Lung Metastases, Tumor Necrosis
Conditions
Brief summary
Zoledronic acid is an adjuvant treatment for primary osteosarcoma. Zoledronic acid has been widely used in the treatment of metastatic bone tumors. In addition to its inhibition of tumor osteoclasis, it also produces certain killing of tumor cells. effect. Foreign studies have shown that zoledronic acid also has a killing effect on osteosarcoma and has a certain inhibitory effect on distant metastasis. We hope that it can reduce tumor recurrence and lung metastasis through this study.

Inclusion criteria
* Patients with osteosarcoma who were diagnosed with initial pathology and pathology were excluded from lung metastasis or other metastatic lesions by CT and total body emission-computed tomography, and patients with standard chemotherapy were evaluated.
Exclusion criteria
* Pulmonary metastasis, pregnancy or lactation, renal insufficiency (creatinine clearance \<70 ml/min/1.73 m2), liver dysfunction, obvious oral disease, and unsuitable for bisphosphonate treatment after evaluation, have been found. With diseases that still require hormone therapy, abnormal blood system, heart disease
