When was osteosarcoma discovered
The recent discovery, by a team of South African scientists, of the presence of a bone tumour, likely to be an osteosarcoma, in a foot bone of an early human ancestor is believed to be the earliest identifiable case of cancer. This unique case in a specimen dated from an early human ancestor dated to more than 1.
Osteosarcomas consist of abnormal bone forming cells whose growth is uncontrolled. This abnormal bone was identified in the archaeological specimen. As the osteosarcoma grows patients will often present with pain as the abnormal bone is weak and may fracture, a palpable lump or unexplained limp. It would be expected that the human ancestor with the osteosarcoma in the foot bone would have had similar symptoms and signs.
Osteosarcoma originates from a bone cell, and is a rare malignant primary bone tumour affecting mainly adolescents and young adults. Despite several genetic alterations having been described in cancer cells, most osteosarcoma patients do not have any substantial risk factors. Osteosarcoma is not a recent disease; bone tumours including osteosarcoma have been previously reported in mummies.
Furthermore, osteosarcoma is not restricted to human species alone, and giant dogs which have physiological fast growth Leonberg, Irish Wolfhound, Rottweillers, Great Danes… are particularly prone to the development of osteosarcoma. Using this newer approach to identify potentially active agents, several recent studies testing new drugs called tyrosine kinase inhibitors have shown some promise.
At least 4 such type agents have been reported and two studies using a randomized approach testing regorafenib showed patients treated with this drug had improved early progression free survival. One study was conducted in Europe and one study was conducted in the U. Cabozantinib is a similar type of drug that seems to have some activity in recurrent OS. Based on the recent promising results testing several tyrosine kinase inhibitors in recurrent OS, we are encouraged that after years of negative results, we are at the beginning of a decade of promise in developing new approaches to improve the outcome of patients with OS, and OSI is confident that we can help accelerate this progress.

By Lee Helman, MD There has been a lack of improvement in outcomes for osteosarcoma patients over the last 40 years. As a physician who has dedicated […]. This method of treatment became standard practice in treating osteosarcoma patients. Close this module Before You Go. PET scans can be used to find small tumors that have spread or to check if treatment for a known tumor is working.
Complete blood count CBC. A measurement of size, number, and maturity of different blood cells in a specific volume of blood.
Biopsy of the tumor. A procedure in which tissue samples are removed with a needle or during surgery from the body for exam under a microscope to determine if cancer or other abnormal cells are present. Continued follow-up care to determine response to treatment, find recurrent disease, and manage the side effects of treatment.
Many patients, particularly those with higher-grade tumors, will receive a combination of treatments. A person who was treated for bone cancer as a child or adolescent may develop effects months or years after treatment ends.
These effects are called late effects. The kind of late effects one develops depends on the location of the tumor and the way it was treated. Some types of treatment may later affect fertility. If this side effect is permanent, it might cause infertility, or the inability to have children.
Both men and women can be affected. As with any cancer, prognosis and long-term survival can vary greatly from person to person. Every individual is unique and treatment and prognosis are structured around your needs.
Prompt medical attention and aggressive therapy are important for the best prognosis. Continuous follow-up care is essential for a person diagnosed with osteosarcoma.
Side effects of radiation and chemotherapy, including second cancers, can happen in survivors. New methods are continually being discovered to improve treatment and decrease side effects. Health Home Conditions and Diseases Sarcoma. What causes osteosarcoma?
