[Therapy of testicular tumors in childhood].

Between 1954 and 1984 41 primary testicular tumours were treated in 40 children at the age of 0 to 9 years as well as 9 secondary testicular tumours in malignant systemic diseases or metastases. The histological reclassification of the number of cases revealed 15 yolk-sac-tumours, 10 differentiated teratomas of immature subtype, 1 intermediary malignant teratoma, 3 undifferentiated malignant teratomas, 2 Sertoli-cell-tumours (1 double-sided) and 5 rhabdomyosarcomas. 2 children each with undifferentiated malignant teratomas and rhabdomyosarcomas died, all before 1970. 5 children with yolk-sac-tumours and 2 with rhabdomyosarcomas who since 1974 have been treated with Ablatio testis and combination chemotherapy live without tumour. Histological classification and division into stages are proved and form the basis of a therapy conception which in all testicular tumours apart from the Ablatio testis contains the chemotherapy of different intensity (HTK-84), taking into consideration form of tumour, stage and age of the children. The retroperitoneal lymphadenectomy is recommended only in the proof of metastases.
