How long can patients with osteosarcoma live is mainly related to the time of discovery of osteosarcoma, pathological typing and treatment measures, which need to be analyzed on a case-by-case basis and cannot be generalized. Osteosarcoma is prevalent in adolescent stage and belongs to malignant tumor. If the patients are found early, the onset site is close to the distal part of the limbs, and there is no obvious metastasis, radical resection surgery can be carried out locally, and it is possible to prolong the survival period with chemotherapy after the surgery, and the 5-year survival rate can reach more than 50%. On the other hand, if the site of osteosarcoma is close to the trunk and distant metastasis or localized spread has occurred, it usually cannot be completely cured, and the survival time of patients may be 1-2 years, which is relatively short. Therefore, once the osteosarcoma is found, those who can be operated should be operated as early as possible, and should pay attention to regular follow-up after operation, once every 3-6 months, and once every year after 2 years if the condition is stable.
