This single-institution study analyzed 1,041 adults with localized extremity soft tissue sarcoma treated at MSKCC from 1982 to 1994. Using prospectively collected data, it identified independent prognostic factors for four separate end points: local recurrence, distant recurrence, disease-specific survival, and postmetastasis survival.
When you evaluate an extremity soft tissue sarcoma, stop thinking of one risk score. Local control and systemic risk track different factors and must be assessed separately. High grade is the engine of metastasis (RR 4.3 overall, 7.6 within 30 months), so grade drives your decision about systemic adjuvant therapy and the intensity of early surveillance.
Positive margins and recurrent presentation are the actionable local-control levers. A positive margin here predicts not just local failure but tumor-related death, likely a marker of aggressive infiltrative biology, so margin status belongs in your operative goals and re-excision discussions.
Histologic subtype carries independent weight beyond size, grade, and depth. Leiomyosarcoma and MPNST worsen survival, while liposarcoma is protective. Practically: a large, high-grade, deep tumor or one presenting as a local recurrence flags the patient who should be considered for systemic adjuvant trials.
