Phase II study: adjuvant single-agent carboplatin therapy for clinical stage I seminoma.

Abstract

Though para-aortal and ipsilateral iliacal radiation is the established adjuvant treatment for clinical stage I seminoma, promising results have been reported on adjuvant single-agent carboplatin therapy. We treated 43 patients with clinical stage I seminoma according to this option. They received 2 courses of single-agent carboplatin (400 mg/m2) at an intervall of 3 weeks. Therapy could be performed on an outpatient basis within 2 h. Therapy was well tolerated. Apart from minor gastrointestinal disorders and mild myelosuppression, no adverse reactions were observed. The median follow-up is 28 months. Up to now no recurrences have been noted. If the recurrence rate remains as low as after adjuvant radiotherapy, which should be proved in a phase III study, single-agent carboplatin therapy will be an alternative adjuvant approach for clinical stage I seminoma.
