0 a type of bone cancer that develops in the cartilage cells and usually affects the bones of the arms, legs, and pelvis and sometimes also the joints. It is malignant (= likely to cause death if not treated):
Usually originating in strong connective tissue, chondrosarcomas grow slowly.
The benign tumors are called chondroma, the malignant ones chondrosarcoma.
About 30% of skeletal system cancers are chondrosarcomas.
Abnormalities of chromosome 13 have been observed in canine osteoid chondrosarcoma and lymphosarcoma.
Unlike most chondrosarcomas, mesenchymal chondrosarcoma grows rapidly, tends to spread, and occurs more often in children and young adults than in older adults.
There are no blood tests currently available to enable an oncologist to render a diagnosis of chondrosarcoma.
Chemotherapy or traditional radiotherapy are not very effective for most chondrosarcomas, although proton therapy is showing promise with local tumor control at over 80%.
This approach is used to remove chordomas, chondrosarcoma, inflammatory lesions of the clivus, or metastasis in the cervical spine region.
In large, secondary chondrosarcoma arises at the site of osteochondroma due to increased thickness of the cartilage cap indicating potential malignant transformation.
