Long-term results of preoperative intra-arterial doxorubicin combined with neoadjuvant radiotherapy, followed by extensive surgical resection for locally advanced soft tissue sarcomas of the extremities.

Background and Purpose: In the 1980s a combined modality therapy of intraarterial doxorubicin, neoadjuvant radiotherapy and surgery was initiated at the Groningen University Hospital as a limb-saving treatment for locally advanced, primarily irresectable high-grade soft tissue sarcomas (STS) of the extremities. This study presents the short- and long-term results.
Patients and Methods: Between 1983 and 1987, 11 patients were treated with intraarterial doxorubicin, preoperative radiotherapy (10 x 3.5 Gy) and surgical resection. Non-radical resections received additional postoperative radiotherapy of 20-30 Gy.
Results: The limb-salvage rate was 91%, without local recurrences during a median follow-up of 84 months. Six patients died (55%); five from metastatic disease (45%). There were five long-term survivors with a median follow-up of 10 years. Three patients (60%) suffered serious late complications, resulting in disabilitating limb function.
Conclusion: Although this approach is feasible as a limb-saving treatment for these unfavorable STS, long-term morbidity is high.
