[Endodermal sinus tumor of the testis in children: report of 9 cases]

Nine children with endodermal sinus tumor of testis have been treated since 1982. Their age ranged from 7 months to 5 years. Radical inguinal orchiectomy was carried out in all the patients. Four patients have received irregular chemotherapy. The follow-up showed that 4 died of the metastasis within 5 years and 5 (stage I clinically) survived without evidence of the recurrence for 1.5-7 years after operation. Serum AFP determination may give important information for the classification of the tumor and the evaluation of the follow-up results. For the cases of clinical stage I, radical orchiectomy, short course of chemotherapy, and frequent observations of AFP level are advocated.
