Testicular seminoma: results of treatment at the Northern Israel Oncology Center.

The survival, and the patterns and mechanisms of failure of 41 patients with pure testicular seminoma treated at the Northern Israel Oncology Center from 1968 to 1983 were analyzed. The actuarial 5-year survival of all patients was 85.4% and of stage I patients, 92.2%. Treatment failures were analyzed. The following conclusions were reached: in order to increase the cure rate, the use of combination chemotherapy as the initial treatment modality in advanced seminoma is recommended. In cases of transscrotal approach, the scrotum should be irradiated. Adjuvant mediastinal irradiation is not needed.
