Comparative genomic hybridisation (CGH) was performed on tumors to identify changes that may predict response to treatment. Results: Fourteen patients were treated, mean treatment time 22.3 months (1 nonresponse, 2 progression after initial response, 2 stable diseases, 8 partial responses, 1 complete response). Adverse side effects were mild in general. Survival was higher in the treated group (41.1 months vs. 34.8 months in the historical group). Eleven treated patients are alive.

The aim of the study was to investigate quality of life and outcome of ultrasound-guided laser interstitial thermotherapy (US-LITT) in patients with liver metastases of colorectal cancer. Methods In this prospective non-randomized study, 45 patients with liver metastases of colorectal cancer were palliatively treated by US-LITT. Patient survival was analysed by the Kaplan-Meier method and the quality of life by questionnaire C30 of the European Organisation for Research and Treatment of Cancer before, and 1 week, 1 month, and 6 months after initiation of US-LITT. Results Median survival after initiation of US-LITT was 8.5 +/- 0.7 months with a range of 1.5-18 months. Body weight was constant 1 month after US-LITT. In the multivariate analyses, quality-of-life symptoms and functioning scales did not deteriorate in patients alive at 6 months after initiation of US-LITT. Univariate analyses outlined a significant increase of the pain subscale before and at 1 week after US-LITT.

The oncogenic potential of this polyomavirus was revealed when intracerebral inoculation of SV40 into newborn hamsters resulted in the development of ependymomas and choroid plexus papillomas. Subsequently, SV40-like sequences were repeatedly detected in human ependymomas with broadly ranging incidence rates of 7-90%. Most epidemiological studies, however, have not described an increased occurrence of ependymomas. To gain more data on this controversial issue, this study examined 62 archived ependymal tumours from 31 children and 31 adults who underwent surgery between 1990 and 1999. Only three (5%) of the tumours - including 24 classical, 20 anaplastic, and 12 myxopapillary ependymomas; one subependymoma; and five ependymoblastomas - revealed subgenomic SV40 sequences. None of the ependymomas in patients born between 1920 and 1960 demonstrated SV40-like sequences. The positive tumours represent 7% of grade II and III ependymomas (two paediatric and one adult tumour). DNA sequencing of the PCR product revealed identical sequences of SV40 in the positive ependymal tumours. Compared with the results from other countries, this incidence rate is relatively low. Therefore, it seems likely that significant differences between individual countries exist regarding the prevalence of SV40-positive ependymomas. These differences may reflect different degrees of exposure to SV40-contaminated polio vaccine.

The aim of the present study was to determine the concentrations of ET-1 in the systemic and splanchnic circulation before and after reduction of portal hypertension by transjugular intrahepatic portosystemic shunt implantation (TIPS). Methods: Plasma concentrations of immunoreactive ET-1 were measured in peripheral venous blood samples from 25 patients with liver cirrhosis before and at 1, 3, 9 and 15 months after TIPS. Furthermore, acute effects of TIPS on ET-1 were studied in plasma samples from the hepatic vein, the portal vein 30 minutes before and after TIPS and in the femoral artery (only after TIPS) in a subgroup of 15 patients. In addition, the portocaval pressure gradient was determined before and after TIPS. Results: Before TIPS peripheral venous plasma ET-1 concentrations (n=25; median 4.2 pg/ml; range 1.9–14.7) were significantly increased in patients with refractory ascites (n=7; median 7.8, range 3.5–14.7) compared to patients with repetitive bleeding (n=18; median 3.4; range 1.9–7.1) (p=0.003). Furthermore, peripheral ET-1 concentrations correlated with the degree of liver dysfunction according to the Child-Pugh classification (Spearman's r=0.46; p=0.02). Following TIPS, peripheral ET-1 concentrations remained unchanged during a follow-up of 15 months. Before TIPS, a positive gradient of ET-1 concentrations from portalvenous to hepatovenous and peripheral venous levels was found (p<0.03). Immediately after TIPS, arterial ET-1 concentrations reached markedly increased levels in individual patients (88, 92 and 103 pg/ml). Severe systemic reactions to these high levels were not observed. Peripheral venous, hepatovenous and portalvenous ET-1 concentrations did not correlate with portocaval pressure gradients. Conclusion: Cirrhotic patients demonstrated unchanged peripheral venous ET-1 concentrations up to 15 months after TIPS. Portal congestion was associated with increased ET-1 levels in the prehepatic splanchnic area. The effect of portal decompression on splanchnic and systemic ET-1 levels deserves further investigation."],["dc.identifier.doi","10.1034/j.1600-0676.2000.020001060.x"],["dc.identifier.gro","3151647"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/8464"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.notes.submitter","chake"],["dc.relation.issn","1478-3223"],["dc.title","Systemic and splanchnic endothelin-1 plasma levels in liver cirrhosis before and after transjugular intrahepatic portosystemic shunt (TIPS)"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]

In general, tumour site correlated with key prognostic factors, including tumour size, mitotic rate, proliferative activity, and probable malignant potential. Furthermore, several DNA copy number changes showed a site-dependent pattern.
