Abstract:
Germ cell neoplasms of the testis are rare solid tumors predominantly in young men. Seminomas are slightly more frequent than nonseminomatous germ cell tumors. A special feature of seminomas is that they are sensitive to radiation, so that this represents an option in tumor stages with few metastases; however, the guideline recommendation is cautious due to the increased risk of secondary malignancies. In nonmetastasized tumor stages active surveillance is the primary approach to avoid overtreatment of patients. This is also the reason for primary nerve-sparing retroperitoneal lymph node dissection in cases of a low metastasis load. This concept has already been implemented in the American Urological Association (AUA) and National Comprehensive Cancer Network (NCCN) guidelines, whereas in the European Association of Urology (EAU) guidelines it is still considered to be an individual approach.
