Retrospective analysis of 74 cases of seminoma treated with radiotherapy.
BACKGROUND
Standard post-orchiectomy radiotherapy (RT) is accepted as a standard management option for stage I seminoma.


METHODS
Retrospective evaluation of 74 patients with stage I seminoma was performed according to the Royal Marsden staging system. All of the patients underwent RT in the Radiation Oncology Department of Gülhane Military Medical Academy between 1974 and 1995. The median age of patients was 27 years (range, 20-56). Radiotherapy was applied to all of the patients after orchiectomy for adjuvant purposes. Sixty-nine patients underwent RT while five patients who had recurrence received chemotherapy following radiotherapy.


RESULTS
After a mean follow-up period of 54 months, the 5-year overall survival rate was 98.61%, which complied with the literature. The disease-free survival rate was 90.54%. According to the World Health Organization toxicity scale, acute enteritis was 9.4% for grade I and 5.4% for grade II, while nausea/vomiting was 36.4% for grade I and 5.4% for grade II.


CONCLUSIONS
To avoid acute toxicity related to RT, prognostic risk factors should be well-known and patients with low risk factors should be monitored carefully after orchiectomy. RT should be directed to the para-aortic +/- ipsilateral pelvic lymph nodes in high risk patients. Although post-orchiectomy RT is a traditional management option for clinical stage I seminoma, the results of RT should be well-known to compare it with other treatment options (e.g. RPLND, adjuvant chemotherapy and surveillance).
