What is chondrosarcoma caused by?
What causes chondrosarcoma? The exact cause of chondrosarcoma is not known. There may be a genetic or chromosomal component that makes certain individuals more open to this type of malignancy. Chondrosarcomas have been observed as a late consequence of radiation therapy for other cancers.
Is chondrosarcoma serious?
Chondrosarcoma is a sarcoma, or malignant tumor of connective tissue. A chondroma, also called exostosis or osteochondroma, is a benign bone tumor. Benign bone tumors are not sarcomas. Benign bone tumors do not spread to other tissues and organs, and are not life threatening.
What does a chondrosarcoma feel like?
Chondrosarcoma: Symptoms Sharp or dull pain where the tumor is located. The pain usually is worse at night, and will become more constant as the bone cancer grows. The pain may increase with exercise, physical activity, or heavy lifting. Swelling or redness at the tumor site.
How does chondrosarcoma start?
Most often, chondrosarcoma starts in normal cartilage cells. It may also start in a noncancer (benign) bone or cartilage tumor.
What are the stages of chondrosarcoma?
The Enneking staging system for musculoskeletal sarcomas is applicable to chondrosarcomas, as follows : Stage I (low-grade tumor) – Stage I-A, intracompartmental; stage I-B, extracompartmental. Stage II (high-grade tumor) – Stage II-A, intracompartmental; stage II-B, extracompartmental. Stage III (distant metastasis)
How can chondrosarcoma be prevented?
There is no known way to prevent chondrosarcoma. People with uncommon bone-related conditions may be more likely to develop chondrosarcoma. Also, some scientists have noted a connection between chondrosarcoma and injury to the affected area.
Where does chondrosarcoma start?
Chondrosarcoma mainly affects the cartilage cells of the thighbone (femur), shoulder, or pelvis. Less often, it starts in the knee, ribs, skull, and windpipe (trachea). Chondrosarcoma is the second most common type of primary bone cancer in adults.
Where does chondrosarcoma grow on a bone?
It is a cancer of the cartilage cells. Cartilage is a tough but flexible material that covers the ends of the bones. This lets the bones move freely at the joints. Chondrosarcoma usually grows in a bone or on its surface.
How old is the average person with chondrosarcoma?
Find Support. Chondrosarcoma is a type of sarcoma that affects the bones and joints. It is a rare cancer that accounts for about 20% of bone tumors and is diagnosed in approximately 600 patients each year in the United States. 1 Chondrosarcoma typically affects adults between the age of 20 and 60 years old, and it is more common in men.
What kind of cancer is Grade 1 chondrosarcoma?
Grade 1 is low-grade cancer and grade 3 is high-grade cancer. Chondrosarcoma can sometimes develop into a faster-growing type of bone cancer called de-differentiated chondrosarcoma. the stage of the cancer – its size and whether it has spread outside the bone. We have more information about staging and grading bone cancer.
Which is the most difficult type of chondrosarcoma to treat?
Chondrosarcomas are further stratified into conventional, mesenchymal, dedifferentiated, and clear cell subtypes. Conventional chondrosarcoma represents around 85% of all chondrosarcomas and is notoriously difficult to treat with chemotherapy [ 1 ].
What is the life expectancy of someone with Stage 4 bone cancer?
Stage 4 bone cancer life expectancy. About 15 percent cases of bone cancer are diagnosed at stage 4 and bone cancer prognosis indicate nearly 32 percent survival rate at this stage.
What are the four stages of bone cancer?
For bone cancer there are 4 stages. Often the stages 1 to 4 are written as the Roman numerals I, II, III and IV. Generally, the higher the stage number, the more the cancer has spread. Talk to your doctor if you have questions about staging. The stages of bone cancer also depend on the grade.
What does chondrosarcoma mean?
Medical Definition of chondrosarcoma. : a sarcoma containing cartilage cells rarely arising as a primary tumor but more frequently developing as a secondary growth by malignant degeneration of a chondroma.
What is the survival rate for bone cancer?
Around 40% of bone cancer is diagnosed at an early stage. The 5-year survival rate for adult bone cancer is 66%. Adults with chondrosarcoma have a 5-year survival rate of 80% compared to a 5-year survival rate of 54% for osteosarcoma .
Chondrosarcoma is a rare type of cancer that usually begins in the bones, but can sometimes occur in the soft tissue near bones. Chondrosarcoma happens most often in the pelvis, hip and shoulder. More rarely, it can happen in the bones of the spine.
How does chondrosarcoma affect the body?
Chondrosarcoma mainly affects the cartilage cells of the thighbone (femur), shoulder, or pelvis. Less often, it starts in the knee, ribs, skull, and windpipe (trachea). Chondrosarcoma is the second most common type of primary bone cancer in adults. A primary bone cancer is one that starts from bone cells.
What are the different types of chondrosarcoma?
Different types of chondrosarcoma have been described, as follows:
- Conventional chondrosarcoma, which accounts for nearly 90% of all chondrosarcomas.
- Dedifferentiated chondrosarcoma.
- Clear cell chondrosarcoma.
- Mesenchymal chondrosarcoma.
- Juxtacortical chondrosarcoma.
- Secondary chondrosarcoma.
