PET/MRI Imaging in High-Risk Sarcoma: First Findings and Solving Clinical Problems

Simultaneous positron emission tomography (PET) and magnetic resonance imaging (MRI) is a new whole-body hybrid PET/MR imaging technique that combines metabolic and cross-sectional diagnostic imaging. Since the use of MRI in imaging of soft-tissue sarcoma is extremely beneficial, investigation of the combined PET/MRI is of great interest. In this paper, we present three cases and first data. Combined PET/MRI technique can support the process of clinical decision-making and give answers to some meaningful questions when treating patients with STS. Therefore, the combined modality of simultaneous PET/MRI offers new pieces to the puzzle of sarcoma treatment.

Trabectedin in the Neoadjuvant Treatment of High-Grade Pleomorphic Sarcoma: Report of a Rare Case and Literature Review

Background. Pleomorphic sarcoma is an aggressive soft tissue sarcoma. In patients with high-risk extremity sarcomas, the significant survival benefits conferred by an intense regimen of neoadjuvant chemoradiotherapy and surgery were reported. To our knowledge, this is the first report in the literature of the neoadjuvant use of trabectedin in a patient with high-grade pleomorphic sarcoma, ineligible for standard neoadjuvant combination therapy with an anthracycline-based regimen. Case Presentation. Here we present a 58-year-old White male with a large tumor in the left thigh, but with no signs of metastases. Owing to the history of severe heart attack, three cycles of neoadjuvant trabectedin were administrated to achieve surgically wide margins. After two cycles, an 18F-FDG-PET showed a large proportion of the central tumor area was without metabolic activity. According to RECIST and Choi criteria, the tumor was stable. After the third cycle of trabectedin, the patient underwent a complete resection, which revealed completely necrotic high-grade pleomorphic sarcoma (stage pT2b), with only a small vital area. Conclusion. The present paper on a promising treatment with neoadjuvant trabectedin of patients with high-grade pleomorphic sarcoma might suggest that such treatment approach may provide a greater chance of cure and survival of such patients.

A cluster-randomised, controlled proof-of-concept study to explore the feasibility and effect of a patient-directed intervention on quality of life in patients with advanced soft tissue sarcoma

Introduction Even with evolving and expanding therapeutical options for the treatment of advanced sarcomas over recent years, the balance between efficacy and toxicity still remains a major concern. Moreover, the symptom burden in patients with sarcoma remains high compared with other malignant diseases. It is, therefore, crucial to assess treatment effectiveness not only in terms of disease-related outcomes (eg, overall survival) but also from an individual and patient-centred perspective using the assessment of patient-reported outcomes (PROs). By focusing on PROs as a primary study endpoint, we aim to address key issues for patients with advanced soft tissue sarcoma (STS) undergoing palliative treatment. Methods and analysis The protocol of the YonLife study describes a multicentre, cluster-randomised, controlled, open-label proof-of-concept study conducted in patients with advanced or metastatic STS treated with trabectedin in seven German hospitals. The primary objective of the study is to exploratively compare overall quality of life between the patients receiving a multidimensional intervention based on individual PROs and those receiving usual supportive treatment. This complex intervention consists of the (1) electronic assessment of PRO, (2) creation of a case vignette based on PRO and clinical data and (3) treatment suggestions based on the discussion of these vignettes in a regularly meeting expert panel. Additionally, the YonLife trial assesses the applicability of a tablet-based assessment of PROs. Patients’ and physicians’ acceptance and challenges concerning the implementation process will be evaluated. Ethics and dissemination The YonLife trial has been approved by the Ethics Committee of the University Hospital Dresden as well as by the relevant institutions of each participating centre before patient enrolment. The findings will be reported via relevant peer-reviewed journals as well as through presentation at international conferences. Trial registration number NCT02204111, pre-results.

Bone marrow metastases by alveolar rhabdomyosarcoma in a 31-year-old patient

![Figure][1] In March 2012, a 31-year-old male patient was diagnosed with alveolar rhabdomyosarcoma (ARMS) manifesting within the left sinus maxillaris with local lymphonodular metastases. No further metastases could be found by positron emission tomography–magnetic resonance imaging. He
