The metastatic dissemination is a complex multistep process by which tumor cells from a primary site enter into the systemic circulation to finally spread at distant sites. Even if this mechanism is rare at the tumor level, it remains the major cause of Osteosarcoma-patients' relapse and mortality. MicroRNAs (miRNAs) have recently been described as novel epigenetics' genes' expression regulators actively implicated in cancer progression and dissemination. The understanding of their implication in the metastatic spreading could help clinicians to improve the outcome of osteosarcoma...

Osteosarcoma is a highly malignant bone tumor. However, due to the high complexity of the occurrence and metastasis of osteosarcoma, the exact mechanism promoting its development and progression remains to be elucidated. This study highlights the causal link between solute carrier family 25 member 22 (SLC25A22) and the development, progression, and metastasis of osteosarcoma. SLC25A22 is upregulated in human osteosarcoma and predicts a poor prognosis. The upregulation of SLC25A22 in osteosarcoma tissues was significantly associated with cell proliferation, invasion, and metastasis...

Background: Bone morphogenetic proteins (BMPs), members of the TGF-β superfamily, are known to regulate cell proliferation, differentiation, apoptosis, chemotaxis, and angiogenesis. BMPs also participate in the development of most tissues and organs in vertebrates. Recombinant human (rh) BMPs, such as rhBMP-2, rhBMP-4, and rhBMP-7, have been recently approved to augment spinal fusion and recalcitrant long-bone non-unions because of their equivalent or superior efficacy to autogenous bone graft in enhancing bony fusion...

Cholangiocarcinoma is an aggressive tumor of the hepatic biliary system and it commonly spreads to the regional lymph nodes, liver and lungs. However, bone metastasis from cholangiocarcinoma is rare compared with other tumors. We herein present the case of a 61-year-old Asian woman who presented with pain in the right scapular area. Magnetic resonance imaging revealed bone destruction and an adjacent soft tissue mass at the right scapula. The findings on computed tomography imaging were compatible with cholangiocarcinoma...

Osteosarcoma (OS) is the most common primary bone malignancy, and the lung is the most frequent site of metastasis. The limited understanding of the tumoral heterogeneity and evolutionary process of genomic alterations in pulmonary metastatic osteosarcoma impedes development of novel therapeutic strategies. Here we systematically illustrate the genomic disparities between primary tumors (PT) and corresponding pulmonary metastatic tumors (MT) by multiregional whole-exome and whole-genome sequencing in 86 tumor regions from 10 OS patients...

Long non‑coding (lnc)RNAs have been demonstrated to be involved in the development of various types of cancers, such as osteosarcoma (OS). Long non‑coding (lnc)RNA metastasis associated lung adenocarcinoma transcript 1 (MALAT1) expression was reported to be highly expressed in OS and promoted the development of this disease; however, the underlying molecular mechanism by which MALAT1 promotes the progression of OS requires further investigation. In the present study, the expression of MALAT1 and miR‑34a was detected by reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR)...

Canine osteosarcoma is characterized by aggressiveness, easy metastasis to the lungs, and high mortality after standard therapy. Luteolin is a flavonoid found in vegetables and fruits and has diverse functions. Elucidation of the biological mechanisms of luteolin on canine osteosarcoma will enhance the efficacy of chemotherapeutic agents in canine tumors. In this study, we examined the effects of luteolin in the canine osteosarcoma cell lines, D17 and DSN. The results of this study show that luteolin inhibited canine osteosarcoma cell proliferation and induced apoptosis by altering cell-cycle proportion, producing reactive oxygen species, increasing the loss of mitochondrial membrane potential, and reducing cytosolic Ca2+ concentration...

Osteosarcoma (OS) is the most common primary aggressive and malignant bone tumor. Newly diagnostic OS patients benefit from the standard therapy including surgical resection plus radiotherapy and neoadjuvant chemotherapy (MAP chemotherapy: high-dose methotrexate, doxorubicin and cisplatin). However, tumor recurrence and metastasis give rise to a sharp decline of the 5-year overall survival rate in OS patients. Little improvement has been made for decades, urging the development of more effective therapeutic approaches...

Osteosarcoma (OS) is a common, malignant musculoskeletal tumor in young people. Neoadjuvant chemotherapy has improved the survival of osteosarcoma patients but with limited benefit due to metastasis. Tumor-associated macrophages (TAMs) are involved in various mechanisms of tumor biology, which include oncogenesis, drug resistance, and tumor immune escape, as well as tumor metastasis. In this study, we proved that TAMs possess the ability to promote OS cell migration and invasion by upregulating COX-2, MMP9, and phosphorylated STAT3 and to induce the epithelial-mesenchymal transition (EMT)...

BACKGROUND/PURPOSE: This study aimed to assess the significance of tumor debulking surgery by using immune checkpoint inhibitors for advanced pediatric solid tumors in a murine model of advanced osteosarcoma. METHODS: In C3H mice, 5 × 106 LM8 (osteosarcoma cell line with a high metastatic potential in the lungs originating from the C3H mouse) cells were transplanted subcutaneously. Thereafter, the mice were divided into 4 groups as follows: the control group received no intervention (CG, n = 5), the surgery group underwent subcutaneous tumor resection (tumor debulking surgery) 11 days after transplantation (SG, n = 10), the immunotherapy group received a cocktail consisting of 200 μg each of three antibodies (anti-Tim-3, anti-PD-L1, and anti-OX-86) intraperitoneally on posttransplantation days 11, 14, 18, and 21 (IG, n = 10), and the combination therapy group, tumor debulking surgery on day 11 and the cocktail intraperitoneally on days 11, 14, 18, and 21 (COMBG, n = 10)...

Chemo-resistance and lung metastasis have been the two obstacles in the osteosarcoma (OS) treatment, which is still lack of effective biomarkers for prediction, diagnosis and treatment. Circular RNA (circRNA) is a new type of endogenous noncoding RNA that could serve as ideal biomarkers in cancer because of its stable loop structure. However, little is known about the diagnostic value of circRNAs in OS as well as their associations with clinicopathologic characteristics of OS patients. In the current study, we identified a novel circRNA, hsa_circ_0081001, screened by the RNA sequencing in the three paired chemo-resistant and chemo-sensitive OS cell lines (MG63/DXR vs MG63, KHOS/DXR vs KHOS, U2OS/DXR vs U2OS), and found that hsa_circ_0081001 was significantly up-regulated in the OS cell lines, tissues and serums, associated with poor overall survival and cox multivariate analysis showed that hsa_circ_0081001 was a novel independent prognostic factor for OS patients...

Osteosarcoma is the most common primary bone tumor with highly invasive characteristic and low long-term survival. Recently, epithelial-mesenchymal transition (EMT) is reported as a key event in cancer invasion and metastasis. Oridonin, a bioactive diterpenoid, has been proved to possess anti-cancer effects. However, the effect of oridonin on EMT and metastasis of osteosarcoma is unclear. In this study, we investigated the underlying mechanism of oridonin on EMT and metastasis of osteosarcoma. We found that oridonin inhibited migration and invasion of MG-63 and 143B cells...

Primary bone cancers include osteosarcoma, Ewing sarcoma, and chondrosarcoma. They account for less than 1% of diagnosed cancers each year and are associated with significant morbidity and mortality. Timely diagnosis is challenging because of late patient presentation, nonspecific symptoms that mimic common musculoskeletal injuries, and low suspicion by physicians. Plain radiography is the preferred diagnostic test. Radiographic suspicion of a bone malignancy should prompt quick referral to a cancer center for multidisciplinary care...

BACKGROUND: Most instances of the parosteal osteosarcoma (OGS) are low-grade tumors. However, some parosteal OGSs undergo dedifferentiated transformation. Dedifferentiated parosteal OGS can cause distant metastasis and poor survival, and preoperative chemotherapy may be warranted. This study provides imaging clues for dedifferentiated parosteal OGS before treatment. METHODS: The study retrospectively enrolled 23 patients with histologically proven parosteal OGS, including 69...

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...
