For the site of tumor occurence, testis was signicantly better than ovary and sacrococcygeal teratoma only in the Stage I. In the testicular tumors, there was no difference of results between the former 5 years and latter 5 years. No significant therapeutic factors were shown concerning on radiotherapy and chemotherapy. In ovarial tumors, dysgerminoma was better in prognosis than yolk sac tumor as a whole stage. The effect of radiotherapy was not shown. In sacrococcygeal teratoma, only 3 out of 25 survived over 2 years free of tumors. Two of them were in Stage IV.
