Randomized Controlled Trial Clinical Trial
A randomised phase II study on neo-adjuvant chemotherapy for 'high-risk' adult soft-tissue sarcoma.
The aim of this study was to examine the strategy, feasibility and outcome of neo-adjuvant chemotherapy, with doxorubicin and ifosfamide, in adult patients with 'high-risk' soft-tissue sarcomas. Patients with 'high-risk' soft-tissue sarcomas, defined as tumours > or =8 cm of any grade, or grade II/III tumours <8 cm, or grade II/III locally recurrent tumours, or grade II/III tumours with inadequate surgery performed in the previous 6 weeks and therefore requiring further surgery, were randomised between either surgery alone or three cycles of 3-weekly doxorubicin 50 mg/m(2) intravenous (i.v.) bolus and ifosfamide 5 g/m(2) (24 h infusion) before surgery. The type of surgery had to be planned at randomisation. ⋯ The 5 year overall survival for both arms is 64 and 65%, respectively (standard error 7%) (P=0.2204). Neo-adjuvant-chemotherapy with doxorubicin and ifosfamide at these doses and with this schedule was feasible and did not compromise subsequent treatment, surgery with or without radiotherapy. Although not powered to draw definitive conclusions on benefit, but with an at least 7 year median follow-up, the results render it less likely that major survival benefits will be achieved with this type of chemotherapy.
