摘要: We have studied 560 patients with osteosarcoma of a limb, who had been treated by neoadjuvant chemotherapy, in order to analyse the incidence local and systemic recurrence according type surgery undertaken. Of these, 465 limb-salvage procedure 95 amputation or rotationplasty. At median follow-up 10.5 years there 225 recurrences. The five-year disease-free survival overall rates were 60.7% 68.5%, respectively, no significant difference between undergoing those resection. was same for either limb salvage correlated significantly margins surgical excision histological response chemotherapy. outcome worse than recurrent disease metastases only. conclude that procedures are relatively safe They should, however, only be performed institutions where chemotherapy can accurately assessed. If inadequate is poor an immediate should considered.
