In conclusion, primary sarcomas of the larynx a re rare but tend to present with early symptoms. This likely allows for earlier detection and intervention as compared to their counterparts in other deep soft tissue locations. Pathologically, it is important, although difficult in some cases, to distinguish these neoplasms from sarcomatoid carcino ma and reactive processes. Careful morphologic and immunohistochemical evaluation, as well as correlation with the clinical and radiologic findings, is important for accurate tumor classification.

AbstractEwing sarcoma (ES) and Ewing-like sarcomas are highly aggressive round cell mesenchymal neoplasms, most often occurring in children and young adults. The identification of novel molecular alterations has greatly contributed to a profound reappraisal of classification, to the extent that the category of undifferentiated round cell sarcoma has significantly shrunk. In fact, in addition to Ewing sarcoma, we currently recognize three main categories: round cell sarcomas withEWSR1 gene fusion with non-ETS family members,CIC-rearranged sarcomas, andBCOR-rearranged sarcomas. Interestingly, despite significant morphologic ...

Authors: Lowery CD, Blosser W, Dowless M, Renschler M, Perez LV, Stephens J, Pytowski B, Wasserstrom H, Stancato LF, Falcon B Abstract Vascular endothelial growth factor receptor 2 (VEGFR2) is an attractive therapeutic target in solid malignancies due to its central role in tumor angiogenesis. Ramucirumab (Cyramza®, LY3009806) is a human monoclonal antibody specific for VEGFR2 approved for several adult indications and currently in a phase 1 clinical trial for pediatric patients with solid tumors (NCT02564198). Here, we evaluated ramucirumab in vitro and the anti-murine VEGFR2 antibody DC101 in vivo with or wit...

Publication date: Available online 2 July 2019Source: Pharmacology &TherapeuticsAuthor(s): Elizabeth Thoenen, Amanda Curl, Tomoo IwakumaAbstractGenomic and functional study of existing and emerging sarcoma targets, such as fusion proteins, chromosomal aberrations, reduced tumor suppressor activity, and oncogenic drivers, is broadening our understanding of sarcomagenesis. Among these mechanisms, the tumor suppressor p53 (TP53) plays significant roles in the suppression of bone and soft tissue sarcoma progression. Although mutations in TP53 were thought to be relatively low in sarcomas, modern techniques including whole-...

1295Introduction: Three-dimensional (3-D) displays for medical imaging is emerging field and very promising tools for diagnosis, therapy response and detection of tumor recurrence. Morphological criteria for therapy response (CR, PR, SD, PD) have been established with RECIST (Response evaluation criteria in solid tumors). With adoption of metabolic imaging with PET/CT, particularly with F-18-FDG in initial staging and follow up of tumors, there appears to be a need to modify these criteria not only on morphological imaging modalities like CT, but also on tumor metabolism parameters, like SUV (standardized uptake value) as ...

Authors: Hatina J, Kripnerova M, Houfkova K, Pesta M, Kuncova J, Sana J, Slaby O, Rodríguez R Abstract Sarcomas represent an extensive group of divergent malignant diseases, with the only common characteristic of being derived from mesenchymal cells. As such, sarcomas are by definition very heterogeneous, and this heterogeneity does not manifest only upon intertumoral comparison on a bulk tumor level but can be extended to intratumoral level. Whereas part of this intratumoral heterogeneity could be understood in terms of clonal genetic evolution, an essential part includes a hierarchical relationship between...

Conclusion: Fat fraction on MRI corresponded to fat content on histology and therefore contributes to lesion characterization. Measurement repeatability was excellent for ADC; this parameter increased significantly post-radiotherapy even in disease categorized as stable by size criteria, and corresponded to cellularity on histology. ADC can be utilized for characterizing and assessing response in heterogeneous retroperitoneal sarcomas. Introduction Soft-tissue sarcomas are often highly heterogeneous tumors with variable components that can include cellular tumor, fat, necrosis, and cystic change. In many soft-tissue ...

CONCLUSION: Musculoskeletal tumors are rare, but descriptive data in any region are important in order to reduce mortality and improve treatment. No significant difference was found between the data of our hospital regarding epidemiology of the musculoskeletal system tumors and those from the other regions around the world. LEVEL OF EVIDENCE: Level IV, Therapeutic study. PMID: 30982757 [PubMed - as supplied by publisher]

CONCLUSION: Surgical treatment of primary malignant tumors of the proximal fibula is problematic. In appropriate indications, Malawer type 1 resection should be the treatment of choice due to lower local recurrence rates and higher MSTS scores. PMID: 30885105 [PubMed - in process]
