Radiation therapy in bulky seminoma

Between 1969 and 1980, 17 patients with bulky retroperitoneal seminoma and 1 patient with bulky mediastinal seminoma were treated with radiation therapy. One patient had resection of gross retroperitoneal disease, and 1 patient had resection of gross mediastinal disease. Fifteen patients received adjuvant irradiation to the mediastinum and paraclavicular lymph nodes, and 1 patient received adjuvant chemotherapy. At last follow-up, 17 of 18 patients (94%) remain free of disease. No patient has sustained treatment-related morbidity or mortality.
