[The diagnosis and immediate treatment results in retroperitoneal tumors].

Immediate results of treatment of 20 patients with primary retroperitoneal tumors treated over a period of 5 years (1980-1985) at the Research Institute of Oncology in Sofia are reported. Attempt is made for anamnestic analysis, aimed at elucidating the semiotics of the disease. Analysis of the diagnostic methods serves to give recommendations for "first-rate" diagnostic procedure--computer tomography when a retroperitoneal tumor is suspected. Complex therapeutic approach consisting of radical operation and adjuvant radiation treatment is advised.
