Abstract
PURPOSECisplatin-containing chemotherapy has dramatically improved the outlook for patients with metastatic germ cell tumors (GCT), and overall cure rates now exceed 80%. To make appropriate risk-based decisions about therapy and to facilitate collaborative trials, a simple prognostic factor-based staging classification is required.MATERIALSCollaborative groups from 10 countries provided clinical data on patients with metastatic GCT treated with cisplatin-containing chemotherapy. Multivariate analyses of prognostic factors for progression and survival were performed and models were validated on an independent data set.RESULTSData were available on 5,202 patients with nonseminomatous GCT (NSGCT) and 660 patients with seminoma. Median follow-up time was 5 years. For NSGCT the following independent adverse factors were identified: mediastinal primary site; degree of elevation of alpha-fetoprotein (AFP), human chorionic gonadotropin (HCG), and lactic dehydrogenase (LDH); and presence of nonpulmonary visceral ...Keywords
