title: A multidisciplinary approach to primary nonseminomatous germ cell tumors of the mediastinum.
abstract: The introduction of cis-platinum-based chemotherapy has dramatically improved the prognosis for patients with primary nonseminomatous germ cell tumors of the mediastinum. Since 1978, 12 male patients (mean age, 29 years) have been seen with a large mediastinal mass, normal testes, and abnormal testicular tumor markers. Eleven patients had raised alpha-fetoprotein levels (median, 1,300 micrograms/L; normal, less than 10 micrograms/L), and 3 had elevated levels of the beta fraction of human chorionic gonadotropin (median, 8,000 IU/L; normal, less than 5 IU/L). Two patients were treated by primary surgical intervention followed by chemotherapy. Ten patients were treated with primary chemotherapy (cis-platinum, vinblastine sulfate or etoposide, and bleomycin sulfate), and this was followed by timed surgical excision of the tumor mass in 7. Six (60%) patients responded to primary chemotherapy with normalization of tumor markers. In this group there was 1 postoperative death and 1 recurrence. The 4 remaining patients are alive and free from disease at a mean of five years. Of the 4 patients with persistently elevated tumor markers, 2 died within six months, 1 is alive with recurrence, and 1 is lost to follow-up at three months. Patients whose tumor markers return to normal after cis-platinum-based chemotherapy have a good long-term prognosis following radical surgery. If the tumor markers remain elevated, the prognosis is poor.
