BACKGROUND: Our aim was to review our experience with liposarcoma of the head and neck region. METHODS: This is a retrospective case series at a comprehensive cancer center (1945-2005). RESULTS: Of 30 patients, 10 (33%) were initially misdiagnosed. Local recurrences were common (overall rate = 53%), and 4 patients (13%) developed distant metastases. Decreased crude disease-specific survival rates were significantly associated with recurrence (especially distant recurrence [0%]), age less than 38 years (40%), and pleomorphic subtype (45%); however, in Kaplan-Meier analyses, only larger tumor size, negative margins, round cell subtype, and pleomorphic subtype were associated with significantly decreased disease-specific survival (log-rank test p = .048, .041, .021, and .012, respectively). CONCLUSIONS: Based on this limited experience and existing literature, we continue to recommend surgery with negative margins as the treatment of choice and that adjuvant therapies should be considered in patients with high-grade histology, large tumors, positive margins, or certain subsites.
