Journal ArticleDOI
Molecular Imaging of Proliferation and Glucose Utilization: Utility for Monitoring Response and Prognosis after Neoadjuvant Therapy in Locally Advanced Gastric Cancer
Katja Ott,Ken Herrmann,Tibor Schuster,Rupert Langer,Karen Becker,Hinrich Wieder,Hans-Jürgen Wester,J. R. Siewert,Christian Meyer zum Büschenfelde,Andreas K. Buck,Dirk Wilhelm,Matthias P. Ebert,Matthias P. Ebert,Christian Peschel,Markus Schwaiger,Florian Lordick,Bernd J. Krause +16 more
TL;DR: FLT uptake 2 weeks after initiation of therapy was shown to be the only imaging parameter with significant prognostic impact and neither FLT-PET nor FDG-PET were correlated with histopathological or clinical response.
Journal ArticleDOI
Modern imaging methods versus clinical assessment in the evaluation of hospital in-patients with suspected pancreatic disease.
Thomas Rösch,Volker Schusdziarra,Peter Born,Werner Bautz,Markus Baumgartner,Kurt Ulm,Reinhard Lorenz,Hans-Dieter Allescher,Paul Gerhardt,J. R. Siewert,Meinhard Classen +10 more
TL;DR: In a group of patients with a high suspicion of pancreatic disease, little additional sensitivity is provided by sophisticated imaging procedures such as EUS, ERCP, and CT, in comparison with clinical assessment including laboratory values and TUS, however, the specificity can be substantially improved.
Journal ArticleDOI
The 'angiogenic switch' in the progression from Barrett's metaplasia to esophageal adenocarcinoma.
C. Möbius,H. J. Stein,Ingrid Becker,Marcus Feith,J. Theisen,Peter Gais,U. Jütting,J. R. Siewert +7 more
TL;DR: The present study suggests, that an angiogenic switch might exist and that it is an early event in the metaplasia-dysPlasia-carcinoma sequence of Barrett's carcinoma, and that the neovascularisation phase in Barrett's cancer may precede tumour growth.
Journal ArticleDOI
Limited resection and free jejunal graft interposition for squamous cell carcinoma of the cervical oesophagus.
TL;DR: Outcome after limited resection and reconstruction with a free jejunal graft interposition was evaluated retrospectively.
Journal ArticleDOI
COX2 expression, angiogenesis, proliferation and survival in Barrett's cancer.
C. Möbius,H. J. Stein,C. Spieß,Ingrid Becker,Marcus Feith,J. Theisen,Peter Gais,U. Jütting,J. R. Siewert +8 more
TL;DR: Elevated COX2 expression is associated with lymph-node metastases and reduced survival in Barrett's cancer, and appears to be related to the induction of angiogenesis and proliferation.
