Abstract
Thirty-eight patients with extragonadal germ-cell tumors treated at Memorial Sloan-Kettering Cancer Center (New York) between 1975 and 1982 received high-dose cisplatin-based chemotherapy. Complete response was achieved in 89% of patients with pure seminoma and all complete responders are alive without evidence of disease (median follow-up time, 29+ months). Complete response was achieved in only 41% (12 of 29) of patients with extragonadal nonseminomatous germ-cell tumors; only four patients are alive and free of disease (median survival time, 18 months). Although patients with extragonadal seminoma respond well with current cisplatin-based chemotherapy, minimal improvement in CR rates has been achieved in patients with extragonadal nonseminomatous tumors. Patients with extragonadal nonseminomatous germ-cell tumors have a relatively poor prognosis when compared to patients with primary testicular tumors and investigational trials of innovative therapy should be considered.
