[Diagnosis and treatment of nonseminomatous germ cell tumors].

Testicular cancer currently shows excellent rates of curing and even in advanced stages of disease about 70% can be achieved. This was possible due to continuously carrying out studies. To reduce long-term toxicity the focus is now put on reduction of treatment. In nonseminomatous germ cell cancer this is discussed especially for stage I disease where different therapeutic strategies can be offered. Concerning advanced disease the aim is a further improvement of treatment results. Polychemotherapy and surgical procedures are equally important in this scenario. Concerning residual tumor resection it should always be considered that the procedure can be extended by adjuvant surgery, e.g. cava resection. Therefore, those resections should only be performed at centers where all possibly needed surgical disciplines are available.
