✦ Synopsis

Testicular germ-cell tumors are relatively rare in childhood and adolescence, accounting for only 3.9% of all neoplasms. However, they have become a model for curable cancer. Furthermore, most of them have accurate serum markers [beta-human chorionic gonadotropin and alpha-fetoprotein], which provide in clinical stage I disease after semicastration a "wait and see" program. MAHO 82, 88, and 92 were cooperative studies on the treatment of testicular germ-cell tumors in childhood and adolescence. Between 1982 and 1993, 137 patients were registered. In all, 76 patients suffered from yolk-sac tumors (YST); 30, from differentiated teratomas (TD); 29, from malignant teratomas of either intermediate (MTI), undifferentiated (MTU), or trophoblastic type (MTT); and 2, from seminomas. All patients received semicastration. Chemotherapy was given to 53 patients on the basis of disease stage and histology. Standard therapy consisted of four courses of vinblastine, bleomycin and cisplatin. However, if viable tumor was suspected after two courses, delayed laparotomy was performed (seven patients). If there was then complete tumor regression, standard therapy was continued (four patients). If there was an incomplete tumor response, the patients received as salvage therapy three courses of etoposide (VP-16), ifosfamide, and cisplatin (three patients). Among the patients with YST, 73 had stage I disease and 3, higher-stage disease; 1 of these died due to tumor progression. In all, 56 patients were followed according to the "wait and see" policy; 9 of these needed a delayed standard chemotherapy.(ABSTRACT TRUNCATED AT 250 WORDS)
