The results of treatment and the survival of 31 patients with testicular tumors admitted to the department of Urology, Osaka Medical School for 7 years from 1972 to 1978 were investigated. 1. As our principle, orchiectomy and retroperitoneal lymph node dissection were performed at the first step in the treatment leaving histological types out of consideration and thereafter chemotherapy and irradiation were done. 2. The overall observed three and five year survival rates were 78.6 and 73.2 per cent respectively. 3. The survival study on patients with different histological types of testicular tumor revealed that the observed three and five year survival rates were 79 per cent in seminomas, and 77 and 67 per cent respectively in non-seminomatous tumors. 4. The correlation between the duration from the development of symptoms to the first medical examination and the prognosis was not found. 5. High correlation between the clinical stage and the prognosis was recognized since the observed five survival rate in stage IA was 100 per cent and as more the stage advanced, the survival rate was lower. However, it was proved that even if the retroperitoneal lymph node metastasis were evidenced (stage h or II), higher survival rate was expected by retroperitoneal lymph node dissection.
