ABSTRACT

BackgroundWe report the long-term outcomes of patients with osteosarcoma who underwent effective preoperative chemotherapy and subsequently underwent marginal resection.MethodsWe reviewed the records of 50 patients with osteosarcoma who underwent marginal resection following effective preoperative chemotherapy; 18 were treated with the MMIA (high-dose methotrexate (HD-MTX), adriamycin (ADR), ifosfamide (IFO)) and cisplatin (DDP), and 32 patients were treated with the DIA (DDP, ADR and IFO). protocol. The functions of the affected limb were evaluated using the revised MSTS93 system. The Kaplan-Meier method was used for survival analysis.ResultsAfter a median follow-up of 5.5 years, the rates were: overall 5-year cumulative survival 61.7%, event-free survival 57.7%, recurrence 8.5%, pulmonary metastases 42.6%, and excellent to good function of the affected limb 57.7%.ConclusionsOur results showed that marginal resection can be performed in patients with osteosarcoma who obtain clinically favorable responses to chemotherapy. Patients had a good clinical course and there was no negative effect on rates of survival or local recurrence.
