Aims And BackgroundPure testicular seminoma has historically been treated with post-orchidectomy radiation therapy with excellent results. Recently, several aspects of the treatment of stage I seminoma have been questioned. We assessed long-term results and toxicity of patients with pure testicular seminoma treated at the Department of Radiation Oncology of S. Chiara Hospital, Trento,MethodsFrom 1953 to 1987, 102 patients with stage I pure testicular seminoma were given megavoltage irradiation with curative intent. All patients had a minimum follow-up of 3 years (maximum 37 years, median 13 years). They received a mean para-aortic/pelvic dose of 33.07 Gy (range 23.70-45.20 Gy) with different doses and fields reflecting the change in techniques over a long period of time.ResultsThe cause-specific actuarial survival at 30 years was 99% and crude survival 67%. One patient had an out-field relapse (inguinal) after a few months and was cured with radiotherapy and chemotherapy. Another patient relapsed with widespread metastases and died after 1 year of progressive disease. Early toxycity was mild and the treatment was well tolerated. Late side effects were reported in 8/102 patients.ConclusionsIn our series adjuvant radiation therapy resulted in cure rates corresponding to those reported in the literature. The 30-year actuarial survival of 99% was extremely good and the toxicity of the treatment was mild. Post-orchidectomy radiation to the para-aortic and ipsilateral pelvic nodes is a safe and effective method of preventing recurrences and is currently to be considered the treatment of choice in stage I testicular seminoma.
