In order to explore the potential of immune checkpoint blockade in sarcoma, we investigated expression and clinical relevance of programmed cell death-1 (PD-1), programmed death ligand-1 (PD-L1) and CD8 in tumors of 208 sarcoma patients. Primary untreated osteosarcoma (n = 46), Ewing sarcoma (n = 32), alveolar rhabdomyosarcoma (n = 20), embryonal rhabdomyosarcoma (n = 77), synovial sarcoma (n = 22) and desmoplastic small round cell tumors (DSRCT) (n = 11) were examined immunohistochemically. PD-L1 expression was predominantly detected in alveolar and embryonal rhabdomyosarcomas (15% and 16%, respectively)...

PURPOSE: To determine the impact of surgery and/or radiation therapy on distant metastatic sites (DMS) in children with stage IV rhabdomyosarcoma (RMS). METHODS: A retrospective chart review was conducted on all patients with stage IV RMS at Texas Children's Hospital from 1992 to 2012. Data analyzed included age, gender, primary site, histologic subtype, number and sites of metastases, treatment including local therapy to DMS, and Oberlin score. RESULTS: The 5-year progression-free survival (PFS) and overall survival (OS) rates were 20% and 25%...

The use of immunohistochemical (IHC) staining in determining and/or confirming the cellular origin of poorly differentiated sarcomas was evaluated in this study. Sarcomatous neoplasms were evaluated in a research study conducted in 2 strains of p53+/- haploinsufficient mice. The most common neoplasms were undifferentiated sarcomas, followed by osteosarcomas and rhabdomyosarcomas (RMSs). The RMSs were poorly differentiated and appeared similar to the pleomorphic, or adult type, RMS of humans. All sarcomas stained positive by IHC for the mesenchymal cell intermediate filament vimentin...

Anaplastic lymphoma kinase (ALK) is a receptor tyrosine kinase that is often overexpressed in rhabdomyosarcoma (RMS). However, its oncogenic and functional role in RMS remains unclear. Therefore, we investigated the antitumor activity of LDK378 (ceritinib), a new second-generation ALK inhibitor approved for patients with ALK-positive non-small-cell lung cancers. Here, we report that LDK378 reduces cell viability and induces cell death in RMS cell lines at low micromolar IC50 concentrations irrespective of ALK expression levels or phosphorylation status...

Alveolar rhabdomyosarcoma (ARMS) commonly occurring in children and adolescents, is a rare and aggressive soft tissue malignancy. Here, a rare case of pleural ARMS is reported in a boy presenting dyspnea for two weeks. The pathology of a biopsy specimen from pleura showed ARMS. PAX3-FKHR fusion protein is positive and the PAX7-FKHR fusion protein is negative as detected by fluorescence in situ hybridization. The prognosis of this patient was poor and nonresponsive to chemotherapy.

Transcription factor AP-2β (TFAP2B) regulates embryonic organ development and is overexpressed in alveolar rhabdomyosarcoma, a rare childhood malignancy. Gene expression profiling has implicated AP-2β in breast cancer (BC). This study characterizes AP-2β expression in the mammary gland and in BC. AP-2β protein expression was assessed in the normal mammary gland epithelium, in various reactive, metaplastic and pre-invasive neoplastic lesions and in two clinical BC cohorts comprising >2000 patients. BCs from various genetically engineered mouse (GEM) models were also evaluated...

Oncolytic viruses are an emerging class of cancer therapeutics that couple cytotoxicity with the induction of an anti-tumor immune response. Host-virus interactions are complex and modulated by a tumor microenvironment whose immunosuppressive activities can limit the effectiveness of cancer immunotherapies. In an effort to improve this aspect of oncolytic virotherapy, we combined the oncolytic herpes virus HSV1716 with the transforming growth factor beta receptor 1 (TGF-βR1) inhibitor A8301 to treat syngeneic models of murine rhabdomyosarcoma...

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...

Hypoxia is a common feature of solid tumors, which translates into increased angiogenesis, malignant phenotype cell selection, change in gene expression and greater resistance to radiotherapy and chemotherapy. Therefore, there is a need for markers of hypoxia to stratify patients, in order to personalize treatment to improve therapeutic outcome. However, no modality has yet been validated for the screening of hypoxia in routine clinical practice. Magnetic resonance imaging (MRI) R1 and R2 * relaxation parameters are sensitive to tissue oxygenation: R1 is sensitive to dissolved oxygen and R2 * is sensitive to intravascular deoxyhemoglobin content...

Urinary bladder masses are rare in children, and the associated histologic features and prognoses in this population are different from those in adults. Most children with urinary bladder masses present with lower urinary tract symptoms, which may include hematuria, dysuria, frequent urination, and urgency to urinate. However, some of these masses may be identified incidentally or involve generic symptoms such as abdominal distention. In general, pediatric bladder tumors can be divided into those that originate from the bladder epithelium, known as urothelial neoplasms, and mesenchymal bladder neoplasms, which are more prevalent...

A wide range of masses develop in the nose, nasal cavity, and nasopharynx in children. These lesions may arise from the nasal ala or other structures of the nose, including the mucosa covering any surface of the nasal cavity, the cartilaginous or osseous portion of the nasal septum, the nasal turbinates, and the nasal bones. Lesions may also arise from the nasopharynx or adjacent structures and involve the nose by way of direct extension. The causes of nasal masses in children include congenital and developmental disorders such as congenital nasolacrimal duct mucocele, dermoid cyst, cephalocele, and nasal neuroglial heterotopia; inflammatory and infectious processes such as mucocele, polyp, and pyogenic granuloma; benign neoplasms such as infantile hemangioma and juvenile nasopharyngeal angiofibroma; malignant lesions such as rhabdomyosarcoma and nasopharyngeal carcinoma; and masses related to prior trauma such as septal hematoma...

AIMS: Malignant ectomesenchymoma is a rare pediatric neoplasm with dual mesenchymal and neuroectodermal elements. Mesenchymal component is usually rhabdomyosarcoma, particularly embryonal subtype, whereas neuroectodermal derivatives are frequently a neuroblastic tumor. Ectomesenchymoma manifests in various sites given the wide migration of neural crest cells during development, though the pelvis/perineum is most often involved. Moreover, no unique unifying molecular abnormality has been determined...

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: This study evaluated the utility of Phox2b in pediatric tumors. Previously tyrosine hydroxylase (TH) was the most widely utilized sympathoadrenal marker specific for neural crest tumors with neuronal/neuroendocrine differentiation. However, its sensitivity is insufficient. Recently Phox2b has emerged as another specific marker for this entity. METHODS: Phox2b IHC was performed on 159 pediatric tumors including (1) 65 neural crest tumors with neuronal differentiation [peripheral neuroblastic tumors (pNT)]: 15 neuroblastoma undifferentiated (NB-UD), 10 NB poorly differentiated (NB-PD), 10 NB differentiating (NB-D), 10 ganglioneuroblastoma intermixed (GNBi), 10 GNB nodular (GNBn), and 10 ganglioneuroma (GN); (2) 23 neural crest tumors with neuroendocrine differentiation [pheochromocytoma/paraganglioma (PCC/PG)]; (3) 27 other neural crest tumors including one composite rhabdomyosarcoma/neuroblastoma; and (4) 44 non-neural crest tumors...

BACKGROUND: EPH (erythropoietin-producing hepatocellular) receptors are clinically relevant targets in several malignancies. This report describes the effects of GLPG1790, a new potent pan-EPH inhibitor, in human embryonal rhabdomyosarcoma (ERMS) cell lines. METHODS: EPH-A2 and Ephrin-A1 mRNA expression was quantified by real-time PCR in 14 ERMS tumour samples and in normal skeletal muscle (NSM). GLPG1790 effects were tested in RD and TE671 cell lines, two in vitro models of ERMS, by performing flow cytometry analysis, Western blotting and immunofluorescence experiments...

Rhabdomyosarcoma (RMS) is a soft tissue sarcoma and is most frequently found in children. In RMS, there are two major subtypes, that is, embryonal RMS and alveolar RMS (ARMS). ARMS has exclusively the worse prognosis and is caused by formation of the chimeric PAX3-FOXO1 gene. Regarding cancer, the Warburg effect is known as a feature of cancer-specific metabolism. Polypyrimidine tract-binding protein 1 (PTBP1), a splicer of pyruvate kinase muscle (PKM) mRNA, is a positive regulator of cancer-specific energy metabolism...

Rhabdomyosarcoma (RMS) cells have recently been reported to be sensitive to oxidative stress. Therefore, we investigated whether concomitant inhibition of the two main antioxidant defense pathways, that is, the thioredoxin (TRX) and the glutathione (GSH) systems, presents a new strategy to trigger cell death in RMS. In this study, we discover that GSH-depleting agents, i.e. γ-glutamylcysteine synthetase inhibitor, buthionine sulfoximine (BSO) or the cystine/glutamate antiporter inhibitor erastin (ERA), synergize with thioredoxin reductase (TrxR) inhibitor auranofin (AUR) to induce cell death in RMS cells...
