    Abstract:
    BACKGROUND: Surgery plays a dominant role in the initial and subsequent treatment of retroperitoneal liposarcoma (RPLS). This study was a review of outcomes of patients treated at the Royal Marsden Hospital. METHODS: Records of all patients who had surgery for RPLS since 1990 were reviewed, with particular attention to local recurrence and disease-specific survival. Patients with primary RPLS and those with recurrent RPLS, who had palliative surgery after a variable number of operations performed elsewhere, were considered separately. RESULTS: Seventy-two patients had surgery for primary RPLS, over half of whom underwent resection of a contiguous organ to achieve clearance. Follow-up of at least 12 months was available for 58 patients. Thirty-four patients had no evidence of recurrence after median follow-up of 26 (range 12-151) months. Low-grade tumour and macroscopic clearance of tumour were significantly associated with a reduced risk of local recurrence and improved survival. Forty-seven patients had palliative surgery for recurrent RPLS. Median survival from time of last operation to death was 27 (range 0-79) months. Follow-up was to a median of 68 (range 14-261) months. CONCLUSION: Patients with low-grade RPLS that has been completely resected at the initial operation have the most favourable prognosis. Palliative resection is worthwhile to treat troublesome symptoms of recurrence.
