PURPOSE Contrary to the extensive data accumulated regarding pancreatic carcinogenesis, the clinical and molecular features characteristic of advanced stage (stage III and IV) disease are unknown. A comprehensive study of pancreatic cancers from patients who have succumbed to their disease has the potential to greatly expand our understanding of the most(More)
PURPOSE Positron emission tomography (PET) with [(18)F]fluorodeoxyglucose (FDG-PET) has increasingly been used to evaluate the efficacy of anticancer agents. We investigated the role of FDG-PET as a predictive marker for response to mammalian target of rapamycin (mTOR) inhibition in advanced solid tumor patients and in murine xenograft models. PATIENTS(More)
PURPOSE The purpose of this study was to analyze the value of germline and tumor thymidylate synthase (TS) genotyping as a prognostic marker in a series of colorectal cancer patients receiving adjuvant fluorouracil (FU) -based treatment. PATIENTS AND METHODS One hundred twenty-nine colorectal cancer patients homogeneously treated with FU plus levamisole(More)
Objective To assess the intraoperative positive sentinel lymph node (SLN) total tumor load (TTL, defined as the amount of CK19 mRNA copies [copies/μL] in all positive SLNs) obtained by one-step nucleic acid amplification (OSNA) and to determine whether it is predictive of non-SLNs involvement. Summary background data The OSNA assay (Sysmex Corporation,(More)
HMGCS2, the gene that regulates ketone body production, is expressed in liver and several extrahepatic tissues, such as the colon. In CaCo-2 colonic epithelial cells, the expression of this gene increases with cell differentiation. Accordingly, immunohistochemistry with specific antibodies shows that HMGCS2 is expressed mainly in differentiated cells of(More)
Analysis of sentinel lymph node (SLN) by means of One-Step Nucleic Acid Amplification (OSNA) is being used increasingly as a very sensitive and quick method for intraoperative axillary staging in patients with breast cancer. This molecular diagnostic assay detects the expression level of cytokeratin 19 (CK19), a luminal epithelial cell marker broadly(More)
PURPOSE The role of E-cadherin in carcinogenesis is of great interest, but few studies have examined its relevance to pancreatic carcinoma. EXPERIMENTAL DESIGN We evaluated E-cadherin protein expression by immunohistochemistry in pancreatobiliary cancers having a noncohesive histologic phenotype (21 undifferentiated adenocarcinomas and 7 signet ring(More)
The limitations of the current oncolytic adenoviruses for cancer therapy include insufficient potency and poor distribution of the virus throughout the tumor mass. To address these problems, we generated an oncolytic adenovirus expressing the hyperfusogenic form of the gibbon-ape leukemia virus (GALV) envelope glycoprotein under the control of the(More)
Recent studies have suggested that APC loss alone may be insufficient to promote aberrant Wnt/beta-catenin signalling. Our aim was to comprehensively characterize Wnt signalling components in a set of APC-associated familial adenomatous polyposis (FAP) tumours. Sixty adenomas from six FAP patients with known pathogenic APC mutations were included. Somatic(More)
We have previously shown that IKKs are aberrantly activated in colon cancer cells leading to SMRT phosphorylation and its release from the chromatin. We now show that IKKalpha phosphorylates the homologous N-CoR corepressor in serines 2345 and 2348 creating a functional 14-3-3 binding domain (RK(p)S(2348)KSP). Moreover, we have analyzed the subcellular(More)
