The 5-year survival rate for patients who remain after regular treatment for osteosarcoma is about 50%-70%, and if survival exceeds 5 years, it suggests a good prognosis. Osteosarcoma is one of the tumors with very high malignancy in orthopedics and has a very poor prognosis. If there is no metastasis and the cross-sectional level is high and thorough, it can be well controlled. Generally, no recurrence after 5 years is designated as clinical cure and considered as no more recurrence. Even if the disease is reoccurring, it has nothing to do with the last tumor and is new, which is the medical definition. It is recommended to take oral multivitamin element tablets, supplement multivitamins and trace elements, and keep an optimistic attitude, the effect is very good.
