Radiation therapy of pure seminoma of the testicle

An analysis of 45 patients with seminoma of the testis treated at the Radiation Oncology Department of Crawford Long Hospital of Emory University, from 1975-1986. Thirty patients with Stage I and II pure seminoma received prophylactic irradiation to the mediastinum and supraclavicular area in addition to receiving periaortic and pelvic irradiation alone. The only recurrence in the supraclavicular region was in a Stage I patient not receiving mediastinal and supraclavicular prophylaxis. No recurrences were observed in Stage II patients. The observed actuarial 5-year disease-free survival of all patients was 91.2%. In patients with Stage I disease, the actuarial 5-year survival was 93.3%. The actuarial 5 and 10-year survival of Stage II patients was 100%.
