A 76-year-old woman complained of painful dysphagia and loss of weight. Esophagoscopy results were negative, whereas computed tomography (CT) disclosed a 25-mm mediastinal tumor without a connection to the esophagus. A diagnosis of nutcracker esophagus was made on high-resolution esophageal manometry. Peroral endoscopic esophageal myotomy failed to improve the symptoms. Right video thoracoscopy allowed resection of the tumor, which looked like a neurogenic tumor of the posterior mediastinum that developed from the right vagus nerve...

Five-year survival rate of esophageal squamous cell carcinoma (ESCC) patients treated with radiotherapy is <20%. Our study aimed to investigate whether cancer-associated fibroblasts (CAFs), one major component of tumor microenvironment, were involved in tumor radioresistance in ESCC. By use of human chemokine/cytokine array, human chemokine CXCL1 was found to be highly expressed in CAFs compared with that in matched normal fibroblasts. Inhibition of CXCL1 expression in CAFs significantly reversed CAF-conferred radioresistance in vitro and in vivo...

Aberrantly expressed microRNAs contribute to the initiation and progression of human cancer. MiRNA-187 has been reported in nasopharyngeal, renal, pancreatic, prostate, and esophageal cancer, and acts as a tumor suppressor or oncogene. However, the underlying function of miRNA-187 in cervical cancer remains largely unexplored. In the present study, we demonstrated significantly miRNA-187 down-regulation in cervical cancer tissues and cell lines compared to their normal counterparts. Kaplan-Meier analysis revealed that decreased miRNA-187 was closely associated with shorter overall survival and relapse-free survival...

Anatomical variants of the celiac trunk (CT) branches and especially these of hepatic arteries (HAs) are among the most common variants of the arterial tree. The knowledge of the wide variability in hepatic arterial supply is of paramount importance in hepatobiliary, pancreatic, gastric, and esophageal surgery, as well as in liver transplantations. The purpose of this case report is to describe a rare variant discovered during abdominal dissection of a 74-year-old male cadaver of Greek origin, in which the common hepatic artery was absent and its branches, the proper hepatic artery (PHA) and the gastroduodenal artery (GDA) had an aberrant and separate origin...

The determination of prognosis in patients with esophageal squamous cell carcinoma (ESCC) is primarily based on staging according to the TNM-classification, whereas conventional grading is of minor clinical importance because of its deficiencies in prognostic patient stratification. Recently, a novel, highly prognostic grading scheme based on budding activity and cell nest size has been proposed for squamous cell carcinoma (SCC) of both pulmonary as well as oral origin. In order to investigate the utility and transferability of this approach to ESCC, we evaluated budding activity and cell nest size, as well as other histomorphologic characteristics, in a cohort of 135 primarily resected tumors and correlated the results with clinicopathologic and outcome parameters...

REVIEW
Adrian G Murphy, Ronan J Kelly
The connection between inflammation and malignancy has long been recognized in gastric and esophageal cancers. Given the considerable success of immune checkpoint inhibitors in other tumor types, for example, lung cancer and melanoma, much attention is being paid to furthering their role in gastric and esophageal cancers. The Cancer Genome Atlas has provided further details of the molecular heterogeneity of these tumors, which may help predict responsiveness to immune checkpoint inhibitors. This article discusses the rationale for investigating these agents in gastroesophageal cancer and summarizes the relevant clinical trial data and ongoing studies...

REVIEW
Thomas Hayes, Elizabeth Smyth, Angela Riddell, William Allum
Gastric and esophageal tumors have a poor prognosis; approximately 15% of patients are alive at 10 years following diagnosis. Surgical resection plus adjunctive chemotherapy or chemoradiotherapy is curative in approximately 50% of patients with operable disease, but is also associated with significant morbidity. Therefore, accurate preoperative staging is required to spare patients unnecessary toxicity and futile surgery. This review evaluates the sensitivity and specificities of the modalities used to stage patients with gastroesophageal cancer...
