Popis: | Background : Adjuvant chemotherapy significantly improves survival of patients with non-metastatic osteosarcoma but most of the data come from trials conducted in major international cancer centres. Aim : To review the efficacy and toxicity of an adjuvant chemotherapy regimen used in two regional cancer centres in New Zealand. Methods : Retrospective review of patients treated for non-metastatic high-grade osteosarcoma of the extremities. The regimen (POMA) consists of high-dose methotrexate 8 g/m 2 and vincristine 1.5 mg/m 2 (maximum 2 mg) on days 1 and 8 followed by folinic acid then doxorubicin 50 mg/m 2 and cisplatin 100 mg/m 2 on day 15. This cycle was repeated every 35 days. Following amputation patients received six cycles while in selected patients two cycles were planned prior to limb salvage surgery followed by a further four cycles. Actuarial survival was calculated using the Kaplan-Meier method. Results : Twenty patients were treated with POMA between 1986 and 1993. Amputation was performed in 16 patients and limb-salvage surgery in four. Sixteen patients (80%) remain alive with no evidence of disease at a median follow-up of 40 months. Thirteen patients (65%) have been continuously disease-free. Actuarial survival at five years is 70%. Seven patients relapsed, six in lungs, of whom four underwent pulmonary metastasectomy ; three of these remain free of disease 31, 35 and 40 months later. There was no local relapse. The toxicity of POMA is significant but tolerable. Conclusion : The results obtained at two regional cancer centres in New Zealand using POMA compare favourably to those achieved in clinical trials performed at major international cancer centres.
