A 61-year-old woman was introduced for consultation with a chief complaint of frequent vomiting. CT revealed a pancreatic body cancer approximately 40mm in size; an invading stenosis from the horizontal part of the duodenum to the jejunum, superior mesenteric artery, and portal vein, splenic vein obstruction, lymphadenopathy, and some ascitic fluid. We diagnosed a passage disorder due to the invasive stenosis from the horizontal part of the duodenum of the pancreatic body cancer to the jejunum, and subsequently performed a duodenum and jejunum bypass operation...

Long noncoding RNAs (lncRNAs) or exosomes have recently been shown to play vital regulatory or communication roles in cancer biology. However, the roles and mechanisms of exosomal lncRNAs in tumor invasion or metastasis of pancreatic ductal adenocarcinoma (PDAC) remain unknown. In this study, we aimed to investigate the detailed roles and mechanisms of tumor-generated exosomes in progression and metastasis of PDAC in vitro and in vivo. We identified a lncRNA-Sox2ot from exosomes of highly invasive PDAC cells, and analyzed the expression of Sox2ot in the plasma samples and found that the plasma exosomal Sox2ot expression was high and correlated with TNM stage and overall survival rate of PDAC patients...

Pancreatic cancer continues to represent one of the leading causes of cancer-related morbidity and mortality in the developed world. Over the past decade, novel systemic therapy combination regimens have contributed to clinically meaningful and statistically significant improvements in overall survival as compared to conventional monotherapy. However, the prognosis for most patients remains guarded secondary to the advanced stages of disease at presentation. There is growing consensus that outcomes can be further optimized with the use of predictive and prognostic biomarkers whereby the former can be enriching for patients who would benefit from therapies and the latter can inform decision-making regarding the need and timing of advanced care planning...

Despite the genomic characterization of pancreatic cancer (PC), marked advances in the development of prognosis classification and novel therapeutic strategies have yet to come. The present study aimed to better understand the genomic alterations associated with the invasive phenotype of PC, in order to improve patient selection for treatment options. A total of 30 PC samples were analysed by either whole transcriptome (9 samples) or exome sequencing (21 samples) on an Illumina platform (75X2 or 100X2 bp), and the results were matched with normal DNA to identify somatic events...

Surgery for the treatment of pancreatic cancer remains the gold standard, however, the identification of the vascular supply of the pancreas and the nearby organs remains a crucial difficulties in a curative resection. During pancreatic head resection for carcinoma dissection of regional arterial vasculature is mandatory. Normal coeliac and hepatic arterial anatomy occurs in ~50-70% of patients and multiple variations have been described. Knowledge of multiple arterial anomalies is essential in hepato-pancreatico-billary surgery to avoid unnecessary complications...

Pancreatic cancer has a high mortality rate due to late diagnosis and the tendency to invade surrounding tissues and metastasize at an early stage. A molecular imaging agent that enables both pre-surgery antigen-specific positron emission tomography (immunoPET) and intra-operative near-infrared fluorescent (NIRF)-guidance could benefit diagnosis, staging and surgical resection of pancreatic cancer, which remains the only curative treatment. Methods: A dually labeled probe was developed based on A2 cys-diabody (A2cDb) targeting the cell surface antigen prostate stem cell antigen (PSCA) that is expressed in a majority of pancreatic cancers...

BACKGROUND/AIMS: Krüppel-like factor 4 (KLF4), a member of the KLF family of zinc finger transcription factors, has been identified as a tumor suppressor gene in a variety of tumors. However, the molecular mechanisms by which KLF4 inhibits epithelial-to-mesenchymal transition (EMT) and metastasis in pancreatic cancer remain unclear. METHODS: KLF4 expression in pancreatic cancer was analyzed using public datasets (Oncomine and The Cancer Genome Atlas). The expression of KLF4, caveolin-1 (Cav-1), E-cadherin, and vimentin, and their correlations with clinicopathological characteristics were evaluated by immunohistochemistry in pancreatic cancer tissues...

Pancreatic cancer is the twelfth most common cancer in the United States, representing 3.2% of all new cancer cases. While composing a small percentage of cancer diagnoses, pancreatic cancer is amongst the most lethal carcinomas, with an overall 5-year survival of 8.2% and incidence rates almost equivocal to death rates. By the time of diagnosis, a majority of patients will present with advanced stage disease. For patients with resectable disease, the estimated overall survival (OS) remains low at 20% as most will develop metastatic disease within 5 years...

AIMS: New chemotherapeutic agents prolong survival of patients with pancreatic ductal adenocarcinoma (PDAC). Although their incidence is rising, patients with end-stage renal disease (ESRD) requiring hemodialysis (HD) are not included in the phase III trials evaluating the effects of these chemotherapies. Many experts recommend applying chemotherapy after HD using a reduced dose. Alternatively, the concept of prior dosing allows for the application of dialyzable chemotherapeutic drugs using a normal dose, with an HD followed shortly after to mimic normal renal function...
