title: [Current principles of diagnosis and surgical treatment of non-organ retroperitoneal tumors].
abstract: The data on surgical treatment of 455 patients operated on for primary and recurrent non-organ retroperitoneal tumors (NRT) are discussed. 64.2% of tumors were resected; postoperative lethality was 8.2%. Particular emphasis is placed on the complex nature of diagnosis and an algorithm of examination is suggested. The sequence of main procedures and stages are described; 43% of radical procedures were performed in combination with one another. NRTs tended to relapse and malignant tumors recurred most frequently within the first 18 months. In the course of 182 operations, 54.4% of NRTs were resected: postoperative lethality was 11.1%. The end results were determined by a number of factors, primarily, nature of tumor (benign or malignant), tumor process (primary or recurrent), tumor size and histological pattern. Because of the poor end results, surgical procedures should be improved and their range should be extended.
