OBJECTIVE: To determine if chemotherapy offers a survival benefit to patients with large, high-grade, primary extremity liposarcoma. SUMMARY BACKGROUND DATA: The impact of chemotherapy on the survival of patients with primary extremity soft tissue sarcoma is controversial and its effect on individual histologic subtypes is not defined. PATIENT AND METHODS: Two prospectively collected sarcoma databases were used to identify all patients with >5 cm, high-grade, primary extremity liposarcoma that underwent surgical treatment of cure from 1975 to 2003 (n = 245). Clinical, pathologic and treatment variables were analyzed for disease-specific survival (DSS), distant recurrence-free survival (DRFS) and local recurrence-free survival (LRFS). RESULTS: Sixty-three (26%) patients were treated with ifosfamide based chemotherapy (IF), 83 (34%) with doxorubicin based chemotherapy (DOX) and 99 (40%) received no chemotherapy (NoC). To assess the impact of DOX, a contemporary cohort analysis of patients treated from 1975 to 1990 was performed. The 5 year DSS of the DOX treated patients was 64% (53%-74%) compared with 56% (51%-79%) for the NoC patients (log-rank P value = 0.28). To assess the impact of IF, a contemporary cohort analysis of patients treated from 1990 to 2003 was performed. The 5 year DSS of the IF treated patients was 92% (84%-100%) compared with 65% (51%-79%) for the NoC patients (log-rank P value = 0.0003). Independent prognostic factors for improved DSS were smaller size (HR...
