ZusammenfassungDie Versorgung von unfallbedingten Notfällen in der Schwangerschaft gehört selbst in überregionalen Traumazentren nicht zur täglichen Routine. Wir präsentieren den Fall einer 27 Jahre alten, nicht vorerkrankten Polytraumapatientin in der 30. Schwangerschaftswoche. Die führende Verletzung war eine Beckenfraktur mit spinopelviner Dissoziation und kreislaufrelevanter, intrapelviner Blutung. Durch ein konsequentes Polytraumamanagement, notfallmäßige Sectio, Ligatur der Corona mortis, Packing und operative Frakturstabilisierung des Beckens konnte das Leben der Mutter und des Kindes gerettet werden.

e23540 Background: Early presentation of soft-tissue sarcoma (STS) patients to a specialized sarcoma center including discussion in the interdisciplinary sarcoma board (ISB) prior to surgery is essential to the treatment of sarcomas. This approach significantly improves patient survival and guideline coherence. However, there exists only limited information on the adherence to the recommendations of the ISB. Accordingly, we decided to analyze a STS cohort at a large German sarcoma center focusing on outcome parameters and adherence to quality parameters defined by the German Cancer Society (Deutsche Krebsgesellschaft). Methods: In a retrospective data analysis, we identified n = 230 adult patients presented at the ISB of the Charité–Universitätsmedizin Berlin in Germany from January 2015 until December 2019. Inclusion criteria were as follows: newly diagnosed STS, presentation during first-line therapy and recommendation of at least one treatment modality such as surgery, chemotherapy, radiotherapy, regional hyperthermia or follow-up by the ISB. Clinical and follow up data was collected by using the hospital information system and the outpatient network. Results: Our patient cohort included 53% male and 47% female patients with a median age of 58 years (range 19-96). The majority (86%) showed a localized tumor stage, while 14% already had metastases. In 24% of the cases the sarcomas were classified as low-grade, in 76% as high-grade. Surgery was recommended for 66% of the cases, for 80% of them combined with chemotherapy, radiotherapy or hyperthermia. 14% of the patients received a recommendation for all 4 modalities. For 9% of the patients, chemotherapy alone was recommended. Both overall survival and progression-free survival was significantly higher in the group with complete adherence to the recommendations of the ISB (p < 0.001). The worst prognosis was found in patients unable to adhere to the recommendations due to rapid progression or complications of the therapy (HR for death 15.06, 95%CI 7.94-32.22). If one recommended modality was not carried out, there also was a higher risk of death (HR 4.38, 95%CI 1.75-10.96). Most common reasons were patient refusal or individual decision by the treating physician. A metastasized tumor stage was associated with an increased risk of death (HR 2.62, 95%CI 1.45-4.75). In contrast, neither the histological grading (low vs. high) nor age did influence the mortality significantly. Conclusions: In our cohort of STS patients, survival depends significantly on adherence to the recommendations of the ISB. Our analysis at a German sarcoma center is in line with previous international reports demonstrating the importance of interdisciplinary decisions and therapeutic adherence. We hereby underline the essential role of interdisciplinary approaches in care of STS patients and the effort to implement defined quality parameters.

Background High-energy trauma patients represent the ultimate challenge to trauma care and are at risk of injury-related mortality and morbidity-a common cause of loss of productivity. The aim of this study was to implement computed tomography (CT)-derived, artificial intelligence (AI)-based body composition analysis (BCA) to identify predictors of morbidity. Methods Retrospectively, we enrolled 104 patients (38 females and 66 males) who underwent CT imaging for assessment of injuries caused by high-energy trauma (motor vehicle accidents, falls from significant height, or blast injury). We sought to identify risk factors for prolonged length of stay in hospital and intensive care unit (ICU) and fractures requiring pelvic surgery. Cox and logistic regression analysis were performed using BCA parameters as covariates besides conventional risk factors. Additionally, the effects of pre-existing conditions, obesity, and sarcopenia were analysed. Results Increased subcutaneous adipose tissue (SAT), determined by BCA, at hospital admittance is a predictor of prolonged hospital stay (P = 0.02) independent of treatment regime and occurrence of related complications, whereas muscle mass does not influence the length of stay. Individuals with sarcopenia and a decreased psoas muscle index (PMI) sustaining high-energy trauma are at risk of pelvic injuries requiring surgical treatment. Conclusion BCA parameters are easily available from routine CT and significantly predict outcomes in trauma patients with pelvic injuries. Patients with reduced muscle mass are at risk for injuries requiring pelvic surgery, and increased SAT is a risk factor for longer hospital stays. These findings underline the potential of BCA, which may be valuable in identifying trauma patients who require specific support to optimize their physiological reserves and clinical outcome.
