High Dose Cyclophosphamide as an Adjunct to Radiotherapy for Advanced Seminoma

Abstract
Two patients with advanced seminoma of the testis were given single i.v. injections of high dose (1.5 and 2.0 g/m2) cyclophosphamide. Both patients experienced prompt, dramatic objective regressions without severe toxicity. Definitive radiotherapy, deemed technically unfeasible before cyclophosphamide administration, was administered subsequently. Long-term complete remissions (> 16 and 28 mo.) were attained in both patients. High dose cyclophosphamide may prove useful in selected patients with disseminated seminoma.
