Imaging of Orthotopic Glioblastoma Xenografts in Mice Using a Clinical CT Scanner: Comparison with Micro-CT and Histology

2016

Purpose There is an increasing need for small animal in vivo imaging in murine orthotopic glioma models. Because dedicated small animal scanners are not available ubiquitously, the applicability of a clinical CT scanner for visualization and measurement of intracerebrally growing glioma xenografts in living mice was validated. Materials and Methods 2.5x106 U87MG cells were orthotopically implanted in NOD/SCID/ᵞc-/- mice (n = 9). Mice underwent contrast-enhanced (300 μl Iomeprol i.v.) imaging using a micro-CT (80 kV, 75 μAs, 360° rotation, 1,000 projections, scan time 33 s, resolution 40 x 40 x 53 μm) and a clinical CT scanner (4-row multislice detector; 120 kV, 150 mAs, slice thickness 0.5 …

Oxaliplatin and Capecitabine-Based Chemoradiotherapy for Gastric Cancer—An Extended Phase I MARGIT and AIO Trial

2008

Purpose Adjuvant 5-fluorouracil–based chemoradiotherapy has been shown to improve the prognosis of gastric cancer. To optimize these results, in the present study oxaliplatin and capecitabine were used instead of 5-fluorouracil. We sought to determine the maximum tolerated dose and the dose-limiting toxicities (DLT) of these drugs in combination with intensity-modulated radiotherapy. Methods and Materials Patients with resected adenocarcinoma of the stomach or the gastroesophageal junction were included. They received two cycles of induction chemotherapy (oxaliplatin and capecitabine [XelOx] regimen). Using standard Phase I methodology, patients received 45 Gy in 1.8-Gy fractions either in …

Irradiation Delays Tissue Growth but Enhances Osteogenic Differentiation in Vascularized Constructs.

2018

Background Regenerative medicine is still deficient in the reconstruction after cancer due to impaired vascularization after radiotherapy and due to the need to substitute larger defects after tumor excision. Aiming at introducing regenerative medicine for reconstruction after cancer, we tested an axially vascularized bone construct in an experimental setting that mimics the clinical situation after tumor resection and adjuvant radiotherapy. Methods Twenty bone constructs were axially vascularized using microsurgically created arteriovenous loops and were implanted subcutaneously in Lewis rats. After 2 weeks, the animals were randomly allocated either to receive a clinically relevant singl…

Association Between Tumor Egfr and Kras Mutation Status and Clinical Outcomes in Nsclc Patients Randomized to Sorafenib Plus Best Supportive Care (BS…

2012

ABSTRACT Background Tumor EGFR and KRas mutations are both predictive and prognostic biomarkers in patients with advanced NSCLC. We analyzed the correlation between these biomarkers and treatment outcomes in a phase III trial of 3rd/4th line sorafenib in patients with NSCLC. Methods The global, randomized, placebo-controlled MISSION trial enrolled 703 patients with advanced relapsed/refractory NSCLC of predominantly non-squamous histology. The primary study endpoint was overall survival (OS). EGFR and KRas mutations were analyzed in archival tumor samples and in circulating tumor DNA isolated from plasma. Results Tumor and/or plasma mutation data were available from 347 patients (49%). EGFR…
