Chondrosarcoma is a malignancy. ItŐs a type of cancer that arises from cartilage cells. And cartilage is really that kind of smooth surface on the end of your bones that helps with gliding of the joints. Chondrosarcoma, like most bone cancers, starts with bone pain or a mass. The treatment options for chondrosarcoma are usually surgery alone. Cartilage tumors donŐt respond as well to radiation treatment and chemotherapy, and so typically surgery is the standard of care. Surgery for chondrosarcoma can be radical surgery, like an amputation. It can be limb salvage surgery, where we resect a portion of the bone and reconstruct the bone. And it can be less invasive surgery where we scrape out the tumor, and reconstruct the bone. Not a lot of surgeons are familiar or very comfortable doing resection of chondrosarcoma and reconstruction once the tumor is out. And so often times they go to a tertiary care center to seek a musculoskeletal oncologist, like myself here at UVA.
