[New aspects in diagnosis and therapy of testicular tumors (author's transl)]

The prognosis of testicular tumors is largely depending on an early as possible tinning of the diagnosis. The present tumormakers do not bring a diagnostic security. However they are important for the continuing observation of the patients, especially of those with cytostatic chemotherapy. Today's acknowledged treatment of malignant testicular tumors is the high semicastratio, for Seninoms the additional highvoltage radiotherapy, for the Teratocarcinomas the additional retroperitoneal lymphnode extirpation and for the cases with retroperitoneal metastases the subsequent high-voltage radiotherapy and the adjuvant cytostatic chemitherapy. Between the alternative of the transperitoneal and the thoracoretroperitoneal lymphadenextomy we prefer the latter. The operation is radical, the thoracic complication are minimal and this technic besides advantages because the postoperative number of patients with a loss of ejaculation is much lower.
