[The clinical predictors for the prognosis of patients with osteosarcoma]

Osteosarcoma is a kind of primary malignant tumor of bone originated from mesenchymal tissue, which mainly occurs in children and adolescents, and presents the characteristics of high malignancy, rapid growth, early metastasis and poor prognosis. Currently, most of the studies at home and abroad mainly focused on therapeutic procedures. However, reliable prediction indices or evaluation systems are also pivotal for monitoring disease change, guiding treatment and evaluating prognosis. Multiple clinical predictors have been reported to be related to the prognosis of osteosarcoma, which can be roughly divided into 9 categories according to their characteristics. Each kind of predictor owns its inherent advantage and disadvantage, and full understanding of them and their characteristics can be helpful to improve the prognosis of osteosarcoma.
