Osteosarcoma is the most frequent primary malignant bone tumor among the children. The advent of neoadjuvant chemotherapy significantly improved the prognosis of patients with osteosarcoma in the 1980s, but it has since plateaued in the past decades. Recently, one of the most researched areas in sarcoma treatment is tyrosine kinases. Here, we describe research on a serine/threonine kinase, cycl...

osteosarcoma may rarely originate from the axial bones such as pelvis or vertebrae. in some pelvic and most vertebral primary tumors, resection often is not possible completely. in general, these tumors cannot be resected with negative margins so they need additional radiotherapy and chemotherapy, but results are unfavourable because of poor local control and high incidence of distant metastase...

Primary cardiac osteosarcoma is a very rare malignancy with a high incidence of local recurrence and systemic metastasis, contributing to the poor prognosis. Radiological modalities are commonly used for the evaluation of cardiac masses. 2-[18F]fluoro-2-deoxy-D-glucose ([18F]FDG) positron emission tomography/computed tomography is a valuable whole-body imaging modality in ...

Osteosarcoma is the most frequent malignant primary bone tumor and a main cause of cancer-related death in children and adolescents. Although long-term survival in localized osteosarcoma has improved to about 60% during the 1960s and 1970s, long-term survival in both localized and metastatic osteosarcoma has stagnated in the past several decades. Thus, current conventional therapy consists of m...

OBJECTIVE Osteosarcoma is one of the most common primary bone malignancies. Long non-coding RNAs (lncRNAs) have recently emerged as key regulators of osteosarcoma. The aim of present study was to explore the prognostic value of long non-coding RNA XIST (XIST) in osteosarcoma and XIST's relation to the cell proliferation in osteosarcoma in vitro. PATIENTS AND METHODS The XIST expressions were ...

PURPOSE Identification of new targeted therapies is critical to improving the survival rate of patients with osteosarcoma. The goal of this study is to identify kinase based potential therapeutic target in osteosarcomas. EXPERIMENTAL DESIGN We used a lentiviral-based shRNA kinase library to screen for kinases which play a role in osteosarcoma cell survival. The cell proliferation assay was us...

Osteosarcoma refers to a bone tumor and the term was introduced by John Abernathy in 1804 referring fleshy growth [1]. In 2009, Ottaviane G. et al reported that osteosarcoma is an aggressive malignancy arises from primitive transformed cells of mesenchymal origin produces malignant osteoid, which are most common representation primary cancer [2,3].

The long-term outcomes of osteosarcoma have improved; however, patients with metastases, recurrence or axial disease continue to a poor prognosis. Computer navigation in surgery is becoming ever more commonplace, and the proposed advantages, including precision during surgery, particularly applicable field orthopaedic oncology challenging areas such as skeleton. Within this article, we provide ...

While treatments for childhood osteosarcoma have improved, the overall survival for this common type of bone cancer has not changed for three decades, and thus, new targets for therapeutic development are needed. To identify tumor-related proteins in osteosarcoma, we used isobaric tags in a relative and absolute quantitation proteomic approach to analyze the differentially expressed proteins be...
