[Diagnosis and therapy of retroperitoneal tumors].

Upon detecting 112 retroperitoneal space reducing processes the authors operated on 62 adults with primary retroperitoneal tumours. Of them there were 12 benign and 50 malignant tumours. The diagnostics and complex therapy of these tumours are dealt with. It is established that although the CR, MR, and USG have resulted in a considerable development the therapeutic results are still not far better. In the surgical management of benign lesions total tumour exstirpation is recommended even with extensive multivisceral resections. For tumours of low grade malignancy the authors have the same standpoint. In case of retroperitoneal tumours of high grade malignancy--and a considerable number of patients belongs to this group--the ultraradical interventions are not associated with promising results therefore they are not recommended by the authors. In the complex management of primary retroperitoneal tumours the achievements of radio- and chemotherapy are nowadays rather only promising than notable.
