Treatment and local control of primary extremity soft tissue sarcomas.
OBJECTIVE
Modern series of adult extremity soft tissue sarcomas utilize combinations of modalities in all patients. Remaining questions: 1) is it necessary to strive for wide margins in the multimodality era; 2) to use adjuvant therapy in every high-grade sarcoma? 3) Does previous partial or marginal resection seriously interfere with the definitive resection?


METHODS
In a retrospective review of 194 extremity soft tissue sarcomas (1977-1994), limb preservation was possible in 181/194 (93%) of cases. Patients with narrow margins received adjuvant radiation. Some patients were referred after partial (n = 39) or "complete" (n = 63) excision.


RESULTS
Local recurrence was observed in 181/141 (13%) of patients treated with wide or compartmental resection, and in 10 of 42 (24%) of those treated with conservative resection plus radiation (P = 0.14). The 5-year survival rate for grade III, >/=5-cm sarcomas was not significantly different (P = 0.82) with adjuvant (46%) or without (48%) adjuvant systemic chemotherapy. Five-year survival varied (P = 0.0001) according to grade. Patients referred with partial, or "complete" (63%, 38/63, had residual tumor at reoperation) excision had a local recurrence rate of 8% and 6%, and 5-year survival rates of 75% and 84%, respectively.


CONCLUSIONS
1) It is important to strive for wide margins even when adjuvant radiation is intended. 2) When a wide margin is possible, adjuvant radiation may not be necessary. 3) Adjuvant systemic chemotherapy may be considered for high-grade tumors, preferably within a prospective protocol. 4) A partial or "complete" excision of the tumor before referral to a tertiary center does not appear to compromise the limb preservation, local control, or survival rates of these patients.
