Abstract
Thirty-eight patients with locally recurrent soft-tissue sarcomas of various histologic types and grades but with no evidence of distant metastases were studied. Twenty-five patients had more than one local recurrence. Most primary lesions had been initially treated by simple or “wide local” excision with removal of little or no surrounding normal tissue. The most common site for recurrence was the extremity. Sixteen patients received preoperative intra-arterial Adriamycin (30 mg/day × three days) and radiation therapy (3500 R over ten days) followed by wide resection of the recurrence and the previous operative field. Tumor-free margins were confirmed microscopically. There were no subsequent local recurrences in this group. In five patients, no preoperative therapy was used, and the resection was incomplete because of proximity to vital structures. In these patients, postoperative radiation therapy and chemotherapy could not prevent continued local tumor progression. Amputation for control of local recurrence was necessary in only three patients. The remaining patients underwent either resection alone or resection in combination with postoperative radiation and/or chemotherapy. Life-table analysis of these 38 patients shows an unexpectedly high predicted five-year survival of 76% (87% for patients whose local recurrence could be completely resected). This high salvage rate clearly justifies aggressive treatment for patients with local recurrences alone and warrants attempts to salvage functional extremities.
