Background and objectives: Germ cell tumors (GCTs) are very chemosensitive cancers, in which high-dose chemotherapy (HDCT) has been investigated as salvage therapy or as first-line treatment in poor prognosis patients. This paper presents an update of available information in order to define the status of HDCT in GCT patients.
Information sources: The authors have been working in this field, contributing to international clinical trials and to peer-reviewed journals with original papers. The material examined in this review includes articles published in journals covered by MedLine, reviews from journals with high impact factor, and unpublished data from the European Group for Blood and Marrow Transplantation (EBMT) registry.
State of the art and perspectives: The delineation of prognostic factors associated with a poor probability of survival after HDCT contributed to the selection of patients who are likely to get an advantage from HDCT and those who should be spared from dose-intensive treatment. HDCT as first-line therapy for poor prognosis GCT (IGCCCG classification), and in a salvage setting in good risk GCT (prognostic index from Beyer et al.77), has been associated with a very high rate of complete remissions and long-term disease-free survivors. However, it is important to wait for the results of ongoing randomized trials for the validation of these findings. Other strategies are required for patients with refractory GCTs. Several new treatment options are currently emerging for this subset of patients.
