Can chondrosarcoma metastasis?
Approximately 22%–32% of patients with chondrosarcoma develop metastasis. The rate of metastasis is related to histological tumor grade. Moreover, patients with large tumors, pelvic lesions, high-grade tumors, and local recurrence have been reported to be at high risk for metastasis and poor survival.
Where does chondrosarcoma spread to?
Chondrosarcoma primarily affects the cartilage cells of the femur (thighbone), arm, pelvis, or knee. Although less often, other areas (such as the ribs) may be affected. Chondrosarcoma is the second most common type of primary bone cancer.
How is metastatic chondrosarcoma treated?
Chemotherapy and radiotherapy may be used in dedifferentiated chondrosarcoma because distant systemic metastasis may be present at the time of diagnosis. However, current evidence indicates that surgery with clear margins remain the primary treatment for dedifferentiated chondrosarcomas as well.
What is metastatic chondrosarcoma?
Chondrosarcomas form a widely varying group of malignant bone tumors that have the common feature of producing cartilaginous chondroid matrix. We present a case of metastatic pulmonary chondrosarcoma, presenting as a rapidly-growing pulmonary mass with eccentric calcification.
How quickly does chondrosarcoma grow?
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.
How aggressive is chondrosarcoma?
Conventional chondrosarcoma and clear cell chondrosarcoma are often low to intermediate grade tumors that are not very aggressive and tend to stay in one place. Dedifferentiated and mesenchymal chondrosarcoma are high grade tumors that behave aggressively and tend to spread.
Is fibrosarcoma painful in dogs?
Whether single or multiple, there may be swelling of the affected area and pain. The pain may cause your dog to withdraw (become less sociable), refuse to be touched, or lose his appetite. If the leg is affected, there may be lameness, or difficulty getting up or lying down, or an inability to walk.
Why is my dogs occiput swollen?
Occipital dysplasia is a congenital abnormality of the formation of the occipital bones of the cranium. The most common manifestation of this condition is an underdeveloped occipital bone leading to a dorsoventrally enlarged (“keyhole shaped”) foramen magnum.
How fast can chondrosarcoma grow?
Chondrosarcoma is typically a slow-growing cancer, meaning it takes some time before it is formally diagnosed. Most often, it is identified when examining other areas of the body, then diagnosed with a biopsy. The slower chondrosarcomas grow, the less likely they are to metastasize in other parts of the body.
Does nasal chondrosarcoma metastasize in dogs?
Nasal chondrosarcoma may metastasize to adjacent sinuses or invade overlying bone and penetrate adjacent soft tissues. However, chondrosarcoma generally does not metastasize rapidly. But when it does the common sites that come within its ambit may include lungs, kidney, liver, heart and skeleton. The metastatic rate in dogs is 20%.
What is nasal and paranasal sinus chondrosarcoma?
Chondrosarcoma of the Nasal and Paranasal Sinuses in Dogs. A chondrosarcoma (CSA) is the second most common primary tumor in dogs, accounting for ten percent of all primary bone tumors. This is a malignant, invasive and fast spreading tumor in dogs.
What is chondrosarcoma of the bone?
Chondrosarcoma (CSA) of the bone is a fast spreading and malignant form of cancer, which, if not diagnosed and treated early, can be life threatening. Nasal and paranasal fibrosarcoma is characterized by a malignant tumor based in the connective tissue of the nasal passage or in the surrounding…
What is a nasal passage tumor in dogs?
Nasal passage tumors are a type of cancer that usually affects longer nosed dog breeds, or older animals, and are usually malignant (cancerous) in nature. Protect yourself and your pet. Compare top pet insurance plans.
