Management of malignant testicular tumors in children.

The result of therapy of 67 cases of children with malignant testicular tumors is presented. The majority of these cases were embryonal carcinoma in which metastases had occurred in the retroperitoneal lymph nodes, lungs, and bones. Long-term survival was obtained in 89% of the cases treated by simple orchiectomy followed by retroperitoneal irradiation. Two cases with metastases benefitted from chemotherapy. The prognosis of embryonal carcinoma of the testis is correlated with the age of the patient and the histologic pattern of the carcinoma; early detection and appropriate treatment are most important for its cure.
