[A case of malignant mediastinal germ cell tumor benefited by multidisciplinary therapy].

A 24-year-old man admitted to our hospital because of hemoptysis and left precordial pain. Chest X-ray and chest CT scan showed a mass in the left anterosuperior mediastinum. Laboratory examination revealed elevated levels of AFP (550 ng/ml), which were highly indicative of malignant germ cell tumor. Imaging examination indicated that the mass was resectable, so surgery was performed prior to chemotherapy. Histological examination revealed an admixture of seminoma, immature teratoma, embryonal carcinoma and yolk sac tumor. Because the resection performed was incomplete, the patient received three courses of combination chemotherapy consisting of CDDP, VP-16 and BLM and 40 Gy irradiation. The serum level of AFP was normal after one course of combination chemotherapy. The patient has shown no sign of recurrence for 3 years since surgery.
