This 1982 NCI prospective RCT randomized 43 adults with high-grade extremity soft tissue sarcoma to limb-sparing resection plus radiation vs. amputation. A simultaneous 65-patient RCT evaluated adjuvant chemotherapy vs. observation. Both trials asked whether less radical surgery and systemic therapy could match the oncologic results of amputation.
Before this paper, amputation was the standard of care for high-grade extremity sarcoma. The prevailing assumption was that radical resection was required for oncologic control, and limb-sparing surgery was considered experimental.
This trial changed that. When you evaluate a patient with a high-grade extremity soft tissue sarcoma, the default question is no longer "do we amputate?" — it is "can we achieve negative margins with limb-sparing resection?"
If negative margins are achievable, limb-sparing surgery plus radiation is the standard. Roughly 85% of patients qualify. The 15% who do not. Those with disease so extensive that gross tumor cannot be cleared while preserving meaningful function. Still require amputation.
The margin lesson is non-negotiable: positive margins predict local recurrence (p<0.0001) and worse survival (p=0.007) regardless of radiation. Plan your resection to achieve clear margins. Radiation is an adjunct to adequate surgery, not a substitute for it.
