title: [Retroperitoneal tumors. Tactics, technics and surgical results].
abstract: Out of 33 cases of retroperitoneal tumours (TRP), collected throughout 11 years (1970-1981), 8 (24%) resulted benign, 25 (76%) malignant. Liposarcoma resulted the most frequent tumour. In 11 of the 25 cases of malignant TRP (44%), a radical removal of the tumour was performed; in 8 (32%), a palliative demolition, and in the remaining 6 (24%) a simple diagnostic laparotomy. In 10 of the 19 demolitive operations (53%) the removal was extended to contiguous organs: kidney, adrenal glands, colon, pancreas, spleen, bladder, stomach. The postoperative mortality was 6%. The cases of recurrence after operations considered radical were 5 (45%). Out of the 8 patients suffering from benign neoformations, 7 underwent simple removal, and result recovered. The global survival for malignant TRP was 20% after 5 years and 8% after 10 years; as related to the cases subjected to radical removal, it results 45% and 18% respectively. The Authors maintain the essential function of computerized axial tomography (TAC) in the preoperative anatomo-topographic outlining of the retroperitoneal mass and in the early recognition of the remote recurrences. An aggressive surgical behaviour seems to be presently the primary therapeutical solution; nevertheless, the encouraging results obtained through the complementary treatment (radiotherapy and chemotherapy) command the necessity of a pluridisciplinary management of the treatment of TRP as an essential condition for the improvement of the remote results.
