    Journal: Surgery; 1989 Oct; 106(4):725-32; discussion 732-3. PubMed ID: 2799648.
    Abstract:
    The records of 116 adult patients who underwent operative treatment for retroperitoneal sarcomas at the Mayo Clinic during the years 1963 to 1982 were reviewed. Clinical, pathologic, and treatment variables were analyzed for their influence on recurrence and death from disease. Leiomyosarcomas, liposarcomas, and malignant fibrous histiocytomas represented 93% of the tumors. The primary tumor was completely excised in 54% of patients. Recurrent tumor developed in 68% of patients (median time to recurrence, 1.3 years). Tumor fixation to adjacent structures (T3 tumor) or a high-grade tumor (G2-4) identified patients at increased risk for recurrent disease. Five-year and 10-year survival rates were 40% and 22%, respectively. Survival was significantly better for patients who had (1) complete surgical excision of their tumors, (2) low-grade tumors (G1), (3) tumors not fixed to adjacent retroperitoneal structures (T1 and T2 sarcomas), and (4) tumors without metastases when initially seen. Complete surgical excision offers patients with retroperitoneal sarcomas the best chance for long-term survival, but recurrent disease remains a vexing problem. The therapeutic challenges in the treatment of retroperitoneal sarcomas continue to be the development of therapy that will increase the rate of complete resection, decrease the rate of local recurrence, and enhance patient survival.
