BACKGROUND The value of second-line therapy for metastatic gastric cancer is unclear. So far there are no randomised phase III data comparing second-line chemotherapy to best supportive care (BSC). In this prospective, multicenter, open label, randomised phase III study we compared irinotecan to BSC to evaluate the impact on survival of second-line(More)
Soft tissue sarcomas are characterized by their heterogeneity. With new diagnostic imaging techniques, low- and high-grade components of the tumor can be differentiated. Thus biopsies should be guided by imaging to assure representative specimens. Besides histopathology, the advent of chromosomal and gene expression analysis may allow more accurate(More)
PURPOSE Evaluation of 3D multislice CT angiography for the assessment of relevant stenoses of pelvic arteries and arteries of the lower extremity in patients with peripheral artery occlusive disease compared to digital subtraction angiography. METHOD/MATERIALS For this study we examined 31 patients with peripheral artery occlusive disease. All patients(More)
PURPOSE Prospective analysis of success and complication rates of chest port implantation via the internal jugular vein. MATERIALS AND METHODS In 50 consecutive patients (25 men, 25 women; mean age 61 +/- 14 years) the internal jugular vein was punctured under ultrasound guidance. Through this access, a port system was inserted and the catheter tip was(More)
In this retrospective study the success and complication rates after radiologically guided port catheter implantation were evaluated. Between 2000 and 2008, 3,160 port catheter systems were implanted in our interventional suite. All interventions were imaging guided. The puncture of the preferably right internal jugular vein (IJV) was ultrasound-assisted(More)
Evaluate the clinical outcome of CT-guided high-dose-rate-brachytherapy (CT-HDRBT) of hepatocellular carcinoma (HCC) larger than 5 cm in diameter with the goal of local tumour control (LTC). Thirty-five patients with 35 unresectable HCCs ranging in size from 5 to 12 cm (mean: 7.1 cm) were treated with CT-HDRBT. Tumours were classified into two groups(More)
The purpose of this study was to analyze the clinical outcome of osteoid osteoma treated by thermal ablation after drill opening. A total of 17 patients and 20 procedures were included. All patients had typical clinical features (age, pain) and a typical radiograph showing a nidus. In 5 cases, additional histological specimens were acquired. After drill(More)
Computed tomography is the standard imaging modality to minimize the extent of surgical or ablative treatment in osteoid osteomas. In the last 15 years, since a description of thermal ablation of osteoid osteomas was first published, this technique has become a treatment of choice for this tumor. We report the case of a 20-year-old man with an osteoid(More)
4540 Background: Up to now the value of 2nd-line therapy for metastatic gastric cancer is unclear. So far there are no randomized phase III data comparing 2nd-line chemotherapy to BSC. Irinotecan has proven activity in 1st-line therapy. In this randomized phase III study we compared irinotecan to BSC to evaluate the value of 2nd- line chemotherapy for(More)
PURPOSE To evaluate the feasibility and complications of percutaneous push-through gastrostomy via a computed tomography (CT)--guided gastropexy. MATERIALS AND METHODS From January 2005 to March 2008, 14 patients in whom an oropharyngeal passage with an endoscope was impossible received a gastrostomy using the push-through technique. To attach the stomach(More)
