INTRODUCTION: Amputation for localized extremity sarcoma (ES), once the primary therapy, is now rarely performed. We reviewed our experience to determine why patients with sarcoma still undergo immediate or delayed amputation, identify differences based on amputation timing, and evaluate outcomes. METHODS: Records of patients with primary, nonmetastatic ES who underwent amputation at our institution from 2001 to 2011 were reviewed. Univariate analysis was performed, and survival outcomes were calculated...

The viral Bcl-2 homolog (vBcl2) of Kaposi's sarcoma-associated herpesvirus (KSHV) displays efficient anti-apoptotic and anti-autophagic activity through its central BH3 domain, which functions to prolong the lifespan of virus-infected cells and ultimately enhances viral replication and latency. Independent on its anti-apoptotic and anti-autophagic activity, vBcl2 also plays an essential role in KSHV lytic replication through its amino-terminal 11-20 amino acids (aa). Here, we report a novel molecular mechanism of vBcl2-mediated regulation of KSHV lytic replication...

Kaposi's sarcoma-associated herpesvirus (KSHV) in vitro infection of dermal endothelial cell begins with its binding to host cell surface receptor molecules such as heparan sulfate (HS), integrins (α3β1, αVβ3 and αVβ5), xCT and EphA2 receptor tyrosine kinase (EphA2R). These initial events initiate dynamic host protein-protein interactions involving a multi-molecular complex of receptors, signal molecules (FAK, Src, PI3-K, RhoA-GTPase), adaptors (c-Cbl, CIB1, Crk, p130Cas and GEF-C3G), and actin/myosin II light chain that leads to virus entry via macropinocytosis...

Programmed death 1 (PD-1) and programmed death 1 ligand (PD-L1) pathway is a key mechanism of immune regulation, and its abnormal activation in tumor tissues suggests that PD-1/PD-L1 pathway may participate in the regulation of tumor immune escape. Driver gene mutation which is known as a key factor in the tumorigenesis of non-small cell lung cancer (NSCLC), was also reported to play a important role in the process of tumor immune escape. It indicates that there is an interaction between driver gene and PD-1/PD-L1 pathway...

Fungi of Pleurotus genus have attracted a great interest due to their medicinal properties such as anti-inflammatory, antimicrobial and antitumor. These properties are attributed mainly to polysaccharides synthesized by Pleurotus. This work aimed to study the mycelial growth of P. ostreatus in submerged culture, evaluating the influence of the initial concentration of substrate (20 and 40 g/L of glucose) and the pH (4 and 6) on kinetic parameters of production of biomass. The effectiveness of different doses (10, 30 and 50 mg/kg) of a mycelium polysaccharide fraction extracted from P...

Surgery is potentially curative for primary non-metastatic retroperitoneal soft tissue sarcomas (RPS), although patients remain at risk for local recurrence. To reduce this risk, the addition of radiotherapy to radical surgery may be considered. Nevertheless, level I evidence to support radiotherapy is currently lacking. The results from the EORTC-STBSG 62092-22092 studying this question are awaited. This manuscript addresses issues to consider when radiation-oncologists engage in a multidisciplinary treatment approach for RPS patients, including radiotherapy...

BACKGROUND AND OBJECTIVES: Synovial sarcoma is a rare soft tissue sarcoma with poor long-term prognosis due to late recurrence and metastasis. Synovial sarcoma arises in less than 6% from the shoulder. As a result, there is limited information in the literature about synovial sarcoma of the shoulder (SSS). METHODS: We included all patients treated for SSS at our institution between 1985 and 2013. Medical charts were retrospectively reviewed to collect demographics, information about the clinical course, and outcome...

In mouse skin models, mast cells have been shown to express vitamin D receptor (VDR) that can mediate the immunosuppressive effects of ultraviolet B radiation and vitamin D3. However, VDR activation leads to the expression of CYP24A1, a hydroxylase that can inactivate vitamin D3 metabolites. To examine immunoreactivity to VDR and CYP24A1 in mast cells from normal human skin, keratinocyte skin cancers, and disorders of chronic inflammation. Frozen biopsies were collected from the non-lesional and lesional skin of patients with actinic keratosis (AK), Bowen's disease/squamous cell carcinoma (SCC), basal cell carcinoma (BCC), and psoriasis...

Herpesviruses are a large group of DNA viruses infecting mainly vertebrates. Murine gammaherpesvirus 68 (MHV68) is often used as a model in studies of the pathogenesis of clinically important human gammaherpesviruses such as Epstein-Barr virus and Kaposi's sarcoma-associated herpesvirus. This rodent virus appears to be geographically widespread; however, its natural transmission cycle is unknown. Following detection of MHV68 in field-collected ticks, including isolation of the virus from tick salivary glands and ovaries, we investigated whether MHV68 is a tick-borne virus...

Sarcomas represent less than 1% of all malignant tumors found in the thyroid. Of these, primary extraosseoussarcoma has been reported only a few times in the past decade. We present the case of a 34-year-old male who had a fast-growing hard mass in the lower left neck. FNA was inconclusive. Core needle biopsy revealed the diagnosis of an Ewing sarcoma/primitive neuroectodermal tumor. Mutation of EWSR1 was confirmed using the FISH method. Following treatment by neoadjuvant chemotherapy, we observed clinical, radiological, and finally histopathological remission...

Pazopanib is US FDA approved for the treatment of advanced soft tissue sarcomas. All patients with this disease ultimately develop resistance to therapy. Mechanisms of resistance include activation of the mTOR, histone deacetylase (HDAC), MAPK, and ERBB4 pathways. We hypothesized that combining pazopanib with other targeted agents inhibiting these pathways would increase response rates. We retrospectively evaluated the safety and efficacy of pazopanib plus vorinostat, everolimus, lapatinib or trastuzumab, and MEK inhibitor in patients with advanced sarcoma...
