium of the esophageal mucosa, indicating that the tumor was derived from Barrett's esophagus. Moreover, highly atypical foci that exhibited a cribriform pattern and high mitotic indices were also observed. The epithelial cells on the surface of the lesion often produced mucus that was positive for Alcian blue and immunohistochemically positive for MUC5AC...

We developed fibroblast activation protein α (FAPα)-sensitive magnetic iron oxide nanoparticles (MNPs) by conjugating a substrate-reporter tandem peptide as a synthetic biomarker to the surface of MNPs (marker-MNPs). In vitro, the marker-MNPs showed stability when treated with serum or urine and exhibited high susceptibility and specificity for FAPα enzyme and 3T3/FAPα cell line. Furthermore, the marker-MNPs were administered to esophageal squamous cell carcinoma xenograft tumor mice; they reached the tumor tissues in the mice, where they were cleaved effectively by the local overexpressed FAPα to release the reporter peptide and filter it into the urine...

Esophageal squamous cell carcinoma (ESCC) is one of the most common malignancies worldwide and occurs at a relatively high frequency in People's Republic of China. However, the molecular mechanism underlying ESCC is still unclear. In this study, the mRNA and long non-coding RNA (lncRNA) expression profiles of ESCC were downloaded from the Gene Expression Omnibus database, and then differential co-expression analysis was used to reveal the altered co-expression relationship of gene pairs in ESCC tumors. A total of 3,709 mRNAs and 923 lncRNAs were differentially co-expressed between normal and tumor tissues, and we found that most of the gene pairs lost associations in the tumor tissues...

BACKGROUND AND AIMS: Subepithelial esophageal tumors (SETs) are frequent incidental findings. Although symptomatic tumors are surgically or endoscopically resected, there is no consensus on the management of asymptomatic esophageal leiomyomas. METHODS: Appropriate ICD-9 codes followed by medical record review were used to identify patients with SETs from January 1992 to March 2017, with abstraction of basic demographics, surveillance intervals, and mortality. Patients were contacted to complete a phone questionnaire to assess follow-up and complete the validated brief esophageal dysphagia questionnaire (BEDQ)...

Esophageal cancer is the eighth most common malignant tumor worldwide, and the number of incidences of esophageal adenocarcinoma is increasing in the Western world. Despite improvements in perioperative treatment, the overall survival rate of patients with esophageal adenocarcinoma remains poor. Breast cancer type 1 susceptibility protein (BRCA1)-associated protein (BAP1) is located on chromosome 3p21, and it is an enzyme with ubiquitin carboxyl hydrolase activity that regulates cell growth. It interacts with BRCA1, and the nuclear localization of BAP1 is required for its tumor suppressor function...
