[Diagnostic parameters and their value in testicular tumors]

Diagnosis of the retroperitoneum to deliniate metastases of nonseminomatous germinal cell testicular cancer, when combined with Computer tomography, Sonography and Lymphography has a high specificity. With regard to treatment, the differentiation between stage I and stage II is very important. In the so called high risk groups (MTU-Tumour, T3-Primary tumour) a stage I can actually be a stage II. Computer Tomography of the thorax should be made to deliniate a stage III tumour.
