Thirteen cases with sacrococcygeal teratoma were treated during the past 19 years. Ten cases with benign teratoma were all permanently cured. Among 3 cases with malignant teratoma, 2 died of local recurrence and lung metastasis, respectively. Of the remaining 1 patient whose operative staging was stage I, no further treatments were afforded. At 2 months postoperatively, however, her serum AFP showed abnormally high value and at 3 months postoperatively, a left lung metastases have developed. Subsequently, pulmonary wedge resection and chemotherapy were administered. In spite of these treatments her AFP values are keeping still high levels at present. These clinical experience may strongly suggest the importance of routine use of postoperative cancer chemotherapy even for the stage I disease of yolk sac carcinoma.
