Seventeen cases of testicular yolk sac tumor, which we have experienced in the past 17 years, are reviewed in this paper. Orchiectomy combined with the retroperitoneal lymphadenectomy had been carried out in the beginning of our experiences, but since 1976, chemotherapy was introduced. Initially, vincristine, actinomycin D and cyclophosphamide were mainly chosen. Nevertheless, we lost 3 cases who had lung metastasis at initial operation. At 1983, we introduced cis-platinum as a chemotherapeutic agent. Since then, all patients, including 1 case with obvious lung metastasis, have been survived.
