What is low grade chondrosarcoma?
Low-grade chondrosarcomas (LGCS) are tumours that grow slowly over time and do not generally metastasize and people do not usually die from this disease. In the late 20th century, the condition was treated by cutting out large portions of bone surrounding the tumour (wide resection).
What does chondrosarcoma look like?
The lytic lesion usually appears well-defined, associated with endosteal scalloping, and cortical thinning or thickening. High-grade tumours show irregular margins. Calcifications of the tumoral matrix may be punctate, flocculent, or have a ring-like pattern, they can be small, or disseminated, dense or subtle.
Can low grade chondrosarcoma spread?
The prognosis for chondrosarcoma patients varies by the grade of the tumor and the extent of surgery. In general, low grade tumors have an excellent prognosis, with a small chance of recurrence and virtually no chance of disease spread.
How can you tell the difference between chondrosarcoma and Enchondroma?
Enchondroma consists of regular lobules and mature connective tissue with low cellularity; well-differentiated chondrosarcoma is composed of irregular lobules with highly cellular fibrous tissue.
What is a grade 1 chondrosarcoma?
Grade I chondrosarcoma (syn.: atypical cartilaginous tumor) is classified as an intermediately and locally aggressive neoplasm and typically is treated less aggressively (i.e., by intralesional curettage).
Is chondrosarcoma slow growing?
Chondrosarcoma tends to grow slowly, so it might not cause signs and symptoms at first. When they occur, signs and symptoms of chondrosarcoma may include: Increasing pain. A growing lump or area of swelling.
What type of doctor treats chondrosarcoma?
Cancer surgeons who specialize in bone and soft tissue tumors (orthopedic oncologists) lead the care team for most people with chondrosarcomas.
Does chondrosarcoma show on bone scan?
Typically chondrosarcomas demonstrate increased uptake on bone scan, seen in over 80% of cases, and usually the uptake is quite intense.
What is a low grade cartilaginous lesion?
Low-grade malignant chondrosarcomas, which constitute the majority of malignant cartilage tumors, have been described as having a slow growth rate, infrequent metastases, and a 90% 5-year survival rate.
Does chondrosarcoma spread fast?
Most chondrosarcomas grow slowly and may not cause many signs and symptoms at first. Some rare types grow rapidly and have a high risk of spreading to other areas of the body, which can make these cancers difficult to treat.
What is the life expectancy of chondrosarcoma?
If the chondrosarcoma is detected early enough before it is able to spread and affect other organs, there is 90% chance of survival for a total period of 5 years. Once metastasis has occurred however, survival through the cancer is reduced to a mere 43%.
What is the survival rate for chondrosarcoma?
If the cancer is treated through aggressive methods that allow complete removal of tumors, the chances of long-term survival will usually reach around 50% to 75%. Treated cases of low grade chondrosarcoma will have better chances at survival compared to high grade tumors.
What is chondrosarcoma cancer?
Chondrosarcoma is a type of cancer closely related to bone cancer. However, chondrosarcoma forms in cartilage, the tough but flexible tissue that pads the ends of bones and lines joints, not in the bone tissue itself. This cancer usually develops in the cartilage that lines the bones of the pelvis, thigh, shoulder, ribs, or arm.
