OBJECTIVE: Osteosarcoma (OS) is one of the most common malignancies of bone. This study was aimed to explore the anti-metastatic effect of euxanthone on OS. MATERIALS AND METHODS: Adhesion assay and Transwell assay were used to examine the effect of euxanthone on adhesion, migration and invasion of OS cells. COX-2-over-expressing plasmid was applied to transfect OS cells to assess whether COX-2 affects the anti-metastatic function of euxanthone. PDCD4 knockdown and miR-21 mimic were applied to assess whether euxanthone suppresses the transactivation of c-jun via modulating miR-21-PDCD4 signaling...

BACKGROUND: The combination of gemcitabine and docetaxel (GT) has been demonstrated to be effective against various types of solid tumors, including sarcoma. However, the regimen has not been confirmed in large, well-designed clinical trials in refractory metastatic osteosarcoma. METHODS: We retrospectively reviewed the records of patients with refractory metastatic osteosarcoma at Peking University People's Hospital who were treated with gemcitabine (1000 mg/m2 ) intravenously (IV) on Day 1 and Day 8, and docetaxel (75 mg/m2 ) IV on Day 8, repeated every 21 days...

Osteosarcoma (OS) patients often exhibit pulmonary metastasis, which results in high patient mortality. Our present study established the doxorubicin (Dox) resistant human OS MG-63 and HOS cells and named them MG-63/Dox and HOS/Dox, respectively. The Dox resistant OS cells had greater invasion ability than that of parental cells. The expression of ZEB1, while not FOXM1, Snail, HIF-1α, or Sp1, was significantly increased in Dox resistant OS cells. Silencing of ZEB1 can attenuate the metastasis and increase Dox sensitivity of MG-63/Dox and HOS/Dox cells...

Although the investigation into biomarkers specific for pulmonary metastasis within osteosarcoma (OS) has recently expanded, their usage within the clinic remains sparse. The current screening protocol after any OS diagnosis includes a chest CT scan; however, metastatic lung nodules frequently go undetected and remain the primary cause of death in OS. Recently, screening technologies such as liquid biopsy and next-generation sequencing have revealed a promising array of biomarkers with predictive and diagnostic value for the pulmonary metastasis associated with OS...

Osteosarcoma is the most common primary malignancy of bone in children and young adults, the highest incidence peak is during adolescence and doesn't have any gender predominance. The main site of metastasis are the lungs and extrapulmonary cases are occasional. The incidence of metastasis in the Central Nervous System (CNS) is 2-6.5%, increase to 10-15% in patients with pulmonary metastases. Therefore, metastatic disease of the CNS is rare and the information on such patients is limited. Here, we describe a case of a 20-year old patient diagnosed with osteosarcoma in the left distal femur stage IIB, he developed pulmonary disease, during palliative chemotherapy experienced relapse to the brain classified as recursive partitioning analysis (RPA) class II, and was treated with external radiotherapy (30 Gy in 10 fractions) and later he had a poor evolution and died...

Osteosarcoma (OS) is one of most malignant bone tumors in early adolescence, which is a highly metastatic cancer and pulmonary metastasis is the most common cause of death. Thus, the development of efficient approaches to discover potential compounds that target metastasis of OS remains a topic of considerable interest. In this study, subtractive Cell-SELEX was performed to screen OS metastasis specific DNA aptamers by using cell lines with similar tumorigenic potentials but opposite metastatic aggressiveness (highly metastatic 143B cells and non-metastatic U-2 OS cells as the target and negative cells, respectively)...

BACKGROUND: Complete metastasectomy is the best predictor of survival in patients with osteosarcoma pulmonary metastases. There has been some controversy in the literature regarding the prognostic significance of the timing of occurrence of lung metastasis. METHODS: We reviewed the clinical course of all osteosarcoma patients with pulmonary metastases treated by metastasectomy in our hospital from January 2008 through December 2016. Each patient who underwent metastasectomy was placed into one of three groups based on whether lung metastases were present at initial presentation (Group 1), developed during chemotherapy (Group 2), or appeared after completion of chemotherapy (Group 3)...

Osteosarcoma (OS) is the most common pediatric malignant bone tumor, and occurrence of pulmonary metastasis generally causes a rapid and fatal outcome. Here we aimed to provide clues for exploring the mechanism of tumorigenesis and pulmonary metastasis for OS by comprehensive analysis of microRNA (miRNA), long non-coding RNA (lncRNA), and mRNA expression in primary OS and OS pulmonary metastasis. In this study, deep sequencing with samples from primary OS (n = 3), pulmonary metastatic OS (n = 3), and normal controls (n = 3) was conducted and differentially expressed miRNAs (DEmiRNAs), lncRNAs (DElncRNAs), and mRNAs (DEmRNAs) between primary OS and normal controls as well as pulmonary metastatic and primary OS were identified...

The loss of appropriate cell adhesion normally induces apoptosis via a process termed anoikis. The aim of this study was to investigate the effects of mesenchymal stem cells (MSCs) in the cancer microenvironment on the anoikis resistance and pulmonary metastasis of osteosarcoma (OS) cells, and to evaluate the critical role of the interleukin (IL)-8/C-X-C chemokine receptor (CXCR) 1/Akt-signaling pathway in these processes. Metastatic OS subtype cells, which did or did not interact with MSC-conditioned medium (MSC-CM) in vitro, were isolated from the pulmonary site and named Saos2-lung-M...

The Hedgehog (Hh) signalling pathway is involved in cell differentiation, growth and tissue polarity. This pathway is also involved in the progression and invasion of various human cancers. Osteosarcoma, a subtype of bone cancer, is commonly seen in children and adolescents. Typically, pulmonary osteosarcoma metastases are especially difficult to control. In the present paper, we summarise recent studies on the regulation of osteosarcoma progression and metastasis by downregulating Hh signalling. We also summarise the crosstalk between the Hh pathway and other cancer-related pathways in the tumourigenesis of various cancers...

Osteosarcoma is the most common primary bone malignancy. Recently, studies showed chemokine receptor 4 (CXCR4) played a critical role in osteosarcoma. However, the regulation of CXCR4 is not fully understood. microRNAs are short, non-coding RNAs that play an important roles in post-transcriptional regulation of gene expression in a variety of diseases including osteosarcoma. miR-613 is a newly discovered miRNA and has been reported to function as a tumor suppressor in many cancers. In this study, we confirmed that both Stromal Cell-Derived Factor (SDF-1) and CXCR4 could be prognostic markers for osteosarcoma...

Osteosarcoma (OS) pulmonary metastasis translates into poor patient survival. The implication of PD-1-PD-L1 pathway in the context of NK cells and/or macrophages in OS is unknown. We investigated the effect of anti-PD-1 in OS lung metastasis and the role of NK cells and/or macrophages in anti-PD-1 responses. A human LM7 OS mouse model was used. Immunohistochemistry for tissues (PD-L1, caspase-3, Ki-67, NK cells, macrophages), and Western blotting for OS lung tumors (p-Stat3, p-Erk1/2) was performed. NK and macrophages were assessed using flow cytometry...

Primary osteosarcoma (OS) of the uterus is distinctly rare. We report a case of primary uterine OS with pulmonary metastasis in a 74-yr-old woman. Histopathologic features of the uterine tumor were in keeping with a pure chondroblastic OS composed of neoplastic cells with osteoblastic/chondroblastic differentiation and neoplastic bone formation. Despite treatment with Doxorubicin and Olaratumab and later with palliative radiation therapy, the patient died 7 mo after hysterectomy due to multiple distant metastases...

BACKGROUND: Although metastasis is the major cause of mortality in patients with osteosarcoma, little is known about how micrometastases progress to gross metastatic disease. Clinically relevant animal models are necessary to facilitate development of new therapies to target indolent pulmonary metastases. Intratibial injection of human and murine osteosarcoma cell lines have been described as orthotopic models that develop spontaneous pulmonary metastasis over time. However, there is variability in reported injection techniques and metastatic efficiency...

The pulmonary metastasis assay (PuMA) is an ex vivo lung explant and closed cell culture system that permits researchers to study the biology of lung colonization in osteosarcoma (OS) by fluorescence microscopy. This article provides a detailed description of the protocol, and discusses examples of obtaining image data on metastatic growth using widefield or confocal fluorescence microscopy platforms. The flexibility of the PuMA model permits researchers to study not only the growth of OS cells in the lung microenvironment, but also to assess the effects of anti-metastatic therapeutics over time...

Osteosarcoma is rare and little improvement in survival rates has occurred in the last 25 years despite modern chemotherapeutic treatment. Bioluminescent cell lines for the modeling of osteosarcoma have shown success in tracking metastases in vivo, but commonly use adenoviral vectors to transfect the native cell line with bioluminescent reporters. The purpose of this study was to develop an orthotopic model for metastatic osteosarcoma capable of in vivo monitoring of metastatic and primary tumor burden in an immunocompetent mouse and compare that model to its wild type pathogenesis...
