(Submitter supplied) Pancreatic ductal adenocarcinoma (PDAC) is a heterogeneous cancer in which differences in survival rates might be related to a variety in gene expression profiles. Although the molecular biology of PDAC begins to be revealed, genes or pathways that specifically drive tumour progression or metastasis are not well understood. Therefore, we performed microarray analyses on whole-tumour samples of 2 human PDAC subpopulations with similar clinicopathological features, but extremely distinct survival rates after potentially curative surgery, i.e., good outcome (OS and DFS > 50 months) versus bad outcome (OS < 19 months and DFS < 7 months). more...

(Submitter supplied) Most cancer deaths are caused by metastases, which are the end-results of circulating tumor cells (CTC) that detach from the cancer primary and succeed to survive in distant organs. The aim of the present study was to develop a gene signature of CTC and to assess its prognostic relevance after surgery for pancreatic ductaladenocarcinoma (PDAC). A negative depletion fluorescence activated cell sorting (FACS) procedure was developed and validated with spiking experiments using cancer cell lines in whole human blood samples. more...

Analysis of circulating tumor cells (CTC) from patients who underwent surgery for PDAC. Most cancer deaths are caused by metastases, resulting from CTCs that detach from the primary cancer and survive in distant organs. Results provide insight into molecular characterization of CTC motility in PDAC.
