[Successful treatment of mediastinal seminoma with combination chemotherapy of cis-diamminedichloroplatinum (CDDP), vinblastine (VBL), and bleomycin (BLM)].

Complete response (CR) has been achieved in a case of advanced mediastinal seminoma using PVB therapy (CDDP, VBL, BLM). A 21-year-old man visited our department with the complaint of superior vena cava syndrome. Chest X-ray film, ultrasonography and CT scan revealed a large anterior mediastinal mass. Histological proof of mediastinal seminoma was obtained by needle biopsy. The patient was treated with a combination chemotherapy, consisting of CDDP, VBL and BLM according to Einhorn's PVB regimen. After three courses of this regimen, complete disappearance of the tumor was obtained. The patient underwent further radiation treatment (Linac: 4,000 rad), as a salvage therapy, at the anterior mediastinum, and has since been doing well without any sign of recurrence for a follow-up period of nine months.
