BACKGROUND: Malignant fibrous histiocytoma is a sarcoma of uncertain origin that can be found both in soft tissues and in bones. It is currently called undifferentiated pleomorphic sarcoma not otherwise specified and it represents a final common pathway in several tumors that are subject to the progress of dedifferentiation. Local recurrence of the tumor in the same location where it was originated occurs in 20-30% of the total number of soft tissue sarcomas. It is less frequent in limbs and more likely to recur in retroperitoneal sarcomas and in head and neck...

Ewing sarcomas (ES) are biologically aggressive tumors of bone and soft tissues for which no cure is currently available. Most ES patients do not respond to chemotherapeutic treatments or acquire resistance. Since the PI3K/AKT/mTOR axis is often deregulated in ES, its inhibition offers therapeutic perspective for these aggressive tumors. Herein, by using splicing sensitive arrays, we have uncovered an extensive splicing program activated upon inhibition of the PI3K/AKT/mTOR signaling pathway by BEZ235. Bioinformatics analyses identified hnRNPM as a key factor in this response...

Adamantinoma-like Ewing sarcoma (AES) is a rare variant of Ewing sarcoma family of tumors (EFTs), primarily affecting bone and soft tissue. AES has mixed features of Ewing sarcoma (ES)/primitive neuroectodermal tumor (PNET) and adamantinoma with a complex immunoprofile and EWSR1 gene rearrangements. Herein, we report a 72-year-old male who presented with left parotid mass, right neck mass and thyroid nodules. Fine needle aspiration of the left parotid mass displayed nests of monotonous epithelioid cells with basaloid features in a background of small round blue cells and lymphocytes...

Despite advances in conventional chemotherapy, surgical techniques, and radiation, outcomes for patients with relapsed, refractory, or metastatic soft tissue sarcomas are dismal. Survivors often suffer from lasting morbidity from current treatments. New targeted therapies with less toxicity, such as those that harness the immune system, and immunocompetent murine sarcoma models to test these therapies are greatly needed. We characterized two new serendipitous murine models of undifferentiated sarcoma (SARC-28 and SARC-45) and tested their sensitivity to virotherapy with oncolytic herpes simplex virus 1 (HSV-1)...

BACKGROUND: The prognostic value of serum biomarkers in soft tissue sarcoma (STS) is limited, and its clinical applicability is compromised by a common inability to adjust for important confounders. The aim of this study was to determine the prognostic value of pretreatment biomarkers on disease-specific survival (DSS) adjusted for confounders. METHODS: The study included 818 patients with localized STS. Pretreatment levels of albumin, C-reactive protein, hemoglobin, neutrophils, and lymphocytes were tested individually and combined in prognostic scores: neutrophil/lymphocyte ratio (NLR), Glasgow Prognostic Score (GPS), and Aarhus Composite Biomarker Score (ACBS) which includes all five biomarkers...

PURPOSE OF REVIEW: Sarcomas are rare, heterogeneous group of soft tissue and bone tumors. Precise diagnosis of specific subtypes is challenging using conventional methods. Herein, we review the role of next-generation sequencing (NGS) technology that is used for rapid sequencing of DNA and RNA. RECENT FINDINGS: Recent sarcoma specific studies recommend that molecular genetic testing should be added at diagnosis for appropriate clinical management in addition to diagnosis by expert pathologists...

Rhabdomyosarcoma (RMS) is a malignant tumor of skeletal muscle origin and frequently involves the head and neck region. It represents the second most common pediatric soft tissue sarcoma and accounts for 3% of all childhood cancers. Here, we report a case of embryonal RMS presenting as a right-sided facial swelling in a 7-year-old boy. Histologically, the tumor consisted of classic embryonal rhabdosarcomatous areas with metaplastic cartilage, in both initial biopsy and final resection specimens. Cartilaginous metaplasia arising in the background of RMS is a rare finding, thus raising a diagnostic challenge...

Pediatric patients with recurrent, refractory or advanced soft tissue sarcoma (STS) who are simultaneously showing signs of cumulative treatment toxicity are in need of novel therapies. In this preclinical analysis, we identified ErbB2 as a targetable antigen on STS cells and used cytokine-induced killer (CIK) cells transduced with the lentiviral 2(nd)-generation chimeric antigen receptor (CAR) vector pS-5.28.z-IEW to target ErbB2-positive tumors. Solely CIK cell subsets with the CD3(+) T cell phenotype showed up to 85% cell surface expression of the respective CAR...

Cytotoxic drugs encapsulated into liposomes were originally designed to increase the anticancer response, while minimizing off-target adverse effects. The first liposomal chemotherapeutic drug was approved for use in humans more than 20 years ago, and the first publication regarding its use in a canine cancer patient was published shortly thereafter. Regardless, no general application for liposomal cytotoxic drugs has been established in veterinary oncology till now. Due to the popularity of canines as experimental models for pharmacokinetic analyses and toxicity studies, multiple publications exist describing various liposomal drugs in healthy dogs...

Dermatofibrosarcoma protuberans with fibrosarcomatous differentiation (DFSP-FS) is a rare soft tissue tumor with more aggressive behavior and it is not clear what causes this type of skin cancer. We describe the case of a 48-year-old woman who was born with a vascular malformation in the sternal region and presented suddenly with a soft tissue sarcoma (DFSP-FS) in the same territory. She was initially treated by embolization as the sarcoma was misdiagnosed but the tumor within 6 months seemed to be growing rapidly and reached a giant dimension with ulceration and required surgical intervention...

BACKGROUND: Alveolar Soft Part Sarcoma is a rare malignant tumor of uncertain histogenesis, representing 0.5-1% of all soft tissue tumors. It occurs predominantly in head and neck regions, especially the orbit and the tongue, in infants, causing no specific symptoms for an extended period of time. CASE: A four year old girl was brought to consultation because of persistent swelling of her left upper and lower eyelid for the past six months. A 4 mm proptosis was noted on her left eye with significant upwards displacement of the globe...

BACKGROUND/AIMS: Rhabdomyosarcoma, the most common pediatric soft tissue sarcoma, may show an intrinsic refractoriness to standard chemotherapy in advanced tumor stages, which is associated with poor prognosis. Cellular mechanisms conferring tumor cell survival and therapy resistance in many tumor types include the serum & glucocorticoid inducible kinase (SGK) 1 pathway, a kinase expressed ubiquitously with particularly strong expression in skeletal muscle and some tumor types. The present study explored whether SGK1 is expressed in rhabdomyosarcoma and, if so, whether this kinase impacts on tumor cell survival, proliferation and migration...

BACKGROUND: Survival estimates for soft tissue sarcomas (STS) and malignant bone tumors (BT) diagnosed in pediatric, adolescent, and young adult patients are not easily available. We present survival estimates based on a patient having survived a defined period of time (conditional survival). Conditional survival estimates for the short-term were calculated for patients from diagnosis to the first five years after diagnosis and for patients surviving in the long-term (up to 20 years after diagnosis)...
