Myeloid sarcoma is a rare presentation of acute leukemia as a solid tumor at various extramedullary sites. It may present concurrently, before or after the onset of systemic bone marrow leukemia. Unusual clinical localization may lead to misdiagnosis, or delayed diagnosis and treatment. We describe the first case, to our knowledge, of de novo myeloid sarcoma of the breast confirmed as acute promyelocytic leukemia. Immunohistochemical analysis, flow cytometry, fluorescent in situ hybridization analysis and molecular analysis using RQ-PCR of tissue samples should be routine in determining the correct diagnosis in this setting...

Programmed cell death-ligands 1 (PD-L1) is a key immune checkpoint protein and a promising therapeutic target for malignancy tumor immunotherapy. The prognostic value of PD-L1 in patients with bone and soft tissue sarcoma remains controversial. Therefore, this meta-analysis is conducted to evaluate the associations of PD-L1 expression with overall survival (OS), progression-free survival (PFS), and clinicopathological characteristics of sarcomaA comprehensive literature search of PubMed, Web of Science, Embase, and Cochrane Library was conducted for relevant studies...

BACKGROUND: Human osteosarcoma (OS) is one of the most common primary bone sarcoma, because of early metastasis and few treatment strategies. It has been reported that the tumorigenicity and self-renewal capacity of side population (SP) cells play roles in human OS via regulating of target genes. This study aims to complement the differentially expressed genes (DEGs) that regulated between the SP cells and the non-SP cells from primary human OS and identify their functions and molecular pathways associated with OS...

AIMS: Ewing sarcoma is a small round cell tumor that affects bone and soft tissues. Although the detection of the specific fusion gene is a robust method of its diagnosis, immunohistochemistry may serve as a practical surrogate. Recent tissue microarray studies suggested that PAX7 is a novel marker, because it was consistently expressed in Ewing sarcoma, in addition to rhabdomyosarcoma and synovial sarcoma. Here, we evaluated the utility of PAX7 immunohistochemistry in whole-tissue sections of an expanded array of round cell malignancies with adequate molecular characterization...

Background Ewing sarcoma (EWS) is the second most common bone cancer in pediatric patients. Angiogenesis is a major factor for tumor growth and metastasis. Our aim was to carry out a histological, immunohistochemical, and molecular characterization of the neovascularization established between xenotransplanted tumors and the host during the initial phases of growth in nude mice in three angiogenesis experiments (ES2, ES3, and ES4). Methods The original human EWS were implanted subcutaneously on the backs of three nude mice...

Synovial sarcoma (SS) is a malignant mesenchymal tumor with variable epithelial differentiation that affects mostly young adults and can arise at any anatomic site. Primary intrathoracic SS is very rare accounting for <0.5% of all lung tumors. Most commonly, it arises from the lung followed by pleura and mediastinum. Primary pulmonary SS (PPSS) affects both sexes equally with no preference for any hemithorax. The morphology, immunostaining properties, cytogenetic features, and management strategy of PPSS are similar to that of soft tissue SS...

Ewing sarcoma/peripheral primitive neuroectodermal tumor (ES/PNET) typically occurs in long or flat bones, soft tissues, or less often, solid organs. Ewing sarcoma/peripheral primitive neuroectodermal tumor arising from the adrenal gland is extremely rare, especially in children, and only limited cases are reported previously. Herein, we review a case of a 22-month-old girl who presented to our department with abdominal pain, bulging of the left flank, and a nonfunctioning adrenal lesion which was found to be an adrenal ES/PNET...

Myeloid sarcoma (MS), granulocytic sarcoma or chloroma, is defined as a localized extramedullary mass of blasts of granulocytic lineage with or without maturation, occurring outside the bone marrow. MS can be diagnosed concurrently with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS). The authors report a case of sacral MS occurring as a relapse of myeloid leukemia in a 5-year-old girl who was taken to the emergency department with radiculopathy symptoms.

Ewing sarcoma (EWS) is a soft tissue and bone tumor that occurs primarily in adolescents and young adults. In most cases of EWS, the chimeric transcription factor, EWS-FLI1 is the primary oncogenic driver. The epigenome of EWS cells reflects EWS-FLI1 binding and activation or repression of transcription. Here, we demonstrate that EWS-FLI1 positively regulates the expression of proteins required for serine-glycine biosynthesis and uptake of the alternative nutrient source glutamine. Specifically, we show that EWS-FLI1 activates expression of PHGDH, PSAT1, PSPH, and SHMT2...

Purpose: Osteosarcoma (OS) is the most common type of primary solid bone tumor. Ovo-like zinc finger 2 (Ovol2), a zinc finger transcription factor, is a mesenchymal-epithelial transition (MET) driver that induces miR-200 expression in prostate cancer, breast cancer, and hepatocellular carcinoma. However, little is known about the expression and function of MET in sarcomas, including OS. This study investigated the expression and clinicopathological significance of Ovol2 and its effect on MET in OS...

Osteosarcoma, Ewing sarcoma and chondrosarcoma are the three main entities of bone sarcoma which collectively encompass more than 50 heterogeneous entities of rare malignancies. In contrast to osteosarcoma and Ewing sarcoma which mainly affect adolescents and young adults and exhibit a high propensity to metastasise to the lungs, chondrosarcoma is more frequently observed after 40 years of age and is characterised by a high frequency of local recurrence. The combination of chemotherapy, surgical resection and radiotherapy has contributed to an improved outcome for these patients...

Ewing Sarcoma (ES) is a highly aggressive bone and soft tissue childhood cancer. The development of resistance to chemotherapy is common and remains the main cause of treatment failure. We herein evaluated the expression of genes associated with chemotherapy resistance in ES cell lines. A set of genes (CCAR1, TUBA1A, POLDIP2, SMARCA4 and SMARCB1) was data-mined for resistance against doxorubicin and vincristine, which are the standard drugs used in the treatment of patients with ES. The expression of each gene in SK-ES-1 ES cells was reported before and after exposure to a drug resistance-inducing protocol...
