The percentage surgery and chemotherapy gave better survival of patients in stage III with metastases who had than chemotherapy only. We confirmed that good and excellent functional status Survival rate On the contrary, only The mortality rate and responsiveness Huvos grading. High mortality rate was those in amputation group.
Patients who did not found in patients with metastases compared to have metastasis and complication tended to have those who did not.
Thus, it is concluded that good and excellent functional scores. Current therapeutic strategies and Metastasis to the lung is the most common. Cancers Basel.

No advantage for neoadjuvant treatment was seen, but the amputation rate was unacceptably high by current standards. Cancer Treat Res , — Very intensive chemotherapy proved toxic and not obviously superior to standard schedules in this prospective but nonrandomized study. Accessed August 9, Updated information is available about a major international trial between four osteosarcoma study groups. Einhorn S, Strander H:Is interferon tissue specific? The result is that the median fluoride concentrations in bone samples of osteosarcoma patients and tumor controls are not significantly different.
Due to this tendency, high incidence of osteosarcoma is seen in some large dog breeds St. Bernards and Great Danes.
The tumor may be localized at the end of the long bone commonly in the metaphysis. Most often it affects the proximal end of tibia or humerus , or distal end of femur. The tumor is solid, hard, irregular "fir-tree," "moth-eaten", or "sun-burst" appearance on X-ray examination due to the tumor spicules of calcified bone radiating in right angles.
These right angles form what is known as a Codman triangle , which is characteristic but not diagnostic of osteosarcoma. Surrounding tissues are infiltrated. Tumor cells are very pleomorphic anaplastic , some are giant, numerous atypical mitoses. Tumor cells are included in the osteoid matrix.
Depending on the features of the tumor cells present whether they resemble bone cells, cartilage cells, or fibroblast cells , the tumor can be subclassified.
