Fibrosarcoma is a cancer that forms tumors on tissues that join muscles to bones. These are known as white tumors. White tumors originate from mesenchymal cells, which develop tissue in bones, cartilage, muscles, and fat. Fibrosarcomas appear mostly in the legs, arms, and pelvis. Fibrosarcoma is more common if someone has Gardner syndrome, Li-Fraumeni syndrome, or retinoblastoma. These are genetic conditions that run in families. Symptoms of fibrosarcoma often include lumps, swelling, and tenderness in areas where the tumors form.
Fibrosarcoma is most common between the ages of 30 and 40, but it can be found at any age. Diagnostic tests for fibrosarcoma include testing specific proteins in tumors, X-rays, biopsies, magnetic resonance imaging (MRI), computed tomography (CT) scans, bone scans, and blood count. Diagnosis is determined by ruling out other types of sarcomas. Fibrosarcoma tends to be a less aggressive type of sarcoma.
Treatment for fibrosarcoma varies depending on the location of the fibrosarcoma. It can include surgery, radiotherapy, chemotherapy, or amputation of the affected limb. Large tumors usually require chemotherapy to shrink the tumor before surgery can remove it. This is typically followed by rehabilitation of the affected area and follow up screenings for future tumors. If you or a family member has been diagnosed with fibrosarcoma, talk with your doctor about the most current treatment options as well as signs that you may need immediate medical attention.
