Staging of bone sarcomas is the process whereby patients are evaluated with regard to histology, as well as the local and distant extent, of disease. Bone sarcomas are staged based on grade, size, and the presence and location of metastases. The system is designed to help stratify patients according to known risk factors. Proper staging helps define the prognosis for patients and helps guide their treatment. Furthermore, staging allows meaningful comparisons to be done among groups of patients.
