Pancreatic ductal carcinoma (PDC) is one of the major causes of cancer-associated mortality globally due to its high potential for distant metastasis. To understand hematogenous metastasis, the molecular expression profiles of weak metastatic PDC cell subline BxPC-3 and highly liver-metastatic cell subline LM-BxPC-3 were compared, and zinc finger protein 185 (ZNF185) was identified as a molecule that is upregulated in LM-BxPC-3 cells. The aim of the present study was to evaluate the clinicopathological significance of ZNF185 in PDC...

Pancreatic cancer, one of the most common cancers globally, is the fourth most common cause of cancer-associated mortality in the USA. The 5-year relative survival rate for patients with pancreatic cancer is ~5% and the median survival time is only 6 months. The poor prognosis is mainly due to early and aggressive local invasion and metastasis, as well as dissemination of the pancreatic cancer cells. The present study demonstrated that microRNA-452 (miR-452) was markedly downregulated in pancreatic cancer tissues, particularly in metastatic tumors and pancreatic cancer cell lines...

Pancreatic cancer is characterized by increased hyperplasia of fibrotic tissue, termed desmoplasia, and lymph node metastasis is an independent prognostic factor in this disease. However, there are no reports focused on desmoplasia in pancreatic cancer lymph node metastases. The present study evaluated a range of factors and investigated their association with poor prognosis in pancreatic cancer cases with lymph node metastasis, including the degree of desmoplasia in lesions. To identify the poor prognostic factors associated with lymph node metastasis, the present study retrospectively reviewed the clinical data of 65 patients with lymph node metastases that underwent surgical pancreatic cancer resection between 2007 and 2012 at a single institution...

The incidence of pancreatic cancer has been obviously increasing in China over the last decade, however, those patients with advanced pancreatic cancer are suffering from limited treatment strategies and poor clinical prognosis. Chemotherapy improved the overall survival of cases with advanced pancreatic cancer to 8-11 months, and erlotinib brought an additional survival of only 10 days. In this article, the recent progresses on advanced pancreatic cancer were reviewed at the genetic and molecular sub-typing levels, and corresponding clinical transformation studies summarized, some of which have showed encouraging clinical prospects but others have failed due to the complexity of pancreatic cancer...

DNA modifications such as 5-methylcytosine (5mC) and 5-hydroxymethylcytosine (5hmC) are epigenetic marks known to affect global gene expression in mammals. Given their prevalence in the human genome, close correlation with gene expression and high chemical stability, these DNA epigenetic marks could serve as ideal biomarkers for cancer diagnosis. Taking advantage of a highly sensitive and selective chemical labeling technology, we report here the genome-wide profiling of 5hmC in circulating cell-free DNA (cfDNA) and in genomic DNA (gDNA) of paired tumor and adjacent tissues collected from a cohort of 260 patients recently diagnosed with colorectal, gastric, pancreatic, liver or thyroid cancer and normal tissues from 90 healthy individuals...

Pancreatic ductal adenocarcinoma (PDAC) continues to have the poorest prognosis of all gastrointestinal malignancies, even after the tumor has been completely resected. However, only a proportion of patients achieve 5-year survival after resection. The factors predictive of achieving 5-year survival remain unclear. The aim of this study was to investigate the pre- and postoperative clinicopathological characteristics of PDAC patients with a >5-year survival after curative resection. We retrospectively reviewed patients who underwent pancreatectomy for PDAC between January 1995 and December 2011...

Irreversible electroporation (IRE) as a non-thermal tumor ablation technology has been studied for the treatment of pancreatic carcinoma and has shown a significant survival benefit. We discovered that moderate heating (MH) at 43 °C for 1-2 minutes significantly enhanced ex vivo IRE tumor ablation of Pan02 cells by 5.67-fold at 750 V/cm and by 1.67-fold at 1500 V/cm. This amount of heating alone did not cause cell death. An integrated IRE system with controllable laser heating and tumor impedance monitoring was developed to treat mouse ectopic pancreatic cancer...

Nab-paclitaxel, a nanoparticle conjugate of paclitaxel to human albumin, exhibits efficacy in pancreatic cancer, non-small cell lung cancer and breast cancer. However, there is a lack of predictive biomarkers to identify patients who might benefit most from its administration. This study addresses this gap in knowledge by identifying that caveolin-1 (Cav-1) is a candidate mechanism-based biomarker. Caveolae are small membrane invaginations important for trans-endothelial albumin uptake. Cav-1, the principal structural component of caveolae, is overexpressed in the cancers noted above which respond to nab-paclitaxel...

REVIEW
Neha Goel, Sanjay S Reddy
The management of pancreatic cancer has grown rapidly in the last decade. The Gastrointestinal Tumor Study Group trial in 1985 supported postoperative chemoradiation, and a more recent study recommended 6 months of adjuvant gemcitabine and capecitabine or monotherapy with gemcitabine or fluorouracil plus folinic acid, in the absence of neoadjuvant therapy. Clinicians are now studying the role of targeted therapy in pancreatic cancer and neoadjuvant chemotherapy in resectable, borderline resectable, and locally advanced pancreatic cancer...
