The diagnosis and treatment of retroperitoneal lipomas and liposarcomas

Abstract

The paper analyzes the results of treatment in 29 patients with retroperitoneal lipomas (n = 5) and liposarcomas (n = 24). Among the patients with retroperitoneal lipomas, there were 3 patients with primary tumors and 2 with recurrent ones. There were 16 patients with primary liposarcomas and 8 with recurrent ones. Surgical treatment was performed in 26 patients. The survival rates after surgical treatment in patients with retroperitoneal lipomas varied from 3.5 to 17 years. Of them, 4 patients were reoperated on for tumor recurrences. After surgical treatment, recurrent liposarcomas were noted in 12 patients, 10 of them underwent radical surgery. The survival rates after surgical treatment in patients with retroperitoneal liposarcomas varied from 8 months to 12 years.
