Journal ArticleDOI
Prognostic value of indoleamine 2,3-dioxygenase expression in colorectal cancer: effect on tumor-infiltrating T cells.
Gerald Brandacher,Alexander Perathoner,Ruth Ladurner,Ruth Ladurner,Stefan Schneeberger,Peter Obrist,Christiana Winkler,Ernst R. Werner,Gabriele Werner-Felmayer,Helmut Weiss,Georg Göbel,Raimund Margreiter,Alfred Königsrainer,Alfred Königsrainer,Dietmar Fuchs,Albert Amberger +15 more
TL;DR: IDO-high expression by colorectal tumor cells enables certain cancer subsets to initially avoid immune attack and defeat the invasion of T cells via local tryptophan depletion and the production of proapoptotic tryPTophan catabolites.
Journal ArticleDOI
Expression of the duodenal iron transporters divalent-metal transporter 1 and ferroportin 1 in iron deficiency and iron overload
Heinz Zoller,Robert Koch,Igor Theurl,Peter Obrist,Antonello Pietrangelo,Giuliana Montosi,David J. Haile,Wolfgang Vogel,Günter Weiss +8 more
TL;DR: DMT1 and FP1 are centrally involved in iron uptake/transfer in the duodenum and in the adaptive changes of iron homeostasis to iron deficiency and overload.
Journal ArticleDOI
Ep-CAM overexpression in breast cancer as a predictor of survival.
TL;DR: The frequency and prognostic significance of Ep-CAM in tissue specimens from 205 patients with invasive breast cancer were assessed by immunohistochemical staining with a monoclonal antibody specific for the Ep- CAM antigen.
Journal ArticleDOI
Clinically and mammographically occult breast lesions: Detection and classification with high-resolution sonography
TL;DR: The use of high-resolution sonography as an adjunct to mammography in women with dense breasts may lead to detection of a significant number of otherwise occult cancers that are no different in size from nonpalpable mammographically detected cancers.
Journal ArticleDOI
High Ep-CAM expression is associated with poor prognosis in node-positive breast cancer.
Gilbert Spizzo,G. Gastl,Peter Obrist,Philip Went,Stephan Dirnhofer,Susanne Bischoff,Martina Mirlacher,Guido Sauter,Ronald Simon,Shanna Stopatschinskaya,Philip Haas,Rahel Bart,O.R. Köchli,Hanspeter Spichtin,Robert Maurer,U. Metzger,Brida von Castelberg,Markus Zuber,Friedrich Mross,Holger Dietrich +19 more
TL;DR: There is strong evidence that expression of Ep-CAM is a powerful marker of poor prognosis in node-positive invasive breast carcinoma and a potential predictive marker of sensitivity to adjuvant hormonal and/or cytotoxic treatment modalities.
