Abstract
One hundred forty patients with testicular seminoma were treated at the State University of New York Health Science Center at Syracuse between 1966 and 1985. Disease was classified as stage II in 32 patients (23%): stage IIA in 21 patients and stage IIB in 11 patients. All patients underwent irradiation below the diaphragm after a radical orchiectomy, and 28 underwent planned mediastinal and supraclavicular irradiation. The median follow-up was 81/2 years; 24 of 32 patients have been followed up for more than 5 years. Twenty-eight patients remain alive and well; four patients died of intercurrent disease. Two patients developed a recurrent seminoma in the mediastinum; a variant lymphangiographic pattern was shown in these patients, and they were cured. A third patient developed a nonseminomatous "recurrence" in the ipsilateral, unirradiated, inguinal nodes and is well after chemotherapy.
