Die selektive interne Radiotherapie (SIRT) im multimodalen Behandlungskonzept beim hepatozellulären Karzinom : klinische…

Patienten mit einem hepatozellulären Karzinom (HCC) haben in vielen Fällen eine schlechte Prognose, da kurative Therapien im fortgeschrittenen Stadium oft nicht mehr in Betracht kommen. Die selektive interne Radiotherapie (SIRT) ist als palliativer Therapieansatz verträglich und als Bridging-Therapie…

Automatische Konturierungsansätze in der Planung der Bestrahlung des linksseitigen Mammakarzinoms : atlasbasierte Konturierung…

Hintergrund: Bei der Therapie des Mammakarzinoms stellt die Radiotherapie eine wichtige Säule dar. Da die manuelle Konturierung von Zielvolumina und Risikoorganen in der Bestrahlungsplanung sehr zeitaufwendig ist, kommen automatische Verfahren zum Einsatz. Eine Möglichkeit bietet atlasbasierte automatische…

Angiographic Aspects of Transarterial Radioembolization : A Comparison of Technical Options to Avoid Extrahepatic Microsphere…

The influence of the interventional treatment approach for transarterial radioembolization (TARE) on the incidence of extrahepatic microsphere depositions and to angiographic complications was evaluated. In total, 398 TARE cycles were analyzed. Interventional treatment approaches were classified as single…

Die 18F-FDG-PET/CT in der präoperativen Diagnostik des Lungenkarzinoms und als Prädiktor einer N+-Situation

In der vorliegenden Arbeit wurden präoperative 18F-FDG-PET/CT-Befunde von 104 Lungenkarzinompatienten, die innerhalb von zwei Jahren am Universitätsklinikum Jena operiert wurden, mit dem postoperativen histopathologischen Befund verglichen. Ziel war die Bestimmung der Genauigkeit der PET/CT bei der Erkennung…

Transarterial Radioembolization (TARE) in Patients with Hepatocellular Carcinoma : A Comparison of Palliative with Bridging-to-Transplant…

aus: Cancers
We investigated transarterial radioembolization (TARE) as a palliative measure and bridging-to-transplant therapy in hepatocellular carcinoma (HCC) patients. A total of 167 patients (50 bridging, 117 palliative) with 245 TARE procedures were assessed. Fourteen patients underwent subsequent liver transplantation…
