Objective: To review our recent experience with primary retroperitoneal sarcomas, determine prognostic factors for disease recurrence and patient survival, and compare them to our previous results. Background: Medical therapies have shown little efficacy in the management of retroperitoneal sarcomas, making total surgical extirpation the best chance for patient cure. Methods: The case histories of all patients operated upon for retroperitoneal sarcomas between January 1983 and December 1995 were retrospectively reviewed. Results: Ninety-seven patients underwent attempted surgical resection of a primary retroperitoneal sarcoma. There were 54 (56%) men and 43 (44%) women, with a mean age of 59 years. Seventy-six (78%) patients underwent gross total resection, 13 (14%) had residual disease, and 8 (8%) underwent biopsy only with an actuarial 1-year survival of 88%, 51%, and 47%, respectively (P = 0.001). The actuarial 5- and 10-year survivals for patients who underwent gross total resection were 51% and 36%, respectively. Thirty-three patients (43%) developed locoregional recurrence, and 20 patients (26%) developed distant metastases at a median time of 12 months. The cumulative probability at 5 years was 44% for locoregional recurrence and 29% for distant metastases. On univariate analysis, factors associated with improved survival were complete resection of the tumor (P = 0.001), nonmetastatic disease at presentation (P = 0.01), low-grade tumors (P = 0.02), liposarcomas (P = 0.003), and no disease recurrence (P = 0.0001). Contrary to previous reports, the histologic subtype (P = 0.04) was the only significant factor predicting survival on multivariate analysis. Conclusions: Compared with our earlier experience, the rates of complete resection and overall survival have improved. Local control continues to be a significant problem in the management of retroperitoneal sarcomas. Because new surgical options for this problem are limited, further outcome improvement requires novel adjuvant therapies.
