Stage I testicular seminoma: results of adjuvant irradiation and surveillance.

Abstract

The outcome of patients with stage I testicular seminoma is excellent, with only one of 364 patients (0.27%) dying of disease. In our experience, both a policy of adjuvant RT and of surveillance resulted in a high probability of cure. Our surveillance experience showed that four of five patients with stage I seminoma are cured with orchiectomy alone. The benefit of adjuvant RT was reflected in a decreased relapse rate. We have identified a number of prognostic factors for relapse in patients managed with both approaches, but further study of prognostic factors is required, particularly to identify patients at high risk of disease progression on surveillance.
