Abstract
Soft tissue sarcomas of the antecubital and popliteal space often involve the neurovascular bundle and are prone to recurrence after surgical resection. Amputation has frequently been performed for control of these tumors. A multimodality treatment program consisting of limb‐sparing resection, tumor‐bed radiation using temporary iridium 192 implants, and adjuvant chemotherapy for high‐grade lesions, has yielded satisfactory preservation of limb function and no local tumor recurrence in ten patients after a median follow‐up time of 5 years. Eight of the ten patients are still alive, five of whom beyond 5 years; six of the eight survivors had high‐grade tumors. These results are superior to those of 14 patients with similar tumors treated earlier by surgery alone: seven by amputation and seven by soft part resection; four of the latter resulted in local recurrence and all of the seven who had high‐grade sarcoma died of disease. Multimodality treatment including limb‐sparing resection merits consideration in the management of antecubital and popliteal soft tissue sarcomas. Cancer 57:1632–1639, 1986.
