Clinical and Pathologic data from 82 patients with retroperitoneal tumors treated from 1972 through 1987 were reviewed to determine clinical presentation, histologic features, treatment, pattern of recurrence, and prognosis. Initial presentation was palpable abdominal mass in 82%. Mean age was 47.2±12.2 years with 61 % of patients in 5th and 6th decades, and male to female ratio was 1:1.2: Mean size of tumor was 16. 7 ±9.0 cm. There were 56 malignant and 26 benign tumors and the ratio of malignant to benign tumors was 2.2:1. Liposarcoma, leiomyosarcoma, and lymphoma were most common malignant tumors and paraganglioma, neurilemmoma and teratoma were common benign tumors. USG, CT, I VP and colon study were common diagnostic methods and preoperative diagnosis was made in 83% of patients. 85 % of benign and 58% of malignant tumors were completely excised and local invasion to iliopsoas and major vessel was most common (75%) limiting factor to complete excision. Among 15 recurrent cases after resection, local recurrence was seen in 14 patients (93%). Survival of patients with retroperitoneal sarcoma was 52% at lyear, 30% at 2 years, 19% at 5 years. More than 70% recurred within 2 years. Between 3 grades of malignancy, significant difference in survival was noted.
