UNLABELLED MicroRNAs are small noncoding RNAs that regulate gene expression by targeting messenger RNAs (mRNAs) through translational repression or RNA degradation. Many fundamental biological processes are modulated by microRNAs, and an important role for microRNAs in carcinogenesis is emerging. Because understanding the pathogenesis of viral-associated(More)
The purpose of this study was to clarify the relationship of the immunohistochemical expression of c-met, p53 and p21 with clinicopathological parameters and prognosis in gastric carcinomas. We analyzed specimens from 114 gastric cancer patients (median age 64 years, range: 33-86) who underwent gastrectomy with lymphadenectomy. Specimens were categorized(More)
Despite new therapeutic approaches patients with advanced oral squamous cell carcinoma still have a dismal prognosis. The main factor contributing to this problem is locoregional failure due to a lack of response to treatment. Several trials have proven the effect of neoadjuvant radiochemotherapy followed by radical surgery in comparison to primary surgery(More)
OBJECTIVE The purpose of this study was to evaluate the frequency of lymph node metastasis according to the depth of tumor infiltration of the mucosa and submucosa. BACKGROUND DATA Currently some endoscopists extend the indication for endoscopic mucosal resection in gastric cancer to the submucosa. However, the decision between endoscopic mucosectomy or(More)
PURPOSE Pancreatic cancer still has one of the worst prognoses in gastrointestinal cancers with a 5-year survival rate of 5%, making it necessary to find markers or gene sets that would further classify patients into different risk categories and thus allow more individually adapted multimodality treatment regimens. In this study, we investigated the(More)
BACKGROUND This study investigates response and prognosis after neo-adjuvant chemoradiation (CTx/RTx) in patients with advanced esophageal carcinoma, according to histological type. PATIENTS AND METHODS Patients with uT3 carcinoma of the esophagus treated with curative-intention esophagectomy from 1997 until 2006 were included in this retrospective(More)
Neoadjuvant treatment strategies have been developed to improve survival of patients with locally advanced esophageal cancer. Since only patients with major histopathological response benefit from this therapy, predictive markers are needed. We examined a panel of selected gene polymorphisms to predict response to neoadjuvant radiochemotherapy (cisplatin,(More)
We report a case in an elderly adult of a highly malignant liver tumor with blastoid features that resembled hepatoblastoma. A liver tumor with a diameter of 23 cm was removed in a 78-year-old woman. The tumor showed highly differentiated epithelial hepatocellular and poorly differentiated epithelial and mesenchymal components. The blastoid nature and(More)
Infection with high-risk human papillomavirus (HPV) type 16 is an independent risk factor for the development of oropharyngeal squamous cell carcinomas (OSCC). However, it is unclear whether viral integration is an essential hallmark in the carcinogenic process of OSCC and whether HPV integration correlates with the level of viral gene transcription and(More)
Virus-mediated gene delivery is restricted by the infectivity profile of the chosen vector. Targeting the vascular endothelium via systemic delivery has been attempted using peptides isolated in vitro (using either phage or vector display) and implicit reliance on target receptor expression in vivo. This has limited application since endothelial cells in(More)
