[Consensus recommendations on regional interdisciplinary standardization of MRI diagnostics for multiple sclerosis in the metropolitan area of Essen]. / Konsensusempfehlungen zur regionalen fächerübergreifenden Standardisierung der MRT-Diagnostik bei Multipler Sklerose im Großraum Essen.

Magnetic resonance imaging (MRI) is of exceptional importance in the diagnostics and monitoring of multiple sclerosis (MS); however, a close interdisciplinary cooperation between neurologists in private practice, (neuro)radiological practices, hospitals or specialized MS centers is only rarely established. In particular, there is a lack of standardized MRI protocols for image acquisition as well as established quality parameters, which guarantee the comparability of MRI records; however, this is a fundamental prerequisite for an effective application of MRI in the treatment of MS patients, e.g., for making the diagnosis or treatment monitoring. To address these challenges a group of neurologists and (neuro)radiologists developed a consensus proposal for standardization of image acquisition, interpretation and transmission of results and for improvement in interdisciplinary cooperation. This pilot project in the metropolitan area of Essen used a modified Delphi process and was based on the most up to date scientific knowledge. The recommendation takes the medical, economic, temporal and practical aspects of MRI in MS into consideration. The model of interdisciplinary cooperation between radiologists and neurologists with the aim of a regional standardization of MRI could serve as an example for other regions of Germany in order to optimize MRI for MS.

Hepatic arterial infusion chemotherapy for extensive liver metastases of breast cancer: efficacy, safety and prognostic parameters.

PURPOSE: Hepatic arterial infusion chemotherapy (HAIC) is an option for patients with liver-predominant metastatic breast cancer (LMBC), when no further systemic treatment is available. But systematic reports are limited. Here we conducted a retrospective analysis of LMBC patients treated at an expert center. METHODS: Individual patient data were retrieved from the clinical data base of the West German Cancer Center. Primary endpoints included hepatic response (RECIST), progression-free survival (PFS), overall survival (OS), and toxicity. A score based on LDH, AST, ALT and bilirubine was developed to estimate the hepatic metastasis load. RESULTS: Data from 70 consecutive patients were included. All patients were heavily pretreated (median 7 treatment lines for LMBC). HAIC protocols included mitomycin/5-FU (70%), mitomycin (14.3%), melphalan (12.9%) and 5-FU (7.1%), with selection based on patient characteristics. Partial hepatic remission was obtained as best response in 14 patients (20.0%), stable disease in 27 patients (38.6%), and progressive disease in 29 patients (41.4%). Median PFS and OS from initiation of HAIC were 2 (range 0-10) and 7 months (range 1-37). Mainly hepatic and hematopoietic HAIC-related toxicities were observed; there was no treatment-related death. The hepatic metastasis score effectively separated two prognostic groups: Patients with a score <3 had significantly superior PFS (15 vs 7 weeks, p = 0.017) and OS (12 vs 5 months, p = 0.002). CONCLUSION: HAIC offers a safe and effective salvage treatment strategy in heavily pretreated patients with LMBC and no further treatment options. The hepatic metastasis score may help to identify patients with sustained clinical benefit.
