Sixty cases of testicular parenchymal tumors were experienced in the Osaka University Hospital for the last 18 years (from 1957 to 1974). These cases were reviewed with regard to their clinical, histopathological and prognostic features.
1. The histopathological examination revealed that they were classified as follows; type I in 29 cases (48.5%), type II in 10 (16.7%), type III in 8 (13.3%), type IV in 7 (11.7%) and type V in 3 (5.0%) respectively, according to the pathological classification by Dixon & Moore. Of 3 non-germinal tumors out of the 60 cases, one was interstitial cell tumor and two were reticulum cell sarcomas.
2. As for the age distribution, two peaks were noted in testicular tumors, especially in cases with element of embryonal carcinoma, at the ages of 0 to 4 and 30 to 34. On the other hand, the cases with seminoma element showed one peak at the age of 30 to 34.
3. Observed 5-year survival rate in our series was 91%.
4. Although the period from the clinical onset to the definitive treatment had no apparent relationship to the clinical stage and to the prognosis, considerable relationship was observed between the clinical stage and the prognosis. Therefore, it was emphasized that the clinical staging is very important for the prognosis of testicular tumor as to determine the therapeutic procedures.
5. The observed survival rate was compared with the pathological classification and the therapeutic procedures. The result was that in non-seminomatous germinal tumor radical orchiectomy plus retroperitoneal lymphadenectomy and/or radiation therapy were for better prognosis compared with radical orchiectomy alone.
