PURPOSE: Liposarcoma is one of the most common soft tissue sarcomas in adults. It is often low-grade and can occasionally involve neurovascular structures. We present the functional and oncological outcome resulting from planned marginal excision of a series of forearm low-grade liposarcomas with nerve involvement. METHODS: The Oxford tumor registry was used to identify cases of histologically proven, well-differentiated liposarcoma of the forearm, with nerve involvement, treated surgically between 1997 and 2006. Nerve involvement was identified clinically with symptoms or signs of nerve compression, or by images showing direct contact of the tumor with a nerve on magnetic resonance imaging. This was then further defined at the time of surgery as tumor abutting (capsular involvement) or encasing a peripheral nerve. Demographic and clinical data were collected and oncological outcome was assessed by noting local and distant recurrence during follow-up. Postoperative functional outcome was assessed using the Toronto Extremity Salvage Scores. RESULTS: Eight cases were identified, 6 with preoperative neurological symptoms. The total group comprised 6 men and 2 women with a mean age of 61 (range, 30-71) years. At surgery, all had their tumors successfully excised, with preservation of the involved nerves. In those with preoperative neurological symptoms, complete recovery occurred by 18 months after surgery. The average follow-up was 5 years (range, 3-9 y). There were no cases of either local or distant recurrence of disease, with a mean Toronto Extremity Salvage Score of 99%. CONCLUSIONS: Planned marginal excision of a well-differentiated liposarcoma, arising in the forearm and involving nerve, can result in excellent functional and oncological outcome. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.
