 Introduction: Malignant neoplasms of bones and articular cartilage resulting from the operation mesenchymal sales cell valuation bank. Cells can differentiate in many countries. in. chondrocytes, osteoblasts or adipocytes The bone cancer that occurs is osteosarcoma. In second place chondrosarcoma (chondrosarcoma).
 Materials methods: work was written based on development a ...

High grade chondrosarcoma is characterized by its lack of response to conventional cytotoxic chemotherapy, the tendency to develop lung metastases, and low survival rates. Research within the field prioritizes the development and expansion of new treatment options for dealing with unresectable or metastatic diseases. Numerous clinical trials using the proteasome inhibitor bortezomib have shown ...

UNLABELLED Pathologic fractures of the proximal femur resulting from primary bone sarcomas are often difficult to treat and some are often not recognized resulting in inappropriate interventions prior to the correct diagnosis being made. The aim of the study was to identify factors determining the survival after pathologic fractures of the proximal femur resulting from nonosteogenic primary bon...

Synovial sarcoma and high grade chondrosarcoma are characterized by their lack of response to conventional cytotoxic chemotherapy, the tendency to develop lung metastases, and low survival rates. Research within the field prioritizes the development and expansion of new treatment options for dealing with unresectable or metastatic diseases. Numerous clinical trials using histone deacetylases in...

The oncological outcome after lung metastasis in patients with chondrosarcoma of the extremities has not been reported. Between June 2000 and June 2013, 179 patients with chondrosarcoma in the extremities were treated at eleven hospitals. Twenty consecutive patients (11.2%) developed lung metastases after initial treatment of primary chondrosarcoma in the extremities. We investigated the oncolo...

Chondrosarcoma is the third most common primary bone malignancy, but its thoracic presentation unusual compared to pelvis and extremities. Chest wall chondrosarcomas are difficult be surgically resected due their proximity neurovascular structures. We report case of a 48-year-old man presenting with history chest bulging. Computed tomography showed lesion approximately 12 cm in sagittal axis ad...

We explored the general feasibility of proton beam therapy for chordoma and chondrosarcoma of the skull base. Clinical records and treatment-planning data of patients with the pathological diagnosis of chordoma or chondrosarcoma were examined. Proton beam therapy was administered for gross tumor mass as well as microscopic residual disease after surgery. The prescribed dose was determined to ma...

BACKGROUND G-CSF is known to function as a hematopoietic growth factor and it is known to be responsible for leukocytosis. G-CSF-producing tumors associated with leukocytosis include various types of malignancies. CASE PRESENTATION We report the case of a 72-year-old man with dedifferentiated chondrosarcoma characterized by dedifferentiated components of malignant fibrous histiocytoma- or ost...

Chondrosarcoma is one of the bone tumor with high mortality in respond to poor radiation and chemotherapy treatment. Here, we analyze the antitumor activity of a novel benzofuran derivative, 2-amino-3-(2-chlorophenyl)-6-(4-dimethylaminophenyl)benzofuran-4-yl acetate (ACDB), in human chondrosarcoma cells. ACDB increased the cell apoptosis of human chondrosarcomas without harm in chondrocytes. AC...

Chondrosarcoma is the second most prevalent general primary tumor of bone following osteosarcoma. Chondrosarcoma development may be linked to angiogenesis, which is principally elicited by vascular endothelial growth factor-A (VEGF-A). VEGF-A level has been recognized as a prognostic marker in angiogenesis. WNT1-inducible signaling pathway protein-3 (WISP)-3/CCN6 belongs to the CCN family and i...
