PURPOSE The purpose is to characterize alterations of the annexin I gene, its mRNA, and protein expression in esophageal squamous cell carcinoma. EXPERIMENTAL DESIGN Fifty-six cases of esophageal squamous cell carcinoma were analyzed using four microsatellite markers flanking the annexin I gene (9q11-q21) to identify loss of heterozygosity. In addition, we performed (a) single-strand conforma...
Introduction. Gastrointestinal stromal tumors of the esophagus are rare. Case Presentation. This is a case of a 50-year-old male patient who was referred to our department complaining of atypical chest pain. A chest computed tomographic scan and endoscopic ultrasound revealed a submucosal esophageal tumor measuring 5 cm in its largest diameter. Suspecting a leiomyoma, we performed enucleation v...
The development of new sensitive immunohistochemical methods allows the detection of single tumor cells or cell clusters in lymph nodes staged as tumor free on routine histologic examination. The prevalence and prognostic impact of these so-called lymph node ‘micrometastases’ has been studied in a variety of different tumor types. Only limited and still somewhat conflicting data are available f...
Esophageal cancer incidence is increasing and has few treatment options. In studying receptor tyrosine kinases associated with esophageal cancers, we have identified EPHB4 to be robustly overexpressed in cell lines and primary tumor tissues. In total, 94 squamous cell carcinoma, 82 adenocarcinoma, 25 dysplasia, 13 Barrett esophagus, and 25 adjacent or unrelated normal esophageal tissues were ev...
BACKGROUND Adenocarcinoma of the distal esophagus and gastric cardia are defined by the relationship of its epicenter to the gastro-esophageal junction, which is presently defined as the end of the tubular esophagus. We have recently suggested that the true gastro-esophageal junction is best defined by the proximal limit of gastric oxyntic mucosa. AIM To reclassify adenocarcinomas of this reg...
although esophageal liposarcoma is an extremely rare tumor, liposarcoma is the most common soft tissue sarcoma in adults. liposarcoma is currently classified into the types of well-differentiated, myxoid, round cell, pleomorphic and dedifferentiated liposarcoma. up to now only a few cases of esophagus liposarcoma have been described in the world literature. we describe a myxoid type liposarcoma...
background: human cripto-1, a member of the egf-cfc family, is involved in embryonic development, embryonic stem cell maintenance, and tumor progression. it also participates in multiple cell signaling pathways including wnt, notch, and tgf-β. remarkably, it is expressed in cancer stem cell (csc) compartments, boosting tumor cell migration, invasion, and angiogenesis. although cripto-1 is overe...
PURPOSE To report toxicity and early survival data for IDEAL-CRT, a trial of dose-escalated concurrent chemoradiotherapy (CRT) for non-small cell lung cancer. PATIENTS AND METHODS Patients received tumor doses of 63 to 73 Gy in 30 once-daily fractions over 6 weeks with 2 concurrent cycles of cisplatin and vinorelbine. They were assigned to 1 of 2 groups according to esophageal dose. In group ...
Multiple primary malignancies are not rare. While metachronous triple cancers are rare and a triple tumor case involving maxillary sinus and tympanic membrane is exceptionally rare. We present such an extremely rare case with the index tumor of adenoid cystic carcinoma of the maxillary sinus and 14 years later esophageal cancer was observed as a metachronous tumor. One year after esophageal can...
We report a case of esophageal squamous cell carcinoma (SCC) with marked eosinophil infiltration which was identified postoperatively in the esophageal wall in areas not surrounding the SCC. The eosinophil infiltration was seen in the submucosa, muscle and adventitia, but not in the mucosa. Eosinophilic esophagitis (EoE) is a pathological condition defined as eosinophil infiltration within the ...
