Fifty-seven patients with germinal tumor of the testis treated from 1963 to 1972 were followedthrough 1975.<br>Twenty-eight patients with pure seminoma were treated by high inguinal orchiectomy and para-aortic lymph node irradiation of an average of 3, 500r. Of the 28 patients two had retroperitoneal lymph node dissection.<br>Twenty-two patients with non-seminomatous malignant tumor of the testis had high inguinal orchiectomy. As an additional treatment, of the 22 patients seven received irradiation to the para-aortic lymph nodes and six underwent retroperitoneal lymph node dissection, five of which were followed by irradiation. For non-seminomatous malignancy, an average of 4, 400r was given. Seven patients with adult teratoma had orchiectomy or resection of the tumor, and no other treatment was performed.<br>Five-year relative survival rates calculated by actuarial method were 94% (standard error 5%, effective sample size 28) for pure seminoma and 50% (standard error 11%, effective sample size 22) for non-seminomatous malignant group. The difference of survival rates between the two groups was statistically significant. Patients with adult teratoma showed 100% survival.<br>Crude survival rate of patients with metastasis manifested by physical or X-ray examination before treatment was significantly lower than that of patients with negative findings. Patients with seminoma invading periorchium or patients with non-seminomatous malignancy complaining of testicular pain had a tendency to show lower crude survivals.
