Aim:
To report long term oncologic outcomes after adjuvant radiotherapy (RT) for stage I seminoma.
Method:
We reviewed the complete data set for all patients treated at our institute between 1988 and 2005 for stage I seminoma with adjuvant RT after radical orchiectomy .
Results:
A total of 85 patients were included. The median follow-up was 15 years. The 20-year overall survival (OS) and relapse free survival (RFS) were 92% and 96.3%, respectively. No severe acute and late complications were recorded. Overall 5.9% of patients had a second unrelated malignancy.
Conclusion:
Adjuvant RT is an efficacious and safe treatment in stage I seminoma.
