Abstract
BACKGROUND Cancer research has made great progress in the recent years. With the increasing number of options in diagnosis and therapy the implementation of tumorboards (TUBs) has become standard procedure in the treatment of cancer patients. Adherence tests on tumor board decisions are intended to enable quality assurance and enhancement for work in tumor boards in order to continuously optimize treatment options for cancer patients. METHODS Subject of this study was the adherence of the recommendations made in three of 14 tumorboards, which take place weekly in the Center for Integrated Oncology (CIO) at the University Hospital Bonn. In total, therapy recommendations of 3815 patient cases were checked on their implementation. A classification into four groups has been made according to the degree of implementation. A second classification followed regarding the reasons for differences between the recommendation and the therapy which the patient actually received. RESULTS The study showed that 80.1% of all recommendations in the three TUBs were implemented. 8.3% of all recommendations showed a deviance. Most important reasons for the deviances were patient wish (36.5%), patient death (26%) and doctoral decision, due to the patient's comorbidities or side effects of the treatment (24.1%).Interestingly, deviance in all three tumor boards in total significantly decreased over time. CONCLUSIONS Aim of the study was to clarify the use of tumor boards and find approaches to make them more efficient. Based on the results efficiency might be optimized by increased consideration of patients` preferences, improved presentation of patient-related data, more detailed documentation and further structuring of the tumor board meetings.

Abstract
To improve the quality of healthcare, we offer access to high quality guidelines to physicians as well as information harmonized with these guidelines to concerned patients via internet. We launched this service in 1994. Since then, we have been offering user-friendly access to the NCI's CancerNet via WWW (http://www.meb.uni-bonn.de/). Among other information, CancerNet by the National Cancer Institute contains up-to-date summaries on the prognosis, staging, and treatment of more than 80 major tumor types. To obtain information about how users navigate through this service, all users' activities are logged by using cookies for tracking them without injuring privacy. To get additional information about our users and their interests regarding our service, we performed user surveys in 1996 and 1997. The analysis of 538 valid answers in 1996 and 1001 in 1997 show that the attempt to bring high quality information and guidelines to physicians and patients was successful. About 95% of our users rated our service "excellent" or "good".

Abstract
PURPOSE To evaluate the differentiation of benign from malignant breast tumors with T2*-weighted perfusion magnetic resonance (MR) imaging (blood volume imaging) versus that with dynamic T1-weighted contrast agent-enhanced MR imaging. MATERIALS AND METHODS Ten healthy adult volunteers and 18 adult patients with benign or malignant lesions underwent both conventional T1-weighted dynamic contrast-enhanced breast MR imaging and repetitive first-pass, single-section, dynamic T2*-weighted perfusion MR imaging. Images were obtained before, during, and after injection of 20 mL of gadopentetate dimeglumine; peak gadopentetate dimeglumine concentrations were calculated from the maximal signal intensity loss on T2*-weighted images. RESULTS No perfusion effect was detectable in healthy breast parenchyma. A strong susceptibility-mediated signal intensity loss occurred in malignant breast tumors. No or only minor perfusion effects were seen in fibroadenomas, in spite of their rapid enhancement at T1-weighted dynamic imaging. Perfusion imaging was possible after conventional dynamic contrast-enhanced breast MR imaging. CONCLUSION T2*-weighted perfusion imaging exploits the susceptibility-mediated signal intensity loss of a first-pass bolus of gadopentetate dimeglumine within the capillary bed. First-pass perfusion imaging of breast lesions is feasible. It is promising in the differentiation of benign from malignant, rapidly enhancing lesions.

Abstract
CancerNet from the National Cancer Institute contains nearly 500 ASCII-files, updated monthly, with up-to-date information about cancer and the "Golden Standard" in tumor therapy. Perl scripts are used to convert these files to HTML-documents. A complex algorithm, using regular expression matching and extensive exception handling, detects headlines, listings and other constructs of the original ASCII-text and converts them into their HTML-counterparts. A table of contents is also created during the process. The resulting files are indexed for full-text search via WAIS. Building the complete CancerNet WWW redistribution takes less than two hours with a minimum of manual work. For 26,000 requests of information from our service per month the average costs for the worldwide delivery of one document is about 19 cents.
