title: Long-term results of aggressive surgical treatment of primary and recurrent retroperitoneal liposarcomas.
abstract: The aim of this study was to establish the role of surgery in the treatment of retroperitoneal liposarcomas. Data concerning 28 patients submitted to surgery for retroperitoneal liposarcoma in our department over the period from 1972 to 1999 were reviewed retrospectively and analysed. Seventy-four operations were performed; in 54% of the operations it was necessary to resect contiguous organs (kidney 60%, colon 50%, adrenal gland 35%). In 89%, grossly curative resection was achieved at the first operation; 20 patients had at least one local recurrence after first operation (median time interval: 22 months). The mean follow-up was 80 months; median survival time was 51 months and 5-year actuarial survival time 51%. Patients with low-grade liposarcoma showed a statistically significant improvement (P < 0.001) in median survival (153 months) versus those with medium- (37 months) and high-grade sarcomas (8 months). At present surgery is still the treatment of choice in the treatment of primary and recurrent liposarcoma; in the case of low-grade liposarcomas especially, an aggressive surgical approach can result in long-term survival.
