Objective: The existing literature of 18 F-FDG PET/CT in Ewing sarcoma investigates mixed populations of patients with both soft tissue and bone primary tumors. The aim of our study was to evaluate whether the maximum standardized uptake value (SUVmax) obtained with 18F-FDG PET/CT before and after induction chemotherapy can be used as an indicator of survival in patients with Ewing sarcoma originating exclusively in the skeleton. Materials and Methods: A retrospective database search from 2004-2011 identified 28 patients who underwent 18 F-FDG PET/CT before (SUV1, n= 28) and after (SUV2, n=23) induction chemotherapy...

Myeloid sarcoma (MS) is a localized tumor composed of premature precursors of granulocytic cells, which may occur in any organ and most commonly involves the soft tissue and musculoskeletal system. This malignancy may occur in the presence or absence of hematological disorders. Primary MS involving the central nervous system (CNS-MS) is rare, and has only been described in a small number of isolated case reports. The diagnosis of CNS-MS is challenging and strategies for its management are undefined. The present study describes 4 cases of CNS-MS...

BACKGROUND: Malignant peripheral nerve sheath tumor (MPNST) is one of the most common nonrhabdomyosarcoma soft tissue sarcomas encountered in pediatric age, and it is generally characterized by poor outcome, particularly for relapsing patients. MATERIALS AND METHODS: This study considered 73 patients <21 years of age with relapsing MPNST observed among 120 patients enrolled in Italian pediatric protocols from 1979 to 2004. With the aim of possibly establishing a risk-adapted stratification, patients' outcome was examined using univariate and multivariate analysis based on clinical features at onset, first-line treatments, clinical findings at the time of first relapse, and second-line treatments...

This prospective, noninterventional study is the first phase IV trial designed to evaluate trabectedin in patients with advanced soft tissue sarcoma in real-life clinical practice across Europe. To be included in the study, patients must have received more than or equal to one cycle of trabectedin and be currently on treatment. The primary endpoint was progression-free survival as defined by investigators. The secondary endpoints included objective response rate, disease control rate, time to progression and the growth modulation index (GMI), overall survival, and an assessment of the cancer-related symptoms and safety...

Rhabdomyosarcoma (RMS), a cancer characterized by skeletal muscle features, is the most common soft tissue sarcoma of childhood. While low and intermediate-risk groups have seen improved outcomes, high-risk patients still face a 5-year survival of <30%, a statistic that has not changed in over 40 years. Understanding the biologic underpinnings of RMS is critical. The developmental pathways of Notch and YAP have been identified as potent but independent oncogenic signals that support the embryonal variant of RMS (eRMS)...

Soft tissue sarcoma (STS) is a family of malignancies for which individual management decisions can be complex. There is a paucity of level 1 evidence, as the rarity and heterogeneity of STS pose challenges to the design and execution of randomized controlled trials. Radiotherapy (RT) is routinely used to facilitate function-preserving surgery and to improve local control. Delivery of RT in the preoperative setting can decrease chronic toxicities at the cost of increased wound complications in the short-term...

Advanced soft tissue sarcomas are aggressive cancers with limited therapeutic options. Recently, inhibition of platelet-derived growth factor receptor (PDGFR)-α by the monoclonal antibody olaratumab showed promising clinical activity. If confirmed, this would be one of the first examples of targeted therapy effective in advanced soft tissue sarcomas therapy independently of the histologic subtype. Here, we reviewed the biology of the PDGF/PDGFR axis, particularly focusing on its role in cancer, and then we discussed on the effects of PDGFR-α inhibition in the therapy of advanced soft tissue sarcomas...

Cutaneous leiomyosarcoma is an uncommon superficial soft tissue sarcoma and mainly found in the middle aged to elderly males. It can occur in any part of the body, mostly affecting the extremities and rarely affecting the face. It grows relatively slowly, can be diagnosed by biopsy and is treated by surgical excision. It needs to be distinguished from other spindle cell neoplasms, and immunohistochemical markers are usually required to attain an accurate diagnosis. We report a case of cutaneous leiomyosarcoma appeared on the left cheek within 6 month of a 73-year-old female patient suspected with malignant melanoma before surgery...

Dermatofibrosarcoma protuberans is a soft tissue sarcoma that is dermal in origin. The incidence is <0.1% of all malignancies and 1% of soft tissue sarcoma. Most commonly, it involves trunk (62%) followed by extremities (25%) and head and neck (13%). It is a slow growing tumor with locally aggressive behavior. Here, a 50-year-old female diagnosed with orbital dermatofibrosarcoma developed extra-axial component in right frontal region even on chemotherapy. Hence, the bad prognostic factors are yet to be established in dermatofibrosarcoma protuberans...

Myxoid and round cell liposarcoma (MRCL) is a common type of soft tissue sarcoma. The lack of patient-derived tumor xenograft models that are highly consistent with human tumors has limited the drug experiments for this disease. Hence, we aimed to develop and validate a patient-derived tumor xenograft model of MRCL. A tumor sample from a patient with MRCL was implanted subcutaneously in an immunodeficient mouse shortly after resection to establish a patient-derived tumor xenograft model. After the tumor grew, it was resected and divided into several pieces for re-implantation and tumor passage...

Soft tissue sarcomas (STS) constitute a rare tumour entity comprising over 50 histological subtypes. MicroRNAs (miRNAs) are short non-protein coding RNA molecules that regulate gene expression by targeting the 3'-untranslated region of messenger RNAs. They are involved in a variety of human diseases, including malignancies, such as endometrial cancer, osteosarcoma, bronchial carcinoma and breast cancer. In STS, various miRNAs are differentially expressed, thus contributing to development, progression and invasion...
