Chondrosarcoma is a malignant (cancerous) tumor, typically found in the cartilage cells of the femur, arm, pelvis, knee, and spine. Rarely, this cancer may affect the ribs and other areas.
Chondrosarcoma also can originate at the skull base from the cartilage between the clivus and the petrous bone. This is called petro-clival synchondrosis.
As with all cancers, the prognosis or outcome depends upon how large the tumor is and whether it has spread to distant structures.
Chondrosarcoma most often occurs in people between 50 and 70 years old. It rarely affects people younger than 20. Males and females are at equal risk of developing chondrosarcoma.
Symptoms can include a large lump or mass on a bone, pressure surrounding the mass, or severe pain. Symptoms of chondrosarcoma of the skull base are neurological, and may include headaches, as well as vision or hearing disturbances.
At UPMC, the preferred surgical treatment for chondrosarcoma of the skull base is the Endoscopic Endonasal Approach (EEA). This innovative, minimally invasive technique uses the nose and nasal cavities as natural corridors to access hard-to-reach or previously inoperable tumors. Benefits of EEA include:
To make the diagnosis of chondrosarcoma, your doctor will ask you about your symptoms and medical history and perform a physical exam.
Symptoms of chondrosarcoma of the skull base (petro-clival synchondrosis) may include:
Diagnostic tests may include:
Surgery is the main treatment used to remove and treat chondrosarcomas of the skull base, or petro-clival synchondrosis.
Chondrosarcomas of the skull base may be approached directly using the Endoscopic Endonasal Approach (EEA).This state-of-the-art, minimally invasive approach allows surgeons to access the tumor through the natural corridor of the nose, without making an open incision. Surgeons then remove the chondrosarcoma through the nose and nasal cavities.
EEA offers the benefits of no incisions to heal, no disfigurement, and a faster recovery time.
If you need complementary treatments, such as radiation, those therapies can begin soon after EEA surgery.
Additional treatments for chondrosarcoma may include chemotherapy or radiation therapy.
